Unconformity-related uranium deposits constitute ~33% of the western world's uranium resources. The largest, high-grade unconformity-related uranium deposits in the world occur in the Athabasca Basin, Saskatchewan, Canada, and include the McArthur...

Airborne magnetic/radiometric surveys and follow-up gravity surveys carried out in a search for possible Olympic Dam type orebodies have indicated depths to magnetic basement in excess of 1000 m in the Lake Hart area of the Stuart Shelf. The...

Grid-based gravity, ground magnetic and EM depth sounding surveys were conducted in the Coondambo area in the search for Olympic Dam style mineralisation possibly associated with regional gravity highs. The licensee failed to attract a joint venturer...

Continuing exploration in the Woomera area has included the acquisition of a ground magnetic and gravity survey over the Buller Dam anomaly, which lies on the western flank of the Acropolis aeromagnetic anomaly, and this work confirmed that the former...

Exploration undertaken on ground situated east of Pernatty Lagoon has included the acquisition of extensive ground magnetic and gravity surveys plus a small aerial magnetic and radiometric survey, and performing many specific gravity and magnetic...

Exploration for Olympic Dam-style Cu-Au-U mineralisation, undertaken over areas to the south-east of Arcoona Homestead and in the vicinity of Woomera township, has comprised numerous reconnaissance and then detailed gravity, ground magnetic and CSAMT...

Ongoing copper exploration in the Mount Gunson area was directed primarily at locating economic stratiform mineralisation in the Tapley Hill Formation, which overlies Pandurra Formation and the associated Cattlegrid orebody. New work comprised...

Ongoing exploration for Olympic Dam-style Cu-Au-U mineralisation, over an area centred ~15 km south-east of Arcoona Homestead, during this period comprised 3D geophysical modelling of possible source geometries for, and RC drilling (10 holes, total...

WMC's Stuart Shelf exploration activities from 1975 to 1985 have sought mainly Olympic Dam style mineralisation (copper - uranium - precious metals in haematitic breccia host rocks), with lesser emphasis directed at: possible distal analogues of the...

Exploration for Olympic Dam-style mineralisation, undertaken over an area centred ~15 km south-east of Arcoona Homestead on the Stuart Shelf, which includes WMC's formerly partly tested Emmie Bluff prospect, has comprised the acquisition of ground...

Exploration of an area situated between Whyalla, Iron Knob and The Bluff overlooking Myall Creek, 20 km south-west of Port Augusta, aimed to test for Olympic Dam - type Cu-U-Au mineralisation associated with products of igneous activity located in and...

The three licences now being surrendered were originally taken out by Seltrust in the mid-1970s to search for stratabound base metals and Olympic Dam type mineralisation. After Seltrust withdrew from the subsequently formed Stuart Shelf joint venture...

Following a review of existing regional geophysical and geological data for the north-western Stuart Shelf, grid-based gravity and ground magnetic surveys were run to further outline two broad gravity highs associated with discrete magnetic anomalies,...

At the request of Mr. C. England, Assistant Engineer for Design, E. and W.S. Department, the sites for 5 alternative water storage facilities near Whyalla were examined on 17th and 18th February, 1965. On 18th February, the inspections were in company...

A proposed increase in tonnage treated by the Mill at Mt. Gunson Copper Mine will require an increase in withdrawal from the well field from the present level of approximately 4 000 gph, (18.'2 m5 p.h.) to 9 000 gph (41.0 m p.h.). Careful management...

13 of 38 wells were completed as production wells. Pump testing showed that 6 were capable of yielding 50 kl/day or more for 2 year period. Salinity was in excess of 10 000 mg/L TDS except near Glendambo where water from 4000 to 8000 mg/L was...

Of 16 wells drilled, only 6 have an adequate supply of saline groundwater for construction use. On the western part of the section, 4 wells into the deeper fractured rock aquifer were dry. Subsequently another 8 randomly sited wells were drilled into...
