Giant copper: a new copper-gold exploration target for copper and gold in the Canadian Cordillera

不列颠哥伦比亚省的铜产量占加拿大总产量的一半，其中大部分来自斑岩铜矿。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，最常见于北美和南美的科迪勒拉山脉。这些矿床通常被认为是一个更大的成矿系统的一部分，通常在其正上方有一个浅成低温热液存款。浅成低温热液沉积物常被剥蚀，直接暴露出地表的斑岩型铜存款。在某些情况下，另一种类型的铜存款，一个旅游角砾岩存款，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，斑岩铜矿化发生在系统的深部。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，它们可能提供有用且更明显的勘探目标，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省的巨铜矿具有旅游角砾岩存款的所有特征，具有极好的暴露性和可接近性。迄今为止，在科迪勒拉山脉北方发现了经济型含铜电气石矿床。本提案的目的是支持博士生W. Fischer，对Giant Copper矿区与智利系统的矿物学、化学、构造和一般地质进行详细比较，以评估BC相对丰富的Tourism-braccia角砾岩脉作为BC新勘探目标的潜力及其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Giant Copperexploration物业中铜和金富集的性质，从而为Imperial Metals Corporation目前持有的物业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。费舍尔的论文和任何相关出版物。

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.
