SUMMARY This report presents the findings of recent NI 43-101 compliant computerised 3 dimensional resource estimations for the Shirotnaia gold project, Akmola Oblast, Kazakhstan which were undertaken between November 2011 and February 2012. The study was undertaken by ACA Howe International Limited (ACA Howe) and Micromine Consulting Services UK (MCS). It is the opinion of ACA Howe and MCS that resources estimated as part of this study meet with CIM/JORC Inferred and Indicated category classifications based upon quality of input data, modelling and estimation methodology, interpolation criteria based on sample density, search and interpolation parameters, understanding and robustness of the geological model, drilling and sample density. The resource estimation has an effective date of January 9 2012 and represents a maiden NI 43-101 compliant resource estimation for the project. Alhambra has six exploration projects within the polygons of one large exploration licence area extending in aggregate to 9,262.5 km2, located in northern Kazakhstan. The area is served by a network of paved and dirt roads and a railway. There are airports at Aksu near Stepnogorsk and a medium sized airport at Kokshetau. Saga Creek Gold Company LLP (Saga Creek) is the local operating company in Kazakhstan, which is owned 100% by Alhambra. The licence area is in the Charsk Gold Belt between the Vasilkovskoe gold deposit on the northwest and the Asku gold deposits on the southeast. All operations are conducted through the 100% Alhambra owned subsidiary Saga Creek. Shirotnaia is one of six exploration projects:

• Dombraly, • Shirotnaia, • Zhanatobe, • Kerbay, • North Balusty, • Vasilkovskoe East.

The area forms part of the Caledonian-age Kokchetav-North Tienshan basin and fold system. Increasingly felsic intrusive magmatism is related to 3 orogenic cycles ranging in age from the Pre-Cambrian to the Hercynian. Mineralisation is mainly hosted by Middle to Upper Ordovician volcano-sedimentary rocks of mainly mafic and intermediate composition with interbedded lavas, tuffs and terrigenous clastic rocks. The mineralisation is described as volcano-sedimentary hosted, orogenic type. Zhanatobe, Kerbay and Vasilkovskoe East are also influenced by intrusive magmatism. Alhambra commissioned ACA Howe and MCS to compile relevant data and complete resource estimations and prepare a Technical Report on the Shirotnaia gold project, Akmola Oblast, Kazakhstan. The resource estimations and this Technical Report are prepared in accordance with CIM best practice methodology and NI 43-101 for release to the TSX and other markets, and issue on SEDAR. Resource data and resource estimation sections of the report were prepared by Mr. J N Hogg MSc, MAIG, Senior Geologist of MCS and Ms. M Sostre MSc, AUSIMM, Resource Geologist of MCS. Other sections were prepared by Mr. J G Langlands, BSc, FGS, FIMMM, C Eng or by J G Langlands and J N Hogg, together.

The scope of work, restricted to the Shirotnaia resource estimation study, included:

• Data preparation, compilation, review and validation, • Site visits, • Geological and grade domain interpretation and modelling, • Block model resource estimation for in-situ oxide, transitional and primary material, • Preparation of a Technical Report in English, using Canadian National Instrument (NI

43-101) reporting standards. The data on which this report is based are those which were available to ACA Howe and MCS up to October 30 2011. Exploration projects are ongoing and, in due course, subsequently available data may enable further updated CIM compliant mineral resource estimates to be made for Shirotnaia. The mineralisation belongs to the volcano-sedimentary hosted orogenic deposit type. The large Aksu/Quartzite Hills orogenic gold deposit lies just 3 kilometres (“km”) to the south and is actively mined by the KazakhGold Group. Originally, mineralisation was thought to be controlled by a set of northeast striking faults. It now seems more likely that mineralisation is related to the anticline-syncline inflexion line and probably to fluid barriers formed by volcanic rocks covering sediments. The most recent observations of drill core show that, at local scale, mineralisation is controlled by shear zones and contacts between fragmental and porphyritic volcanic rocks. ACA Howe and MCS have not seen any more detailed descriptions of the mineralisation. Mineralisation occurs within three main east-northeast trending structural zones, namely North, Central and South. The in-situ gold mineralisation at Shirotnaia is hosted in a sequence of mostly andesitic volcanic and volcaniclastic rocks with rare sediment horizons. There is an oxidized zone to an average depth from surface of about 20 m and a transition zone about 16 m thick below that, underlain by primary gold mineralisation. In the North zone corridor, resources are defined within discreet steep northwest dipping structures in four sub-zones over a 2.0 km strike length, to maximum depth of approximately 200 metres below surface (“mbs”). Mineralised zones are open along strike and at depth, with evidence of continuation of mineralisation indicated by trench and shallow rotary air-blast drilling (“RAB”) drilling. Within the 2.0 km strike length a 400 m section between northwest and northeast domains remains untested, offering significant potential for further immediate resources. In the Central zone, resources are defined within discreet moderate to steep northwest dipping structures over a 1.2 km strike length, to a maximum depth of approximately 200 mbs. Mineralisation is open along strike and at depth, with evidence of continued mineralisation indicated from trenching and shallow RAB drilling. In the South zone, resources are defined within shallow northwest dipping structures in three sub-zones over a 1.1 km strike length to a maximum depth of approximately 150 mbs. Mineralisation remains open along strike and at depth. An untested area of 300 m strike length between west and east mineralised domains offers significant immediate resource potential. Ongoing exploration programmes are designed to test and further quantify the oxide resources for gold extraction by cyanide leaching. Additionally, the work is designed to test the deeper, sulphidic extensions of the deposits and to identify and explore other gold bearing occurrences in the area. Raw data used in interpretation and modelling consists of data from Alhambra’s recent and 2007 diamond drilling and reverse circulation (“RC”) drilling, trench and RAB sampling exploration work undertaken by Alhambra and previous explorers.


iii

Raw data used as input to estimation consists of 2007 diamond drill hole (“DDH”) drill data, recent 2010-2011 diamond, RC drill data, verified 2007-2010 RAB data and verified 2005 trench data.

The Shirotnaia project comprises in-situ structurally controlled oxide, transitional and primary mineralisation types. Mineralisation was modelled using natural cut-off grade of 0.18g/t Au for the mineralised zones. Several mineralised domains were modelled for resource estimation. The following 13 Au grade domain models were generated across the 3 recognised deposit zones North, Central and South:

• North W1 • North W2 • North E1 • North E2 • North E3 • Central 1 • Central 2 • Central 3 • Central 4 • Central 5 • South W • South E1 • South E2

At Shirotnaia, a total of 34.6 million tonnes of Inferred resources, grading at 0.58 g/t Au for 645,000 ounces Au have been identified. An additional 2.9 million tonnes of Indicated resources grading at 0.76 g/t Au have been identified for 71,000 ounces.

A summary of in situ classified inferred resources as of February 2012 for the Shirotnaia Deposits are presented in the tables below.

iv

The Shirotnaia block model resource reporting has been based on criteria that were established according to best practice geological modelling techniques, current understanding of the geological model, historical interpretations and discussion with Alhambra personnel as described in previous sections.

Potentially economic mineral resources are being reported by use of an economic cut-off grade dependent upon the cost of mining and processing the mineralisation and the selling price of the final product.

The economic cut-off grade for Shirotnaia established using grade and block revenue factors.

Due to the early stage status of the development of the Shirotnaia deposits, a number of assumptions have been made with regard to inputs to the calculation of the economic cut-off grade for reporting.

For a single product the calculation is relatively straightforward. Resources are reported using an economic marginal cut off, determined by use of simple block revenue factor methodology and 2 year trailing average gold input price. Inputs for oxide material are based upon actual mining cost data from Alhambra’s nearby Uzboy open pit operation, and estimated costs for transitional and primary material taken from recent PEA studies undertaken on the nearby Uzboy deposit. Key input data for cut off calculation include:

• Gold price US$1,401/oz • Mining Method – open pit • Oxide processing method – heap leach • Transitional and primary processing method – gravity CIL • Recovery – Oxide 70% Transitional/Primary 85% • Oxide mining cost – US$1.7/t (in-situ) • Transitional and Primary mining costs – US$1.95/t • Processing costs – US$3.85/t (oxide), US$6.47/t (transitional and primary)

Cut off calculation is presented below for reference: Block revenue calculation – Au grade grams per tonne * Recovery * Input gold price per gram

Using the Au block grade, the above Au metal price and recovery, MCS estimated the revenue per mined block. For a mineralised block to be considered economic it must generate higher revenue than it costs to mine. For a block to be considered economic it must therefore generate greater than US$5.55/t and US$8.42/t of revenue, for in-situ oxide and transitional/primary material respectively. MCS used Micromine software to filter those blocks in the resource model with value greater than the calculated cost to mine values for economic cut-off grade determination and resource reporting.

Cut-off grades used for reporting are 0.1 g/t Au for oxide material, and 0.2 g/t Au for transitional and primary material types respectively. It is MCS’ opinion that the assumptions made for input to economic cut-off grade determination and reporting of potentially economic resources are reasonable given the current understanding of the geology, mineralisation, anticipated mining and processing methods and comparison with similar type operations.


v

Classification of resources is restricted to Indicated and Inferred, due to the following factors which introduce uncertainty:

o Limited number of valid drill holes and drill samples clustered in small areas; o The number of valid drillholes are widely spaced along domain extents; o Low number of valid samples per mineralised domain; o A low number or no bulk density data for a number of domains and sub-domains; o Lack of QAQC data, and quality control issues.

On working through the estimation process, it became clear that although the in situ deposit models are coherent and robust based upon an interpretation of combined historical and recent (valid) drilling, the domains require significant additional drill testing to increase valid input sample data numbers and sample density for both grade and bulk density determination, and improved resource block classification. Quality control sample data analysis and interpretation raised a number of issues with respect to assay precision and repeatability. This could be due to nugget effect or sampling error, and will require follow up investigation studies. Due to these reasons the restriction and selection of resource classification currently applicable to the deposit areas are deemed appropriate, particularly for in-situ domains. The current models and estimations for Shirotnaia near surface zones are by no means exhaustive. Based on available information, ACA Howe and MCS believe that the exploration and resource development of Shirotnaia is progressing well and that there is scope to develop a potentially economically viable gold resource. Strike and dip directions remain open for a large number of lodes wireframes and indicate the presence of additional structures yet to be adequately explored and exploited. Results of the block model estimations for the deposit zones modelled using limited data collected thus far for the areas are positive, and offer excellent potential for development of significant resources within the area. The interpretation of higher grading zones will no doubt further aid prioritisation of drill targeting and future resource/reserve development. A number issues and sensitivities have been highlighted as part of this study and are outlined below and expanded upon in the report. These issues ultimately impact on the robustness and confidence of the geological and resource model and should be considered for improved assessment, estimation of higher classification of resources and mine planning.

1 INTRODUCTION

This report is prepared for Alhambra Resources Limited, of Calgary, Alberta, Canada (Alhambra, the issuer, the Company) by ACA Howe International Limited (ACA Howe) and Micromine Consulting Services (MCS). Alhambra is currently undertaking exploration and development of gold deposits and prospects on their exploration and mining licences in north-central Kazakhstan, known us the Uzboy Project. Shirotnaia is one of a group of exploration projects distributed around the active Uzboy gold mine, comprising:

• Shirotnaia, • Dombraly, • Zhanatobe, • Kerbay, • North Balusty, • Vasilkovskoe East.

Alhambra commissioned ACA Howe and MCS to compile relevant data and complete resource estimations and prepare a Technical Report on the Shirotnaia gold project, Akmola Oblast, Kazakhstan. The resource estimations and this Technical Report are prepared in accordance with CIM best practice methodology and NI 43-101 for release to the TSX and other markets, and issue on SEDAR. Resource data and resource estimation sections of the report were prepared by Mr. J N Hogg MSc, MAIG, Senior Geologist of MCS and Ms. M Sostre MSc, AUSIMM, Resource Geologist of MCS. Other sections were prepared by Mr. J G Langlands, BSc, FGS, FIMMM, C Eng or by J G Langlands and J N Hogg, together. Saga Creek Gold Company LLP (Saga Creek) is the local operating company in Kazakhstan, which is owned 100% by Alhambra.

Alhambra’s Qualified Person (QP) is Elmer B. Stewart, M. Sc. P. Geol., who is a technical consultant for Alhambra. He is the QP responsible for monitoring the supervision and quality control of the exploration programmes. Site visits and meetings were undertaken by Mr. Evgenij Zhuravlyov, Senior Geologist, Micromine Consulting Services (Kazakhstan), between the dates August 12 and 14 2011, in the company of Mr. Evgeny Plyushchev, Alhambra (Saga Creek) Consulting Geologist and other Alhambra site personnel. The purpose of the site visit and meetings was to review deposit geology, receive and review the available data base, review data collection methodologies and determine modelling criteria for the purpose of completing an NI 43-101 compliant resource estimation study. A copy of the site visit report is presented in Appendix 1.

It was concluded that, for present purposes, Shirotnaia is an advanced exploration project. A substantial amount of historical and more recent exploratory work has been carried out by previous and current owners and exploration activity is ongoing. The Shirotnaia project comprises in-situ structurally controlled mineralisation types in the form of multiple discreet parallel mineralised shear zones and broader near surface supergene remobilised halos.

Several mineralised domains were modelled for resource estimation each comprising Oxide, Transitional and Primary material types:

• North W1 • North W2 • North E1 • North E2 • North E3 • Central 1 • Central 2 • Central 3 • Central 4 • Central 5 • South W • South E1 • South E2

This report is based on the findings of the MCS and ACA Howe site visits, desk study, input data review, data validation, deposit modelling, block model grade interpolation and resource estimation. The report follows the format for National Instrument 43-101 reports, and provides a template for future NI 43-101 compliant reports.

The mineral resources calculated as part of this study are considered to be reportable resource estimates compliant with the NI 43-101 reporting requirements and CIM/JORC codes suitable to be filed on SEDAR.

The sources of information used in the preparation of this report are listed in the section: References and Sources of Information and are cited in the text where appropriate.

3 PROPERTY DESCRIPTION AND LOCATION

3.1 LOCATION

The Shirotnaia exploration project is located in Figure 1. Subsequent to a licence area reduction which was implemented in 2001 (see below), the Dombraly, Shirotnaia, Kerbay and North Balusty Projects are located within the boundaries of the East Area of the Sary-Arka Licence with serial number MG 1029-D, held by Saga Creek. Zhanatobe is located within the separate Mamayskoe Area of the same licence. The Vasilkovskoe East project is located in the West Area of the same licence. The East Area extends to approximately 3,024.5 square kilometers (km²). The Mamayskoe Area extends to 350 km². The Taskuduk Area extends to 157 km². The West Area extends to 5,731 km². The total area of the Sary-Arka Licence is 9,262.5 km². The corners of these licence areas are shown in Table 1 below and the licence polygons are shown in Figure 1. All Government property descriptions utilise latitudes and longitudes and both the Sary-Arka and Uzboy Licences are described in this way. No property boundaries are surveyed on the ground.

TABLE 1. SARY-ARKA LICENCE COORDINATES The Shirotnaia exploration project of this report lies in the southeast part of East Area.

There are two exclusion areas in East Area: ‘Baylusty Deposit’ of 1.32 km² and ‘North Baylusty’ of 2 km². There are seven exclusion areas in West Area: ‘Borovoye Health Resort’ of 479 km², ‘Alexandrovskoe Deposit’ of 2.3 km², ‘Area No. 1’ of 0.04 km², ‘Area No. 2’ of 0.13 km², ‘Area No. 3’ of 0.66 km², Madeniet Nos. 1 and 2 of 68.8 km² for placer gold. The Taskuduk Area of Licence MG 1029-D does not contain any of the exploration prospects identified here and, therefore, is not mentioned further in this report. The property boundaries were located by plotting the latitudes and longitudes of the corner points of Licence No. MG 1029-D, East Area and Mamayskoe Area on Google Earth satellite imagery mosaic maps. This plot produced boundaries which enclose, or bear the expected spatial relationship with, recognisable ground features visible on the satellite imagery maps, such as the following. Shirotnaia is identified in bold text in the following list.

• Alhambra’s Uzboy open pit, heap leach gold mine (Lat. 53o21’33” N, Long. 70o59’30” E); • The Vasilkovskoe gold mine which is located about 20 km (km) west of Alhambra’s West

3.2 LICENCE AND TENURE

The following licence information which is believed to be up to date is extracted from a report by ACA Howe (2009). The legal status of the licence has not been verified by ACA Howe, who are not qualified to make any judgement on legal issues. Alhambra’s 100% ownership of Saga Creek came about as a result of various transactions reported by ACA Howe (2009), which are summarised below. In 1996 Cameco Gold Inc. (Cameco) formed a Joint Venture with Goodwin Golems LLP (Goodwin), a local Kazakhstan company based in Almaty. The Joint Venture company was named the Saga Creek Gold Company LLP (Saga Creek) and was registered in the form of a joint venture with limited liability to carry-out mineral exploration and exploitation in Kazakhstan. The Joint Venture was managed and operated by Cameco with Cameco’s interest being 80% while Goodwin’s interest was 20%. Cameco funded 100% of all expenditures. Two exploration and exploitation licences in northern Kazakhstan were initially granted to Cameco; the Sary-Arka Licence (MG 1029-D issued April 8 1996), a large area of land extending from a point immediately east of the city of Kokshetau at the northwest end of the licence area, extending in a southeasterly direction to the mining town of Bestube in the southeast. A second, smaller, licence, the Uzboy Licence (MG 719D – issued May 23 1996), was located internally within the Sary-Arka licence and thus was an area excluded from it.

The licences were consolidated and re-issued to Saga Creek on February 10 1997 and are valid for 25 years, with the initial 5 years specifically devoted towards exploration and the remaining 20 years for mining purposes. Saga Creek, under Cameco management, carried out exploration efforts on both licences during 1996 and 1997 but concentrated their efforts on the Uzboy prospect itself. In April 2000, Cameco pulled out of the Joint Venture and transferred its share and obligations to Marsa Aktiengesellschaft (Marsa) of Mauren, Liechtenstein. After the transfer, Saga Creek was owned by Marsa (80%) and Goodwin (20%). The ownership of Goodwin was sold in March 2002 to Teragol Investments Limited (Teragol) incorporated in Cyprus. Saga Creek carried out exploration activity on the Uzboy licence until the end of 2001. Marsa funded all expenditures since the transfer of ownership through to 2001. Cameco no longer retains any interest in either the joint venture or the licences. Pursuant to a Partnership Unit Purchase and Exchange Agreement dated March 21 2002 (Agreement), Alhambra agreed to purchase all of the partnership units of Saga Creek and Goodwin Golems, and as a result, obtained the licences to the Uzboy Property in exchange for 4,000,000 common shares of Alhambra. Alhambra also agreed to grant to Marsa and Teragol, a net smelter return on production from the Uzboy Property, based on up to 3% of gross revenue in the event that the weighted average price of gold is equal to or greater than US$350 per ounce and less revenue for lower gold prices. The TSX Venture Exchange approved the Transaction in October 2003. The Republic of Kazakhstan Contract on Foreign Investments had been put in force in 1997 and dictated that 50% of the initial licence was to be relinquished over time (5 years from the date of granting the licence). By September 2001, an area in excess of 50% of the total initial licence area had been relinquished in accordance with the licence conditions. Two mining allotments were granted in December 2001 to Saga Creek on areas of recognised gold mineralisation at the Uzboy prospect itself.

