Bronzewing gold deposit.

The deposit, in Western Australia, is a recent discovery in an area of thick transported overburden and deep weathering. The main rock types are komatiite flows and intrusions, high-Mg and tholeiitic basalt and dolerite, intermediate to felsic volcanic rocks, internal granitoid plutons and medium- to fine-grained clastic and chemical sedimentary rocks. Most rock types are metamorphosed. The principal structural feature is a ductile shear zone with intra-shear zone boudins of pillow lava and ultramafic rock. Below 400 m, mineralisation forms linear, parallel zones whereas in the upper 300 m there is a much more complex geometry controlled by multiple fault and shear zone orientations. Several styles of quartz veining are present. Mineralisation formed in a single major event post-dating the emplacement of the major rock types. Total measured, indicated and inferred resources at December 1996 were 38 300 000 t grading 2.9 g/t Au.
