Executive Summary

This report presents results of the geochemical characterisation of waste and mineralised material

from the Sinosteel Midwest Corporation Weld Range Project.

Overall Objective

The overall objective was to determine the potential for waste rock, stockpile material and pit walls

to be sources of acid drainage and metalliferous leachate.

The findings were used to define a simple method of classifying mined rock as potentially acid

forming (PAF) or non acid forming (NAF) during operation of the mine.

Outline of work programme

Design and implementation of a sampling programme – Drill core and the block model were

reviewed to identify samples representative of the major domains and weathering states of waste

rock and mineralised material. Samples identified were within or immediately adjacent to the

Madoonga and Beebyn pit shells designed in the prefeasibility study.

Since collection of the samples, the project has progressed to the bankable prefeasibility value

improvement stage (BFS VI) which includes a larger pit design based on two products (MWB and

Spot Market Ore).

Two hundred and sixty five samples of waste material and 74 samples of mineralised material were

collected for geochemical characterisation. The block model was used to estimate the mass of each

material in each domain.

Design and management of a static test programme – A static test programme provided data for

the assessment of the potential of materials to produce acidic and metalliferous drainage (ADML).

Parameters measured included paste pH and paste electrical conductivity, total sulphur, sulphate

sulphur, total carbon/total inorganic carbon, acid neutralising capacity (NP), net acid generation

(NAG), whole rock chemical assay and the acid buffering characteristic curve (ABCC).

Data interpretation – Static test results were interpreted to identify sources of acid potential and

acid neutralising capacity and to classify samples as potentially acid forming (PAF), non-acid

forming (NAF) or uncertain (UC). Elemental abundances were compared with average global

abundances, and element leachability assessed.

Design and implementation of a kinetic test programme – A subset of 13 samples that included

samples classed as PAF, NAF and UC were tested in columns a) to obtain an indication of rates

oxidation, acid neutralisation and solute release and b) to assist in identifying criteria that separate

PAF materials from NAF materials. The kinetic test programme comprised modified AMIRA-type

column test procedures. Four columns operated for 16 weeks and nine columns had operated for 45

weeks at the time of preparing this report. An assessment of the need to continue column operation

was made.

Development of a simple classification system for use during mine operations – A simple

classification scheme was developed for a) constructing a block model that identified materials

with the potential to produce ADML and b) for classifying materials during mining. Materials

classed as PAF under the simple scheme would be segregated during mining and managed to

control the development and impact of acid and metalliferous drainage.

Results

Some materials contain stored acidity and at the time of mining they could have potential to release

acid. These materials include a significant proportion of the detrital (DID) and smaller proportions

of the felsic (FEL), banded iron formation, hydrated and mafic wastes. Similarly, small

proportions of the three mineralised domains (ORE, O_AL, O_SI) could also be marginally net

acid generating.

Generally there are limited quantities of soluble salts present, which indicate that flushing of the

mined materials prior to oxidation will not affect the solute content of water significantly.

Ninety one percent of the samples had a total sulphur content of less than 0.1 wt%. Thus, the

majority of material is expected to have a low maximum potential acidity (less than 3 kg(H2SO4)/t).

Neutralising potential (NP) is generally limited, average NP is often less than 15 kg(H2SO4)/t.

Carbonate-based neutralisation potential (CarbNP) was also calculated, but may overestimate NP

due to the presence of non neutralising carbonates such as siderite. The minimum of the NP and

CarbNP was the most appropriate measure of neutralising capacity available. A small number of

ABCC tests indicated that the actual neutralising capacity for some material may be less than the

minimum of the NP and CarbNP.

Some domains have little neutralisation potential and therefore would not be expected to provide

significant acid buffering capacity. The units include the MAF, DID, FEL, HYD, and high alumina

mineralised (O_Al).

Static and kinetic leach testing indicates that solute release rates are generally low under neutral

conditions and can increase under acidic conditions.

The masses of wastes at the Madoonga and Beebyn deposits classed as NAF, PAF and UC are

presented in the tables immediately below. Two classification schemes were used: the AMIRA and

neutralising potential ratio classification schemes. These schemes require quantification of acid

generation and neutralisation capacity and other parameters.

GARV/CHAP SMM004_ENV_RP_2_Rev1.docx March 2011

Based on the understanding gained from the static test results, a simplified classification scheme is

proposed for classifying samples as PAF or NAF. The classification of materials was based solely

on the total sulphur (total S) content of samples in relation to a total S cut-off grade (Sc).

The lower the value of Sc the larger the volume of material classed as PAF.

Data for Weld Range samples suggests that Sc may lie between 0.1 and 0.36 wt% S. The lower

bound value is based on NAG testing results, whilst the upper bound value is based on data from

kinetic tests.

Based on the lower bound Sc value of 0.1 wt% S and the PSF pit shell design the mass of material

that would be classed as PAF at:

a) Madoonga would be about 21 Mt

b) Beebyn would be about 3.3 Mt.

As the BFS (VI) pit shells contain about twice the mass of waste within the PFS pit shells it is

possible that mass of waste classed as PAF for the BFS (VI) pit shell would be about 49 Mt.

The mass of waste classed as PAF varies little for Sc values in the range 0.1 to 0.25 wt% S.

Examples for the PFS pit shell are given in the following table.

Sc (wt% S)

Mass of Waste Classed as PAF (Mt)

Madoonga Beebyn

0.0 130.7 233.2

0.1 20.6 3.3

0.25 13.1 3.3

It may be possible to obtain data that supports use of a larger value of Sc (and thereby reduce the

mass of waste classed as PAF). Such data could be obtained from the samples that were leach

tested for 45 weeks. A sample of material would be removed from the columns that produced

neutral pH at week 45 and tested to determine the quantity of oxidisable sulphur remaining in each

column sample. Laboratory costs are expected to be less than $2,500.

Recommendations

SRK recommends that:

1. That a simple scheme based on a threshold value of total sulphur content (Sc) is used for

classifying materials during mining. In the absence of further information on the acid

producing and acid neutralising capacity of materials the scheme would be as shown in

recommendations 2 and 3.

2. The value of Sc is taken as 0.1 wt% S.

3. Materials with:

a) Total S ≥ 0.1 wt% are classed as PAF and those with

b) Total S < 0.1 wt% are classed NAF.

4. An assessment is undertaken to determine whether use of a larger value of Sc can be justified.

A larger value of Sc would result in a smaller volume of waste being classified PAF. An

approach is presented in recommendation 5.

5. Operation of the long-term (45 week) kinetic columns should cease. Samples should be

obtained from those columns giving neutral leachate. These samples should be sent to a

commercial laboratory to measure the quantity of remaining oxidisable sulphide. The data

obtained will help determine whether a larger Sc can be used.

6. The current review of the quantity and distribution of PAF and NAF materials within the BFS

(VI) pit shell being is completed. Details are given in Section 5.1.

7. An assessment is undertaken of the potential quality of water that comes into contact the waste

and mineralised material. Details are given in Section 5.2.

Introduction 1.

Terms of reference 1.1

The Weld Range Project (WRP) is a Sinosteel Midwest direct shipping ore (DSO) project.

A prefeasibility was complete at the time of sample selection for geochemical characterisation.

Since the sample selection a bankable feasibility study (Value Improvement) based on a larger pit

shell was completed.

The proposed project includes the development of open-cut pits, stockpiling of ore, blending of ore

on site and construction of waste material landforms.

Sinosteel Midwest Corporation (SMC) engaged SRK Consulting (Australasia) Pty Ltd (SRK) to

carry out a geochemical characterisation programme to assess the potential for acid and

metalliferous drainage (AMD) from rock exposed during mining; including waste rock, mineralised

stockpiles and the pit walls. The assessment is to provide guidance for waste management during

operations and establish closure requirements.

Background 1.2

1.2.1 Project location

WRP is located 600 km NNE of Perth, 65 km southwest of Meekatharra and 50 km northwest of

Cue in the Mid West region of Western Australia. A location map is provided in Figure 1-1.

1.2.2 Regional Setting and Climate

The landscape has contrasting vegetation types, but arid shrub lands make up the vast majority of

vegetation types encountered. The arid shrub lands host a number of native plant species which do

not occur in many other bioregions. There are few or no trees or perennial grasses across much of

the landscape.

Summers are characterised by hot, dry days and mild to warm dewless nights. Maximum daily

temperatures during the summer range from 29 to 38 °C and the minimum daily temperatures range

from 14 to 22 °C. Whilst cyclones are not regarded as regular events in the Meekatharra district;

they do cause widespread heavy rainfall. Cyclones usually occur between November and April

when intense low pressure disturbances develop off the north-west coast of Western Australia.