4 REGIONAL GEOLOGY

The Dombraly, Shirotnaia, Zhanatobe, Kerbay, North Balusty and Vasilkovskoe East project areas are all located within the northeast part of the Caledonian-age Kokchetav-North Tienshan basin and fold system. Four major elongate structural zones within the system form the framework for the region. Archaean to middle or late Palaeozoic sedimentary, magmatic and metamorphic rocks form the basement of the region. These are intruded by Cambrian to Devonian age ultrabasics, gabbros, diorites, granodiorites and granites. Major deep-seated faults cross the region. Most were generated during the Proterozoic and tend to separate the different crustal blocks. The Pre-Cambrian formations are associated with the cores of the oldest anticlinoria. They may be divided into two large complexes: Early and Late separated by a regional, folded unconformity. The Early Pre-Cambrian includes complicated, dislocated metamorphic layers ranging from Archaean to Middle Proterozoic age. This complex of rocks has two clear sub-divisions that are dramatically different in degree of metamorphism. The lower part includes rocks metamorphosed to amphibolite facies. Metamorphism of the upper part of the Early Pre-Cambrian is greenschist facies. The Late Pre-Cambrian is represented by Upper Proterozoic, slightly metamorphosed, volcano-sedimentary formations. These underlie the faunally characterised Lower Palaeozoic.


9

Cambrian rocks consist of conglomerates, conglomerate-breccias, coarse sandstones and argillites with isolated pods of limestones and calcareous sandstones. The Ordovician period is represented by thick volcanogenic formations, mainly of mafic and intermediate composition. The formations are interbedded with layers of terrigenous clastic material and tuffs and lavas. The Silurian - Devonian sequence is composed of a basal conglomerate, up to 35 – 90 m in thickness, interbedded with sandstones, tuffaceous sandstones and argillites with lenses of limestones. Overlying rocks are mainly rhyolites with subordinate andesites and tuffs. Carboniferous rocks are mainly limestones often lying unconformably on the older rocks. They are overlain by Namurian sandstones and brown coals. Large areas are covered with continental sandy-clayey lateritic deposits of the Upper Cretaceous, Palaeogene, Neogene and Quaternary age. Lacustrine and alluvial deposits are widely developed. Intrusive magmatism is related to three orogenic cycles. The oldest is represented by gneissose rocks within the Pre-Cambrian series. The early Caledonian intrusives are mainly basic in composition: gabbros, norites, also pyroxenites, peridotites and dunites. Later intrusions are of granite and granodiorite. Hercynian intrusives are mainly granites and syenites which form rounded massifs with areas of more than 100 km2. Four sets of faults are distinguished, with north-northwesterly, northwesterly, northeasterly and easterly trends. Some faults were formed during the Pre-Cambrian, others are connected with formation of the Caledonian synclinoria, or have been developed during the Hercynian orogenic cycle. All major faults feature a long history of development during which they have changed direction of displacement many times, both horizontally and vertically. Dombraly, Shirotnaia, Zhanatobe, Kerbay, North Balusty and Vasilkovskoe East lie within the Charsk Gold Belt (ACA Howe, 2009, Figure 1) which extends through the northeastern part of Kazakhstan from China to Russia, trending east-southeastwards over a width of 300 km and a distance of 1,800 km within Kazakhstan (Figure 1). The Charsk Gold Belt contains a number of substantial gold deposits and mines including those near the Uzboy Project area, which are mentioned in the Adjacent Properties section below.

5 ADJACENT PROPERTIES

The qualified persons who prepared this report have been unable to verify the available information on the adjacent properties and this information is not necessarily indicative of the mineralisation on the Alhambra property. There are two gold mines located adjacent to or close to the greater Uzboy Project area of licences, also in the Charsk Gold Belt: Aksu gold mine and Vasilkovskoe gold mine. Aksu is adjacent to Shirotnaia, located 2.3 km south of the southern boundary of the East Area of Alhambra’s Licence MG 1029-D. Vasilkovskoe is located 21.5 km to the northwest of the westernmost corner of the West Area of Alhambra’s Licence MG 1029-D and 116 km west of the Uzboy mine (Figure 1). Aksu Three gold mines in northern Kazakhstan are owned by KazakhGold in which Polyus had a controlling interest, now sold back to the Assaubayev family, namely - Aksu, Zholymbet and Bestobe (Stiskin et al., December 2010). Aksu is south of and adjacent to Alhambra’s Shirotnaia exploration project. Each of these mines is reported to process about 350,000 tonnes of ore per year (http://www.mbendi.com/indy/ming/gold/as/kz/p0005.htm#5). Correcting obvious errors reporting


10

thousands instead of millions on the website http://www.kazakhgold.com/operations/resources, as of June 2005, Kazakhstan Standard reserve and resource totals for the three mines of B+C1 reserves plus C2+P1 resources of 46.6 million ounces of gold are reported. The category B+C1 reserves, amounting to 13.2 million ounces of gold, were split between the mines as follows:

Aksu 44% Zholymbet 33% Bestobe 23%

A major exploration programme and mine expansion plan were to be implemented. On the website http://www.kazakhgold.com/documents/327/Swift%20-%20Investor%20presentation.pdf, a map indicates that these mines were expected to have resources of 8 - 10 million ounces of gold by the end of 2011. Vasilkovskoe The Vasilkovskoe gold mine, just west of Alhambra’s West Area licence polygon, is owned by Kazzinc of which 51% is owned by Glencore International AG of Switzerland (Glencore) (Stiskin et al., December 2010). Vasilkovskoe has a reported resource of 7.7 or 12.6 million ounces of gold (dates unknown) (Alhambra, January 2011a, Figure 1) and is said to be the largest gold mine in Kazakhstan. The gold is reported to be associated with tin and tungsten and the mineralisation has a low total sulphide content. Production of 955 kg of gold is recorded in 2003. Bekzatov (2004) reported the field has been developed since 1979, “proven reserves” of 370 tonnes (11.9 million troy ounces) of gold at an average grade of 2.8 g/t Au and the possibility of open pit mining to a depth of 300 m. As of 2004, about 10 percent of the deposit had been mined and processed by heap-leaching 1 million tonnes of ore per year, producing 600 to 900 kg of gold per year. Plans had been made to increase production to 7.4 million tonnes of ore by constructing a new gold extraction plant which was put on stream in 2010. More recent, detailed information on the mine is difficult to find. Glencore itself reports that Glencore owns 51% of Kazzinc and Kazzinc owns 100% of the Vasilkovskoe gold mine and 48.3% of the Novoshirokinskoe gold mine in Russia. Together, Kazzinc’s six base metal and precious metal mines have an annual production capacity of 300,000 tonnes of zinc metal; 130,000 tonnes of lead metal; 280,000 tonnes of copper concentrate; 700,000 troy ounces of gold and 6,000,000 troy ounces of silver (http://www.glencore.com/kazzinc.html ).

6.1 SHIROTNAIA - PROPERTY DESCRIPTION AND LOCATION

Available information on property description and location, including licences and tenure, which is common to all the exploration projects, may be found above in the report section with that name. The Shirotnaia Project area is situated in the southern part of the East Area polygon of Alhambra’s MG 1029-D Licence within the Akkol District of the Akmola Province and is 116 km southeast of Alhambra’s operating Uzboy open-pit gold mine and 8 km north of the Aksu mining complex and 20 km north of the town of Stepnogorsk. The operational centre of the Shirotnaia project is the highly gold-anomalous area and rock volume defined by trenching and various types of drilling, independently located on Google Earth at Latitude 52°30'49.01"N and Longitude 72°00'17.32"E. The gold anomaly as delineated by the 0.1 g/t Au contour in RAB samples of soil and saprolite, maps as an irregular lens shape and extends over a strike length of 4.2 km east-northeast by up to 0.9 km north-northwest and extends over an area of 1.8 km2. Within this anomaly there are many others defined by the 0.5 g/t Au contour. The anomaly is not closed along its southern flank over a distance of about 1 km due to the fact it is covered by a large waste pile from a uranium mine nearby. It is not properly closed, apparently, along about 0.5 km of its southwest flank due to a swamp. The project area is located well within the boundaries of Alhambra’s East Area licence block (MG 1029-D). The ongoing exploration programme is to test and quantify the oxide and sulphide gold resources. All enterprises in Kazakhstan must conduct environmental monitoring. Provisions are made in three stages:

• prior to the beginning of operations; • during the progress of work; • after the completion of work.

Details of ecological monitoring are not available to ACA Howe at this time.

6.1.1 ACCESSIBILITY, CLIMATE, LOCAL RESOURCES, INFRASTRUCTURE AND PHYSIOGRAPHY

Stepnogorsk (pop. 60,000) is the nearest town to the Shirotnaia project area and is the site of Alhambra’s gold extraction plant and operational headquarters of its subsidiary Saga Creek. Tarmac roads connect the project area to Aksu mining complex and railway station 8 km to the south-southwest and to Stepnogorsk 20 km away in the same direction. The project area lies on part of an extensive plain with low relief ridges and wide internal-drainage valleys and lake depressions. Elevations range from 182 m to 321 m above sea level, with local relief of 1 to 5 m, less frequently 8 to 10 m. The average altitude in the vicinity of Shirotnaia is 263 m. A large elliptical waste dump about 2 km by 1.5 km in plain view and up to 40 m high, derived from a nearby uranium open pit, lies immediately to the south of the Shirotnaia prospect and appears to encroach upon and cover the southeastern edge of the oxide gold potential. Exploration appears to have been restricted to some degree by a swamp which covers part of the southwest flank of the prospective ground. In the winter of 2010-11, Alhambra started exploring the ground below the swamp with a line of four core holes. The region is characterised by widespread shallow swampy depressions, fringed by small bushes and aspen and birch forests. It belongs to the tipchak-feathergrass steppes of North Kazakhstan. The swamps regularly dry up, appearing again after the spring melting of snows and in rainy periods. However, this landscape has been disturbed by mineral exploration and mining activities.


18

The region has a sharp continental climate. The coldest months are January and February with average monthly temperatures of -17 °C to -20°C with the minimum reaching -35°C. June and July have the highest average monthly temperatures of 18 °C to 22°C with the maximum reaching 35°C. It starts to freeze in September, and warm weather comes in the middle of May. Hence, there is a restriction on the operating season for exploration and this will probably also apply for open-air mining operations. Annual rainfall ranges from 250 to 300 mm. The long-term average yearly precipitation is 268 mm. The major portion of precipitation falls in autumn and winter. July and August are the rainiest summer months. The prevailing wind directions are westerly and southwesterly in summer; northwesterly and westerly in winter. High winds and dust storms bring problems for farming prior to the hot summer season. Electric power will be readily available from the nearby mining complex of Aksu. Adequate quantities of potable and process water for mining needs could be supplied from local boreholes. Factors such as plant sites, potential tailings and waste disposal sites will be considered as the project develops. With regard to the sufficiency of surface rights for mining operations, the availability and sources of power, water, mining personnel, potential tailings storage areas, potential waste disposal areas, heap leach pad areas and potential processing plant sites, no difficulties are foreseen by ACA Howe since mining is clearly an acceptable and very active industry in this general area, Alhambra is already producing gold from Uzboy, the land is generally flat and sparsely populated and this advanced exploration project is relatively close to the town of Stepnogorsk, Alhambra’s operational headquarters.

6.2 SHIROTNAIA - HISTORY

Mineralisation was discovered at Shirotnaia by regional scale prospecting during the Soviet Era. No details of this work are available to ACA Howe. The first modern exploration by Alhambra in 2002 to 2004 produced very encouraging results as described below.

6.2.1 HISTORICAL MINERAL RESOURCE AND MINERAL RESERVE ESTIMATES

In-house Kazakhstan standard resource estimates to a depth of 30 m were made in 2007 by Alhambra’s wholly owned subsidiary Saga Creek (Plyushchev, E., 2011. pers. comm., 26 January.) and are summarised in Table 2 below.

6.3 SHIROTNAIA - GEOLOGICAL SETTING

6.3.1 SHIROTNAIA - REGIONAL GEOLOGY

The regional geology is common to all the exploration projects and is described above in the report section with that name.

6.3.2 SHIROTNAIA - LOCAL AND PROPERTY GEOLOGY

The project area is underlain by a Middle Ordovician volcano-sedimentary sequence, cut by Late Ordovician to Devonian intrusives. The volcano-sedimentary sequence, primarily andesitic tuff, volcanic breccia, porphyritic andesite-dacite and tuffaceous sandstone, rare limestone, siltstone, fine-grained sandstone, and felsic tuff, is intruded by Late Ordovician sub-volcanic porphyritic andesite-dacite and lens shaped bodies of diorite. The supracrustal rocks are gently folded, although some tight folding is reported in the south.

6.4 SHIROTNAIA - DEPOSIT TYPES AND MINERALISATION

The mineralisation belongs to the volcano-sedimentary hosted orogenic deposit type. The large Aksu/Quartzite Hills orogenic gold deposit lies just 3 km to the south and is actively mined by the KazakhGold Group. Originally, mineralisation was thought to be controlled by a set of northeast striking faults. It now seems more likely that mineralisation is related to the anticline-syncline inflexion line and probably to fluid barriers formed by volcanic rocks covering sediments. The most recent observations of drill core show that, at local scale, mineralisation is controlled by shear zones and contacts between fragmental and porphyritic volcanic rocks. ACA Howe and MCS have not seen any more detailed descriptions of the mineralisation. At Shirotnaia, mineralisation occurs within three main east-northeast trending structural zones, namely North, Central and South. The in-situ gold mineralisation at Shirotnaia is hosted in a sequence of mostly andesitic volcanic and volcaniclastic rocks with rare sediment horizons. There is an oxidized zone to an average depth from surface of about 20 m and a transition zone about 16 m thick below that, underlain by primary gold mineralisation. In the North zone corridor, resources are defined within discreet steep northwest dipping structures in four sub-zones over a 2.0 km strike length, to maximum depth of approximately 200 mbs. Mineralised zones are open along strike and at depth, with evidence of continuation of mineralisation indicated by trench and shallow RAB drilling. Within the 2.0 km strike length, a 400 m section between northwest and northeast domains remains untested, offering significant potential for further immediate resources. In the Central zone, resources are defined within discreet moderate to steep northwest dipping structures over a 1.2 km strike length, to a maximum depth of approximately 200 mbs. Mineralisation is open along strike and at depth, with evidence of continued mineralisation indicated from trenching and shallow RAB drilling. In the South zone, resources are defined within shallow northwest dipping structures in three sub-zones over a 1.1 km strike length to a maximum depth of approximately 150 mbs. Mineralisation remains open along strike and at depth. An untested area of 300 m strike length between west and east mineralised domains offers significant immediate resource potential.

6.5 SHIROTNAIA - EXPLORATION AND DRILLING

The first modern exploration programme by Alhambra began in 2002-2004 and produced very encouraging results. Soil sampling along a 500 by 50 m grid, producing 609 samples, was followed by trenching and a limited amount of rotary air blast drilling along 5 lines 40 to 80 m apart. Five mineralised zones 240-540 m long and 1-20 m wide were defined. Exploration continued in 2005 with trenching and KGK hydro-core lift drilling on 40 m and 80 m spaced lines. Some 2,100 cubic metres of trenches were dug and 2,023 channel samples taken. KGK holes were drilled 10-20 m apart to depths of 30 m or less. Some 3,800 m were drilled and 1,864 samples taken. It was established that the shape of the mineralisation zone is complex but trends northeastwards and dips northwestwards at angles of 60 to 75 degrees. It extends up to 700 m and varies in width from 97 m in the central part to 2 to 9 m on the flanks. Several smaller parallel zones were also outlined. In 2006, exploration concentrated on the previously established mineralisation and the possibility of a southwest extension. A total amount of 3,845 cubic metres of trenching on lines 40 m apart was carried out. A total of 3,711 channel samples were collected. KGK drilling was carried out to the northwest and northeast of the established mineralisation along lines spaced at 80 to 120 m, with 10 m between the holes. Average depth of the drilling was 28 m and 197 holes, totalling 5,444 m were drilled and 2,083 samples were taken. An additional ore body dipping northwest at an angle of 45 to 50 degrees was discovered to the southeast of the main mineralisation zone. In 2007, RAB drilling sampled the northeast and southwest extensions of the known mineralisation and core drilling was completed within the central area. A total of 818 RAB holes on a 200 x 50 to 20 m grid totalling 3,760 m of drilling, collecting 1,120 samples, along with 18 core holes totalling 2,117 m of drilling, collecting 2,000 samples were completed. The RAB holes established a northeast extension to the mineralised zone, while the core holes confirmed the continuation of the mineralisation to depth and its dip to the northwest at an angle of 60 to70 degrees. In 2008, exploration continued with RAB drilling at the eastern, western and south-western flanks of the previously discovered mineralisation. There were several successive stages of drilling along 1,000 x 50, 500 x 50, 200 x 100 and 40 x 5 m grids. Most of the holes were 4 m deep, targeting geochemical anomalies in alluvium and saprolite. In total, 36,800 m was drilled and 17,050 samples were taken. This sampling returned significant although patchy gold anomalism at the eastern and southwestern flanks while to the northeast, gold anomalies were traced to a distance of 1,800 m from the previously established mineralisation. Results up to 2008 are summarised in the following paragraphs. Soil sampling established the presence of a greater than 50 ppb gold anomaly with peaks of 1.0 ppm Au. It is elongated in a northeast direction, 3.2 km long and 1.6 km wide and covers an area of 3.2 km2. In its central part it remains open to the south below the old waste dump from the Aksu uranium open pit. Gold anomalism in soil is supported by a greater than 100 ppb silver anomaly, which also continues to the northeast. This indicates a probable plunge of the gold mineralisation zone in a northeast direction. Only a part of the established gold and silver soil anomalies was then checked by RAB drilling. Using the maximum gold grade in a hole, this established an anomalous area with more than 100 ppb gold, about 4.2 km long and 0.9 km wide. Gold grades in soil and saprolite inside this area reach 51.6 g/t Au.


21

RAB drilling demonstrates an extension in a northeast direction of the gold anomaly in soil and in saprolite at depth, confirming a probable plunge of the mineralisation in this direction. The entire RAB anomaly delineates an area of 1.8 km2 which presents an important target for future exploration. The area trenched covers only the southwest part of the established RAB drilling anomaly. Trench sampling results outlined a zone of mineralisation about 1.7 km long and up to 54 m wide, containing several parallel areas of gold mineralisation with average grades up to 2.87 g/t Au. The zone is not well defined since some trenches did not penetrate the alluvium above the saprolite. Trench sampling results also demonstrate another northeast trending mineralised zone, oblique to the main one and situated to its south. It seems that the second zone has a similar width and similar average grade. Higher grade mineralisation could occur at the possible intersection of these zones. A limited amount of KGK drilling covering only a small part of the RAB anomaly indicated a zone of mineralisation with a complicated shape 700 m long and 2 to 97 m wide. This is because the majority of the samples characterise the gold distribution in saprolite only, not in hard rock. However, KGK drilling confirms the possible extension to another zone at least 400 m to the northeast and the presence of parallel zones southward of the main zone. In the central part of the main zone, 13 core holes were drilled and 5 were drilled on its southwest extension. The southwestern holes established only a low grade mineralised zone with the best intercept being 24 m with 0.54 g/t Au, while the central holes not only confirmed the presence of mineralisation, but a continuation which remains open at depth past 120 m. Core drilling also established consistently higher grades at depth reaching up to 13.5 g/t Au. These higher grades obviously represent a sulphide zone of gold mineralisation. In 2010, further core drilling was carried out to test for depth extensions to the northeast. Nine core holes were drilled for a total of 1,140.5 m to down-hole depths of 100 to 170.9 m. Seven holes were drilled towards the southeast at collar angles of 60 degrees from the horizontal and two holes were drilled at the same angle in the opposite direction. The results show some significant near surface and deeper gold intercepts presented in Table 3 below.

