Asbestos Creek prospect
Takaka Valley and Cobb River: Lenses, veins and disseminations of gold-bearing pyrrhotite-pyrite-chalcopyrite pentlandite mineralisation are associated with metadiorite dikes in Devil River Volcanics of the Meter Creek area, adjacent to the Cobb Igneous Complex (Henderson et al., 1959; White and Whittle, 1961; Grindley, 1962; Johnston, 1969; Smale, 1971; Hunter, 1977; Stegman, 1988). The mineralised lenses are segregations up to 3 m long and 0.9 m thick which have yielded assays of up to 4.5% Ni and 1.3% Cu in exploration work by Kennecott. Pyrrhotite is the major sulphide (>60%), with >10% associated pentlandite and minor chalcopyrite (<1%). (Christie & Brathwaite, 1995)