Winter is characterised by mild days and cool to cold nights. Winter average daily temperatures

range between 6 and 19 °C in July and rise to 13 and 29 °C in October (Department of Agriculture,

WA).

At Cue the average daily temperature ranges from 7 to 18°C in July to 23 to 38°C in January.

Mean annual rainfall is 232 mm with the wettest months being January to July. Average annual

open pan evaporation is about 3 m per year.

1.2.3 Geological setting

The Weld Range Project includes the Madoonga and Beebyn iron ore deposits located in the Weld

Range. Both the Beebyn and Madoonga deposits consist of steeply dipping rock sequences dipping

SE at Beebyn and SSE at Madoonga. The rock sequences include banded iron formations (BIFs)

and dolerite.

At Madoonga sediments and sedimentary rocks lie above deeply weathered rocks. The local rock

sequence comprises, from north to south, a package of felsic (FEL) sedimentary rocks that are

overlain by BIF approximately 60 to 250 m thick. The lower part of the BIF contains a 5 to 10 m

thick shale unit. A 20 to 50 m thick zone of deeply weathered and altered rocks within which the

iron mineralisation is hosted, occurs in the hanging wall of the BIF. Mafic igneous rocks including

dolerite and basalt occur in the hanging-wall to the iron mineralisation.

The Beebyn deposit contains numerous BIFs interlayered with dolerite. The main BIF at the north

is approximately 40 m thick. Thinner BIFs to the south have thicknesses ranging from about 2 to

10 m. Least altered and unweathered BIFs contain millimetre to centimetre-thick iron-, silica-,

Fe-silicate- and locally carbonate-rich bands (Kenworthy and Hodkiewicz, 2008).

The mine plan includes development of open-cut pits, stockpiles and waste rock dumps.

Report scope 1.3

This report documents the findings of the geochemical characterisation tests carried out on samples

representative of waste material and mineralised material from the proposed WRP.

The geochemical investigation comprised both static and kinetic test procedures. The scope of the

geochemical testing programme is presented in Section 2 of this report. Section 3 presents and

discusses the outcomes of the geochemical investigation. Section 4 presents a discussion of

possible waste rock management strategies. Conclusions and recommendations are provided in

Section 6.

Geochemical Investigation Programme 2.

Overview 2.1

The geochemical characterisation of wastes and mineralised material began in April 2008 with the

selection of the first set of samples (Round A) for laboratory testing. A second set of samples

(round B) was selected in March 2009.

The samples were selected to represent materials within the pit shell of the prefeasibility study

(PFS) which was based on producing Mid West Blend (MWB) ore. Since collection of the samples,

the project has progressed to the bankable prefeasibility value improvement stage (BFS VI) which

includes a pit design based on two products (MWB and Spot Market Ore).

Based on the PFS study a total mass of waste produced at the Madoonga and Beebyn deposits was

approximately 364 Mt. The substantially larger pit of the BFS (VI) would result in a total

production of 712 Mt of waste. Currently a review of the block model is being conducted to assess

the similarities of materials from within the PFS pit and materials from between the PFS and BFS

pit shells.

The geochemical investigation of samples from within the PFS pit shell was carried out in two

phases.

Phase 1 comprised a scoping study to assess the overall magnitude of the potential for acid

generation based primarily on static test procedures. Sample selection was based on a site specific

block model, the available information on lithologies and degree of weathering and estimates of the

mass of each domain that would be mined. The programme was designed to i) identify domains

that may produce acid and those that may consume acid and, ii) determine the overall variability

within each domain.

Phase 2 was designed to establish the net potential for acid generation and determine metal leach

rates using kinetic tests procedures and supplemental static tests. Materials for testing were

selected based on the outcomes of Phase 1.

There are three main objectives of kinetic testing. They are to obtain:

1. Estimates of rates of sulfate release (oxidation).

2. Estimated rates of release of metals.

3. Estimates of times to the onset of acidification of the effluent.

A secondary objective was to identify a sulphur content below which materials can be considered

unlikely to produce acidic effluent. This sulphur content may serve as a criterion for classifying

materials as PAF or NAF during mining.

An initial report on the geochemical characterisation completed as of September 2009 was reported

in October 2009 (SRK, 2009). The current report documents geochemical characterisation work

conducted up to January 2011 including that completed as of September 2009.

Identification of domains 2.2

The Weld Range iron ore deposit is hosted in sedimentary rocks and comprises two mineralised

zones; the Madoonga zone to the west and the Beebyn zone to the east. Table 2-1 presents domain

codes used in the block model and a description of the corresponding rock types. The domain

codes represent a spatial grouping of rock codes and were developed by Sinosteel Midwest

Corporation.

Sampling 2.3

2.3.1 Sampling approach

A primary aim was to select samples from the major domains and a range of spatial locations from

within the planned pit. As some domains were not well represented in the drill core or cuttings

obtained from within the PFS pit shell a small number of samples were gathered from outside the

PFS pit shell.

SRK visited the Weld Range site in April 2008 and identified a total of 59 samples from the

available diamond drill core from the Beebyn and Madoonga deposits (Round A). Another

280 samples were selected in the second quarter of 2009 by SMC staff (Round B). The samples,

selected using the geological database developed during the prefeasibility study (PFS), represented

both the Madoonga and Beebyn zones and were obtained from diamond drill core where available,

reverse circulation (RC) cuttings or surface samples. Core up to 6 m in length was collected.

Table 2-2 presents the estimated mass of each domain (PFS estimate) that would be mined, the

mass distribution and the number of samples from each domain submitted for geochemical testing.

Since sample selection the pit shell has been altered. In the current design the pit is approximately

50 m deeper than in the PFS study. An initial review of drill hole locations and lithologies

indicates that all major lithologies present in the pit of the current design are represented by the

samples selected by the samples selected and reported here. A more detailed investigation of the

representativeness of samples and their spatial distribution to determine location of sulphur bearing

domains is recommended in this report.

2.3.2 Sample preparation

Core samples were crushed to 5 to 10 mm. Samples for static testing were further crushed to less

than 2 mm for paste pH and EC measurements and pulverised to less than 75μm for other chemical

analysis. A total of thirteen samples of core crushed to 5 to 10 mm were subjected to kinetic

testing.

Static testing methods 2.4

The static test parameters and measurement procedures used in the testing programme are

summarised in Appendix 2. The samples were sent to the SGS Laboratory in Welshpool, Western

Australia and Australian Laboratory Services (ALS), Brisbane for the static tests shown in Table

2-4. All samples from the first and second sampling programme were submitted for static testing.

Kinetic testing sample selection and methods 2.5

Samples for column leaching were selected to represent the majority of domains (waste and

mineralised), NAF, UC and PAF samples based on static testing and a wide range of total S

contents. The domains represented were BIF, MAF, DID, HYD, SHL, Ore, Ore Hi Al and Ore Hi

SiO2.

The material in the four columns of Round A kinetic testing had total S contents of less than

0.1 wt% and were column tested for 16 weeks. Nine Round B samples were column tested for a

total of 45 weeks and the total S content ranged from 0.1 to 23.8 wt%.

A modified AMIRA procedure (AMIRA, 2002) was used for kinetic testing. The principal

differences related to the particle size at which the tests were completed and the flushing regime.

Flushing was increased to a weekly (rather than monthly) schedule and the samples were crushed

to less than 10 mm (rather than -4 mm).

Results and discussion 3.

Static testing results 3.1

The complete static test results are presented in Appendices; paste parameters (Appendix 3), acid

base account results (Appendix 4) and net acid generation (NAG) test results (Appendix 5).

Elemental analyses are provided in Appendix 6 and Appendix 7. Multi-element analysis of leach

extracts are reported in Appendix 10. Appendix 11 presents acid buffering characteristic curve

results. The results are briefly discussed in the following sections.

3.1.1 Paste pH and paste EC

The paste pH and paste electrical conductivity (EC) test was designed originally to measure the

load of oxidation products associated with waste material that had weathered for extended periods.

In the case of drill core, test results have to be considered in the light of how the samples were

obtained (e.g. wet or dry drilling as the drilling fluids may interact to contribute to the test

outcome) and the state of weathering (i.e. how long the core had been in storage, how it had been

stored and handled etc.).

Paste pH generally provides an indication of the state of acid generation of the sample at the time

of testing; low pH values indicate the sample is net acid generating whereas near neutral to alkaline

pH indicates that acid generation has as yet not occurred. It however cannot be used to infer that

acid generation will not occur.

In general, a high electrical conductivity is used to infer soluble salts from oxidation, however, in

the current samples the results only indicate salinity already present in the sample (i.e. evaporites or

naturally saline pore water) and not necessarily generated from oxidation.

