Partial surrender report for EL 9890 'Yambla', 20th May 2004

Abstract

Exploration Licence 9890 is located at Yambla in the northeast Arunta Province of the Northern Territory. Exploration targets include multi-element PGE, Cu, Au, Ag and U mineralisation in the Central Australian Proterozoic Basement Complex. Uranium as well as Cu, Ag, Pb, Zn mineralisation was found by PNC Exploration (Australia) Pty Ltd in the early 1990's in altered Amphibolite host rocks. In the early 1990's exploration by PNC Exploration (Australia) Pty Ltd located a 1400 m long radiometric anomaly (Yambla Prospect) within the Yambla Amphibolite, a typical hornblende-feldspar rock, which is part of the regional Riddock Amphibolite. It is 10-50 m thick, and in the prospect area dips about 15degrees west. Additional to the Yambla Prospect, Cu, Ag, Pb and, Zn occurrences were also identified on the tenement. The Culay Cu-Au prospect is located nearby within RO 1369, an area reserved from occupation under the Mining Act in May 1997 covering the old Valiant Sisters Mica Mining Area. Regional prospecting and geological mapping showed that the upper Riddock Amphibolite contact is generally gradational into biotite rich felsic gneiss; there is often a narrow sillimanite rich unit above this gradational contact. The sequence grades further upwards into more felsic and garnetiferous biotite gneiss with sporadic and discontinuous lenses of marble and hessianite bearing calc-silicate gneiss.
