Syntectonic Base-Metal Mineralisation with an Epithermal Gold Overprint: McKinnons Gold Deposit, Cobar, NSW, Australia

摘要

The McKinnons gold deposit is hosted by weakly deformed, Palaeozoic metasedimentary rocks of the Cobar Basin in the western Lachlan Fold Belt of New South Wales. Mineralisation comprised a largely supergene resource of 1.7 Mt of ore, grading 1.7 g/t gold, established over structurally controlled, primary gold and base-metal mineralisation in underlying. carbonate-rich meta-siltstones and sandstones of Early Devonian age.