The samples were obtained from drill core and drill cuttings that were stored in core trays for up to

18 months before testing and may have undergone some oxidation.

The majority of paste pH values were in the neutral to alkaline pH range, as shown in the

cumulative distribution plot provided in Figure 3-1. About 1% of the samples had paste pH values

below 5; one sample from each of the shale (SHL), hydrated (HYD) and banded iron formation

(BIF).

The percentages of samples in each rock type with paste pH values between 5 and 6 are presented

in Table 3-1. These results suggest that a significant proportion of the detrital (DID) and smaller

proportions of the felsic (FEL), banded iron formation, hydrated and mafic wastes could be

marginally net acid generating. Similarly, small proportions of all three mineralised domains could

also be marginally net acid generating. Drainage from the mineralised materials stored at site

would need to be controlled to prevent potential impact on the environment.

Figure 3-1: Frequency and cumulative distribution of paste pH values for all samples

A distribution plot of the paste EC results is provided in Figure 3-2. About 2% of the samples had

paste EC values in excess of 1000 μS/cm. Of those samples with paste EC values greater than

1000 μS/cm five samples were mafic, two hydrated and one was shale.

The generally limited quantities of soluble salts present in the samples suggest that initial flushing

will not affect water quality significantly.

Figure 3-2: Frequency and cumulative distribution of paste EC values for all samples

3.1.2 Sulphur distribution

The distribution and cumulative distribution of total sulphur content for all are presented in

Figure 3-3. Table 3-2 and Table 3-3 provide a breakdown of the distribution of sulphur content by

deposit and domain.

Ninety one percent of the samples had a total sulphur content of less than 0.1 wt%.

Although about one third of all the waste would originate from the Madoonga deposit, the results

suggests that about 94% of the sulphur would be present in the Madoonga waste rock. This is in

part due to the shale and hydrated material occurring only at the Madoonga deposit. SHL and

HYD material are the domains with the highest average sulphur contents. At Madoonga, 70% of

the sulphur is in the shale and a further 16% is in the hydrated material.

The mass weighted average sulphur content in Madoonga waste is estimated to be about 0.36% and

that in the Beebyn waste rock is estimated to be about 0.012%.

The shale at Madoonga had the highest recorded, highest average and highest median sulphur

contents of 23.8%, 2.02% and 0.39% respectively and is considered to be the most variable

domain. In contrast, the total sulphur in Beebyn waste ranged up to only 0.36% for all samples

analysed.

The maximum total sulphur contents of the mineralised rock for Madoonga and Beebyn samples

were 0.18% and 0.19% respectively. The average mass weighted sulphur contents were 0.066%

and 0.012% for Madoonga and Beebyn samples respectively.

3.1.3 Acid neutralising capacity

The acid neutralisation capacity or potential (NP) is determined by reacting the sample with excess

acid (generally to a pH of less than 2) and then determining the acid consumed. Excess acid

addition depresses the pH to low values which results in both carbonate and silicate minerals

reacting. During high rates of acid generation only the carbonate minerals (predominantly calcium

and magnesium carbonates) react sufficiently rapidly to neutralise the acidity and maintain neutral

pH conditions. Therefore, the carbonate NP equivalent (CarbNP) was calculated from the

inorganic carbon content of each sample to provide an indication of the carbonate mineral content.

While recognising that not all carbonate minerals react to neutralise acidity (e.g. iron-bearing

carbonates such as siderite can be less effective neutralisers), using inorganic carbon content to

infer CarbNP is a reasonable first step to assess the readily available neutralisation capacity.

The average NP results for each domain are summarised in Table 3-4. The table also provides the

corresponding average CarbNP and the ratio of average CarbNP to average NP for each unit

(expressed as a percentage). For samples where the CarbNP exceeds the NP (CarbNP/NP > 100%)

it should be expected that CarbNP in excess of the NP would not be available to neutralise acidity.

Note: N= number of samples.

The results indicate that some domains have little neutralisation potential and therefore would not

be expected to provide significant buffering capacity. The units include the DID, FEL, HYD, and

high alumina mineralised (O_Al).

Waste types with significant NP included the magnetite (MAG) and SHL. However, the magnetite

unit would represent less than 1% of the total rock mass and therefore does not provide significant

overall NP. Mafic material has little carbonate neutralising capacity; therefore the majority of the

NP may not be readily available to buffer pH within a neutral pH range.

The calculated CarbNP values for BIF, HYD, MAG and SHL are greater than the respective NP

values. Thus a significant fraction of the measured total inorganic carbon is not present as

neutralising carbonates.

Mineralised ORE and high silica mineralised (O_SI) samples had an average NP of 9 and 12 kg

(H2SO4)/t equivalent with similar average CarbNP values of 6 and 14 kg(H2SO4)/t respectively.

3.1.4 Acid buffering characteristics

Eighteen samples representing a range of NP and CarbNP values were selected for acid buffering

characteristic curve testing. The complete results are provided in Appendix 11. The results of

seven samples are presented graphically in Figure 3-4 and the numerical results for all samples are

summarised in Table 3-5.

As shown in the figure, the pH of one of the samples (A13059) commenced at a pH of less than 6.

This is consistent with either an inorganic carbon content below detection (i.e. no carbonate

minerals and therefore provide no pH buffering capacity) or carbonate minerals that do not

contribute to circum neutral buffering. The remainder of the samples all commenced at a pH

above 6, were buffered in the neutral pH range for different acid additions and then decreased to

acidic pH values. This is typical of carbonate mineral buffering. The variation amongst the

different samples reflects differences in initial carbonate mineral content and possibly mineral

composition (e.g. calcite, dolomite, siderite etc.).

The curves were used to estimate the NP equivalency (i.e. NP equivalent to acid that had been

consumed) to a pH endpoint of 6 (for carbonate phases) and 4.5 to infer the availability of the NP

and the CarbNP. These results are shown in Table 3-5.

Significantly, the ABCC results indicated that not all of the carbonate minerals are available for

acid neutralisation at a pH 6 endpoint. Since only calcite and dolomite will react to buffer the pH

to above a value of 6, the carbonates that have reacted to that point are indicative of the available

CarbNP that would neutralise acidity. The difference between the pH endpoint acid consumption

and the inferred CarbNP represents carbonate minerals that would not react (e.g. siderite as

identified in the mineralogical analysis) to buffer the pH to circum neutral conditions.

In summary, the acid buffering characteristics curves indicate that both the NP and the CarbNP

lead to overestimation of the neutralisation potential available to buffer the pH to above 6 (i.e. to

prevent the onset of acid generating conditions.).

3.1.5 Net acid generation

The NAG tests are intended to provide a direct measure of the acid that may be generated by a

sample by oxidizing the sulphide minerals with a strong oxidant. The acidity generated is then

neutralised directly by the sample and the net acid generated is measured by titration with a strong

alkali. The results are summarised in Table 3-6 for both the Madoonga and Beebyn deposits. The

NAG test was conducted on 196 samples.

Overall, 9% of the samples had a NAG pH of less than 4.5 and would be considered net acid

generating. The NAG pH of 58% of the samples was above pH 6.0 and would be considered

non-acid forming (NAF). The NAG pH of the balance of the samples (33%) fell between

4.5 and 6.

The table shows for each domain the number of samples tested, the percentage of samples that

returned a NAG pH below 4.5, the percentage of samples that returned a NAG pH between 4.5 and

6, and the average NAG at pH values of 4.5 and 7. The last column shows the ratio of the NAG at

pH 7 to that at pH 4.5.

Waste rock domains that had no NAG pH values below 4.5 included the FEL unit. The

mineralised domains that had no NAG pH values below 4.5 included the ORE and the O_Si.

Domains that had no NAG pH values below 4.5 would be considered non acid forming. Although

caution is required in drawing conclusions for O_Si as only two samples were characterised. For

this domain further characterisation is necessary before a conclusion can be drawn. The large

proportion of samples that were buffered to a pH in excess of 6 within the remainder of the units

suggests that sufficient excess reactive neutralisation potential is available to maintain net pH

conditions.

The SHL would be considered most reactive as approximately 32% of the samples returned a NAG

pH value of less than 4.5, and as such would have the highest potential to generate acid. For those

samples found to be net acid generating, the average net acid generation potential was about 36 kg

(H2SO4)/t (Note that the test does not indicate the excess neutralisation potential for samples that

are non-acid forming and therefore cannot be used to infer the average net acid generation

properties of the lithological unit as a whole.)

Table 3-7 presents the total mass of each domain that would be waste rock, the fraction of the

waste rock in each domain expressed as a percentage and the percentage contribution to the total

mass by each domain that may be acid generating.

