Tourmaline Breccias And A Porphyry-Style Cu-Au System At Bulagidun Prospect

The Bulagidun copper-gold system occurs in Tertiary andesitic volcanic rocks. It is located (figure 1, from Curless, 1991) ca. two days walk from the coast in an isolated area on the northerly slope of the main range of mountains, in steep terrain dissected by erosion. Detailed and district-scale exploration from 1988 to 1991 by BHP Minerals defined a small, sub-economic resource of gold and copper. One preliminary estimate of the resource in bedrock suggests 14.4 million tons at 0.68 grams / Tonne Au and 0.61% Cu, in multiple small bodies.
