AN 366 Emu Fault 2006 Annual report

Abstract

The Coxco prospect is located about 10 km 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, fractured controlled characteristics with both sedimentary breccias and massive dolomite tectonic breccias respectively. A highly regular, cavitated, karst weathering profile within which conventional drilling techniques have failed to adequately recover oxide sample material, further complicate a deposit which has confounded multiple compaigns of evaluation spanning over 90 years. During the reporting period, programme review, site visits for boundary rehabilitation were undertaken. No other significant work was undertaken during the year lack of exploration capital arising from the dominance of the Open Pit Expansion project at McArthur River Mine.