The average NAG at pH 7 of the MAF, BIF and DID ranged between 0.7 and 1.0 kg (H2SO4)/t.

The average values for HYD and SHL were 7.9 and 36.1 kg (H2SO4)/t. This suggests that some

portion of the waste could be net acid generating. Further analysis is required to evaluate the

overall potential for acid generation.

In the NAG measurement, titration to pH 4.5 generally accounts for free acid (H2SO4) and ferric

iron generated during the oxidation of sulphide minerals (that has not been neutralized by the

contained NP). Titration from pH 4.5 to pH 7 generally accounts for acidity associated with some

metals, such as copper, that are soluble at pH 4.5 but practically insoluble at pH 7. Acidity

attributed to un-oxidised ferrous iron will also be accounted for in the titration up to pH 7 (ferrous

iron remains soluble at pH 4.5; however oxidation to ferric by atmospheric oxygen accelerates as

the pH increases).

The ratio of acidity for the two titrations (i.e. pH4.5:pH7) may be used to infer whether or not the

acidity due to metal ions (other than ferric iron) is significant. Where the ratio is one, there is no

additional acidity, but the greater the ratio the larger the contribution from metals other than ferric

iron. Where available, the ratio ranged from 1.2 to 135, suggesting that other dissolved metals are

being released when acidic conditions develop. These metals will be identified as part of the

kinetic testing programme as described in a later section.

A plot of NAGpH as a function of total sulphur content is presented in Figure 3-5. (Note the scale

has been adjusted to exclude high S content samples so that a better resolution could be obtained

for the majority of the samples.) The results indicate a general trend of decreasing NAGpH with

increasing sulphur content. Only five samples with total sulphur content of less than 0.1% had a

NAG pH of less than 4.5; this represents about 3% of samples with a sulphur content of less than

0.1%. Therefore adopting a criterion of 0.1% as a cut-off grade for non acid forming materials

would lead to a potential misclassification of about 3% of the samples. Considering the low

sulphur content, (i.e. maximum potentials for acid generation are low, less than 3 kgH2SO4/t)

sufficient excess neutralisation capacity would be expected to be available to neutralise any local

acid generation that could result. This level of misclassification is considered acceptable. Thus, it

may be appropriate to assume that samples with sulphur contents less than 0.1% are not net acid

generating.

3.1.6 Elemental analysis

Global Abundance Indices (GAI) values were used to identify elements that exceed normal crustal

abundances (values used for comparison are mean sediment).

For each domain the mass fraction of each element was averaged over all samples. The GAI values

in Table 3-8 were determined from the averages according to the method described in Appendix 2.

Cells were left blank in Table 3-8 and Appendices 8 and 9 where all samples had GAI values of

0 or less. Elements with GAI values of 3 or greater are generally considered to be significantly

enriched.

There was generally low enrichment of the major elements, with Fe enriched in 25 samples and Ca,

Mn and S only enriched in 1 sample (out of a total of 338). There was comparable trace element

mineralisation across the range of domains, with the exception of the FEL and magnetite domain,

which are the least mineralised.

Arsenic was enriched in the detrital, shale and ORE material. The BIF contained the largest

number of samples with higher iron contents.

3.1.7 Distilled Water Leach Extractions

Distilled water leach extraction tests were conducted on 51 samples to assess the readily soluble

elements in the samples. The results are summarised in Table 3-9 with the ANZECC guideline

values for watering of stock animals. All results are listed in Appendix 10.

While the leach extraction test results cannot be used to directly estimate the water quality that

would be released from the mine waste materials, the results can be used to identify solutes that

could potentially be released at significant concentrations. Therefore, the results are compared to

Australian and New Zealand Guidelines for Fresh and Marine Water Quality (ANZECC (2000))

only to identify solutes that potentially may be of significance. Elements that exceeded ANZECC

(2000) guideline values for human health or stock watering are shaded in Table 2-1.

For all elements the median concentration was less than the ANZECC guideline value and for all

but three elements (Fe, Ni, Se) the maximum concentration was less than the guideline value. For

Ni the maximum value exceeded the guideline value by 2% and for Se the exceedance was 50%.

The largest exceedance was for iron and for which the concentration was a factor of 10 greater than

the guideline value.

3.1.8 Mineralogical assessment

A mineralogical assessment was carried out by Pontifex and Associates (Pty) Ltd. A total of

45 drill core samples from seven drill holes were assessed by petrographic analysis of polished thin

sections, with 38 of the samples also assessed using integrating semi-quantitative XRD. There are

a number of limitations of the testing procedures, some of which are overcome by the use of both

XRD and petrographic analysis (for example the identification of non crystalline clays). Sulphides

were only detected in 12 samples by optical examination, due to the fine particle size and sparse

distribution.

Whole rock chemical assay of the samples were not available at the time of analysis and therefore

could not be used as part of the mineralogical assessment.

The mineralogical assessment was provided by Pontifex, 2008. The approximate abundance of

minerals is consolidated in Table 3-10. The table summarises the mineralogical phase only.

The results indicate:

Sulphide mineralisation is primarily pyrite (FeS2).

Carbonate minerals including siderite (FeCO3), dolomite (CaMgCO3) and calcite (CaCO3) were

present. Whilst the dolomite and calcite would be expected to react to neutralise acidity, the

rate of dissolution of dolomite can be slower than that of calcite. The dissolution of siderite

(FeCO3) will neither consume nor generate acidity. The presence of siderite is consistent with

the outcomes of the ABCC test results, and the comparison of the NP and CarbNP results.

Alumino-silicate minerals (such as chlorite), which are known to contribute towards the ANC in

the Sobek static test method, were identified in a number of samples. These minerals are slow

reacting and are generally only expected to contribute to neutralising capacity at low pH values

encountered after the onset of AMD.

3.1.9 Acid generation classification

3.1.9.1 Classification criteria

The samples were categorised generally in three classes depending on their potential to generate

acid as follows:

Potentially acid generating (PAF) where the static testing provides evidence of net acid

generation.

Non acid forming (NAF) for which the static testing provides evidence that the samples are net

acid consuming.

Uncertain (UC) for samples where evidence is less conclusive with respect to net acid

generation.

While in many cases the criteria for classification are site specific, generally accepted criteria have

been developed that usually provide reasonable accuracy with respect to net acid generation. The

criteria that have been adopted herein are based on methods described in the ARD Test Handbook

(AMIRA, 2002) and the net potential ratio (NPR) method described by Price (1997).

The NPR provides a measure of the proportions of acid neutralising capacity to acid potential:

NPR = NP/AP

Where AP is the acid generation potential expressed in kg H2SO4/tonne calculated as follows:

AP = S(S2-

) * 30.6

The NPR classifications and the criteria defining the classifications are shown in Table 3-11.

Table 3-11: NPR classification scheme

Classification NPR range

NAF NPR > 3

UC 1 < NPR < 3

PAF NPR < 1

The AMIRA classification system relies on the NAGpH, the net acid production potential (NAPP

expressed as kg H2SO4 /tonne), the NAG (pH 4.5), as well as the total organic carbon (TOC)

because organic carbon because hydrogen peroxide reacts with organic matter to produce organic

acids. The NAPP is determined as follows:

NAPP = AP - NP

Table 3-12 lists the AMIRA (2002) classifications and the criteria defining the classification.

UC(PAF, high TOC) PAF samples that are associated with high TOC content (>5 wt%). The high TOC content may have interfered with the NAG test results

UC(NAF) Samples with positive NAPP value but NAG pH values ≥4.5. Some of the sulphur is possibly present in these samples in non-pyritic forms

LC=low capacity; UC=uncertain; TOC=total organic carbon; NAG pH=pH measured during net acid generation test; TOC=total organic carbon.

The AP, NAPP, NPR values and sample classifications according to both systems are provided in

Appendix 12. The results are discussed below.

We have also adopted an overriding criterion based on the sulphur cut-off grade of 0.1% below

which net acid generation is not expected to occur.

3.1.9.2 Net potential ratio

A summary of the number of samples in each class is provided in Table 3-13. The results indicate

that about 59% of the samples are non acid forming (NAF) and about 18% of the samples could be

classified as potentially acid generating. The distribution of the NAF / PAF samples is not

dissimilar to that obtained for the NAG test results (Table 3-6).

As discussed before, a number of the samples contain very low sulphur content, and thus very low

overall potential for acid generation. However, if combined with a low NP value, an NPR of less

than three is calculated even though the overall potential for acid generation is negligible. The

sample distribution was reassessed by reclassifying samples that have a sulphur content of less than

0.2% as NAF. The results are included in Table 3-13 and suggest that the fraction of the waste

samples that may be potentially acid generating could be as low as 4%.

