Narnoo Gold
Narnoo is owned 100% by A1 and is located approximately 250 kilometres east of Kalgoorlie and 30 kilometres southeast of the Minigwal and Lightfoot playa lake systems. The tenements overlap the southern limits of the Archaean Jasper Hills Greenstone Belt and sedimentary rocks of the Officer Basin, which is partly underlain by the Proterozoic Albany-Frazer Tectonic Province.
The Project has strong potential for gold and uranium deposits.
An extensive soil sampling program carried out by A1 during the last quarter of 2005, covering an area of 100 square kilometres, searching for gold, nickel, copper and uranium lead to the discovery of a large gold soil anomaly (“Desert Sun Anomaly”). Desert Sun sits in a geological setting that is an optimal trap site for gold mineralization.
The anomaly has a peak value of 23ppb gold and is approximately 2,000 x 700 metres based on 6ppb Au. The regolith is made of sandy soil, indicating that the anomaly is particularly significant.
Previous owners of the Narnoo Project conducted RC and aircore drilling on locations near Desert Sun yielding results at Chillon: 1m @ 1.40g/t Au, Rusty: 1m @ 3.74g/t Au and Wallbanger: 1m @ 3.49g/t Au. Follow-up with limited RC exploration drilling did not include the area of the Desert Sun anomaly.
Aircore drilling over the Lightfoot gold prospect in 1996/97 located a saprolite anomaly more than 1 kilometre long in a north-south direction which averaged 0.5g/t gold with a peak value of 1m @ 2.48g/t gold. Subsequent deeper RC drilling during 1998, failed to locate the primary source of the gold.
Soil sampling over new areas of the Project are planned to continue through 2006.
Narnoo Uranium and Multi Element Potential
An independent review by geophysical consultants, of preliminary imagery from a recent government radiometric survey, shows anomalistic uranium channel radioactivity at Narnoo.
The East Yilgarn preliminary potassium–thorium–uranium image recently released by the Geological Survey of Western Australia was reviewed by Southern Geoscience Consultants. The review was of a preliminary Ternary Radiometric image made from the raw, unlevelled data.
The data indicates uranium channel anomalism along the edges of playa lake drainages, situated near the privately held Mulga Rock Uranium Deposit.
A1 geologists will incorporate investigation of the indicated uranium occurrences in their current exploration programs by undertaking scintillometer surveys and downhole gamma probes to locate, confirm and quantify the radiometric anomalies.
The indication of uranium anomalism at surface is significant as it is near the Mulga Rock Uranium Deposit. Originally delineated by the Japanese Government’s Power Reactor and Nuclear Fuel Development Corporation during the 1980s, Mulga Rock has a published resource of 10.8Mt @ 0.12% uranium (Mulga Rock Uranium and Multi-element Deposits, Officer Basin, WA G B Douglas, C R M Butt and D J Gray, CSIRO Land and Water, CRC LEME 2003).
A1 Minerals believes the Narnoo project has the potential to host sandstone “roll-front”, lignite and surficial calcrete style uranium deposits. These tenements also abut Uranio's/Deep Yellow Ponton Uranium Prospects.
Gold, Base Metals and Diamonds
There are several high priority structural targets in the Narnoo region, where early phase gold exploration is highly recommended. The area is grossly under-explored for massive sulphide nickel deposits and a possible kimberlitic diamond exploration target is recognised. Concepts for the discovery of VMS copper mineralisation and a very large source of groundwater are also identified.
