British Columbia accounts for half of Canada's copper production and the bulk of that copper derives from porphyry copper deposits. These deposits generally contain appreciable amounts of other metals such as gold, silver, and molybdenum. They occur in mountain belts around the world and are most common in younger belts such as the cordilleras of North and South America. These deposits are generally thought to be part of a larger mineralizing system often with an epithermal deposit sitting directly above. Often the epithermal deposit has been eroded away, directly exposing the porphyry copper deposit at surface. In some cases, another type of copper deposit, a tourmaline breccia deposit, sits above the porphyry. Tourmaline breccia copper deposits in the Los Bronces - Rio Blanco systems in Chile are typical economic versions of these deposits with porphyry copper mineralization occurring deeper in the system. As the tourmaline breccia deposits sit above the copper porphyry deposits, often at surface, they may provide a useful and more-distinct exploration target and are desirable as they contain not just one, but two potential copper mines. The Giant Copper property in Southern BC exhibits all the characteristics of a tourmaline breccia deposit, has excellent exposure, and acccess. To date no economic copper-bearing tourmaline deposits have been found in the northern Cordillera. The aim of this proposal is to support a PhD student, W. Fischer, to undertake a detailed comparison of the mineralogy, chemistry, tectonics, and general geology of the Giant Copper property with the Chilean system to assess the potential of tourmaline breccia veins, which are relatively abundant in BC, as a new exploration target for BC and their value as an exploration vector to deeper porphyry copper deposits. The major outcomes of this project are to develop a better understanding of the nature of copper and gold enrichment in the Giant Copper exploration property, resulting in better exploration models for Imperial Metals Corporation's currently held properties. It will also place them in an excellent position to acquire new properties and extend their holdings. Results will ultimately be publicly available via W. Fischer's thesis and any resulting publications.