Note: N=number of samples

As discussed previously, not all of the neutralisation potential may be available to buffer the pH

within the near neutral pH range. Sample classification was revisited after assigning neutralisation

potential to a value equal to the minimum of the NP and the CarbNP values.

The results are shown in Table 3-14 for all samples combined and Table 3-15 for only waste

samples. Overall, when using a minimum NP estimate, the percentage of samples classified as

PAF increases, whilst those classed as NAF decreases. However, when low sulphur contents are

taken into account, uncertainty in NP has little effect on sample classification.

For Madoonga results suggest that:

83 to 90% of the waste (108 to 117 Mt) is NAF

10% of the waste (13 Mt) is PAF

up to 6% of the waste (8 Mt) is UC

banded iron formation (BIF), hydrated (HYD), mafic (MAF) and shale (SHL) will produce

waste that is PAF

76 to 100%mineralised materials were classed NAF

0 to 24% were classed as PAF.

The PAF mineralised material was ORE and O_SI

Mineralised material classed as PAF it had a low capacity to produce acid (< 6.1 kg(H2SO4)/t

For Beebyn results suggest that:

99% of the waste (230 to 232 Mt) is NAF

about 1% of the waste (2.5 Mt) is PAF

none of the waste would be classed as UC

the PAF waste is from the mafic domain (MAF)

all of the mineralised materials were NAF and 2% were PAF.

The PAF mineralised material was O_AL

Kinetic test results 3.2

3.2.1 Sample properties

Kinetic tests provide an indication of rates of oxidation, acid neutralisation and solute release and

can assist in identifying criteria that separate PAF materials from NAF materials. Samples were

selected to cover a wide range of sulphur contents, along with samples classified as NAF, UC and

PAF.

Properties of samples selected for kinetic testing are shown in Table 3-19. The acid producing and

acid neutralising capacities of kinetically tested samples are also represented in Figure 3-6 together

with those of all other samples submitted for static test work. The kinetically tested samples are

highlighted in yellow squares.

Four samples selected from the Round A samples were tested in columns for 16 weeks in 2009.

These samples were classed as PAF based on static testing but had low total sulphur contents

ranging between 0.02 and 0.07 wt% S. The four samples were A13017, A13019, A13035 and

A13050. The testing of these samples was stopped after 16 weeks.

Another nine samples were selected from Round B samples. These samples were tested during

2010 over a period of 45 weeks. The columns were still operating at the time of preparation of this

report.

Two of the nine samples A13017 and ADML_1B_003 which are clearly non-acid forming due to

the low sulphur content and high NP and were selected to assess the potential of solute release from

net neutral samples.

Some sample names contain the prefix ADML_1B. For convenience the prefix will be omitted

when referring to the samples in the following text. For example ADML_1B_003 will be referred

to as 003.

3.2.2 Results and discussion

A summary of findings arising from kinetic testing is provided in the following sections. The

complete results together with plots of selected parameters are presented in Appendix 13.

3.2.2.1 Acid generation and neutralisation

The oxidation of sulphides produces reaction products that include sulphates and acidity. Where

the acid is not neutralised the pH of the column leachate decreases. Sulphate minerals may be

present in the sample material prior to starting column operation, possibly having formed as a result

of previous oxidation of sulphides.

The leachate pH values for consecutive leach cycles are illustrated in Figure 3-7 and Figure 3-8.

The time-series plots show that leachates from nine samples remained in the near neutral pH range,

indicative of carbonate mineral buffered pH conditions. In addition, the sulphate to (calcium

+ magnesium) molar ratio remained at or below a value of one (see plots provided in Appendix 14),

consistent with carbonate-based neutralisation of acid generated from sulphide oxidation.

Leachates from four samples were acidic at week 45 (Samples 249, 137, 280 and A13059). All

four samples were classed as PAF by static testing. Of the 13 samples kinetically tested these

samples had four of the five largest total S contents.

With respect to the four tests that have given acidic leachate, the following comments can be made:

Two of the samples produced long-term average leachate pH less than 3. In both cases, the

leachate was acidic immediately (by Week 2).

Two samples produced long-term average leachate pH around 4.3. In one of these samples, the

pH of early leachates was near-neutral, then plateaued at pH 5 before settling at the long-term

average value around Week 31.

The lowest total sulphur content of a material that had produced acidic effluent was 0.36 wt%

The higher sulphate concentrations in the early leachates probably reflect leaching of pre-existing

readily soluble sulphate from the sample. The longer term sulphate release is more likely to reflect

sulphate released by sulphide oxidation taking place during the test.

Figure 3-9: Consecutive sulphate concentration profiles for kinetic tests

Figure 3-10: Consecutive sulphate concentration profiles for kinetic tests

Solute concentrations in column leachates during the last few weeks of column operation were used

to calculate acid production and acid neutralisation rates. The rates are presented in Table 3-20.

For some samples the estimated rates of acid production may be overestimates as the sulphate

concentrations were decreasing in the last few weeks or were below the detection limit.

Estimates of the time to deplete the remaining acid potential and neutralisation potentials are also

reported in Table 3-20. For the neutral columns 064, 110 and 243 the neutralising potential was

predicted to be depleted within 1 to 9 years. Assuming that acid continues to be produced the

leachates would then become acidic.

It was estimated that the leachate from column 003 would remain neutral for about 200 years.

For columns A13019, A13035 and A13050 the neutralising potential was predicted to be depleted

before the acid potential. However, for these columns the total S content was less than 0.1 wt% S.

As will be discussed in Section 4.2, for these low sulphur contents there is reason to expect that the

columns will not become acidic.

Kinetic columns provide measurements of rates of acid production and acid neutralisation of waste

material under laboratory conditions. The laboratory measured rates may differ from field rates

due to a number of factors. One of these factors is the difference between the particle size

distribution of samples placed in columns and the particle size distribution of waste in a waste rock

dump or stockpile. This and other factors will be taken into consideration when using column-

derived data to estimate acid production rates applicable to waste rock dumps.

3.2.2.2 Solute leachability

Table 3-21 summarises calculated average solute release rates calculated from data obtained during

the last few weeks of column operation.

In general, higher element release rates coincide with acidic effluents. For example, for sample

280 (a shale), which had a pH of 2.8, the Al and As release rates were 16.6 and 0.11 mg/kg/wk.

Whereas for sample 027, at pH 6.6, the release rates for the same metals were 0.005 and

0.00048 mg/kg/wk.

The evolution of As in column leachates is presented in Figure 3-11 and Figure 3-12. Results for all

columns and all metals are presented in Appendix 13.

As discussed in Section 3.2.2.1 rates measured for laboratory samples may differ from rates for

reactions under field conditions. This should be considered when using the laboratory measured

rates, for example, in water quality predictions.

Waste Rock Management 4.

Simple classification scheme 4.1

A simple classification scheme is required for developing a block model of waste types and for classing

materials during mining. Materials classed as PAF under the simple scheme would be segregated during

mining and managed to control the development and impact of acid and metalliferous drainage.

Static test results conducted in 2009 were used to classify the waste and ore samples as potentially acid

forming (PAF), non-acid forming (NAF) or uncertain (UC). The NPR classification scheme was used.

This classification scheme is an internationally accepted method of screening the potential of materials to

be PAF. However, the classification scheme requires the measurement of the acid neutralising capacity

and the acid generating potential.

The acid generating potential can be estimated from the total S content, which can be readily and

routinely measured as part of the resource definition work. The ANC cannot be estimated reliably using

parameters routinely included in resource definition work. Measurement of ANC is potentially more time

consuming than determination of the total S content.

To provide a simple classification scheme, a scheme based on total sulphur content is proposed. A

fundamental assumption is that samples with total S contents less than a threshold value Sc are non-acid

forming and those with total S greater than Sc are potentially acid forming. Figure 4-1 shows the new

simple classification system projected onto the previous classification system. Some low S samples,

previously classed as PAF would now be classed as NAF (Region C) – however, as discussed earlier

(Section 3.1.5), the acid potential associated with these samples is extremely low.

Some samples previously classed as NAF will be classed as PAF (Region B) because their total S content

is greater than Sc. An outcome of this is that a mass of material previously classed as NAF is destined to

be managed as PAF material. However, as will be shown, relatively small masses of material are

involved.

As the value of Sc is increased the mass of material classed and managed as PAF decreases. However,

there is a risk that a portion of the material with a total S content less than Sc is potentially acid forming.

Thus, as Sc increases the risk of not managing potentially acid forming material appropriately increases.

