LAKE TORRENS PROJECTLAKE TORRENS PROJECT

IRON OXIDE-COPPER-GOLD-URANIUMTARGETS


IOCGIOCG--U Simplified Geological ModelU Simplified Geological Model

One theory for the formation of iron oxide copper gold-uranium deposits involves hot magmatic/ hydrothermal waters charged with dissolved Fe, Cu, Ag, Au, U and rare earth elements ascending upwards, mixing with cooler meteoric waters and precipitating iron oxides with associated gold, copper and uranium mineralsation. At Oylympic Dam these processes occurred beneath and within a large maar type volcanic system, leading to the development of a large variety of complex breccias and variably altered host rocks .


Australian Uranium ResourcesAustralian Uranium Resources

Olympic Dam is the largest uranium deposit in the world and contains 40% of the worlds known uranium resources. Most of Tasman's IOCG-U prospects are located within 40km of Olympic Dam .


Lake Torrens ProjectLake Torrens Project

• 7 IOCG-U targets/gravity anomalies identified within 30km of Olympic Dam (42% of world’s uranium resource)

• Hematite breccias intersected at Titan and Marathon South

• Only very limited drill testing to date• Follow up drilling in 2006

•Residual gravity image (128pass hanning residual of variable density Bouguer gravity)

•Assessment of the regional geophysical data together with a new interpretation of cover thickness in the Tasman project area has lead to the selection of a number of targets with the potential to host IOCG mineralisation (Atlas is a gabbroic body with Ni potential)

•All Tasman IOCG targets are either untested or only partly tested by drilling.

•The southwestern edge of the Torrens Hinge Zone is the heavy dashed black line.

Large magnetic and gravity anomaly at Titan showing limited extent of drilling to date.

Significant variations on alteration, chemistry, mineralisation and geology located in drilling.

Major portions of the system completed untested.

Heat flow mapping planned as a new technique to add to the understanding of the system.


Titan BrecciasTitan Breccias

Examples of the mineralised rocks from Titan:

TI6 core : 620.5m depth

Magnetite-sulphide breccia (vein); pyrite, chalcopyrite

1.8% Cu and 0.3ppm Au (for 620-621m interval)

TI2 core: 744.7m depth Haematite altered metarentite clasts in haematite matrix supported breccia


Marathon South Gravity and BrecciasMarathon South Gravity and Breccias

Marathon South residual gravity image showing location of the four diamond holes drilled to date.

Holes MS1 and MS3 intersected hematitic breccias (favourable host rocks for IOCG mineralisation) as shown in the drill core above.

Textures, alterations, leaching, brecciation and geophysical evidence suggest that Marathon South includes subvolcanic diatreme features typical of the types of systems considered responsible for Olympic Dam and Prominent Hill.

The large area of the geophysical feature has been barely touched by the four holes drilled to date.


Torrens Hinge Zone: MVT conceptTorrens Hinge Zone: MVT concept

Concept for the formation of Mississippi Valley style (MVT) limestone hosted lead-zinc mineralisation within Tasman’s lake Torrens tenements:

Inversion of the Adelaide Geosyncline during the Delamerian Orogeny lead to expulsion of ?mineralised brines from Adelaidian sediments, combined with fluids released by basin dewatering and diagenesis.

Reactivated faults forming the Torrens Hinge Zone controlled fluid flow & channelled metal carrying solutions into the basal Andamooka Limestone

where MVT style mineralisation may have formed.

Andamooka Limestone is predicted to lie from near surface (10-60m below surface) to a depth of up to 200m below surface.

Innovative exploration technique is Soil Desorption Pyrolysis – a true soil gas tool that looks at a broad range of gaseous species emitted from mineralisation

– MVT is particularly well suited to this approach because hydrocarbons released from the basin are very commonly assocaited with MVT mineralistion & are particularly easy to detect using the SDP approach.

