Abstract: The Coxco Prospect, AN 366 North is located approximately 10 kilometres southeast of the HYC deposit. It is a sub-economic carbonate hosted Zn- low Pb deposit within highly prospective Proterozoic McArthur Group stratigraphy directly adjacent to a major regional structure, the north-south trending Emu Fault zone. Mineralisation exhibits both stratabound and structurally complex, fracture controlled characteristics within both sedimentary breccias and massive dolomite tectonic breccias respectively. A highly irregular, cavitated, karstic weathering profile, within which conventional drilling techniques have failed to adequately recover oxide sample material, further complicate a deposit which has confounded multiple campaigns of evaluation spanning over 90 years. Carefully targeted diamond drilling completed during the 2009 dry season has identified untested deeper potential within the Coxco Dolomite for higher grade mineralisation, along the hypothesized shallowly north-plunging intersection of the Coxco Fault and the Emu Fault Zone. Major activities for this year included the drilling of two diamond holes totalling 442.9 metres, structural logging, analysis, report writing and the assaying and interpretation of 275 diamond drill core samples. An estimate has been made for the cost of mine-based heavy equipment and Surveyor's time used in access track refurbishment and drill site preparation.
