Abstract

Previous investigations include basemetal exploration by Geopeko and gold exploration by W.R. Grace and Western Mining Corporation. Open file reports of this activity are available at the Department of Mines and Energy, Darwin. Exploration during the first year of title was directed at gold and included detailed geological mapping and reconnaissance rock chip sampling. Gold distribution throughout the tenement was assessed using bulk (5kg minus 10 mesh) and conventional (1kg minus 30 mesh) stream sediment samples. Analytical methods for gold determination were cyanide leach and conventional graphite furnace AAS respectively. The tenement also falls within a regional airmagnetic and radiometric survey completed for Golden Plateau NL. Conclusions & Recommendations - Surface sampling to date has returned uniformly low gold values in both drainage samples and rock chips. Geological mapping indicates horizons prospective for stratiform gold mineralisation in the Koolpin Formation. Aerial magnetic features appear to be caused by litbological variations rather than mineralisation. It is recommended that study of airmagnetic data is completed and prospective horizons within the Koolpin Formation should be thoroughly rock chip sampled.