GA seismic data has clearly identified the faulting & detailed aeromagnetic data reveals the trace of these faults – allowing focussed sampling for the SDP work


Torrens Hinge Prospect: SDP ResultsTorrens Hinge Prospect: SDP Results

An SDP soil survey has defined two priority targets above the intepreted position of the major basin margin fault. SDP is a relatively new geochemical technique that involves "fingerprinting" of mineral deposits types with a high degree of confidence. SDP measures trace amounts of volatile compounds that are adsorbed onto clay-sized particles in soil. Volatiles such as light hydrocarbons, halogens and sulphur compounds migrate readily through thick columns of rock. Most of these compounds reach the surface and are lost to the atmosphere. A tiny proportion of the gases present just below ground level are adsorbed onto the surface of soil particles. This material is sampled and the gas contents measured. Rocks degas constantly due to burial, diagenesis, metamorphism and interaction with groundwater. However, ore deposits and the fluids that form them are chemically very different from their surroundings, and are frequently also associated with high temperatures. The net result is that the gas flux above a buried ore deposit is quite distinct from the regional background signal.


CENTRAL GAWLER PROJECTCENTRAL GAWLER PROJECT

PALAEOCHANNEL - HOSTED URANIUM TARGETS


Central Gawler Palaeochannels: Facies Model for Central Gawler Palaeochannels: Facies Model for Uranium MineralisationUranium Mineralisation

Simplified after Hou, Frakes & Alley, PIRSA 2001

Uranium is dissolved from surrounding host rocks by acid oxidising waters and percolates downstream within buried sandy drainage channels (palaeochannels) where it is precipitated under reducing conditions associated with decaying organic material in marshy environments adjoining the estuary channel.


Tasman Gawler Craton Uranium ProspectsTasman Gawler Craton Uranium Prospects

Tasman’s Gawler Craton tenements cover portions of at least two major uranium prospective palaeochannel systems. The Warrior uranium deposit discovered during the last uranium exploration boom in the early 1980’s lies on an adjacent palaeochannel to the east of Tasman’s Wynbring project.


Wynbring

• +40km of palaeochannel• Warrior uranium deposit within adjacent palaeochannel

15km to SE • Significant radiometric anomalies in 1980’s drilling at

shallow depth at southern end of Tasman EL• Anomalies associated with carbonaceous/pyritic sediments

& lignites at redox interface as at Warrior • 95% of palaeochannel untested• Drilling in 2006


Wynbring Palaeochannel InterpretationWynbring Palaeochannel Interpretation

Previous drilling by PNC exploration in the 1980’s defined the Wynbring palaeochannel to the south of Tasman’s EL 3306. Limited drilling by PNC in the southern portion of Tasman’s EL recorded anomalous radiometric responses in six holes. In 2005 Tasman flew a HoistEM electromagnetic survey to aid definition of the northern continuation of the Wynbring channel. (Saline ground waters within the buried sandy palaeochannels are usually electrically conductive and hence the channels can be delineated by EM surveys). The dashed lines show the interpreted outline of the continuation of the channel and its tributaries.


Wynbring PNC Drill Hole Cross SectionWynbring PNC Drill Hole Cross Section

PNC drill section across part of the palaeochannel in the southern portion of Tasman’s EL 3306. Anomalous radiometric responses were recorded within the channel at the weathering interface. Drilling also intersected granitic basement, a favourable source rock for uranium.

The map shows the known rank and volatile matter of the coal in the coal field –which is frequently a good indicator of the gas content of coal

South Wales has some of the gassiest coal in the UK, with a long history of mine explosions.

230 sq km area of PEDL 100, showing the infrastructure and potential local markets which is located directly above the South Wales Coal field.

The UK is now a net importer of petroleum and gas prices are significantly higher (approximately five times Australian prices).

Infrastructure costs, such as pipelines, are much lower than that needed in Australia, making the South Wales project highly attractive.