Four out of nine holes proved significant deep intercepts indicating sulphidic gold mineralisation at depth. These are not yet integrated with core drill data of 2007 or interpreted into a coherent structural model. In 2010 Alhambra completed a phase of shallow RC drilling, comprising of 43 holes for 2,249m. In late 2010 and throughout 2011, Alhambra completed a programme of 49 diamond core holes testing oxide, and primary mineralised zones. Significant intercepts from recent 2010-2011 Alhambra RC and DDH drilling conducted on the

6.6 DRILLING

The following information was compiled from Saga Creek’s report of 2007 (Begayev et al., 2007) and modified in consultation with Saga Creek, for the description of sampling methodologies prior to the recent 2010-2011 exploration programmes. Slurry sampling was conducted during RAB drilling. A 1.5 to 2.0 kg sample of the cuttings was split from the discharge and then further split into a sample for analysis and it’s duplicate. For the recent (2010-2011) exploration programmes, geological exploration works on the deposits were carried out according to conventional methods. Documentation of the mine workings and holes was carried out directly at the mine sites. Sampling was conducted at the Saga Creek gold processing plant. Core documentation was carried out during the core drilling process on a daily basis. Geological information was entered into the logs recording drilling intervals (runs), the core length, % core recovery, core sketches of separate fragments, lithologies and mineralisation, sampling intervals and sample numbers. During the performance of geological work the hole is closed by the district geologist and check measurements of the hole are taken. Once the hole is completed, core handling and processing is undertaken, which includes geological logs, drilling logs (conducted by the drilling foreman with filling in the drilling parameters and possible geology-technological information and issues), start and completion dates of hole drilling, survey measurement. Drill core was routinely photographed. Drill holes documentation for logging and processing is hardcopy only, later transferred to electronic format for utilisation in 3D modelling software. Core boxes were laid out in drill sequence for processing and sampling. The geologist marks sample intervals, putting sample labels along sample interval boundaries strictly identified by the logging and sample documentation. MCS have reviewed geological logs and are satisfied they capture the pertinent and relevant information. Following the geological documentation and the identification of ore zones (mineralisation) and sample interval marking core is cut along the long axis of the core. Half core for the entire length of the drill hole is collected for submission to the laboratory. Core cutting is made under the supervision of the geologist, at Stepnogorskaya Mining Enterprise facility, a subcontractor of the drilling company. Diameter of diamond disc is 400 mm. Soft or broken material is split in half by hand. Once the core is split into two halves, the sampler selects half core samples and places into plastic sacks according to the sample intervals. Paper label with sample information (site, hole number, sample number, sample interval, family name of the geologist, date of sampling) is inserted into the sample sack. Hole and sample number are signed on the sample sack. All samples from the holes are sent to the core storage facility, where sample weighing and sample group formations for the sample preparation are performed. These samples are weighed (scales type РН-10Ц134), with a scale accuracy of 0.05 g and are entered in the sample registration log. Following the cutting, core boxes for the drill holes remaining core are closed and transported to the Saga Creek Gold Company’s core storage warehouse.


28

Later, if necessary, metallurgical test samples are selected from the remaining core for mineralogical and technological studies. MCS and ACA Howe consider drill core handling and processing methodology satisfactory. For RC drilling, a standard and acceptable approach and practice is employed. The rock chips coming from the hammer to the cyclone through dual tube were split using a rifle splitter by the drilling contractor under the supervision of the Saga Creek geologists. Each metre of hole was sampled. The average sample weight was 5 kg. Samples were packed in double cotton bags, properly marked and sent to Stewart Assay and Environmental Laboratories – Kyrgyzstan. Standards, blanks and duplicates were inserted into the sample stream submitted to the laboratory after each twenty-fifth routine sample.

6.6.1 TRENCHING

Trenches were dug by excavator along 40 and 80 m spaced profiles to the depth of 1.5 m. The trenches were mapped and sampled manually by taking 1 m long channel samples. The samples’ weights ranged between four and seven kg.

6.6.2 BULK DENSITY

In 2007-2009 determination of a bulk weight and natural moisture of ore in situ was completed on C* prefix DDH drill core using paraffin-lined samples applying standard methods in the laboratory of Reaktiv LLP. The total number of 413 samples were collected and measured for bulk density determination. Bulk density determinations are yet to be taken for recent Alhambra exploration drilling (2010-2011 drill programmes). Bulk density for use in current resource estimations is discussed further in section 6.11.14 of this report.

6.7 SHIROTNAIA - SAMPLE PREPARATION, ANALYSES AND SECURITY

Sample preparation, analysis and security for the Shirotnaia project follows very similar protocol procedural history to that of Alhambra’s Uzboy and Dombraly projects. Between the years of 2002-2005 the following types of assay works were carried out:

• Fire assay of core, trench and chip samples for gold; • Atomic-absorption analysis for gold of core and chip samples; • Combined samples analysis.

Fire assays were done at Tsentrgeolanalit CJSC laboratory (Karaganda), atomic-absorption analysis was carried out in Reaktiv LLP and Kvarts Chemical Analytical Laboratory. Combined samples were analysed in Tsentrgeolanalit CJSC.


29

Fire assay analysis was undertaken for gold, atomic-absorption analysis for gold, copper, lead, zinc and silver, spectral assay for 16 elements, complete silicate analysis, neutron activation analysis for platinum, chemical analysis for total sulphur, sulphide sulphur, sulphated sulphur. Internal geological verification of fire assays was conducted in Tsentrgeolanalit CJSC, external geological verification – in the laboratory of Kazmekhanobr. Duplicate samples were sent for internal and external verification. Prior to 2009, samples were prepared at commercial facilities within Kazakhstan. In 2002-2004, the sample processing was carried out in the Reaktiv LLP (Stepnogorsk), in 2005-2009 – in Quartz Chemical Analysis Laboratory. Over the entire period of gold mine exploration, grinding of the gold samples was carried out at K equal to 0.5. In 2009, exploration works samples were prepared in the sample preparation facility of Saga Creek Gold Company’s gold processing plant in Stepnogorsk. Sample processing was performed using the Richard-Chechett' formula Q = kd2 at k = 0.5. Experimental validation of the coefficient of uneven mineralisation was carried out on the field in 2005. Subsequent to drying, samples are sent to the first stage jaw crusher, where sample material is grinded to approximately 7 mm. Following the first stage of grinding, crushed material is sent to roller crusher, where it is grinded up to 1 mm. Sample rescreening is performed following the roll crusher through the sieve with a cell of 1 mm. Material not passed through the sieve returns to regrinding in the roll crusher. After the second phase of fragmentation and reduction by the Jones index, the bulk of the samples which have been crushed to 1 mm enter the geological sample storage as a geological sample duplicate, while sample weighing approximately 0.75 kg is reduced to a particle of size 200 mesh (disk pulveriser). The scheme employed for core sample processing is shown in Figure 8. Batches for both atomic absorption and fire assay are selected from the sample material, plus samples for the internal and external control. Remains of analytical sample are sent to the sample storage as analytical duplicates. Sample duplicates are stored in a specially designed secure sample storage building of the gold processing plant. All duplicate (residue) samples are strictly controlled. Geological sample duplicates are packed in sacks, sacks are signed, stacked by holes, and are kept on special shelves. All samples are numbered and easily accessible. All instruments used for crushing and sample reduction are equipped with special instructions for operators. The sample preparation workshop is kept clean. After every sample preparation, all appliances and countertops are cleaned using compressed air, but equipment is not cleaned by rushing inert material such as granite or glass. Sample preparation methodology at the SCGC facility is considered satisfactory.

For the 2010 and 2011 exploration programmes, sample preparation and fire assay were done by Stewart Assay and Environmental Laboratories – Kyrgyzstan and used the following methodology: Samples were crushed to -2 mm, mixed and split into two 200 g sub-samples. One sub-sample was pulverised to –200 mesh and the other sub-sample was retained for reference purposes. A 30 g sample of the –200 mesh material was used for fire assay atomic absorption finish. Stewart Assay and Environmental Laboratories, as a part of ALS Group, have stringent quality assurance and quality control procedures and does have an International Standard Organization (“ISO”) 17025 accreditation. For trench samples (2005), sample preparation and atomic absorption analysis was completed by Chemical and Analytical Laboratory Quartz LLP located in Stepnogorsk using the following procedure: samples were pulverised in a jaw crusher to -1 mm, mixed and split into two 0.75 kg subsamples. One sub-sample is ground to -200 mesh and the other sub-sample is retained for reference purposes. A 10 g sample of the -200 mesh material is used for atomic absorption. For internal control purposes, 10% of the samples are re-analysed. Most of the samples returning more than 0.3 g/t Au were re-assayed by fire assay. The external control for the results of Quartz LLP was done by Centergeoanalit Ltd. located in Karaganda, Kazakhstan. Standards, blanks and duplicates were inserted into the sample stream submitted to the laboratory for analysis. Both laboratories, Quartz and Centergeoanalit, are certified in the Republic of Kazakhstan but do not have any International Standard Organisation rating.

6.8 SHIROTNAIA - DATA VERIFICATION

6.8.1 QA/QC ANALYSIS

The quality assurance/quality control (QA/QC) analysis comes from a combination of information from the geological exploration reports for the project, quality control data and information and observations gathered by MCS during the project site visit.

6.8.2 INTRODUCTION

Quality control monitoring is undertaken to ensure that the chemical data used are as reliable as possible to meet the objective of the exploration and resource development program. In advanced exploration projects, quality control and assurance programs are designed to ensure the high integrity of data fit for the purpose of obtaining reliable and accurate, reportable mineral resource and reserve estimates. There are three fundamental aspects to Quality Control:

• Accuracy - How close are the assays to the ‘true’ content of metal in the samples? • Precision - How repeatable are the values from the samples? • Sampling Errors - Sampling errors and laboratory errors that may influence the representativeness of a sample and the representativeness of the assay result from that sample.

6.8.3 QUALITY CONTROL SUBMISSION For an NI 43-101 compliant study, it is necessary to present a QA/QC assessment study.


32

The frequency of QC sample submission will vary depending upon the type and stage of the exploration program, for example: • When dealing with a soil sampling program where the requirement from the data is precision rather

than accuracy, the submission of expensive external ‘certified’ standards is wasteful. Routine submission of ‘In house’ standard material, along with a few duplicated sites near any known mineralisation may well suffice. Overall, quality control samples need not exceed say 1 in 50 (2%).

• When drilling a prospect which has a good chance of becoming a resource, a higher proportion of

QC samples will be required. These might comprise of ‘in house’ standards and blanks, duplicates, and certified standards. In addition, it may be prudent to conduct occasional but regular cross checks of mineralised samples at other ‘umpire’ laboratories (along with QC samples).

• A general industry ‘rule of thumb’ for the proportion of QC samples submitted for drill

programmes is 5%, comprising of 2% ‘Certified Reference Material’ (CRM) samples, 2% Duplicate samples and 1% Blank samples. In practice, there is a requirement to include in the sample run 1 CRM every 50 samples, 1 Duplicate every 50 samples and 1 Blank every 100 samples.

At the Shirotnaia project QAQC sample data is currently available for the 2005 T* prefix trenches, the ES* and SP* prefix 2007-2010 RAB and the 2007-2010 C* prefix, and all 2010 and 2011 RCV and DDH drill holes.

6.8.4 QUALITY CONTROL SAMPLE MATERIALS Quality control is assessed from the evaluation of analytical results from a combination of samples:

• Primary Standards – Sample of known metal content and chemical characteristics. These can be externally sourced commercial standards (CRMs) or company ‘in house’ standards.

• Blank Samples – Samples that contain none of the metal in question. These are generally sourced in-house from barren drill spoil, however quantities of material suitable for Blank standard material can be purchased commercially (road base/gravel).

• Duplicates – These are splits of drill core, RC/Aircore/RAB drill cuttings, and outcrop

samples from the same sample interval. In the present project only the exploration campaigns drilled from year 2010 present the fullest QAQC procedure analysis. During the previous campaigns no blank or standard samples were introduced in the analysis process, only duplicate samples, based in the soviet style exploration data check requirements.

6.8.5 QUALITY CONTROL ASSESSMENT

6.8.5.1 PRIMARY STANDARDS

Primary standards are used to verify the accuracy of analyses reported by mineral testing laboratories. They are homogenised samples that have been analysed numerous times, usually by definitive techniques, so their ‘true’ metal content and the inherent variability therein are known.


33

Two types are used:

• ‘In-house’ Company Standards – In the present project ‘In-house’ company standards were not used.

• Commercial (CRM) Standards – CRM samples sourced from SGS Australia were routinely submitted for assaying with core to test laboratory accuracy. A variety of CRM’s were used, representing high and low gold grades, and oxide and sulphide ore. CRM’s were routinely included in sample batches sent to the Stewart Kyrgyzstan lab for fire assay. A total of 8,487 samples were analysed from the diamond drilling program and 2,555 for the RC program.

In 2010, a set of CRM’s were purchased from Rocklabs (New Zealand), via the consultant lab GMAR Development (Nevada, USA), which are now preferred CRM sample for submission.

6.8.5.2 BLANK SAMPLES

It is common practice to include samples of material believed to be barren of the metal/mineral being sought to ensure that no background drift occurs at the laboratory and that no gross contamination is taking place. In the present study two different blanks were used, one was a standard CRM sample with a known very low grade of 0.003 ppm Au, and the other, was an in-house made sample with a grade <0.010 ppm Au (lower detection limit of the analytical lab).


34

6.8.5.3 DUPLICATE SAMPLES

A common method of monitoring QC is to submit duplicate samples. Duplicate samples analysis allows for the determination of the natural nugget and sample error, pulp repeats allow for the determination of assay precision. However, and of considerable importance, it does not monitor accuracy. A total of 451 pulp and 1,435 lab duplicates were taken for the 2010-2011 exploration programmes. No field duplicates were submitted.

6.8.6 QA/QC ASSESSMENT Once the QC samples have been included in a batch, it is essential that the results are evaluated. The samples sent to the lab to be analysed were divided into four batches, with a total of 11,042 (8,487 samples form diamond drilling and 2,555 from RC drilling). The QA/QC samples submitted in each batch are detailed in Table 7.

For diamond drilling there were submitted 372 blank samples (which represent 4.3% of the total samples analysed); 340 standard samples (which represent 4.0% of the total samples analysed); and 349 pulp duplicate samples (which represent 4.1% of the total samples analysed). Stewart Kyrgyzstan lab introduced, as in-house QAQC procedure, 198 lab duplicate samples (pulp duplicates) in the DDH 2010 batch’ samples, 332 in the RC and 905 in the DDH 2011.

In RC drilling there were submitted 102 blank samples, 102 standard samples and 102 pulp duplicate samples (each type of the QA/QC samples represent 4.0% of the total samples analysed).

In the drilling programmes prior to year 2010, only duplicate samples were added to the sampling analysis process, as QA/QC methodology. Based on the Soviet style, the samples duplicated were prepared as pulp duplicates in the laboratory where regular samples were prepared, and then they were analysed in the same analytical lab and in a different analytical laboratory, as an external control. 28 drill chips samples were duplicated in Reaktiv laboratory and then re-analysed in Kazmehanobr laboratory (original samples were analysed in Centergeoanalit laboratory). 135 core samples were duplicated in Quartz laboratory and then re-analysed in Kazmehanobr laboratory (original samples were analysed in Centergeoanalit laboratory) (Table 8).

Results from CRM’s, field duplicates and lab duplicates are assessed in the following section. 6.8.6.1 MONITORING OF STANDARDS – ACCURACY Micromine software was used to create the analyses of the standards accuracy. The known metal content from the standard sample is added to the graphs below as a (black) horizontal line (called Ref Value), and +/- 1, 2 and 3 standard deviation lines as Upper or lower warning limits. There are statistical objections to using +/- 2 standards deviations as action limits, as by definition 5% of all determinations will cause ‘failure’. This is where common sense is required. An alternative common practice in statistical assessment of standard data is to apply an arbitrary +/-10% of the ‘true’ expected value as the action limits for a standard. The results obtained were plotted on a graph for each element of each standard sample.

The review of external standard values plotted on control charts for diamond drilling 2010-2011 program and RC drilling 2010 programme indicate that the results for Au fall within acceptable limits of one standard deviation of the CRM, indicating analysis done by Stewart Kyrgyzstan Lab is reasonably accurate.

6.8.6.2 MONITORING OF PULP DUPLICATES – PRECISION

Analysis of pulp duplicate precision has been studied by Scatter Plot, using Micromine software. Scatter plots are the simplest way to display duplicate data and are created by simply plotting paired data on the x and y axis. In addition, a useful tool to describe the correlation between paired data sets is to add a trend line to the graph and to calculate a correlation coefficient from the data (for example R2) which is a value between 0 and 1, 0 indicating no correlation and 1 being perfect correlation. Adding a trend line and displaying correlation coefficients are simple to add using the Excel graph wizard tool. The precision value shown in the graphs is an indication of variability in the differences between individual X-Y values, relative to the average X value. A perfect result has a precision of zero. Values greater than zero represent an increasing amount of deviation. For gold, in coarse duplicate, best level of precision is 20%, and acceptable 40-30%, and for pulp duplicate best level of precision is 10%, and acceptable 20% (Abzalov, 2008). In the present project pulp duplicates were inserted in the sampling analysis procedure in the drilling campaign previous year 2010 and post year 2010. In the drilling programs previous to year 2010 based in the Soviet style, the samples duplicated were prepared as pulp duplicates in the laboratory where regular samples were prepared, and then they were analysed in the same analytical lab and in a different analytical laboratory, as an external control. The samples analysed were from drill chips and drill core, for that in the present study each type of sample is studied separately. In the drilling campaigns during 2010 and 2011 the methodology was changed, and the pulp duplicates samples were analysed in the same laboratory where the original samples were analysed.

In the samples’ analysis previous to year 2010 pulp duplicate samples were done for core samples and drill chips. Those duplicates samples analysed in the same analytical laboratory as the original samples, and they were also analysed in an external control lab. In Figure26 and Figure 28 it can be seen that the precision for drill chips pulp duplicates and core pulp duplicates the precision value achieved in the re-analysis done in the original lab is under 20% acceptable value considered by Abzalov (2008) (19.96% for core samples and 18.39% for drill chips). They also present a high correlation of data at R2 = 0.9644 for drill chips and R2 = 0.9739 for core samples. In the other hand Figure 27 and Figure 29 show that in the pulp duplicate analysis done in an external control lab the precision value achieved pass the 20% acceptable limit established by Abzalov (2008) (27.66% for core samples and 26.32% for drill chips). The squared coefficient correlation is R2 = 0.9383 for drill chips and R2 = 0.9658 for core samples. No additional information was given about the pulp duplicate procedures followed by any of the laboratories (nor the preparation lab or the different analytical labs). Due to that lack of information MCS doesn’t consider relevant the precision values obtained in the external laboratories analysis. Unless check standards are used, there is no guarantee that either lab is producing an accurate result. 6.8.6.3 MONITORING OF LAB DUPLICATES – PRECISION Stewart Kyrgyzstan laboratory has a policy to insert pulp duplicates of some of the samples are part of its in-house QA/QC process. In the present project these laboratory duplicates have been studied in the same way as the pulp duplicates inserted in each batch of samples (section 6.8.6.2).

Diamond drilling 2010-2011 lab duplicates has low acceptable precision result in the sample pairs. The precision value obtained is 22.17%, which would represent a low-acceptable precision, close to the 20% acceptable value described by Abzalov (2008), although it presents an extremely high correlation of data at R2 = 0.9980.

RC Drilling 2010 Lab Duplicates

Figure 31: Scatterplot comparison between original RC drilling drillhole fire assay samples and lab duplicates.

RC drilling 2010 lab duplicates has a good precision result in the sample pairs. The precision value obtained is 16.08%, which is under the 20% acceptable precision value described by Abzalov (2008), and it presents an extremely high correlation of data at R2 = 0.9988.