Figure 4-1: Distribution of samples within a simple classification scheme

Selection of Sc for Weld Range 4.2

Static testing of Weld Range materials suggested that some samples with low total S content are

potentially acid forming. Kinetic testing included PAF-classed samples with total S contents ranging from

0.10 to 23.8 wt%. As of Week 45, only those samples with total S ≥ 0.36 wt% had produced acidic

effluent. Current data thus places an upper bound on the Sc value of 0.36 wt% S. In the case of the PAF

columns with lower total S, it remains possible that acid leachates could be produced. Thus it remains

possible that a Sc should be set to at a value less than 0.36 wt% S.

Only about 3% of samples with total S contents less than 0.1 wt% had NAGpH values less than 4.5 and

the majority of samples had circum neutral of alkaline NAGpH values (Section 3.1.5). This indicates that

0.1 wt% S may be a suitable to value for Sc.

SRK recommend that a lower Sc threshold is used, 0.1 wt% S. This threshold is known to be applied

elsewhere within the Pilbara to differentiate wastes with very low risk of generating ADML. Also, an

International Kinetic Database reported by Morin et al. (1995) showed that no incidences of acidic

leachate were documented for samples with initial sulphur content less than 0.1% (30 such samples were

included, and none generated leachate of pH less than 5).

While a lower value for Sc decreases the risk of not identifying and not managing PAF material it also

results in a larger volume of material being treated as PAF waste. However, Section 4.3 shows that the

increase in the mass of waste treated as NAF is relatively small as for a range of Sc values between 0.1

and 0.25.

GARV/CHAP SMM004_ENV_RP_2_Rev1.docx March 2011

It may be possible to obtain data that supports increasing the value of Sc (and decreasing the mass of

waste classed PAF) from the samples that were leach tested for 45 weeks. Sample material removed from

the columns would be submitted for static testing to determine the quantity of oxidisable sulphur

remaining in each column sample.

The test would be conducted by collecting a subsample from each column of material that has not

produced acidic leachate. Each subsample would then be split and one portion (A) analysed to determine

the total S and sulphate S content. The second portion (B) would be reacted with peroxide to oxidise

available sulphides to sulphates. The quantity of sulphates would be determined.

If the quantity of sulphates determined for the oxidised portion (portion B) does not exceed the quantity

of sulphates in the unreacted portion (portion A) then it can be concluded that there are no sulphides in

the materials that are readily oxidised and could contribute to acid production. Where this is the case it is

unlikely that the samples will produce acidic leachate in the future.

It is expected that results would be available from a commercial laboratory about two to three weeks after

the receipt of samples and that the tests would be relatively inexpensive (less than $2500).

SRK therefore recommends that the operation of columns is stopped and the samples are collected from

all neutral columns that were operating to week 45 and sent to a commercial laboratory to measure the

quantity of remaining oxidisable sulphide.

Mass Dependence on Sulphur Threshold 4.3

For six values of Sc, Table 4-1 presents, estimates for the Madoonga deposit of the:

1. Mass of waste rock that would be classed as PAF under the simple scheme (regions B+D; Figure 4-1)

2. Mass of waste rock that would be classed as PAF under the simple scheme and was classed as NAF

under the NPR scheme (region B; Figure 4-1).

3. Mass of waste rock classed as PAF under the simple scheme and as PAF or UC under the NPR

scheme (region C; Figure 4-1).

The mass of waste classed as PAF at Madoonga under the simple scheme is also shown in Figure 4-2 for

several values of Sc. The figure shows that the mass of waste that would be classed as PAF decreases as

Sc increases. Note that the mass of PAF waste decreases by only a small fraction for Sc values between

0.1 and 0.25 wt% S.

Table 4-2 and Figure 4-3 present similar data for Beebyn.

The masses of waste that would be classed as PAF using a total S cut-off grade of 0.1 wt% S are:

Madoonga - 21 Mt

Beebyn - 3.3 Mt

The above estimates of the masses of PAF material are based on the PFS pit design. The masses may

change as a result of the review of the distribution of PAF material within the BFS pit shell.

A water quality assessment will be conducted to assess the potential impact of the PAF wastes and

stockpiles on water contacting the dumps and stockpiles. It is possible that the assessment will find that

some PAF material will not significantly impact water quality and that the mass of material to be

managed to control acid drainage and metalliferous leaching is less than stated above

SRK recommends that Sinosteel plan to manage approximately 21 Mt of PAF waste at Madoonga and 3.3

Mt of PAF waste at Beebyn pending the findings of a) the review of the distribution of PAF material

within the BFS pit shell and b) a water quality assessment.

Management Strategies 4.4

Current indications are that a small proportion of the waste rock and mineralised material could be PAF.

The impact of the PAF material on water quality has not yet been evaluated. An evaluation of this type is

proposed in the next section.

In the event that a water quality assessment determines that it is necessary to manage PAF material

several options are available including i) covering or isolating the PAF waste with NAF materials to

reduce the quantity of water contacting the PAF waste (Figure 4-4), ii) co-mingling or blending the PAF

waste with NAF waste that has excess neutralisation capacity and iii) segregating and placing the PAF

waste where acid generation can easily be controlled or prevented (e.g. backfilling to the open pit below

the long term water table).

For option i) NAF material would be placed at the base of the dump to reduce contact between PAF waste

and the water that flows at the interface of the waste (base of the dump) and the original ground surface.

PAF material would then be covered with NAF material, graded to enhance runoff and compacted to limit

infiltration, thus reducing the contact between incident rain and PAF waste. Depending on the properties

of the NAF material (e.g. thickness of layer, sulphide mineral content, particle size distribution,

weathering properties etc.), it may also serve to reduce the availability of oxygen to the PAF material thus

reducing the rate of oxidation. This management strategy may be used during mining when the pit is

being constructed and PAF material must be removed from the pit for efficient mining.

Blending PAF material with material containing excess neutralisation capacity generally requires tight

controls on blending ratios and is operationally complex to implement. Success has been limited in the

past due to the fact that it is not always possible to achieve well mixed conditions during placement and

maintain contact between the acid produce and neutralising materials in the longer term. Based on current

information this option would not be recommended.

In-pit disposal could limit to very low levels, or even preclude, oxidation of sulphides if the PAF waste is

placed below the long term steady water level in the pit. Because of the demonstrated performance on

controlling oxidation and acid generation, placement of PAF materials below the water table within the

open pit is believed to be the most effective option for managing PAF waste rock at the site.

The relative levels (RL) of the groundwater prior to digging of the pits at Madoonga and Beebyn were RL

481 and RL 495 m respectively. Preliminary hydrogeology investigations indicate that 25 years after

mining has finished the water level would have risen to RL 430 and RL 480 m at Madoonga and Beebyn

respectively. These levels are below the original groundwater level. Thus, there would be no net

groundwater recharge from the pits for at least 25 years.

Waste placed at the base of the pit would be flooded, reducing the diffusive supply of oxygen to the waste

by about four orders of magnitude and slowing the rate of oxidation greatly. A schematic arrangement of

the waste in the pit is shown in Figure 4-5. Benign or NAF material placed over the PAF material would

reduce the evaporative loss of rain and rising groundwater prior to flooding of the pit as a result of the

recovery of the groundwater levels. The importance of the NAF layer in reducing evaporation increases in

the event that the balance of recharge and evaporation is such that the water level in the pit does not rise

far above the pit floor (Figure 4-6).

Current and Future Work 5.

Estimates of the quantities of PAF material in the Madoonga and Beebyn pits in this report are based on

the PFS pit shell. The current (BFS) pit is larger than the PFS pit shell and consequently more waste will

be produced. Thus there is a need to determine how well samples collected from within the PFS pit shell

represent the rock types within the BFS pit shell.

Materials outside the PFS pit shell and inside the BFS (VI) pit shell were not sampled to any significant

degree. Therefore these materials have not been classified as either PAF or NAF. Available information

should be reviewed to determine the distribution of sulphur within these materials

Quantities of PAF material, rates of acid production and neutralisation and rates of solute release have

been estimated from kinetic testing of waste and stockpile material. These quantities are determined in

part for use in assessing the impact of mined materials on the quality of water that they contact. One

possible outcome of a water quality assessment is the need to manage the PAF waste to reduce the

potential impact on waters.

Current and future recommended work includes:

a) The current review of the distribution of PAF material within the BFS pit shell

b) An assessment of the quality of water that contacts the waste and mineralised material.

PAF material - mass and distribution and schedule 5.1

Available drillhole logs, the geological model and the block model will be reviewed to estimate the mass

and spatial distribution of PAF material (based on distribution of sulphur within the materials).

