British Columbia accounts for half of Canada's copper production and the bulk of that copper derives fromporphyry 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 youngerbelts such as the cordilleras of North and South America. These deposits are generally thought to be part of alarger mineralizing system often with an epithermal deposit sitting directly above. Often the epithermal deposithas been eroded away, directly exposing the porphyry copper deposit at surface. In some cases, another type ofcopper deposit, a tourmaline breccia deposit, sits above the porphyry. Tourmaline breccia copper deposits inthe Los Bronces - Rio Blanco systems in Chile are typical economic versions of these deposits with porphyrycopper mineralization occurring deeper in the system. As the tourmaline breccia deposits sit above the copperporphyry deposits, often at surface, they may provide a useful and more-distinct exploration target and aredesirable as they contain not just one, but two potential copper mines. The Giant Copper property in SouthernBC exhibits all the characteristics of a tourmaline breccia deposit, has excellent exposure, and acccess. To dateno economic copper-bearing tourmaline deposits have been found in the northern Cordillera. The aim of thisproposal 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 thepotential of tourmaline breccia veins, which are relatively abundant in BC, as a new exploration target for BCand their value as an exploration vector to deeper porphyry copper deposits. The major outcomes of this projectare to develop a better understanding of the nature of copper and gold enrichment in the Giant Copperexploration property, resulting in better exploration models for Imperial Metals Corporation's currently heldproperties. 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.

不列颠哥伦比亚省占加拿大铜产量的一半，其中大部分铜来自斑岩铜矿。这些矿床通常含有相当数量的其他金属，如金、银和钼。它们出现在世界各地的山区，最常见的是年轻的地带，如北美和南美的科迪拉拉山脉。这些矿床通常被认为是更大的成矿系统的一部分，通常在其正上方有一个浅成热液矿床。浅成热液沉积常被剥蚀，直接露出地表斑岩铜矿。在某些情况下，另一种类型的铜矿--电气石角砾岩矿床--位于斑岩之上。智利Los Bronces-Rio Blanco系统中的电气石角砾岩铜矿床是这些矿床的典型经济版本，斑岩铜矿化发生在该系统的更深处。由于电气石角砾岩矿床位于铜斑岩矿床之上，通常位于地表，因此它们可能提供一个有用的、更独特的勘探目标，并且由于它们不仅包含一个，而是两个潜在的铜矿，因此是可取的。位于英国南部不列颠哥伦比亚省的巨型铜矿显示出电气石角砾岩矿床的所有特征，具有极好的曝光性和接近性。到目前为止，在科迪勒拉北部已发现了含铜电气石矿床。这项建议的目的是支持博士生W.Fischer对巨型铜矿的矿物学、化学、构造和一般地质与智利系统进行详细的比较，以评估电气石角砾岩脉作为BC新的勘探目标的潜力以及它们作为更深部斑岩铜矿勘探载体的价值。该项目的主要成果是更好地了解Giant Copper勘探矿产中铜和金的富集性，从而为Imperial Metals Corporation目前拥有的矿产建立更好的勘探模式。这也将使他们处于一个很好的位置，可以获得新的财产并扩大他们的持有量。结果最终将通过W.Fischer的论文和任何由此产生的出版物公开公布。