6.8.6.4 MONITORING OF BLANKS – ACCURACY

Blanks are essentially standards with zero grade. Blank sample assay data should be plot on a control chart as described before for the monitoring of standards. In the present study CRM samples with a very low grade of 0.003 ppm Au and in-house made samples of 0.005 ppm Au were used as blank samples, when the detection limit of the analytical laboratory was 0.01ppm. In the following graphs, done for plotting blanks samples, it was used a blank value of 0.01 ppm.

In the RC drilling campaign during 2010, all the blank samples analysed are under one upper limit but one of the samples present which a value above one upper limit. This sample presents a grade of 0.032 ppm Au.

6.8.7 CONCLUSIONS OF QAQC STUDY

• CRM Standards

The review of external standard values plotted on control charts show results fall within acceptable limits, indicating analysis is reasonably accurate for Au, however, without the assay certificates available at this time it is impossible to confirm the standards used are correct. Therefore some caution is needed when interpreting these results.

• Duplicates

2010 RC drilling pulp duplicates show good precision. 2010-2011 diamond drilling 2010-2011 pulp duplicates also present an acceptable level of precision. Both results indicate that the precision of the analytical lab (Stewart Kyrgyzstan) was better for RC samples than for diamond drilling samples. RC drilling 2010 in-house lab duplicates have a lower precision and diamond drilling 2010-2011 present an acceptable precision result. Again, the results indicate that the precision of the analytical lab (Stewart Kyrgyzstan) was better for RC samples than for diamond drilling samples. Diamond drilling sampling methodology should be reviewed, to consider that no errors are committed during sampling and preparation process.

• Blank Samples In diamond drilling and RC all the blank samples are inside the acceptable limit, although in RC type of sample one sample is above one tolerance limit. The presence of this outlier could correspond with a transcription error, so it is recommended to check that all the data was type correctly.

6.8.8 RECOMMENDATIONS

Blank, duplicate and standard samples indicate that the analysis laboratory procedures meet with acceptable and standard procedures. Diamond drilling 2010 presents a good accuracy and an acceptable precision. RC drilling 2010 presents a good accuracy and but a very low precision. This result indicates a problem in the sampling process, previous to the analysis in the laboratory. A revision to the sampling process should be done. The grab samples taken in the exploration campaigns previous to 2010 only test for precision, and the result is that they present low precision. This result is quite common for grab samples, which sampling procedure sometimes doesn’t follow strictly the standard procedures. There are no tests for assay accuracy. Due to the lack of a proper QAQC procedures in the exploration campaigns prior to 2010 it is recommended Alhambra undertake a program of twinned drillholes and trenching, to verify the samples taken in the previous campaigns are reliable for use in estimation. It is also recommended Alhambra implement field duplicate sample collection and analysis as routine.

6.9 SHIROTNAIA - MINERAL PROCESSING AND METALLURGICAL TESTING

In 2007, a report of a study of heap leaching of gold from a sample of the oxide mineralisation of Shirotnaia was produced but is not available in English (Bolotova, 2007). The following text has been edited by ACA Howe from an English abstract of this report provided by Plyushchev (email of March 28 2011). In December 2006, Kazmechanobr received metallurgical sample number ShLT-1 from Shirotnaia. The sample of oxide gold mineralisation from exploration trenches 20/3, 24 and 28/1 has an average grade of 1.52 g/t Au. Considering the gold grade, chemical and mineralogical composition, the sample is representative of the oxide gold ore from the upper part of the oxide zone of Shirotnaia. Precise details of the sample location, size and representativeness are not presently available to ACA Howe. Based on mineralogical studies and semi-quantitative X-ray fluorescence spectroscopy and chemical analysis, the sample is composed of, in decreasing order of abundance, quartz 40 - 41% , clays 27%, mica 9 -10%, kaolinite 9%, gypsum 5%, iron hydroxides 4%, feldspar 3 - 4%, calcite 1%, halite 1%, haematite 0.5%, jarosite 0.1%, pyrite 0.1% and traces of gold, copper minerals, chlorite, zircon, etc. Gold is finely dispersed and after sample grinding occurs as free grains of 0.005-0.01 mm. In intergrowths with other minerals, gold occurs as fine films of 0.003 x 0.02 mm on peripheral parts of the grains. It is possible that before grinding all gold was present as inclusions in quartz. In a polished section, 2 or 3 grains of pure gold were observed. Possible electrum is rare, represented by free grains of 0.014 - 0.02 mm. One 0.03 mm grain of possible native silver was seen. Sulphide minerals include pyrite, chalcopyrite and covellite with grain sizes of 0.01- 0.05 mm. Fire assays of four sub-samples averaged 1.99 g/t Au (range 1.82 to 2.20) and 3.70 g/t Ag (range 0 to 4.40). Chemical analysis produced the following results in decreasing order of abundance: SiO2 58.40%, Al2O3 12.58%, Fe 3.02%, CaO 2.60%, MgO 1.50%, S total 0.92%, As 0.12%, Pb 0.035%, S sulphide 0.03%, Zn 0.01%, Sb <0.01%, Cu 0.006%, Ni 0.001%, Co <0.001%. Analysis by SEA produced the following results in decreasing order of abundance: Pb 0.1%, As 0.1%, Ti 0.05%, Ag ~ 0.01%, Zn 0.01%, Sb 0.007%, Mn 0.005%, Zr 0.005%, Ni 0.003%, Cu 0.002%, Mo 0.001%, Ga 0.0005%, Cr 0.0003%. Gold assay of screened fractions of an 8 kg sub-sample produced the results presented in Table 9 below.

In general, it was concluded that gold in the oxide responds well to cyanidation. Adsorption kinetics are quite high with about 80% of the gold recovered in 4 hours. The sample material contains some components with natural adsorption capacity. Agglomeration tests Percolation tests of untreated and agglomerated material were conducted using the technique of Kappes, Cassiday & Associates.


56

Hydrodynamic characteristics were studied in columns with 97 mm diameter and 480 mm height. Columns were filled with 4 kg untreated ore of minus 40 mm size and the same quantity of material was agglomerated using various regimes. The material was then soaked in water for 2 hours and the degree of settling and maximum percolation speeds were determined. The results of the percolation test of the original grain size material without agglomeration are given in Table 12 below.

Maximum percolation speed, l/m2/h 0 Moistening of the material took place very slowly, in about 24 hours. The solution did not percolate the 320 mm layer of wet material despite the fact that the water column above the material was at least 150 mm. Agglomeration was carried out in a laboratory barrel granulator with the addition of binding cement. Table 13 below shows the results of percolation tests of agglomerated material.

Column Cyanidation Test One column leach test was carried out using original grain size material. Another column leach test was carried out using material agglomerated with 17 kg/t binding cement. The pellets were then kept uncovered in a room for 72 hours. The leaching column was 2.40 m high and 0.25 m in diameter. The adsorption column dimensions were 285 mm and 80 mm respectively. Moistening solution was poured from above at the speed of 10-15 l/m2/h. Fresh ion exchange resin AM-2B was used as an adsorbent. Table 14 below shows the initial parameters of the column leach test.

After the conclusion of water washing of the column leach tails, tests were carried out to determine the cavities in the columns and the maximum flow velocity through the mineral layer. The results are shown in Table 20 below.

The water content of tails was 22.8%. Considering the results of column tests, water demand for the agglomeration and heap leach process was determined as shown in Table 21 below.

Based on the column leach test results, a metal balance was prepared as presented in Table 25 below.

Parameters Values Au Ag Gold recovery on resin, g/t 1.976 3.077 Gold recovery on water washing, g/t 0.012 - Gold grade in the column leach tails, g/t 0.24 0.05 Calculated gold grade in the original material, g/t 2.228 3.127 Gold recovery on resin, % 88.69 98.40 Gold recovery considering washing solutions, % 89.23 -


61

The results were used to calculate the expected industrial scale gold recovery. The following coefficients were used for the calculation:

0.9782 (97.82%) – Gold recovery on desorption and electrolysis; 0.9985 (99.85%) – Gold recovery at calcination and fusing of the cathode precipitate for doré; 0.875 – Coefficient of transition from column tests to industrial exploitation.

In this case the expected industrial scale gold recovery for the oxides of the Shirotnaia zone will amount to: 88.69 х 0.9782 х 0.9985 х 0.875 = 75.80%. Based on the gold leaching study using the column test results of metallurgical sample ShLT-1 from Shirotnaia oxide gold mineralisation from exploration trenches 20/3, 24 and 28/1, the following conclusions were made:

• The expected industrial scale gold recovery from agglomerated ore of natural grain size from the Shirotnaia zone will be 75.8% at original grade of 2.228 g/t;

• High speed kinetics of gold and silver leaching was demonstrated; percolated solution during the column test amounted to 1.824 m3/t;

• The consumption of reagents for leaching gold and silver from agglomerated ore was: NaCN – 0.593 kg/t, alkali – 0.285 kg/t;

• Washing solutions needed for the full rinsing of cyanide and alkali from the mineral would be 0.421 m3/t.

6.10 MCS NOVEMBER 2011-FEBRUARY 2012 MINERAL RESOURCE ESTIMATES

Following positive results from drilling and in-house geological modelling work, the decision was taken to undertake block model estimations for the Shirotnaia in-situ Au mineralised zones to meet with NI 43-101 and JORC reporting requirements.

The following sections describe the process and decision making employed for the November 2011 – February 2012 resource estimations.

6.10.1 SOFTWARE USED

The Shirotnaia resource estimates were prepared using MICROMINE version 2011 3D modelling software and Microsoft Excel 2007.

6.10.2 INPUT DATA SUMMARY

Micromine Consulting Services were provided with Shirotnaia zones drill and trench data in Microsoft Excel and Micromine file formats. Existing historical interpretations as polygons, wireframes and digital terrain models were provided in MICROMINE string, wireframe and .DXF format.

Raw data used in interpretation and modelling consists of data from Alhambra’s recent and 2007 diamond drilling and RC drilling, trench and RAB sampling exploration work undertaken by Alhambra and previous explorers.

Raw data used as input to estimation consists of 2007 DDH drill data, recent 2010-2011 diamond, RC drill data, verified 2007-2010 RAB data and verified 2005 trench data.


62

It is Micromine’s and ACA Howe’s opinion that available input data is suitable for use as part of a NI 43-101 compliant and reportable resource estimations.

A summary of input sample type for the Shirotnaia deposit models is presented in Table 26 below.

6.10.3 INPUT DATA

Data selected for use in the February 2012 block model estimations is contained in Micromine drillhole databases. Each drillhole database comprises collar, lithology, survey and assay data files. Each trench drillhole database comprises collar, survey and assay files.

Input data file listing is provided in Appendix 2 and applicable data files and wireframes are provided in the database which accompanies this report.

6.10.4 DATA VALIDATION

Drill hole collar, assay, survey and lithology data were processed as MICROMINE .dat files.

Data validation cross referencing collar, assay and litho (geology) files was performed in MICROMINE to confirm drill hole depths, identify any inconsistent or missing sample/logging intervals and survey data.

Channel collar, assay and survey were also processed as MICROMINE .dat files and validation performed to confirm hole depths between files, inconsistent or missing sample intervals and surveys.

No fatal errors were detected during computerised and visual data validation.

Data validation tables are presented in Appendix 2.

6.10.5 DESCRIPTIVE AND CLASSICAL STATISTICS

One of the most important parts of resource estimation is the study of the database, as its distribution has a fundamental influence in the estimation process. For the present study there have been taken into account the samples from the drilling programs, and the samples from the trench sampling program. In total, 15,758 samples have been studied for the Shirotnaia in-situ zones. The elements studied here are Au, those elements which were used to create the geological modelling and in estimation.

A summary of the unrestricted raw Au data basic parameters is presented in Table 27 below.

6.10.6 GOLD DISTRIBUTION

Au datasets for the deposit zone shows a strongly positive skewed distribution, with a great number of samples with low to very low grade, and few samples with high grade. Au does not follow a Gaussian Bell shape distribution. For estimation purposes each database’ distribution should present a Gaussian Bell shape (as would be in a ‘perfect’ distributed database). In order to conduct a study and statistical interpretation of the dataset, and trying to achieve the Gaussian Bell shape, it was necessary to plot element histograms using log-normal transformation. This is very common practice for gold deposit statistical analysis and estimation. Distribution graphs for the raw Au data for the Shirotnaia deposit zone are presented in Figures 34 to 36 below.

Figure 35: Log normal cumulative frequency curve for Shirotnaia raw Au dataset

Figure 36: Log normal probability plot for Shirotnaia raw Au dataset From the distribution tables above it can be seen that the log-normal distribution better represents a Gaussian Bell shape, although not perfect. This suggests that within the datasets there are different grade populations. For estimation purposes the different grade populations (in each element) need to be separated as best possible for reliable robust interpolations. A first approximation for getting the dataset divided into different populations is achieved through domain interpretation and modelling.

6.10.7 NATURAL CUT OFF

Each element’s dataset was carefully studied looking for the existence of a natural boundaries ‘cut offs’ between grade populations. This natural cut off would indicate the natural limit in the dataset between ‘mineralised’ samples and ‘non-mineralised’ samples.

Log Histograms and distribution tables generated for unrestricted data show grades to have a number of populations. From the log normal histograms it is observed that there is not a clear limit between the mineralised and the non-mineralised samples. Following careful review and interpretation limits were recognised where a natural cut off could be implied:

• In situ mineralisation = 0.18g/t Au

This grade value is considered as a natural boundary to mineralisation used for mineralised domain modelling of the deposit.

In addition to statistical support of natural grade boundaries, consideration was given to the deposit types being modelled, typical mining widths, anticipated mining methods and overall grade in selecting appropriate cut off values.

6.10.8 DOMAIN INTERPRETATION AND MODELLING

Domain interpretation was completed from cross section and plan displays in Micromine software. Interpretation of lode orientations done using information from discussions with Alhambra and ACA Howe personnel on geological and deposit models, review of literature, apparent continuity and correlation displayed by exploration data and also guided by existing wireframe 3D solid models of mineralisation supplied to MCS.

The interpreted profiles represent a 3 dimensional polygonal display of the current geological and exploration model, based on the recent drill and channel data for the zones, application of knowledge from mapped and inferred structural architectures.

The boundaries to mineralised zone digitised in cross section were interpreted using best practice industry standard techniques, snapping to drillhole assay intervals, and utilising lithology where applicable to improve accuracy of location of mineralised zone in 3 dimensions, and to reduce the inclusion of waste within the mineralised wireframes.

Grade domain modelling was completed for Au, with minimum width of approximately 1 m. Where appropriate, geology was used in combination with grade values to assist zone interpretation.

The following 13 Au grade domain models were generated across the 3 recognised deposit zones North, Central and South:

• North W1 • North W2 • North E1 • North E2 • North E3 • Central 1 • Central 2 • Central 3 • Central 4 • Central 5 • South W


66

• South E1 • South E2

Other criteria for the grade domain models are:

• Where constrained, lode mineralisation is extended half the distance between drillhole and trench samples, along both strike and dip direction.

• Where unconstrained, zones were extrapolated approximately 30 to 50 m along strike and approximately 30 to 50 m in the dip direction from sample control points depending upon grade, thickness and confidence in extrapolation of the model.

• Zones were extended approximately 1 m in a thickness direction where unconstrained, i.e. where drillholes and/or channels started or finished in mineralisation.

The types, number and characteristics of the models will be subject to change as new data becomes available and revisions of the geological model take place.

Once completed wireframes were validated both by visual examination and computer validated by use of the wireframe validation tools in Micromine.

Micromine wireframe validation process checks for open solids and any intersection triangles and strings which may cause problems in volume and tonnage calculations.

Each mineralised domain wireframe was checked and deemed valid.

6.10.10 TOP CUTS

Top cut analysis was performed on mineralised domain raw data for Au prior to block model estimation. Top cut analysis is undertaken to assess the influence extreme grade outliers has on the sample population of each domain. Whilst extreme grades are real, their influence in interpolation may overstate the block grades in some parts of the deposits. Micromine distribution graphs and ranked assay data were prepared and analysed to examine the domain samples and effects of a range of top-cuts applied to raw data and the effect these have on the co-efficient of variation (COV) and loss of data from the domain.

For the Au element studied via classical statistics, domain histograms and domain statistics indicate reasonably well distributed log normal data and coefficient of variation close to 1. A number of mineralised domains display minor amount of unusually high grade outliers which could affect the grade estimation.

Following statistical analysis of domain input Au sample data, top cuts of 10g/t Au were applied to the North E1 oxide, North E1 primary and Central 3 primary zones. Top cuts of 5g/t were applied to Central 3 oxide, Central 4 transitional and South E1 oxide zones. A top cut of 15g/t Au was applied to North E2 primary zone. All other domains remained uncut.

Top cut analysis graphs are presented in Appendix 3.

6.10.11 COMPOSITES

Prior to estimation, samples within the mineralised wireframes contained in the database assay files were composited to a standard length for geostatistical analysis and interpolation. The decision about composite length was determined by considering the histogram for raw sample intervals and selecting the dominant length.

By considering the histograms of sample intervals (Figure 39) the average sample length of 1 m was taken to be the composite length. A composite assay file was created for samples within the different domains wireframes to be used in block model interpolation.

6.10.12.2 VARIOGRAPHY

MCS conducted investigations into the production of meaningful semivariograms for use in a linear geostatistical interpolation method (ordinary kriged) however, due to the few samples available per domain, it was impossible to produce structured semi-variograms (it is commonly necessary to have a dataset of at least thousands of sample pairs per domain to undertake a variography study).

Therefore, MCS has not produced any variography study for grade interpolation, and used a non-geostatistical linear grade interpolation methodology. The interpolation method selected was Inverse Distance Weighting (IDW).

6.10.13 MCS NOVEMBER 2011 - FEBRUARY 2012 IDW BLOCK MODEL ESTIMATION

6.10.13.1 EMPTY CELL BLOCK MODEL

Domain restricted empty cell block models were created for each Shirotnaia deposit zone using definitions which cover the extent of mineralised domains.

Based on the geological model, exploration grid, search ellipsoid ranges, composite sizes and mining method, the data used in the estimate was block modelled with a block size of 10 m x 10 m x 10 m for the in-situ mineralisation and sub-blocking to 2 m x 2 m x 2 m was performed to achieve accuracy along domain wireframe boundaries.

This block size was chosen after considering the geological model, exploration grid, search ellipsoid ranges, composite size, SMU and potential future mining methods.

6.10.13.2 GRADE INTERPOLATION

Prior to grade interpolation, domains were checked for missing intervals. Resource estimation best practice dictates missing sample intervals are assigned a value of zero for grade interpolation. For the Shirotnaia mineralised domain models, missing intervals were detected and replaced with zero grades in domain North E1 (1 missing interval), North E2 (4 missing intervals), South W (52 missing intervals for hole with assays pending). Mineral grade was interpolated into the block models on a zone and element domain basis.

For interpolation both the block model and composite assay file was flagged by the mineral and zone domains and blocks within these domains assigned an interpolated grade (i.e. wireframe restricted or closed interpolation).


73

Metal grade interpolation was then undertaken using the input composite assay files for all areas which contained composite length drill and channel data.

Top cuts were applied to the input data according to statistical analysis performed and described in section 6.11.10.

For each domain, the parent block Inverse Distance Weighted interpolation technique was used and interpolation performed at different search radii, until all blocks within each domain had received an interpolated grade. The search distances were determined by means of the evaluation of drill/trench spacing (input sample spacing), and orientations through study of geological models and domain geometries.

Inverse distance weighting (IDW³) method of interpolation was used, which is a non-geostatistical (classical) method of grade interpolation. In this method, each input sample is weighted according to some power of the inverse distance from the block to be estimated. Interpolation weights are only applied to samples found within the search neighbourhood. There are no strict rules for choosing a power; for gold a value of two or three is often used, with three most common. For iron, a power of two may be appropriate. The lower the power, the more the grades are smoothed, to the point where using a low power will produce a result which deviates only slightly from the global mean of the data. On the other hand, higher powers will produce a result that approaches a nearest-neighbour interpolation, with the sample nearest the block contributing almost all of the weight.