The accuracy of the estimates will depend on the both the accuracy of the classification of the wastes as

PAF and the quantity and locations of relevant geological data obtained from drillhole sampling.

At Weld Range the drillholes collars are typically located to the south of the mineralised zone and

drillholes dip to the north and terminate near the mineralised zone. Thus, wastes in the northern side of

the pit are sparsely sampled. SRK understands there is no block modelling to the north. In the absence of

drillhole and block model data, the geological model will be used to infer masses of the various

lithologies and alteration types. Simulation of sulphur grades in the northern waste may be undertaken if

appropriate.

The objective will be to assign a classification (PAF or not PAF) to waste material at the same spatial

resolution as the block model units. Any assumptions made regarding the spatial distribution of the

geological and the geochemical characteristics will be reported.

The movement of pit waste will then be reported as per the current mining schedule. The time steps in the

scheduling will be one year. The spatial locations of the PAF waste blocks will be tracked and the likely

spatial locations within proposed waste dumps recorded.

Water Quality Assessment 5.2

The findings of the static and kinetic testing of the previous section show that there is potential for acid

drainage or metal leaching being produced from some materials in waste rock dumps, pit walls or

stockpiles at Weld Range. It is necessary therefore to assess how water quality might be affected.

A water quality assessment would include:

1. Development of a model to predict water quality from waste rock dumps. It will be necessary to make

assumptions at this stage. For example, the distribution of oxidation and neutralising rates in the

dump will be assumed.

2. Prediction of contaminant release rates from the dump for each lithological unit where possible.

3. Assessment of potential oxygen transport constraints because the contaminant release rate is

dependent on the oxidation rate.

4. Prediction of the potential quality of water seeping from the dump by assessing the rainfall and net

infiltration, seepage evolution through the different lithologies in the dump and by assuming flow

paths through the dump. The geochemical modelling programme PHREEQC will be used where

appropriate.

5. Review of water receptors. Whilst the seepage discharged from the dump may be of poor quality,

there may not be any receptors that will be affected by it both from a negative impact and legal

perspective. With the assistance of Sinosteel Midwest Management possible receptors will be

identified and the potential implications of the seepage on these will be assessed and conceptual

strategies to minimise the impacts will be identified (e.g. reducing seepage volume and impact by

limiting oxygen and water inflow).

6. Identification of strategies for management of waste rock and pit walls. An assessment of the

implications of implementing the various proposed strategies will be conducted taking into account

mine planning, groundwater and surface water conditions and requirements.

Conclusions and recommendations 6.

Conclusions 6.1

Some materials contain stored acidity and at the time of mining they could have potential to release

acid. These materials include a significant proportion of the detrital (DID) and smaller proportions

of the felsic (FEL), banded iron formation, hydrated and mafic wastes. Similarly, small proportions

of the three mineralised domains (ORE, O_AL, O_SI) could also be marginally net acid generating.

Generally there are limited quantities of soluble salts present, which indicate that flushing of the

mined materials prior to oxidation will not affect the solute content of water significantly.

The majority of waste rock and mineralised materials are expected to have low total sulphur

contents. Of the 339 samples subjected to static tests, 91% of the samples had a total sulphur

content of less than 0.1 wt%.

Non neutralising carbonates are present and therefore the minimum of the neutralising potential NP

and CarbNP was the most appropriate measure of the neutralising capacity available for the

majority of samples. A small number of acid buffering characteristic tests indicated that the actual

neutralising potential for some material may be less than the minimum of the NP and CarbNP.

Static and kinetic leach testing indicates that solute release rates are generally low under neutral

conditions and can increase under acidic conditions.

The masses of PAF, NAF and UC waste and mineralised material were estimated using

conventional static testing and classification methods and are presented in the tables below for the

Madoonga and Beebyn deposits.

Mineralised Mass % 76 to 100 0 to 24 0

ORE, O_SI Mass (Mt) 38 to 50 0 to 12 0

NAF – non-acid forming. PAF – potentially acid forming, UC – uncertain (screening tests do not clearly identify sample as PAF or NAF)

Beebyn

Waste Mass % 99 to 100 0 0 to 1

MAF Mass (Mt) 231 to 233 0 0 to 2.5

Mineralised Mass % 98 to 100 0 0 to 2

O_Al Mass (Mt) 47.5 to 48.4 0 0.9

At least some of the materials classed as PAF by static tests did produce acidic effluent in column

tests, verifying their potential to produce acidic drainage in waste dumps. The acid leachates were

produced in column tests involving materials with relatively high total S contents (≥ 0.36 wt%).

It is not clear from investigations on samples from Weld Range whether PAF-classed materials

with lower total S contents will become acidic.

In principal a simple scheme can be established for classifying samples as PAF or NAF based

solely on the total S content of samples. However, for the scheme to be of practical value, it is

necessary to establish a threshold total S content (Sc) below which waste is unlikely to become

acidic in the long term. (In this simple classification scheme material classed as UC in the

conventional schemes is conservatively classed as PAF.)

The lower the value of Sc the larger the volume of material classed as PAF.

Data for Weld Range samples suggests that Sc may lie between 0.1 and 0.36 wt% S.

Based on the lower bound Sc value of 0.1 wt% S and the PSF pit shell design the mass of material

that would be classed as PAF at:

a) Madoonga would be about 21 Mt

b) Beebyn would be about 3.3 Mt.

The mass of waste classed as PAF varies little for Sc values in the range 0.1 to 0.25 wt% S.

Examples are given in the following table.

Sc (wt% S) Mass of Waste Classed as PAF (Mt)

Madoonga Beebyn

0.0 130.7 233.2

0.1 20.6 3.3

0.25 13.1 3.3

It may be possible to obtain data that supports using a larger value of Sc (and thereby reduce the

mass of waste classed PAF) from the samples that were leach tested for 45 weeks. To obtain

suitable data a sample of material would be removed from the columns and statically tested to

determine the quantity of oxidisable sulphur remaining in each column sample.

Recommendations 6.2

SRK recommends that:

1. That a simple scheme based on a threshold value of total sulphur content (Sc) is used for

classifying materials during mining. In the absence of further information on the acid

producing and acid neutralising capacity of materials the scheme would be as shown in

recommendations 2 and 3.

2. The value of Sc is taken as 0.1 wt% S.

3. Materials with:

a) Total S ≥ 0.1 wt% are classed as PAF and those with

b) Total S < 0.1 wt% are classed NAF.

4. An assessment is undertaken to determine whether use of a larger value of Sc can be justified.

A larger value of Sc would result in a smaller volume of waste being classified PAF. An

approach is presented in recommendation 5.

5. Operation of the long-term (45 week) kinetic columns should cease. Samples should be

obtained from those columns giving neutral leachate. These samples should be sent to a

commercial laboratory to measure the quantity of remaining oxidisable sulphide. The data

obtained will help determine whether a larger Sc can be used.

6. The current review of the quantity and distribution of PAF and NAF materials within the BFS

(VI) pit shell being is completed. Details are given in Section 5.1.

7. An assessment is undertaken of the potential quality of water that comes into contact the waste

and mineralised material. Details are given in Section 5.2.

STATIC TESTING METHODS AND GUIDELINES

Paste pH and Paste EC

Paste parameters provide an indication of the degree of weathering the material has experienced as

well as the availability of reactive mineral species and readily soluble salts. Generally, paste pH

values less than pH 5 are indicative of stored acidity (i.e. stored oxidation products) and net acid

generating conditions, whereas high paste pH values suggest the presence of reactive neutralising

minerals.

These characteristics reflect the potential of a sample to impact the quality of water contacting the

sample without the sample undergoing further chemical change/weathering. Such potential exists

whether the sample is classified as NAF, UC or PAF. A method consistent with the AMIRA

(2002) method was used.

Net Acid Producing Potential

The net acid producing potential (NAPP) is the theoretical balance between the capacity of the

sample to generate acid via the oxidation of sulphides and its capacity to neutralise any acid

formed. The maximum potential acidity (MPA) of the sample is calculated from the total sulphur

content, assuming that all sulphur is present as pyrite.

The acid neutralisation capacity (ANC) or neutralisation potential (NP) is measured by reacting the

sample with a known amount of low pH hydrochloric acid. After the pH has stabilized the sample

is back titrated with a base to determine the amount of acid that had been consumed by the sample,

which is assumed to represent the NP.

The NAPP is calculated as follows:

NAPP = MPA – NP (kg H2SO4/t)

Where MPA = 30.6 x S% and the sulphur content is expressed as weight percent (wt %).

The assumption that all sulphur in the sample is present as sulphide (pyrite) generally overestimates

the amount of acid generated, since sulphur will exist in other forms that are not acid generating

(e.g. as sulphate, elemental sulphur and non acid generating sulphides).

