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。它们发生在世界各地的山区，最常见的是在年轻地带，如北美和南美的科迪勒拉山脉。这些矿床通常被认为是更大的矿化系统的一部分，通常在其正上方有浅成热液矿床。浅成热液矿床往往被侵蚀掉，直接暴露出地表的斑岩铜矿床。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—里约热内卢Blanco体系中的电气石角砾岩铜矿床是此类矿床的典型经济型，斑岩铜矿成矿发生在体系深部。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，而且包含两个潜在的铜矿，因此它们是可取的。南nbc巨型铜矿物性具有电气石角砾岩矿床的全部特征，具有良好的出露性和可得性。迄今为止，在科迪勒拉北部未发现有经济价值的含铜电气石矿床。该提案的目的是支持博士生W. Fischer与智利系统进行Giant Copper属性的矿物学，化学，构造和一般地质的详细比较，以评估电气石角砾岩脉（在BC省相对丰富）作为BC省新的勘探目标的潜力及其作为更深斑岩铜矿的勘探向量的价值。该项目的主要成果是更好地了解Giant Copperexploration地产中铜和金富集的性质，从而为帝国金属公司目前持有的地产提供更好的勘探模式。这也将使他们在收购新房产和扩大持股方面处于有利地位。结果最终将通过W. Fischer的论文和任何相关出版物公开。

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.