A power of 3 was chosen for this interpolation given the deposit, grades and commodity type.

Search ellipsoid range (extent) parameters were based upon model geometries and sample density.

Due to the extreme low number of samples and narrow nature of the transitional zone, samples for the primary and transitional zones were combined for interpolation to inform the two zones.

The transitional and primary material zones split for the application of bulk density values and reporting purposes.

Table 30 below summarises the search ellipsoid parameters used for each Shirotnaia mineralised zone.

The first search radii for interpolation were selected to be equal to two thirds of the range in the strike, dip and across dip directions of the search ellipsoid. Model blocks that did not receive a grade estimate from the first interpolation run were used in the next interpolation run, equal to the full ranges in all directions. Subsequent search radii were incremented by multiples of the initial ranges in corresponding directions.

When model cells were estimated using radii not exceeding the full ranges (i.e. two thirds and equal to the ranges), a restriction of at least three samples from at least two drill holes was applied to increase the reliability of the estimates.

Detailed definition of the interpolation parameters is contained in Table 31 below.

6.10.15 RESOURCE CLASSIFICATION

Classification methodology, or assigning a level of confidence to mineral resources at Shirotnaia, has been undertaken in adherence to the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC Code, 2004 edition) and follows the Micromine Consulting Resource Modelling Standard Procedures (2010), and conforms to the CIM Mineral Resource and Mineral Reserve definitions referred to in National Instrument 43-101 and the Standards of Disclosure for Mineral Projects.

Classification of interpolated blocks is undertaken using the following criteria:

• Interpolation criteria based on sample density, search and interpolation parameters; • Assessment of the reliability of geological, sample, survey and bulk density data; • Robustness of the geological model; • Deposit type; • Drilling and sample density; • Understanding of grade continuity.

Through consideration of the above factors, MCS is of the opinion that a small portion of indicated blocks occur within the in situ mineralised domains, with inferred category an appropriate resource classification for the majority of in situ mineralisation at this time. There are a number of minor issues relating to data verification and QAQC which need to be addressed to increase confidence of input data, to increased resource class. Sample spacing and drillhole density within domains is wide and the total number of assays in a number of domains remains low, along with bulk density measurements for greater accuracy of tonnage calculations.

MCS is satisfied with the global validations for the Shirotnaia models.

6.10.16.2 LOCAL VALIDATION

Once modelling was completed, a series of sectional slices through the block models was undertaken to assess whether block grades honour the general sense of composite drill hole grades, that is to say that high grade blocks are location around high sample grades, and vice-versa.

A degree of smoothing is evident in block grade which is to be expected but on the whole block grades correlate well with sample grades. Local validation cross sections are presented in Appendix 4.

6.10.17 JANUARY 2012 IDW RESOURCE ESTIMATE REPORTING





For a single product the calculation is relatively straightforward. Resources are reported using an economic marginal cut off, determined by use of simple block revenue factor methodology and 2 year trailing average gold input price.

6.10.17.1 ECONOMIC CUT OFF DETERMINATION

Inputs for the calculation of block revenue for the Shirotnaia deposit are US$ value per ppm, and assumed metal % values in concentrate (product).

Inputs for oxide material are based upon actual mining cost data from Alhambra’s nearby Uzboy open pit operation, and estimated costs for transitional and primary material taken from recent PEA studies undertaken on the nearby Uzboy deposit. Key input data for cut off calculation include:

• Gold price US$1,401/oz; • Mining Method – open pit; • Oxide processing method – heap leach; • Transitional and primary processing method – gravity CIL; • Recovery – Oxide 70% Transitional/Primary 85%; • Oxide mining cost –US$1.7/t (in-situ); • Transitional and Primary mining costs – US$1.95/t; • Processing costs – US$3.85/t (oxide), US$6.47/t (transitional and primary).


Using the Au block grade, the above Au metal price and recovery, MCS estimated the revenue per mined block. For a mineralised block to be considered economic it must generate higher revenue than it costs to mine. For a block to be considered economic it must therefore generate greater than US$5.55/t and US$8.42/t of revenue, for in-situ oxide and transitional/primary material respectively. MCS used Micromine software to filter those blocks in the resource model with value greater than the calculated cost to mine values for economic cut-off grade determination and resource reporting.

At Shirotnaia, a total of 34.6 million tonnes of Inferred resources, grading at 0.58 g/t Au for 645,000 ounces Au have been identified. An additional 2.9 million tonnes of Indicated resources grading at 0.76 g/t Au have been identified for 71,000 ounces.

6.11 SHIROTNAIA - ADJACENT PROPERTIES

Adjacent properties are described above in the general section on this topic.

6.12 SHIROTNAIA - OTHER RELEVANT DATA AND INFORMATION

None.

6.13 SHIROTNAIA - INTERPRETATION AND CONCLUSIONS

Shirotnaia contains a large gold resource and significant gold potential at grades possibly amenable to heap leach gold production. NI 43-101 compliant computerised 3 dimensional resource estimations for the Shirotnaia gold project, Akmola Oblast, Kazakhstan were undertaken between November 2011 and February 2012. The study was undertaken by ACA Howe International Limited (ACA Howe) and Micromine Consulting Services UK (MCS). It is the opinion of ACA Howe and MCS that resources estimated as part of this study meet with CIM/JORC Inferred and Indicated category classifications based upon quality of input data, modelling and estimation methodology, interpolation criteria based on sample density, search and interpolation parameters, understanding and robustness of the geological model, drilling and sample density. The resource estimation has an effective date of January 9 2012 and represents a maiden NI 43-101 compliant resource estimation for the project. ACA Howe and MCS completed studies according to NI 43-101 and best practice guidelines. Resource modelling and estimations being completed using the industry accepted Micromine 2011, 3D modelling software package. Raw data used in interpretation and modelling consists of data from Alhambra’s recent and 2007 diamond drilling and RC drilling, trench and RAB sampling exploration work undertaken by Alhambra and previous explorers.

Raw data used as input to estimation consists of 2007 DDH drill data, recent 2010-2011 diamond, RC drill data, verified 2007-2010 RAB data and verified 2005 trench data.

The Shirotnaia project comprises in-situ structurally controlled oxide, transitional and primary mineralisation types. Mineralisation was modelled using natural cut-off grade of 0.18g/t Au for the mineralised zones. Several mineralised domains were modelled for resource estimation. The following 13 Au grade domain models were generated across the 3 recognised deposit zones North, Central and South:

• North W1 • North W2 • North E1 • North E2 • North E3 • Central 1


85

• Central 2 • Central 3 • Central 4 • Central 5 • South W • South E1 • South E2

Classification of resources is restricted to Indicated and Inferred, due to the following factors which introduce uncertainty:

o Limited number of valid drill holes and drill samples clustered in small areas; o The number of valid drillholes are widely spaced along domain extents; o Low number of valid samples per mineralised domain; o A low number or no bulk density data for a number of domains and sub-domains; o Lack of QAQC data, and quality control issues.

On working through the estimation process, it became clear that although the in situ deposit models are coherent and robust based upon an interpretation of combined historical and recent (valid) drilling, the domains require significant additional drill testing to increase valid input sample data numbers and sample density for both grade and bulk density determination, and improved resource block classification. Quality control sample data analysis and interpretation raised a number of issues with respect to assay precision and repeatability. This could be due to nugget effect or sampling error, and will require follow up investigation studies. Due to these reasons the restriction and selection of resource classification currently applicable to the deposit areas are deemed appropriate, particularly for in-situ domains. At Shirotnaia, a total of 34.6 million tonnes of Inferred resources, grading at 0.58 g/t Au for 645,000 ounces Au have been identified. An additional 2.9 million tonnes of Indicated resources grading at 0.76 g/t Au have been identified for 71,000 ounces.





For a single product the calculation is relatively straightforward. Resources are reported using an economic marginal cut off, determined by use of simple block revenue factor methodology and 2 year trailing average gold input price.

Inputs for oxide material are based upon actual mining cost data from Alhambra’s nearby Uzboy open pit operation, and estimated costs for transitional and primary material taken from recent PEA studies undertaken on the nearby Uzboy deposit. Key input data for cut off calculation include:

• Gold price US$1,401/oz; • Mining Method – open pit; • Oxide processing method – heap leach; • Transitional and primary processing method – gravity CIL; • Recovery – Oxide 70% Transitional/Primary 85%; • Oxide mining cost – US$1.7/t (in-situ); • Transitional and Primary mining costs – US$1.95/t; • Processing costs – US$3.85/t (oxide), US$6.47/t (transitional and primary).


Using the Au block grade, the above Au metal price and recovery, MCS estimated the revenue per mined block. For a mineralised block to be considered economic it must generate higher revenue than it costs to mine. For a block to be considered economic it must therefore generate greater than $5.55/t and $8.42/t of revenue, for in-situ oxide and transitional/primary material respectively. MCS used Micromine software to filter those blocks in the resource model with value greater than the calculated cost to mine values for economic cut-off grade determination and resource reporting.


At Shirotnaia, mineralisation occurs within three main east-northeast trending structural zones, namely North, Central and South. The in-situ gold mineralisation at Shirotnaia is hosted in a sequence of mostly andesitic volcanic and volcaniclastic rocks with rare sediment horizons. There is an oxidized zone to an average depth from surface of about 20 m and a transition zone about 16 m thick below that, underlain by primary gold mineralisation. In the North zone corridor, resources are defined within discreet steep northwest dipping structures in four sub-zones over a 2.0 km strike length, to maximum depth of approximately 200 mbs. Mineralised zones are open along strike and at depth, with evidence of continuation of mineralisation indicated by trench and shallow RAB drilling. Within the 2.0 km strike length, a 400 m section between northwest and northeast domains remains untested, offering significant potential for further immediate resources. In the Central zone, resources are defined within discreet moderate to steep northwest dipping structures over a 1.2 km strike length, to a maximum depth of approximately 200 mbs. Mineralisation


87

is open along strike and at depth, with evidence of continued mineralisation indicated from trenching and shallow RAB drilling. In the South zone, resources are defined within shallow northwest dipping structures in three sub-zones over a 1.1 km strike length to a maximum depth of approximately 150 mbs. Mineralisation remains open along strike and at depth. An untested area of 300 m strike length between west and east mineralised domains offers significant immediate resource potential.

6.14 SHIROTNAIA - RECOMMENDATIONS

Several issues and sensitivities have been highlighted as part of this study and are outlined below. These issues ultimately impact on the robustness and confidence of the geological and resource model and should be considered for improved assessment, estimation of higher classification of resources and mine planning.

• Data Collection

No geotechnical/geomechanical logging is taking place at drill site, and although core recoveries are reported to be very good overall, it is best practice to perform orientation marking, metre marking, recovery, RQD and fracture frequency logging, prior to transportation. Transportation of the core could result in the disintegration of less competent zones (which generally tend to be those of greatest interest).

The lack of drill core orientation is an issue. Much more information could and should be collected from drill core given the structural complexities that exist at the deposit. Greater accuracy with metre marking, RQD measurements, along with performing angle and orientation (alpha/beta) measurements of features relative to orientation line and core axis is essential in these deposit types. The importance of oriented drill core and measurement of controlling structures will become critical as exploration and work towards improved resource classification within the project continues.

Sampling is performed to a reasonable standard. However, due to the non-orientation of the drill core, inconsistencies are introduced into the system. Without orientation line control, the core will be sampled randomly along its axis, and may well introduce bias to the samples. Best practice is to sample along the core orientation line thus being consistent and selecting a sample perpendicular to the perceived strike of mineralisation and mineralised veins, etc.

The sampling methodology is considered good practise in this type of deposit and is suitable for gaining a detailed understanding of lithological host rocks and controls of mineralisation..

Bulk density date is lacking from a number of areas. A greater number of bulk density samples are required from all zones.

• Analyses

Sampling preparation methodology appears reasonable and satisfactory.

Sample dispatch routines, and dispatch record sheets which have been observed and considered consistent and of a satisfactory standard.

Sample security protocols were discussed with site personnel and demonstrated to MCS during the project site visit. These are considered entirely satisfactory.


88

Checks on accuracy of analytical process and equipment for DDH appear satisfactory, however duplicate analysis for RC and grab samples are seen to show low correlation and this requires follow up.

This is of concern with regard to nugget effect and/or the preparation of samples potential contamination and introduction of error at the sample preparation stage.

It is MCS’ opinion that although overall satisfactory quality control and assurance for the current dataset does raise some concerns and issues with regard to precision and accuracy of analysis. These issues should be investigated further as part of the ongoing QAQC process to enable improved confidence in updated resource estimations. Recommendations include:

• Use of field duplicates

• Verification twin drill holes and trenching

• Domain modelling

Geology and controls are reasonably well understood given the available data for the particular study area, and historical models. Better understanding can be gained by improved alteration and structural logging (oriented core), which will ultimately improve resource models and resource confidence.

• Metallurgical testwork

Further metallurgical test work is required to obtain representative values across all deposit areas and material types.

In addition MCS recommends the following work is undertaken to progress the deposit areas toward improved classified and reportable resource and reserve block model estimations.

• Further drill testing of current exploration solid models along strike and at depth • Detailed geological, structural and grade domain modelling of the new drilling areas and

development of exploration/deposit model and concepts in the current near surface exploration areas to assist further exploration and resource estimations

• Refined domain geostatistics to determine optimal natural grade boundaries • Domain statistics and variography to determine optimum exploration drill spacing • Further historical data import, modelling and verification by possible means of selected

channel and or drillhole re-sampling and analysis, twin drillhole verification, comparison of historical exploration data versus production data

• Follow up and resolve current data validation issues • Detailed review of literature and deposit model types • Audit of analytical laboratory and review of certification/accreditation • Review and/or updated metallurgical test work studies.

It is recommended both the historical and current database and the wireframe models be constantly updated and should always reflect the latest stage of the exploration so that changes or adjustments to any future exploration programs (planned drilling location), can be made immediately with best available data and interpretations.

98 Authors of the Report on Process QA/QC at the Dombraly and Shirotnaia Deposits of Sary-Arka licensed territory of Saga Creek Gold Company LLP visited the stated deposits for the purpose of inspection of conducted geological exploration works, their scope and quality. The deposits are explored on the basis of issued licences No.719ДД and No. 1029Д. The Dombraly and Shirotnaia gold deposits are located in North Kazakhstan Oblast of the Republic of Kazakhstan in the region with developed infrastructure. The major gold fields known here are Vassilkovskoe, Stepnyak, Aksu, Bestobe, Zhelombet, also there are uranium, tin, industrial diamonds, titanium and zircon deposits. Underexplored deposits of Bailyusty, Severnoe Bailyusty and Kimaly are located nearby the Dombraly and Shirotnaia deposits. The Dombraly deposit was discovered in 1966 and from 2002 it has been explored by Saga Creek Gold Company LLP. Geological-economic appraisal (together with Geos LLP) based on the results of estimation by alternatives of oxide-bearing gold ores was carried out in 2006. Feasibility study of evaluation conditions was approved by the State Reserves Committee of the Republic of Kazakhstan (the RoK SRC) (Minutes of Meeting No.496-06-K dated 21.03.2006). Obtained technical and economic indicators prove the possibility of cost-effective development of gold-sulphide ores together with technologic mineral formations by open-cut mining. Oxide reserve mining in solid of the open pit was considered to be economically impractical due to a high strip ratio and insufficient content of gold in oxide ore. However, with current prices on gold this position will be reconsidered. Total reserves in subsoil of oxide ores, re-cultivated mined rock in open pit and industrial dump of С2 category amounted to: ore – 4254.1 thous. tons, gold – 6478.8 kg, average gold content – 1.52 g/ton. Reserves of gold-sulphide ore to the depth of 300 m on С2 category amounted to: ore – 575.6 thous. tons, gold – 3119.6 kg, average gold content – 5.42 g/ton. Geological exploration works are still ongoing. The Shirotnaia deposit is located in Akkol region, 3 km north-east from Aksu settlement. Most of the deposit is located in stream-valley and is bridged over with recent sediments. Exploration works in 2002-2011 were carried out on the territory of the whole deposit by trenching, drilling core holes, RCC holes and air drilled holes. These works resulted in detecting of 2 thick zones of mineralization including the group of large ore bodies and lenses. On the south-west side, 520 m from the main body, there is a zone of a column-shaped mineralization with inclination 50-450 north-west. Exploration of main ore bodies was done by core holes to the depth of 120-140 m (18 holes). North-east flank with length of up to 2 km is the most prospective for discovering new ore bodies. Four bodies of ore mineralization with length of 1100 m and thickness of 5-40 m with average gold content of 0.8-1.1 g/ton were discovered as a result of exploration drilling works on this flank. As of 01.01.2010, according to the preliminary estimation, gold reserves in the area of oxidation on С2 category amounted to 3900 kg with average gold content of 1.2 g/t. In oxide ores on P2 category the gold amounted to 40,000 kg with average content of 1.2 g/t. The exploration works are still ongoing on the site. The results of analyses on the main part of holes samples for this year haven’t been obtained yet. The results of works are stated in corresponding reports and are done using Microsoft Excel, Word, MapInfo, Access, Corel Drаw. Interpretation of geological exploration data on the Dombraly and Shirotnaia deposits was carried out by Micromine program. The authors are thankful to the management and the chief specialists: John Komarnitski (Alhambra company) and Alexander Miroshnichenko, Yevgeniy Plyuschev, Stepan Trofimov (Saga Creek Gold company) for warm welcome and arranging details allowing visiting the Dombraly and Shirotnaia deposits on August 11-15, 2011, as well as seeing their infrastructure and collecting the required geological data. 1. Brief Geological Structure of the Contract Area The contract territory (Licences No.719ДД and No.1029Д) covers north-east part of Kokchetav-North-Tian-Shan Caledonian mosaic fold system. In the northern part of Kokchetav-North-Tian-Shan fold system there are four Caledonian structured formation megazones with almost north-south direction: Ishim-Karatau megazone (western), Kokchetav-Ulutau anticline megazone (eastern), Stepnyak-Zhaksykon syncline megazone (central), Yerementau-Boschekul anticline megazone (from the east). The contract territory is mostly located in the central and north parts of Stepnyak syncline. From the west and from the north, the part of Kokchetav block mass anticline is considered the part of the contract territory (Kokchetav and Shat anticline) and from the east – the western part of Ishkeolmes anticline is also considered the part of the contract territory.