Net Acid Generation

Net acid generation (NAG) measures how a sample could behave under highly oxidising

conditions. The sample is contacted with the strong oxidant hydrogen peroxide. The peroxide

oxidises the sulphides contained in the sample which generates acid. Concurrently, neutralising

minerals that may be present consume all or part of the acid generated. Following a predetermined

contact time, the solution pH is recorded and the NAG acidity of the sample is quantified by

titration with a base (sodium hydroxide).

Acid Neutralising Capacity (ANC) and Carbonate Neutralising Potential (CarbNP)

The acid neutralisation capacity (ANC) or neutralisation potential (NP) is a measure of the role that

gangue minerals could play in neutralising acid generated during sulphide oxidation. The ANC

measurement is described above (see Net Acid Producing Potential). The neutralisation potential

of a sample can be sourced from both carbonate and silicate minerals. Calcium and magnesium

carbonates are the most important contributors for domains that generate acid at a high rate since

they are very reactive and readily neutralise acidity at a high rate. Some carbonate minerals, such

as iron and manganese carbonates, do not contribute to neutralisation. Other neutralising minerals

such as silicates react at low pH values and will only contribute to the neutralising capacity after

the leaching solution has become strongly acidic.

Page 71: Geochemical Characterisation of Weld Range Waste and ...€¦ · from the Sinosteel Midwest Corporation Weld Range Project. Overall Objective The overall objective was to determine

SRK Consulting Geochemical Characterisation of Waste and Mineralised Rock; Static and Kinetic Testing Appendix 2-2

GARV/CHAP/kami/dick SMM004_ENV_RP_2_Rev1.docx March 2011

The endpoint pH after the addition of HCl in the NP measurement is very low (typically between

pH values of 1 and 2) and leads to additional reactions that will occur only at a low pH

(i.e. neutralisation due to dissolution of the silicate minerals). The NP measurement may therefore

overestimate the neutralisation capacity that is available.

A more appropriate assessment of the NP that is available to maintain near neutral pH conditions is

to infer the proportion of NP that is sourced from the calcium and magnesium carbonate minerals

directly. The inorganic carbon content can be used to infer the carbonate mineral content and

estimate the carbonate neutralisation potential (CarbNP). Comparison of the CarbNP values with

the NP values can give an indication of the proportion of the neutralising capacity of the sample

that is due to the presence of carbonate minerals.

Acid Buffering Characteristic Curve

The ABCC test involves slow titration of a sample with acid while continuously monitoring pH.

This data provides an indication of what portion of the acid neutralising capacity (ANC) measured

in a sample is readily available for acid neutralisation (AMIRA, 2002).

Global Abundances

Bulk chemical assays were undertaken on all samples. The following elements were included in

the assays:

Major elements – Al, Ca, Fe, K, Mg, Mn, Na, P, S and Si; and

Minor elements – Ag, As, Au, B, Ba, Be, Bi, C, Cd, Co, Cr, Cu, F, Hg, Mo, Ni, Pb, Sb, Se, Sn,

Sr, Te, Th, Tl, U, V and Zn.

A direct comparison of the measured abundances of the elements was made with the average

abundance of elements in the Earth’s crust (Bowen, 1979). This provides the global abundance

index (GAI) of elements and indicates which elements are ‘enriched’ in the sample with respect to

the global average. The GAI is calculated using the following formula (Förstner, 1993):

GAI =

Abundance Average5.1

ionConcentrat Measuredlog 2Int

An example of GAI values is provided in the following table. In the table n is the ratio of the

measured abundance in the sample to the reference material abundance.

Ranges of the Ratio of the Measured Concentration to Average Abundance (n) and the Corresponding Global Abundance Index

n range GAI

1 < n < 3 0

3 ≤ n < 6 1

6 ≤ n < 12 2

12 ≤ n < 24 3

Zero or positive GAI values indicate enrichment of the element in the sample when compared to

average-crustal abundances. As a general rule, a GAI of 3 or higher signifies enrichment that

warrants further evaluation.

Leach Extraction Tests

A total of 250 g of sample and 750 mL of distilled water are placed in a 1000 mL container. The

mixture is gently agitated for 24 hours and allowed to stand for a minimum of three hours allowing

suspended material to settle. The supernatant is collected and submitted for multi-element analysis.

Kinetic Testing Procedure

A modified AMIRA procedure (AMIRA, 2002) was utilised with the principle differences relating

to the particle size at which the tests were completed and the flushing regime. The testing

procedure was as follows.

Each sample was coarse crushed (<10 mm) and placed in a large diameter Buchner filter lined with

filter paper to retain the solids. The rock sample was then subjected to a weekly rinsing and drying

cycle. Each week the sample was rinsed with about 1000 ml of deionised water. The water was

added to the top of the sample and allowed to drain under gravity and the leachate collected at the

base of Buchner filter and submitted for analysis as follows:

Weekly – pH, electrical conductivity (EC), sulphate, acidity and total alkalinity.

Every 3 to 4 weeks – Ag, Al, As, Ba, Be, Ca, Cd, Cl, Co, Cr, Cu, Fe, Hg, K, Mg, Mn, Mo, Na,

Ni, P, Pb, Sb, Se, Sn, Sr, Th, Tl, U, V and Zn.

Generally column leach tests that exhibit slow rates of reaction require a minimum operating time

of 40 to 50 weeks unless acidity conditions develop fully at an early stage of the test. The criteria

that may be considered to assess whether testing should be discontinued include:

pseudo steady state;

oxidation rates (i.e. acid generation rates) and neutralisation potential depletion rates together

with static test results indicate that net acid generating conditions are unlikely to develop, and

metal leachability is unlikely to change in the future; and

A good understanding of rates of oxidation and leaching has been developed based on the

available data.

General Comments

The analytical procedures used by the Environmental Division have been developed from established internationally recognized procedures such as those published by the USEPA, APHA, AS and NEPM. In house

developed procedures are employed in the absence of documented standards or by client request.

Where moisture determination has been performed, results are reported on a dry weight basis.

Where a reported less than (<) result is higher than the LOR, this may be due to primary sample extract/digestate dilution and/or insuffient sample for analysis.

Where the LOR of a reported result differs from standard LOR, this may be due to high moisture content, insufficient sample (reduced weight employed) or matrix interference.

When date(s) and/or time(s) are shown bracketed, these have been assumed by the laboratory for processing purposes. If the sampling time is displayed as 0:00 the information was not provided by client.

CAS Number = CAS registry number from database maintained by Chemical Abstracts Services. The Chemical Abstracts Service is a division of the American Chemical Society.

LOR = Limit of reporting

^ = This result is computed from individual analyte detections at or above the level of reporting

Key :

All results reported in mg/L and the pH under EA005, have been determined on a 1:3 soil to DI water leachate, tumbled end over end for 24 hours.l

EA011S (Sequential Net Acid Generation): Both samples were stopped after stage 1 as the NAG at pH 7 was <2 kg H2SO4/t.l

LCS recovery for Sulphate as SO4- Total (ED040T) fall outside Dynamic Control Limits. They are however within ALS Static Control Limits and hence deemed acceptable.l

General Comments

The analytical procedures used by the Environmental Division have been developed from established internationally recognized procedures such as those published by the USEPA, APHA, AS and NEPM. In house

developed procedures are employed in the absence of documented standards or by client request.

Where moisture determination has been performed, results are reported on a dry weight basis.

Where a reported less than (<) result is higher than the LOR, this may be due to primary sample extract/digestate dilution and/or insuffient sample for analysis.

Where the LOR of a reported result differs from standard LOR, this may be due to high moisture content, insufficient sample (reduced weight employed) or matrix interference.

When date(s) and/or time(s) are shown bracketed, these have been assumed by the laboratory for processing purposes. If the sampling time is displayed as 0:00 the information was not provided by client.

CAS Number = CAS registry number from database maintained by Chemical Abstracts Services. The Chemical Abstracts Service is a division of the American Chemical Society.

LOR = Limit of reporting

^ = This result is computed from individual analyte detections at or above the level of reporting

Key :

All leachate analytical results reported in mg/l have been determined on a 1:3 solid/water leach that has been tumbled end over end for 24 hours before analysis.l

ED045G (Chloride): LCS recovery falls outside Dynamic Control Limits. It is however within ALS Static Control Limits and hence deemed acceptable.l

LCS recovery for EG020A-W (Water Leachable Metals) fall outside Dynamic Control Limits for Antimony, Silver and Strontium. They are however within ALS Static Control Limits and

hence deemed acceptable. No further action is required.
