Pilbara Projects

Pilbara Project

Westar’s Opaline Well Project lies within the historical Nullagine Goldfield some 40 km to the west of the township of Nullagine and in similar geology to the 1.25 million ounce Warrawona deposit ~70km to the NE of Opaline Well.

Historical mining centres in proximity to the project area include Edelweiss and Corboys (where gold mineralisation is interpreted to be confined to quartz veins hosted in basalts), the Ore Tree Hill gossan trend, which represents a superficial development of copper mineralisation on altered, weakly mineralised pillowed and high-magnesian basalts and Victory-Tabletop, where significant and extensive carbonate alteration and quartz veining is associated with gold mineralisation. The Victory Mine had limited production with 1,818.4 t of ore processed at an average grade of 31.6 g/t gold for 57.4 kg (1,845 oz) of gold mined. Other mining activity at Coongan Star and Consolidated Gold Mines produced 2,655 t of ore at an average grade of 58.5 g/t gold for 155.3 kg (4,993 oz) of gold (Gondwana Resources, 2006).