Kokchetav block mass is divided by geologic and geophysical data into four structure blocks: Shatskiy, Zagradskiy, Borovskoi and Zerendinskiy. The Caledonian structures formed by the mid-Ordovician deposits of Stepnyak strata lay in the structures of ancient folded body of Kokchetav block mass with dramatically different tectonic layout. These mid-Ordovician deposits form rather small brachiform synclines. The largest ones have sub-lateral extension. Superposed folds made by glomerations and sand-rock of upper Ordovician also have the same characteristics. Stepnyak syncline is a complex late-Caledonian folded structure. It is formed by slightly metamorphized deposits of mainly middle and upper Ordovician. There are several syncline and anticline zones in the synclinorium. Hercynian structural level is represented by wide and flat geological basins laid over consolidated Stepnyak synclinorium and Ishkeolmess anticlinorium. Geological basins are formed by thick mass of the volcanic rocks of the Lower-Middle Devonian, the red beds of the Givetian-Frankish age, and by carbonic rock. 2. General Information on the Dombraly Deposit The Dombraly gold field is located within a sheet N-43-109-a. Geographical coordinates of the field center – N 52°55 ́and E 72°05 .́ The nearest railroad station “Aksu” is located in 70 km to the south from the field. The nearest settlements in the area of the deposit are Zolotaya Niva (15 km west), Projektor (20 km east) villages, Komsomolskiy settlement (42 km north-east), Valikhanova settlement (40 km west), population of which is mostly work on personal farms. All settlements are interconnected by country roads that are only suitable for vehicles at summer. The terrain of the deposit area is plain with highly compressed ridges, ranges, wide drainless hollows and lake degradations. Sea level is 220-325 m with local difference in elevation being 1-5 m, rarely 8-10 m. The area exposure is very poor. Segmental rock outbreaks of effusive rock are rare. The whole area of works is blocked by poorly consolidates sediments of the Quarternary age, thickness of which on the average does not exceed 10 meters. Hydrographic network of the area is underdeveloped and is represented by rare dried river channels and Kizdyn-Karassu and Karassu rivers. Rivers’ water schedule is of a seasonal nature and their activity depends on the spring thaw and periodic rains. During the summer the rivers look like the chain of narrow, shallow and isolated from each other pools. River beds are formed by clay loam, sand clay, clays and rarely by sand and gravel material. River valleys are meandering with insignificant slopes (0.001-0.002), smooth slopes, poorly defined terraces above flood-plain and flood-plains. River valleys are usually swamped. The climate of the region is extremely continental. The coldest months are January and February with average monthly temperatures varying from -17°, -20° up to – 35.4°. The highest average monthly temperatures (+18°, +22°) are in June-July and reach up to 35.3°. Average annual precipitation varies from 250 to 300 mm. Long-term average annual precipitation is 268 mm. Prevailing wind direction at summer is west and south-west; at winter – north-west, west and rarely north-east and east. The territory can be classified as sheep fescue/feather-grass steppe of the North Kazakhstan as per the nature of vegetation. Xerophilous narrow-leaved gramineous plants like feather grass, Stipa capillata and sheep fescue form a rather monotonous background. In low places carpet plants become denser, gramineous plants are replaced with miscellaneous herbs. Birch and aspen groves with bushes grow in swamped low lands.


101

Soil cover is represented by reddish brown and light-gray chestnut, loam and sandy loam soils with thin humus horizon (0.1-0.5 m). Fauna is defined by the peculiarities of the landscape. Mammals are mostly represented by rodents: prairie dogs, hamsters, field mice, marmots and such animals as hares, wolves and foxes. Large mammals (roedeers and roars) are rather rare. There are enormous numbers of mosquitoes, midges, horse-flies, gadflies, flies and mites. There are a lot of birds are well. Most of them are of passerine and sandpiper families.

View of the open pit from the low grade stockpile Electricity for a future mining processing plant will be supplied via LEP-35 kV (power line) constructed by the subsoil user from Zolotaya Niva village (15 km) to the deposit. Supply of drink and process water for the needs of processing facilities will be ensured in required volumes from the wells drilled on the territory of the deposit. Explored fields of industrial minerals are unknown in this area. Surroundings of the deposit to the radius of 20-25 km are prospective for exploring deposits of non-metal rock and industrial minerals

deposit required for arranging ore processing production by heap leaching method: waterproof clay sand and gravel mix. Large-scale geological exploration works in the area of Dombraly deposit were started in 1952 by searching party of the Kazzoloto trust of quartz-lode deposit of Severnoe gold field (Severnoe Bailyusty). Evaluation of this site was also conducted by this party in 1966-1968, and in 1969-1972 by Tselinograd Exploration Company of the Central Kazakhstan Territorial Geological Administration. During the exploration period oxide zone was explored by mine opening on surface (pit-holes, ditches, test pits, bell-pits) and by underground mining workings (shaft, roadways and crosscuts to it) on the horizon 30 m from the surface and down to 170 m by core holes. During exploration period, technological survey of oxide ores for developing a washing process layout was done. Reserves estimation was approved by the Territorial Reserves Committee of the Central Committee of Production Geological Association (Minutes of Meeting, No. 3-411, dated 27.02.81). Estimated reserves were assigned to the balance of Kazzoloto industrial complex, except the reserves of С2 category. In 1985-1988 the deposit was mined to the horizon of 60 m from the surface by Enbek prospector’s team of Kazzoloto Mining and Processing Complex. For the period of operation, 140 thousand tons of ore and 949 kg of gold with content of 6.96 g/t were extracted. In 2002-2005 geological exploration works at the Dombraly deposit were re-started by JV Saga Creek Gold Company LLP. The purpose of the works of this period was re-estimation of oxide ore reserves in pillars with account to the gold in the re-cultivated rock mass in the open pit for determining the opportunity for their processing by heap leaching technology. During the works on preliminary economic-geological evaluation it became clear that it was economically impractical to process all oxide ore reserves due to high overburden ratio and insufficient gold content in the oxide ores. Cost efficient development is possible only for some part of oxide ore reserves (by reducing the depth of final open pit). At that, the reserves of oxide ores for development will be decreased by 33.8%. Complete development of gold reserves in oxide zone is only possible by taking dump technogenic mineral formations to heap leaching processing. Reserves estimation in technogenic mineral formations was carried out in 2005. Geological exploration works on estimation of gold-sulphide ores were conducted together with re-estimation of the reserves of gold in oxide area. Volumes of the reserves as of 01.01.2008 of the Dombraly deposit are shown below:

Table 2.1 Estimation of oxide ores in situ and in technogenic formations of the Dombraly deposit was done on the basis of the results of geological exploration works carried out by the Dombraly Geological Exploration Crew of Tselinograd Exploration Company of TsKTGU in 1969-1972 and by JV Saga Creek Gold Company LLP in 2002-2005 on the basis of estimation conditions approved by the RoK State Reserved Committee (Minutes of Meeting, No.496-06-K, dated 21.03.2006). Estimation parameters accepted by the analogy to estimation conditions for the gold-sulphide ores of the Uzboy deposit (underground development method) were used for estimation of the gold-sulphide ore reserves. Chemical analyses were made at Kvartz Chemical Analytical Laboratory LLP and Tsentrgeolanalit CJSC. Technological survey was done by Kazmekhanobrom. Such works as: field survey, hydrogeological, engineering-geological works and environmental monitoring, were conducted by the Karagandy Branch of Azimut Company.

2.1 Geological Structure of the Dombraly Deposit The Dombraly II deposit is located in the Stepnyak synclinorium close to its connection to Ishkeolmess anticlinorium. It is referred to the central part of the Bailyust synclinal zone complicating the Stepnyak synclinorium with north-north-west trending in the area of the deposit. The total length of the structure is approximately 100 km with width of 11 km. The deposit is located within the Dombraly tectonic zone of north-north-west trending. Within this structure there are several gold ore occurences: to the north of the deposit - Kimaly gold polymetallic ore occurrence and small quartz-lode deposit of gold Severnoe Bailyusty, to the south – Bailyusty gold field and other gold ore occurrence. 2.1.1 Stratigraphy Igneous-sedimentary rocks of Maylisor, Mayatass (Bailyust) and Shat (Koksengirsor) series of upper Ordovician take part in forming the geological structure of the deposit. Maylisor series (upper-Caradoc Sub-stage – Ashgillian Stage). Diabase-spilite strata of Maylisor series forms the western wing of synclinal fold. It is formed by dark-green-gray spilites and diabases with interlayers of tuffs and tuffaceous sandstone. Diabases in form of thin dikes are found in the layer of spilites. Mayatass (Bailyust) series (upper-Caradoc Sub-stage – Ashgillian Stage). Deposits of these series form the core part of the Ordovician synclinorium. The horizon of ash-gray tuffaceous sandstones and silty rocks with lens of psammite and psammite-psephitic tuffs of average composition lies in the base of the series. It is separated from the overlying horizon by interlayer of basal conglomerates. Polymictic sandstones, silty rocks, argillites of gray, green and lilac color with interlayers of silicified and carbon-bearing silty rocks and lens of marmorized limestone are developed in the upper part of series cut. Shat (Koksengirsor) series (upper-Caradoc Sub-stage – Ashgillian Stage). Deposits of these series form core parts of small synclinal folds of sub-meridian and north-west trending. They are mostly represented by tuffs of andesitic composition interlaying with coarse-grained tuffaceous sandstone. Mesozoic Weathering Crusts. Weathering crusts developed throughout the whole territory of the site, they are concealed under the Cenozoic deposits. Areal and fractured-linear types of crust can be observed. Areal weathering crusts in section are characterized by subhorizontal occurrence of subzones. In the linear-fractured saprolites the subzones occur aslope matching the attitude of tectonic dislocations, on which they develop. As per the degree of changes in the section of a crust the following five are weathered (from top to bottom): Structureless clayish weathered crust composed from reddish-yellow, light-gray-green, light-brown, grayish- and pinkish-red clays, sometimes, with inclusion of ferrous nodules. Indistinct relics of structures and textures of parent rock can be rarely detected in the lower part. Possibly, it corresponds to the zone of colored kaolinites by its composition. Structured clayish, loamy, arenaceuos weathered crust (corresponds to the upper part of intermediate weathering) is represented by clays, and with high content of quartz in parent rock it is represented by clay loam and sand clay with usually distinct relict structure and texture of parent rock. Thickness is from 4 to 9 m, in the areas of tectonic jointing it increased up to 18 m. Rubble-clayish weathered crust (the volume of break stone of weathered parent rock being less than 50%). The most of the rock volume is clays, clay loam and sand clay. It corresponds to the lower part of intermediate weathering area. Thickness is from 1.5 to 8-12 m, in the areas of jointing – up to 17 m.


105

Rubble-clayish weathered crust (the volume of break stone of weathered parent rock being more than 50%), corresponds to the upper part of rock breaking area. Thickness is from 0.2 to 13 m. Intensively weathered-fractured rocks corresponding to the lower part of rock breaking area. Thickness is from 6-10 m to 19-26 m. Total thickness of weathered crusts throughout the territory varies from 21 to 120 m. Selective concentration of gold in any subzone of weathered crust hasn’t been detected. The previous exploration works detected non-availability of a significant gold migration in the process of crust formation. There was only coarsening of gold with insignificant concentration of oxide ores comparing to the initial condition. Concentration did not exceed 5-10% and occurred by partial removal of parent rock material during crust formation. Cenozoic Group Deposits of the Cenozoic group are represented by eluvial formations covered by clayish deposits and topsoil. Eluvial formations developed on the Ordovician are detected everywhere, lithologically represented by sand clay, clay loam, clays, rubbly rock and argillite. They were uncovered on the depth of 0.20-2.00 m, uncovered thickness reaches 118.50 m (hole 19). Amongst clayish rock the most frequent is clay loams, both – in plan view and by depth. They are uncovered on the depth of 0.2-11.20 m, maximum uncovered thickness reaches 41.60 m (hole 19). Sand clays and clays are distributed sporadically. Clayish soils are multicolored, moist, hard, solid, ferruginous; in the upper part of geological section they are with fractures filled with quarternary clay loams, often with semi-rock and rock chippings of up to 30-40%. Rubbly rock with clay loam filling reaching up to 30% is of dark-violet color, was uncovered by hole 20 at the depth of 37 m, uncovered depth – 7.5 m. Argillites are dark-violet, gray with bluish shade, crumbling, rather frail, with low ferruginization and interlayers of clay loam in the beginning of the interval. Uncovered by holes 19 and 20 at the depth of 42.6, 44.5 m. Maximal uncovered thickness is 47.8 m (hole 19). Topsoil is almost everywhere. Its thickness is 0.15-0.30 m. 2.1.2 Subvolcanic Magmatism Subvolcanic intrusions of the upper Ordovician. Intrusions are represented by several separate bodies of andesite porphyrites, dolerite and dikes. Subvolcanic bodies of andesite are logged on the south flank of the ore field. In plan view they have lenticular shape. Their size on long axis is 800-900 m, and on short – 200-400 m. They are characterized by greenish-brown color, porphyric structure and small/medium-grained ground mass. Porphyric buildups are numerous and large (up to 5-10 mm), they are represented by plagioclase and hornblende. Subvolcanic body of dolerites is located 1 km north-east from the deposit. It has lenticular shape and sizes of 480x180 m.


106

Dikes of diabases are localized within the ore area of the deposit and are related to the tectonic areas of sub-meridian trend. They are not detected often. These dikes are characterize by insignificant thickness (from 0.5 to 5-10 m), length (first dozen of meters and are not affected by hydrothermal metasomatic changes. 2.1.3 Tectonics Synclinal limb containing the deposit is tectonized by two systems of fractures. Thrust fault of northeast trending is the basic disjunctive structure and with a dip it moves east, southeast under 60-70 degrees. The thickness of the brecciation zone on the south flank of the deposit varies within 3-6 m. The group of sub-parallel crushed zones of north-west trending is ore-bearing. Dip of these zones varies within 45-65 degrees to the east. Crushed zones were detected rather clearly by south and north trending by mine opening, holes and geophysical methods. Both fault systems are accompanied by numerous cleavages and shear cracks filled with quartz. The net of echelon small cracks determining the stockwork structure of ore body formed in the areas of fault junctions. 2.2 Ore Body Characteristics The main ore body and 7 smaller lenses are detected within the area of the Dombraly field oxide zone with the cutoff grade of gold being 0.3 g/t. The main ore body includes 73.6% of the total gold reserves of the deposit, it is explored by drill holes and underground mining and outlined on the surface alone the strike. It is not outlined by the slope, explored to the depth of 300 m. To the depth of 60 m it was explored by open mining in 1985-88. In view plan, the ore body mostly have irregular lens form stretched to sub-meridian direction with sizes on long axis up to 300-500 m, on short axis - 50-60 m. From the side of a hanging layer, lenses 1, 2 and 3 being its apophysis are connected to the ore body. From the north, the ore body sharply wedges out between profiles 32 and 36. It is possible that this sharp wedge of the ore is associated with dislocation of ore body by fault plane. In section, the ore body has asymmetrical lens form and at the bottom it is split into several branches. In the axial part of the ore body, there are the series of quartz veins and zones of stockwork silicification that on the flanks of ore body also split. The dip of the ore body is eastern, rather flat (60-45 degrees), decline is to the north under 20 degrees in the oxide zone and 45 degrees on the lower horizons. Earlier explored ore bodies 1, apophysis and 2 with cutoff gold grade of 3.0 g/t are localized within the outline of the main ore body and are controlled by the zones of stockwork silicification. The Parameters of the main ore bodies of the Dombraly deposit with cut-off grades of gold 0.3 g/t are shown in Table 2.2.

The low grade stockpile is located 170 km south of the open pit on the southeast extension of gold ore mineralization zone with reserves of 1.7 million tons. The low grade stockpile is not registered in the state records. The industrial value of TMF was determined by the geological exploration works carried out by Saga Creek Gold Company in 2002-2006. The only commercial element in the low grade stockpile is gold. The area of the low grade stockpile base is 123095 m2. The volume of the low grade stockpile is 1049.4 thousand m3. Re-cultivating mined rock fills the south part of the open pit. It has double deck structure. The south part of the open pit from profile 16 is filled completely to altitude of 218.6 m. The north part of the open pit is filled partially due to the naturally occurring sloughing of the open pit sides. With regard to the TMF reserves of the open pit it is rather small (1.06 million tons). The volume of the re-cultivating mine rock is 612.9 thousand m3. 2.3 The Group of the Deposit Complexity The deposit is classified as the third group of geological structure complexity according to The Classification of Reserves and Possible Resources of Solid Mineral Deposits (the RoK State Reserves Committee, 2001). The low grade stockpile of the deposit is classified as a second group (average complexity) on the complexity of exploration. Methodical recommendations on analysis and evaluation of TMF (1995) suggest air-drilled holes for the category С1 50 х 100 m. This low grade stockpile was explored by air-drilled holes 40-60 x 50 taking into account high value of gold grade variation (224.1%). 2.4 Estimation of Forecast Resources The increase of reserve can be achieved on the flanks and deep horizons of the deposit. Currently, this area of southeast flank is taken for the dump and it is impossible to carry out geological exploration works here. The forecast resources of Р1 category of the main ore body were estimated by the geological blocks. Outline of the Р1 category resources fixed to the C2 category reserves block. The depth of resources evaluation was limited to 500 m from the surface. The average content of gold and average horizontal thickness were determined on the basis of the data of sampling drillholes No.401, 402, 403. For the lens of ore 4 forecasted resources of Р1 category were estimated to the depth of 300 m. Determined on the basis of the data of sampling drillhole No.23. Forecast resources for Р1 category are 3072.6 kg with average content of 6.02 g/t. 2.5 Geological Exploration Work Methods

2.5.1. Survey Works Survey of the Dombraly deposit was conducted to the scale of 1:1000. During this survey all old and new geological exploration working were re-connected. Survey works were conducted by the specialized division of the Karagandy Branch of Azimut Enegry Services JSC. Division of the basic geodetic network to areas was done using nearest earlier set 3, 4 order state triangulation points and the state leveling network. The total of 4 points were surveyed and used further as the base ones for the next work stages. Transfer of coordinates from WGS-84 system to a nominal coordinate system was done with Trimble Geomatic Office, Geocalc software. Field survey works were done with equipment of GPS Trimble4600 in PP-Kinematic mode. GPS receiver Topcon GP-R1D was used as a base station. Processing of field survey data was done with GPSurvey and Trimble Geomatic Office software with conversion to the nominal system of coordinates and to the Baltic Height System. Futher, this set of pickets was loaded to CREDO_TER program for creation of the digital surface model. In the zones closed from satellites electronic tachometer Topcon GTS-302 with field terminal FS-5 was used. Tacheometric survey processing was done in CREDO_DAT program. Topographical drawings were prepared in CREDO_TER program with further export to AutoCAD and MapInfor. Horizontals were drawn with the interval of 0.5 m. 2.5.2 Stages of the Deposit Exploration The first stage of exploration and evaluation of oxide zone reserves of the Dombraly deposit was done in 1969-1972. The program of works included topographic survey, preparation of regional and local maps, trenching, delving, mines and underground workings in horizons, core drilling and technological sampling. Deposit exploration was done from the surface with ditches and bell pits every 12-25 m, on the horizon of 30 m – by mine roadways and crossways from them every 20-25 m and holes by 20x40 and 40x60-80 m grid down to 100-180 m. The volumes of geological exploration works for this period are provided in the tables below: Table 2.3 The volumes of geological exploration works for the period from 1969 to 1972 Type of works Meas.unit 1969-1972 Prospecting and exploration drilling

Reserves of the deposit oxide zone were evaluated to the depth of 170 m from the surface. Two ore bodies were detected in the oxide zone. Reserves of the deposit oxide ores were approved by the Territorial Reserves Committee of the Central Committee of the Production Geological Association (Minutes of Meeting No.3-411 dated 27.02.81). The following reserves were approved with the cutoff grade of gold being 3.0 g/t: for С1 category –87793 tons of ore, 949 kg of gold with average content being 10.8 g/t of gold. In 2002-2005 geological exploration works at the deposit were conducted by Caga Creek Gold Company. The main purpose of geological exploration was clarification of the lower border of the oxide zone, detection and evaluation of gold-sulphide mineralization, exploration of technogenic mineral formations of the low grade stockpile and re-estimation of the oxide zone for detecting an opportunity for processing the remaining oxide ores by heap leaching method. Moreover, additional exploration of poorly studied oxide zone flanks was carried out. Digital database including all old and new data for geological-economical evaluation of the deposit oxide zone was created. Core drilling with Longyear bullet was applied. There were 10 holes drilled with total volume of 2394 m. Technogenic mineral formations were explored by air drilling and ditches. Scope of works for 2002-2005 is shown in table 2.5.

mine rock in the outline of the open pit and in technogenic formations are: ore – 3797 thous.tons, gold – 5629 kg, average gold content – 1.48 g/t. In 2007-2011 the deposit was explored again by drilling exploration holes and trenching. 2.5.3. Methods of the Deposit Study In 1969-1972 the oxide zone was explored by trenches, pits with cuttings, mine with the range of underground workings. All workings were planned in exploration lines oriented transversely to potential length of the ore body. From the mine with section of 9 m2, on the horizon of 30 m, the ore drive with section of 4 m2 was made on the length of the main ore body in the south and north direction with total length of 220 m. From the ore drive transversely to ore bodies seven crossways were made of 4 m2 in section with the length from 25 to 50 m for outlining ore bodies I and II every 25-50 m. Trenches were planned on the area with thin layer of overburdens (0.5-3 m) laying on a clay-like weathered crust of the Paleozoic ores. The depth of the trenches is 3.2-3.5 m with the width of 1 m. The distance between the trenches is 15-20 m and it was determined on the basis of the instruction requirements for exploration works on the deposits of this type.

