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.

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脉地带，最常见于较年轻的山脉地带，如北美洲和南美洲的科迪勒拉山脉。这些矿床通常被认为是一个更大的矿化系统的一部分，通常在其正上方有一个浅成低温热液存款。通常浅成低温热液存款 ** 已被侵蚀，直接暴露出地表的斑岩铜矿存款。在某些情况下，另一种类型的铜存款，一个电气石角砾岩存款，坐在上面的斑岩。智利Los Bronces -里奥布兰科系统中的旅游角砾岩型铜矿是此类矿床的典型经济类型，斑岩型铜矿化发生在系统的更深处。由于电气石角砾岩矿床位于铜斑岩矿床之上，通常在地表，它们可能提供有用的和更明显的勘探目标，并且是理想的，因为它们不仅包含一个，而是两个潜在的铜矿。位于南 **BC的巨型铜矿显示了旅游角砾岩存款的所有特征，具有极好的暴露和可接近性。迄今为止，在科迪勒拉山脉北方尚未发现有经济价值的含铜矿床。这个提议的目的是支持一个博士生，W。Fischer，对Giant Copper矿区的矿物学、** 化学、构造学和一般地质学与智利系统进行详细比较，以评估不列颠哥伦比亚省相对丰富的电气石角砾岩脉作为不列颠哥伦比亚省新勘探目标 ** 的潜力，以及它们作为更深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巨型铜 ** 勘探财产中铜和金富集的性质，从而为帝国金属公司目前持有的 ** 财产提供更好的勘探模型。这也将使他们处于一个极好的位置，以获得新的财产和扩大其控股。结果最终将通过W.费舍尔的论文和任何相关出版物。