Photo 3. Drilling hole on the Dombraly site Prospect drilling was done on profiles through 40-60 m under 80 degrees angle and magnetic azimuth of 260 degrees transversely to the strike of ore-bearing structures and ore zones and downward by 40-60-80 meters. Drilling of core holes was done to the diameter of 127 mm to the depth of 5-6 m and further drilling was done to the diameter of 108 mm to the depth of 50-60 m, and after that the hole had diameter of 90 mm to the bottom. In 2002-2011 additional exploration of the oxide zone was done by air-drilled holes with direct circulation, core holes with Longyear application and trenches. Exploration core drilling was done by stationary aggregates of drilling rigs ZIF-650 and SKB-5. The holes were drilled under the angle of 60


111

degrees. Drilling was done with diameter of 108 mm to the depth of up to 5 m. After installation of a collar pipe the drilling continued by the double core equipment Longyear. The diameter of drilling was 76 mm, diameter of core was 40-42 mm. Average yield of core was not less than 90%. Core was marked and stored to the standard boxes. Air-drilled holes were designed for studying oxide gold mineralization in subsoil and in technogenic formations above ground water level. The diameter of drilling was 76 mm. Yield of slurry material was 59-100%. For confirming the quality of air drilling in the technogenic formations on the dump surface 8 trenches with the depth of 2.5 m were made in the holes profiles. Trenches were tested by the vertical trench samples with the length of 2 m. The results of comparing trench samples of the walls of trenches and upper intervals of air drilling show satisfactory matching. 2.5.4. Geological-geophysical conditions of the deposit Geological exploration of holes was done in 1969-72 with application of the following complex of geophysical methods: electric logging in the exploration holes with the depth of 200 and more meters in modification of resistivity logging, spontaneous polarization and electrode potential; measurement of natural radioactivity of the holes sections; measurement of holes crookedness; induced polarization logging; SP Exploration; Electrical correlation method on constant current. All works have been carried out in accordance with the requirements of instructions and projects. Measurement of holes crookedness was done by inclination compasses of ISh-4T, MK-2, UMI-25 type with the rise of point space being 10 m. Works by holes geophysics method were conducted using VPS-63 station. The oxide zone does not stand out in magnetic and gravitation fields. Ore zones stand out only visually (hydrothermal-metasomatic changes) and by the data of sampling. In order to determine the thickness of oxide zone, it is possible to use VES survey (and other modifications). Down-hole survey has been carried out (inclination compass MI-36) with spacing of 20 m since 2005. 2.5.5 Sampling and Sample Handling During the first stage of field works (1969-72) systematic sampling of mine workings was carried out in the process of drilling those workings. Trench samples with the length from 0.1 to 1-1.2 m with trench section of 5x10 cm were collected. In the mine the samples were collected from all four walls, moreover, continuous vertical sectional sampling (the length of section being 0.2-1 m) was carried out on the eastern and western walls and horizontal trench samples were collected every 1-1.5 m vertically on the south and north walls. Detected quartz veils with thickness of more than 15 cm and their selvages were sampled separately. In the roadways workings were sampled in 1-2 m of drilling by horizontal sections. In each section 2-3 trench samples with the length of 0.3-1.2 m were collected. Collection of trench samples from ditches and bell-pits was done using the same method as from underground workings and sampling pit (of mine) with the only difference that the samples from host rock without visible traces of hydrothermal changes on trenches and bell-pits were collected by pit samples with the length of 3-5 meters.


112

Sampling of the ore body in the open pit was done by trench method. Trenches were located transversely to the ore body each spaced 10 meters along the strike, the length of one sample varied from 0.1 to 1.0 m with trench section of 6x8х10 cm. Slurry sampling was done with the air-drilled holes. Only ¼ of the whole material was collected to the sample. Separation of samples was done in preventer. In order to justify representativeness of slurry sampling of unconsolidated technogenic formations, the validation of upper interval of air-drilled holes sampling drilled at the dump by vertical trench samples in the walls of ditches was carried out. The relative value of a particular error is 25.42% and this is within the allowable limits. Comparison of the sampling results of air-drilled holes and ditches applying the Student’s test surely proves non-availability of a systematic error. The trench sampling of technogenic formations of the dump was done on the wall of a ditch. The section of the trench was 10x3 cm. The length of the section was 2 m. The location of the trench was vertical. Core sampling was done in core drilling holes. The length of samples was from 0.8 to 1.5 m (average of 1 meter) depending on the lithological differences and the degree of hydrothermal changes. Core material of a sample was divided into halves by the long axis with a diamond saw. The weight of a sample was approximately from 1.3 to 2.8 kg with core diameter being 40-42 mm. The samples were sent to Kvarts Chemical Analytical Laboratory (CAL) for sample preparation. The rest of the core material was stored in wooden boxes at the core warehouse of Sage Creek Gold Company (Stepnogorsk). Two technological samples No.1 and No.2 (with weight of 600 kg each) from the underground workings from the horizon of 30 meters were collected in 1969-72 at the Dombraly deposit for technological analysis on gold extraction from the ores and its material composition. The parameters of technological samples are shown in table 2.6.

In 2004 the laboratory sample DLT-1 of 525 kg was collected from the open pit for determining the possibility of processing oxide ores by heap leaching method. In 2005 the additional laboratory sample DLT-1 of 500 kg was collected for studying technological characteristics of the dump. Technological analysis was carried out in Kazmekhanobr (Almaty). For clarifying the lower border of the oxide zone and technological characteristics 11 samples of 1 up to 2 kg (metallurgical sampling) were collected in 2005 in core holes. These samples were sent for analysis to Kazmekhanobr. Material from the tailings of core samples processing was used for forming these samples. In order to determine the bulk weight and moisture content in the ore of the Dombraly deposit, 35 paraffin-lined samples from underground working and holes were collected in 1969-72 and sent for analysis to the laboratory of the Aksu deposit. Two monoliths with dimension of 50x50x50 cm were taken for the same purpose from crossways III, IIIa and IVa and sampling pit of 1x2 m2 in section was drilled in ored body I between ditches No.28 and 32a. In 2004 pillars from re-cultivating mass and technogenic formations of the dump were collected. The total number was 5 pillars from 56.8 to 61.8 kg. Crushing of samples was done using mainly two approaches. First – irregularity coefficient in Richards-Chechautte equation is equal to 0.2. This approach was applied to samples collected from deep prospecting holes, original weight of which did not exceed 0.5-1.5 kg, and samples collected from weathered crust and from ores without visible ore mineralization with weight of up to 6 kg. Samples collected from ore intervals, quartz veins, mineralised zones were processed using the approach with irregularity coefficient being 0.8 (with highly uneven distribution of components). In 2002-2005 coefficient of 0.5 was accepted by analogy with operating gold fields of Kazakhstan oxide zones with uneven gold distribution (Central Mukur, Miyaly, Zhaima, Dzherek, Mizek, Uzboi, etc.). The final diameter of crushing was 0.074 mm. The samples were processed in Kvarts Chemical Analytical Laboratory. 2.5.6. Assay Works Assay works were carried out in chemical laboratories of AKSU, Zholymbet and Tselinograd Exploration Company in 1969-72. The quality analysis of samples collected at the Dombraly deposit in 1969-72 was systematically (twice a year) checked by the internal audit of the laboratory, where the main analyses were carried out, by repeated analysis of coded duplicates of the original samples. Internal audit of samples assay tests was carried out to the volume of 3-3.5% from the total number of samples in the laboratories carrying out main assay works. External audit (3-4%) of assay works of Tselinograd laboratory was carried out in the laboratory of Aksu mine, and analyses of Aksu laboratory were checked in the laboratory of Tselinograd Exploration Company. The functions of arbitrary control were imposed on the Central Laboratory of Kazzzoloto. The total of 110 samples was sent for internal and external geological control. In 2002-2005 the following types of assay works were carried out: Assay of core, trench and chip samples for gold (3241 analyses);


114

Atomic-absorption analysis for gold of core and chip samples (2309 analyses); combined samples analysis. Assay test was done in Tsentrgeolanalit CJSC (Karaganda), atomic-absorption analysis was carried out in Reaktiv LLP and Kvarts Chemical Analytical Laboratory. Combined samples were analyzed in Tsentrgeolanalit CJSC. Assay tests for gold, atomic-absorption analysis for copper, lead, zinc and silver, spectral assay for 16 elements, complete silicate analysis, neutron activation analysis for platinum, chemical analysis for total sulphur, sulphide sulphur, sulphated sulphur were carried out on samples. Internal geological verification of assay tests was conducted in Tsentrgeolanalit CJSC, external geological verification – in the laboratory of Kazmekhanobr. Samples collected from one duplicate of prospecting samples were sent for internal and external verification. The total of 589 samples was sent for both types of control compiling 5.1% of the total number of assay tests for this period. Assay tests were not conducted and samples for geological verification were not collected during the second half of year 2005. The results of external and internal geological verification of 1969-2006 show good reproducibility of results. 2.5.7. Determining bulk weight In 2004-2005 determination of a bulk weight and natural moisture of ore in situ was done on the basis of paraffin-lined samples applying standard methods in the laboratory of Reaktiv LLP. The total number of samples collected was 55, and 26 of them were the samples of oxide ore from middle and lower horizons of oxide zone and 29 samples on gold sulphide ores. It was determined that the bulk weight of oxide ores was 2.58 t/m3, for gold sulphide ores – 2.62 t/m3. Estimated average values of bulk masses are in good consistency with bulk weight dependency on depth diagram. Thus, for oxide ores, average value of bulk weight corresponds to the interval of depths of 160-90 m, within the limit of which the principle reserves of oxide ore are located. In 2004 pillars from re-cultivating mass and technogenic formations of dump were collected. The total number of 5 pillars with weight from 56.8 to 61.8 kg was collected. Weighting was done after samples collection and drying in drying cabinets for 2 days. Bulk weight of re-cultivating formations in the outline of open pit was 1.73 t/m3, for technogenic formations of the dump it varied from 1.58 to 1.77 t/m3 with the average of 1.66 t/m3. Due to the fact that the bulk weight was determined in preliminarily dried samples, adjustment to moisture wasn’t applied to reserves calculation. 2.6. Ore material composition Two native varieties of gold-containing ores (oxide and primary) are allocated at the Dombraly deposit. Oxide zone ores are represented by brown, yellowish-brown, rarely by bright-red quartz-ferrous-clayish saprolites on igneous-sedimentary rock. Sulphide minerals are fully oxidized and leached. Oxide zone is characterized by the large amount of secondary iron minerals: limonite, hematite, goethite, hydrogoethite and others. The ores in most cases are pored and cavernous, it is usual for them to have the blebs of sulphide leaching out. Material composition of oxide ores is shown in table 4.3.


115

Gold distribution in oxide ores is uneven. Gold content reaches 10-70 g/t in rod quartz veins and silicification zones. In highly oxidized, disintegrated and ferruginized selvages the content of gold reaches 0.3-7.0 g/t. Content of silver in oxide ores varies from traces to 5-10 g/t. Besides silver, there is a small amount of zinc and arsenic in the oxide ores. Arsenic content reaches 0.15%, zinc – 0.34%. The leading positions in oxide zones are reserved for iron minerals: hydrohematite, hydrogoethite, limonite, and less of jarosite. Gold nuggets are occurring in polished thin section. There are some barren minerals like quartz, barite, montmorillonoid, illite, sercite, kaolinite. The gold occurs in quartz (mostly) in host rock of oxide zone and in crystal lattice of pyrites in finely dispersed condition. Relations of gold with other minerals were not detected. The form of gold in quartz and in side weathered ores is characterized by a wide variety: sponge, vein-like, cloddy, dendrite-like, sheet-like, scaled grains adapting to intergranular space in quartz, in microcracks, etc. Sponginess of gold grains is due to fine grain coarseness of quartz. The value of gold discharge varies from 0.1 mm to 0.2-0.5 mm, the chemical composition of gold is noted for its changeability. Gold fineness variation limits is 800-950. The major part of gold (80% from the amount of analyzed gold grains) is rated 800-825, the rest – 900-950 and even 990 (as per data of atomic-absorption analysis (Central Geological Research Institute for Nonferrous and Precious Metals, 1970). There are no intermediate values between rates 800 and 900. In such manner, two types of gold (fine gold and medium-quality gold (800-850) are recognized by the chemical composition. According to the data of microspectral analysis, gold contains silver 5-20%, traces of lead and iron. The gold is of coarse-grained structure (0.04-0.4 mm) with narrow penetration twins. Gold-sulphide ores are characterized by impregnated, spotty, stringer-porphyry and pocket-impregnated textures. Textures depend on replacement of brecciated sedimentary rock by quartz-feldspathic aggregare by filling space between fragments of fine-grained sulphide mass. Ore structure is idiomorphic-grained formed by prismatic grains of arsenical pyrite and cubical grains of pyrite. Sulphide content in ores varies from part of a percent to 15-18%. The main ore minerals are pyrite and arsenical pyrite. There are affluent quantities of gold, galenite, sphalerite, copper pyrite and hematite. The main barren mineral is light-gray compact, fine-grained and anisometric quartz. Stripes of potassic feldspar and impregnation of sulphides are frequent in quartz. There are two mineral associations: early gold-quartz association and later gold-sulphide association. In the latter, there are pyrite-arsenic pyrite and gold-sphalerite-chalcopyrite, late. 2.7. Natural and Commercial Types of Ores There are two natural and commercial types – oxide gold-bearing and gold-sulphide ores at the deposit. Oxide ores are developed from the surface to the depth of 60-140 m. The depth of oxide zone is primarily defined by intensiveness of tectonic processes in ores. Oxide zones on the flanks of the deposit and in general on the territory of ore field is 60-80 m. The lower border of oxide zone of the central part of the deposit goes down to 140 m (the area of profiles No.24-36). Analysis on leaching out gold from the ore of the Dombraly deposit with column tests allowed making the following conclusion: the ore of the Dombraly deposit is suitable for heap leaching processing; expected commercial extraction of gold from granular ore of the Dombraly deposit will be from 45.18 to 74.60%;


116

The ore sample DLT-2 of the Dombraly deposit related to sulphide gold-containing ores with admixture of carbonaceous shales contain 6.5 g/t of gold and 7.7 g/t of silver, total sulphure – 1.74%, sulphide sulfur – 1.71%. Arsenic and carbon are the harmful impurities in the ore. On the basis of rational analysis it is seen that the gold in the ore is mainly available in free form and in aggregates – 81.63%. Testing on gravity washing of the ore was done on the concentration table KC-30. The results of the gravity washing of ore of 65 grain size and 85% gr. – 0.074 mm show that gold can be extracted to gravity concentrate. The results of chemical analysis show content of arsenic in gravity concentrate on the level of 3.5%, and stibium of < 0.005%. Two alternative of flotation diagram were tested: with extraction of carbonaceous shales and further sulphide flotation and a regular sulphide flotation. Ore flotation testing was done in laboratory conditions in a mechanic flotation machine. Sorption leaching is the effective method of processing gold-containing carbon-bearing ores. Anionite AM-2Bwas used for analysis of sorption leaching of gold from ore. Gravity tailings of 65% grain size gr. -0.074 mm were additionally crushed to 85% gr. -0.074 mm for carrying out tests on sorption leaching of gold. The following tablulation shows extraction of gold from the ore by different methods:

Ore Washing Gold Recovery %

Gravity washing 53.45 Ore Flotation 86.13 Gravity-flotation of gravity tailings 85.25 Ore cyanide leaching 17.65 Sorption leaching 79.23 Sorption leaching of gravity tailings 64.87 Gravity – Sorption leaching of gravity tailings 83.65 Sorption leaching of gravity concentrate 92.37 Gravity – Sorption leaching of gold from gravity tailings with account of processing gravity concentrate by Sorption leaching method

79.57

Different alternatives of ore washing were tested in the course of analysis. By gravitation method, 53.45% of gold is extracted to gravity concentrate from the ore, with gravity concentrate yield being 3.53% and gold content in it – 61.5 g/t. By flotation method, 86.13% of gold is extracted from the ore. Flotation concentrate yield is 13.59% with gold content in it – 27.4 g/t. Direct leaching of ore allowed extracting only 17.65% gold to cyanide solution due to availability of carbonaceous shales being the natural sorbents in the ore. Sorption leaching extracts 79.23% of gold to resin from the ore and 64.81% of gravity tailings. Combined methods of ore washing ensured gold extraction: gravity – Sorption leaching – 83.65%; gravity – sorption leaching of gold from gravity tailings with processing of gravity concentrate by sorption leaching – 79.57%. Gold-containing ore DLT-2 of the Dombraly deposit can be washed by two methods – ore flotation and sorption leaching.

2.8. Flowsheet for processing oxide ores Flowsheet for processing oxide ores was prepared on the basis of results of technological survey of ore (sample DLT-1) and tests of technogenic formations of the dump of the Dombraly deposit (sample DLT-1 additional). Process flow diagram: two-stage crushing with screening before the second stage; agglomeration using Portland cement; heaping sintered ore by radial stacker; leaching out gold from the ore by cyanide solution; sorption of solved gold by resin with output of concentrated sorbent and barren solution, to which required reagents are added for further return to processing; desorption of gold from resin, electrodeposition of gold from desorbent; preparing Dore gold. The output commercial product of the process is a gold-containing Dore bar, base gold of TS 98 RK-1-93 sent to a gold refinery for metal separation. 2.9. Hydrogeological conditions Engineering-gological, hydrogeological and environmental surveys at the Dombraly deposit were conducted by Karagandy Branch of Azimut Energy Services JSC under the agreement with JV Saga Creek Gold Company LLP in 2005. The landscape of the deposit is an elevated hilly-undulating plain. On the top this plain is formed by thin cove of the Quarternary eluvial-diluvial formations. Weathered crust is distributed widely across the site. It consists of loamy, rubbly-loamy and rubbly parts with the regular increase of fragmentary material content in deeper parts and transfer to fractured (exogenous) zone. The total thickness of the weathered crust varies from 20 to 60 m on area and up to 120 m in the zones of tectonic disruptions. Water in the weathered crust is related to rubble and grus material. Besides availability of the weathered crust, lithology of water-bearing masses defining the nature of rock jointing, filtration properties, quantity and composition of soluble salts released during weathering process also influences the quality and quantity of underground waters. Water occurs in upper rock jointing of the Paleozoic formations that often combine with the interstitial waters of weathered crust into one hydraulic system mixing by circulation and, in such manner, become the unified complex of weak pressure interstitial water. The depth of water circulation is defined by the depth of cracks and the nature of rock jointing. In effusive rock, jointing spreads to the depth of 30-35 m, and in sand-rock – up to 50 m. Static levels of underground water occur on the depth from 15 to 26 m depending on hypsometric holes location. In general water content in the rocks is low. Maximal flow rate is noted in the holes located within tectonic zones and it is 0.8-1.0 l/s with corresponding lowering to 17.2-9.5 m and it is 3-8 l/s with lowering to 8.7-8.5. On the basis of pumping-out data, rock filtering coefficient varies from 0.06 m/day (hole 3, 29) to 0.54 m/day (hole 27, 28), average – 0.06-0.20 m/day. In holes 16э and 35э pumping out flow rate was correspondingly – 8 and 3 l/s, with lowering to 8.5 and 8.7 m filtering coefficient was 4.63 and 2.4 m/day. The holes are located in the tectonic disruption zones and that’s why such values of coefficient are not representative of the site and are not taken into consideration during water inflow estimation. Underground waters mostly feed from precipitation. Feed areas are located outside the work site on the elevated areas, because bottoms of liars and sais are formed by rather thick clayish formations with weak water filtering capacity. Local underground water-flow goes on upper zone of rock fracture, regional underground water-stock – on large areas of tectonic disruptions. Underground water flows in local base level of erosion – Kop’s tract – located 3 km from the open pit.


118

Regarding the level of mineralization, ground waters being of sporadic distribution are slightly salty (1.3-2.2 g/dm3). Underground water of rock fracture zones is fresh with mineralization from 0.4 g/dm3 (hole 27) to 0.8 g/dm3 (hole 35) and slightly salty with mineralization of 1.4 g/dm3 (hole 29). By chemical composition, fresh water is hyrdocarbonate, chloride carbonate and hydrocarbonate-chloride calcic-and magnesium-sodium with total hardness of 3.8-5.8 mg-eq, neutral. Slightly salty water is hydrocarbonate- and sulphate-chloride magnesium-sodium and sodium, with total hardness of 7.9-1.10 mg-eq, neutral. Spectral and X-ray spectrum analyses in dry residue of water and chemical analysis of water did not detect excess of any chemical elements (according to Maximum Allowable Concentration for potable water in terms of total mineralization). 2.10. Mining and geological conditions Geological survey works were conducted at the deposit. Design phase – engineering documentation. The program of geological survey works provided drilling of 24 holes (No.1-24) with the depth from 6 to 70 m. During the process of field works, additional holes 1a and 21a were drilled for more detailed analysis of ground in the places of intense landscape change, where there was the probability of geological structure change. Holes were drilled by spud method by UGB-50M machine, d=132 mm, without hole casing. Holes 19 and 20 were drilled by core drilling with URB 2A-2 machine, d=132 mm, to the depth of 70 m. Total metreage of drilled holes was 301.5 running meters. Monoliths and samples were collected from all holes. Prepared the map of filtration fields of heap leaching area. Analysis showed that the main section of the area was formed by weakly permeable grounds (Coef.=0.005-0.3 m/day). Clays with filtering coefficient being <0.005 m/day (water-resistant) are of sporadic distribution in plan view, and in depth. This is why it will be required to lay additional hydro insulating layers during construction of PKV. Topsoil is available almost everywhere. Its thickness varies from 0.15 to 0.3 m. Humus content as per lab analyses data is 0.7-7.7%. All field, laboratory and data processing work was done in accordance with the regulatory documents effective on the territory of the Republic of Kazakhstan (the RoK SNiP (Construction Rules and Norms) 1.02-18-2004; the RoK SNiP 5.01-01-2002; SNiP 1.02.07-87; SNiP 2.02.01-83*; SNiP 2.03.11-85; the RoK SNiP 2.04-01-2001; SNiP 2.01.07-85*; GOST 25100-95; GOST 9.602-89; "Guidelines for Designing the Foundations of Buildings and Constructions” to SNiP 2.02.01-83; SNiP IV-2-82, etc. ). Soil characterization was done in accordance with table Б.1=3 of GOST 25100-95. As per the conditions of drilling in soil, according to SNiP IV-2-82, topsoil is related to group I-II, Quartenary clay foam – group II-IV, sand clay and clay foam – II-IV (§ 33g), clays – II-IV (§ 8d), rubbly soil –groups IV-V (§ 31а), argillites – group V (§ 31b) depending on the method of development. 2.11. Methods of opening and field development The method of the oxide zone development – open pit mining. The borders of open pit mining are set with account to inclusion to mining of all commercial reserves of the oxide zone.


119

For open pit mining to the horizon of 90 m, opening by internal entry ditch that transforms into stationary transport access tracks on the way down is provided. Slopes are under the angle of 65 degrees, open pit walls – 51 degree, the width of berms is 5 m, of ditches and access tracks – 15 m. Development system – transport system by descending horizontal layers with transporting overburden to external dump, ores – to ore site and partially to the batches of agglomeration complex. In near-contact zones, in order to reduce losses and dilution, selective mineral extraction with storing offgrade ore in out of balance ore dumps is provided. Ore and overburden rock hardness coefficient as per the classification of M. M. Protodiyakonova is 8-15 (SNiP group – VII-IX), blastability grade – V. 2.12. Method of Reserves Estimation Reserves estimation was carried out in 2008 by the method of vertical geological open cuts separately for oxide and primary gold-containing ores, re-cultivating mass within outline of open pit and technogenic formations of the low grade stockpile. Geological peculiarities of the deposit, methods of its exploration and development were taken into account when choosing a method for reserves estimation. The following was aiding to estimation: drilled holes and workings located on 10 profiles in latitudinal direction (53 holes, 19 bell-pits, 8 ditches, 24 crossways, 206 air-drilled holes, 61 line of trench sampling, 7089 samples). Interval between profiles is 40 m, except the interval between profiles 0-7 (80 m). Directly for estimating reserves were used 40 holes, 3 ditches, 4 crossways, 17 lines of trench sampling, 163 air-drilled holes and 1422 samples, with which the reserves of ore were blocked. Estimation of oxide ore reserves was done using evaluation conditions approved by the RoK State Reserves Committee (Minutes of Meeting No.496-06-K dated 21.03.2006): cutoff gold grade in sample – 0.3 g/t; minimal thickness of ore bodies included in reserves estimation – 2 m; with lesser thickness, but high gold content the appropriate GT should be used; maximal thickness of barren rock layers or offgrade ores used in reserves estimation – 4 m; estimation of poor ore reserves being re-cultivating rock within the outline of earlier developed open pit should be done by total mass. Nominal conditions accepted by analogy to evaluation conditions of primary gold-containing ores of the Uzboi deposit (underground mining) approved by the RoK State Reserves Committee were used for estimating reserves. Outlining oxide ore bodies was done on the basis of the data of ditches, mines, roadways, crosscuts, sampling pits, actual mining horizons and holes to the depth of oxide zone. The lower border of the oxide zone was drawn upon detection in the rocks of carbonaceous material relics and first traces of sulphide. Border of the oxide zone is shown on a layout mainly on the basis of primary documentation data. Outlines of ore bodies were reconstructed on estimated section of 1:500 scale and assay plans of 1:500 scale. Ore bodies border were drawn through a final sample with cutoff gold grade of this alternative. Between ore and barren roadways the outline was drawn on the half of distance between them, but not more than 25 m. In case of non-availability of outlining roadways and thickness of ore intersection more than 2 m, the outline was drawn to the distance of 25 m downwards (along the strike), with thickness 2 m and less – to the distance of 12.5 m.

Estimation of re-cultivating rock reserves within the outline of the open pit and technogenic formations of the low grade stockpile was done by the method of vertical sections. Reserves are classified under C2 category. The main exploration minings were air-drilled holes. Representativeness of chip sampling of technogenic formations was confirmed by trench sampling of ditch walls. Sampling was done only of the upper above-water part in re-cultivating formations of the open pit. The results of holes sampling are considered to the whole volume of re-cultivating formations. The bulk weight of re-cultivating formations was 1.73 t/m3, for technogenic formations of the low grade stockpile – 1.66 t/m3. 3. General Information of the Shirotnaia Deposit The Shirotnaia deposit is located in the southeast part of Alhambra Resources licensed site, 8 km north from Stepnogorsk and 100 km from its operating open pit – Uzboy .

Photos 4 and 5. Landscape of the Shirotnaia deposit 3.1. Geological Structure of the Shirotnaia Deposit Volcanic formations of the Mid-Ordovician period and Quarternary alluvial formations form the structure of the deposit. Mid-Ordovician is represented by volcanic-sediment deposits, mainly by tuffs of average compostion with lens-shaped bodies of diorites of upper Ordovician age, quartz andesite, volcanic brecciates, siltstones, fine-grained sandstone with rare layers and lenses of limestone, tuffs and quartzrock bodies. Rocks of the Mailysor late-Ordovician sub-volcanic complex represented by andesite-dacitic porphyrites are quite frequent. Ore mineralization is located in the Aksu zone of disruptions of north-east trending with 45о trend azimuth and is clearly seen on the joining section and intersection of splits of different orientations. 3.2 Methods of Geological Exploration Works In 2002-2004 in the north-western part of the deposit area, ditches in profiles every 40-80 m were drilled, as well as 5 profiles of air-drilled holes with drilling step – 5 m. On the basis of the results of these works, 4 ore bodies were detected with cutoff gold grade of 0.5 g/t and the range of small lenses. The length of ore bodies was 240-540 m, and thickness from 1 to 15-20 m. Gold reserves were estimated to the depth of 30 m and amounted to 1500 kg with average content of 1.62 g/t. In 2005 prospect-evaluation survey was carried out in south-east part of the deposit area within a swamped valley. Works were conducted by digging ditches and drilling RCC holes. Ditches were done in profiles every 40 m, their depth did not exceed 1.5 m due to high level of underground water.


121

The volume of ditches digging was 2097 m, the number of collected trench samples – 2023. RCC holes were drilled in the lines of ditches profiles by grid 80x10-20 m to coming to transition zone rocks. The volume of drilling was 3797 m, the number of collected core samples – 1864. The depth of the oxide zone was 30 m. As a results of 2005 works, large sub-lateral ore body of complex morphology. Along the strike it was traced for 700 m. In the central part this ore body’s thickness increases to 97 m to the length of 160 m, on the flanks the thickness of ore body decresed to 2-9 m. Ore body is inclined 60-75° to the north-west. Three band-like mineralization zones with thickness of up to 6-10 m were detected on the bottom layer close to the main ore body. In 2006 prospecting and evaluation works were continued on the south-west flank of mineralization and its central part. Ditches were drilled on the south-west flank every 40 m, their average depth – 1.8m. Volume was 3845 m, the number of collected samples -3711. RCC holes were drilled in the hanging wall and bottom of the main ore body by grid 120-80x10 m to exit to solid rock. Drilling volume was 197 holes with the depth of 27.6 m, total length of 5443.5 m, total of 2083 samples was collected. As a result of these works, earlier stated reserved of the central part of mineralization and its south-west were confirmed. On the south-east flank 520 m away from the main body, columnar mineralization with north-west inclination to 50-450 was discovered. In 2007 main prospecting works and depth exploration of the main ore body were conducted. The purpose of the prospecting works was to discover gold mineralization zoned to the depth of 4 m on the north-east and south-west flanks. Deep-earth geochemical survey of the territory of 27.7 km2 by grid of 200x50-20 was conducted here. During this period 818 small-depth holes with the length of 3760 m, 1120 samples were collected. Exploration of the main ore body and south-west flank of the mineralization was done by core holes to the depth of 120-140 m. There were 18 holes drilled to the length of 2117 m, 2001 sample was collected. Prospective areas on the north-east flank were discovered on the basis of prospecting works of 2007. Drilled holes opened columnar main body on the depth within 100x80 m with north-west inclination to 60-7- degrees. In 2008 works were carried out in three stages: First stage – continued prospecting works on the east, west and south-west flanks by deep-earth geochemical logging by grid 500-1000x50 m on the area of 45 square meters. There were 1893 holes drilled with total length of 8723 ml 2995 samples were collected. On the basis of these works’ results secondary haloes of gold were built. Second stage – conducted drilling works on secondary gold haloes. The latter were traced to the distance of 1800 m from the main ore body to north-west by grid of 200x10 m, drilling volume was 20891 m, 10449 samples were collected. Third stage – exploration works (air drilling) was carried in discovered zones and ore bodies by grid of 40x5 m along the strike to the distance of 500 m. The volume of drilling was 7218 m, collected 3609 samples.

Approximate reserves estimation on the oxide zone of the deposit on С2 category was conducted by the Geology Department of the company and is (as of 01.01.2010): ore – 3250 thous. t. ; gold – 3900 kg; average gold content – 1.2 g/t. Oxide ores on P2 category: ore – 33 300 thous.t.; gold- 40 000 kg; average content- 1.2 g/t. 4. Visiting the Dombraly and Shirotnaia deposits Geological exploration works on the deposits are carried out according to the conventional Soviet geological methods. Documentation of the mine workings and holes is carried out directly at the mine sites. Sampling and processing samples are conducted on the territory of the Saga Creek Gold Company’s gold processing plant.

4.1 Core documentation Core documentation is carried out during the core drilling process on a daily basis. Geological information records are entered into the documentation logs with compulsory requirement to fill in the table form with drilling intervals (runs), fixing the core length, % core yield, core sketches (separate fragments), the geological characteristics of the core by the layers of rocks and ores, sampling intervals and sample numbers. During performing geological task of the hole, the hole is closed by the district geologist, and check measurement of the hole is taken. After drilling is finished, Case (Passport) for the hole is composed, which includes geological documentation logs, drilling logs (conducted by the drilling foreman with filling in the drilling parameters and possible geology-technological complications), acts of initiation and completion of hole drilling, the act of survey measurement, the act of geological research (if conditioned by the project), the geologic column for the hole. Photos of core holes are taken in the position “box on the ground”. Hole documentation on the area of the deposits and fields is not produced in electronic form. 4.2. Core cutting Following the geological documentation and the selection of ore zones of mineralization, core holes are directed to the cutting along the long axis of the core. Only those ore intervals visually highlighted by the geologist are subject to the cutting. Core cutting is made on the machine produced in Russia under the supervision of geologist, on the territory of the Stepnogorskaya Mining Enterprise, a subcontractor of the drilling works. Diameter of diamond disc is 400 mm.

Photos 10 and 11. Cutting machine and core receiver Core is split into two halves. Detrital material out of cleavage zones with the fragment size smaller than the diameter of the core is split in half by hand. Following the cutting, core boxes filled with the sample material are delivered to the Saga Creek Gold Company’s core storage. 4.3 Sample preparation Core boxes are laid out in a special order on the paved area of the core storage. Geologist marks sample intervals, putting sample labels along sample borders that were strictly identified by the documentation. Sampler selects samples into the plastic sacks strictly according to the sample intervals by selecting core halves. Paper label with sample information (site, hole No., sample No., sample interval, Family name of the geologist, date of sampling) folds and fits into the sample sack. Hole and sample No. are signed on the sample sack. Selected samples of the holes are delivered to the core storage, where sample weighing and sample group formations for the sample preparation are performed.


124

Photos 12 and 13. Core prepared for sampling and sample group formation Selected samples are weighed on the scale of the РН-10Ц134 make, with a scale division of 0.05 g and are entered in the sample registration log.

Photos 14 and 15 . Sample weighing and selecting batch of samples Here, samples are distributed under orders to carry out analytical work. The second halves of the core are neatly stacked in core boxes. Boxes for the drill holes with the remaining core are closed and transported to the core storehouse. Later, if necessary, laboratory-technological samples would be selected out of the core remnants for the study of mineral and technological ore properties. Samples selected by the program of exploration works have been processed in crushing mill workshop of Saga Creek Gold Company’s gold processing plant in Stepnogorsk since 2009. Sample processing is performed using the Richard-Chechett' formula Q = kd2 at k = 0,5. Experimental validation of the coefficient of uneven mineralization was carried out on the field in 2005. Previously, samples were processed in other companies. In 2002-2004, the sample processing was carried out in the Reagent LLP (Stepnogorsk), in 2005-2009 – in Quartz Chemical Analysis Laboratory . Over the entire period of gold mine exploration grinding of the gold samples was carried out at K equal to 0.5. Scheme of the core sample processing is shown in the figure. Subsequent to the drying samples are sent to the first stage of the jaw crusher, where sample material was grinded up to 7 mm. Following the first stage of grinding crushed material is sent to roller crusher, where it is grinded up to 1 mm.

Photos 16 and 17. Jaw crusher of the VIBROTECHNIK company and disc eraser of Russian production After the second phase of fragmentation and reduction by the Jones index the bulk of crushed to 1 mm samples enters the geological sample storage as a geological sample duplicate, while sample itself weighing about 0.75 kg is directed to reduce to a particle of size 200 mesh (disk eraser). Batches for the production of atomic absorption and assays are selected from the sample material, and so are the batches for the internal and external control production. Remains of analytical sample are sent to the sample storage as analytical duplicates. Analytical samples themselves are grouped in separate orders and are sent to the Stewart Group laboratory (Kara-Balta, Kyrgyzstan). All instruments used for crushing and sample reduction are equipped with special instructions for operators. The workshop of the sample preparation is kept clean. After every sample preparation all appliances and countertops are cleaned and blown by compressed air without fail. Cleaning each batch of samples with inert material (granite, glass or any other dead rock) is not performed after crushing. 4.4.Storage of the geological sample and core duplicates Following sawing and hole sampling boxes with core are sent to the core storage. Core holes not penetrated the ore body are kept close to the core storage. Sample duplicates are stored in a specially designed sample storage building of the gold processing plant.

CONCLUSION AND RECOMMENDATIONS The Dombraly Deposit was studied with surface ditches, pipes, pits and deep exploratory holes and underground mine workings, passed in the horizon 30 m below the surface. The upper part of the oxidation zone of an open pit has been processed to a depth of 60 m. The pit is partially reclaimed. Material composition and technological properties of oxidized and gold-sulfide ore deposits as well as technogenic structures of Dombraly II deposit were studied by laboratory-technological samples and samples for technological mapping. Hydrogeological and geotechnical conditions of deposit development are simple. Reserve estimation of oxidized and gold-containing ores in mineral resources, gold technogenic mineral formations and dump recultivation rock in the open pit path was calculated. Delineation of oxide ore was produced in the bowels of evaluative condition, approved by the SRC RK (Minutes № 496-06-K on 21/3/2006 ), gold-sulfide ore - contingent condition, taken by analogy with an estimated body condition for sulfide ores for underground mining of the Uzboy deposit. Stocks of recultivated mass in the open pit path and TMO are estimated without cut-off grade of gold. The total reserves in the bowels of the oxidized ore, recultivated rock mass in the open pit path and technogenic deposits on the blade on С2 category were: 4254.1 thousand tons of ore, 6478.8 kg of gold, the average gold content of 1.52 g / t. Stocks gold-sulfide ore to a depth of 300 meters on C 2 category were: 575.6 thousand tons of ore, 3119.6 kg of gold, the average gold content of 5.42 g / t. Forecast resources of category P 1 to a depth of 500 m: 510.1 thousand tons of ore, 3072.6 kg of gold, the average gold content of 6.02 g / t. In general, for the deposit of С2+Р1: 5339.8 tons of ore, 12671.0 kg of gold, the average gold content of 2.37 g / t. Shirotnaia deposit is studied mainly within the development of oxidation zone. It established two zones of mineralization, including some of the ore bodies and lenses. Exploration network of traversed holes in the deposit will evaluate the deposit according to the C 2 + P 1 category. The deposit is very kindly, as evidenced by the estimated valuation of resources in the zone of oxidation by category C 2 and P 2, performed by the Geological Survey of Saga Creek Gold Company LLP. The deposit requires exploration to be continued in the upper levels for category C1 stock for oxidized ores and exploration of primary gold-sulfide ores. Exploration works are carried out by qualified personnel in accordance with existing procedures. Additionally, recommendations are as follows: Keep the mouth of the exploratory open pits by leaving a pipe of 0.7-1.0m length above the surface with a designated hole number and the date of drilling hole; Conduct geological hole documentation in electronic form (Word), without giving up the log records documentation; Make a design for hole photography at 45 0; Cut out ¼ part of the core of each 20th ore sample for quality control of samples and determine the probable non-uniformity of mineralization (the direction of a reference laboratory); Apply the "single, obviously empty" samples, along with certified samples.
