Gold is synonymous with the Yukon Territory, but much of the gold has been won from surface gravels. The source of this "placer" gold is in the nearby bedrock, and this "hardrock" gold continues to be the focus of mineral exploration. In recent years, more than $750M has been invested in Yukon gold exploration, but much of this money was poorly spent because the geological controls on where the gold forms were not well understood. Establishing the geological features relevant to gold formation can reduce the risk of the exploration process and result in new discoveries. The Coffee deposit hosts more than four million ounces of gold, but the processes leading to its formation are not established. This research project will identify ore-controlling features at Coffee and the surrounding region, including the chemistry of the ore fluids, the geologic and structural setting, uplift of the crust, and timing of mineralization. These constraints can lead to predictions about where additional gold resources can be found, both at the deposit and regional scale.****The project will provide a knowledge base for understanding controls on gold in Yukon and other parts of the Cordillera. The knowledge will be communicated for the benefit of prospectors, government geological surveys, policy makers, and academics. This research will provide exploration companies with practical concepts on which to base more confident and efficient exploration decisions. All steps in this process have economic benefits, from initial investments to acquire the property, to exploration activities, and hopefully to discovery, mine development, and mineral extraction. Economic projections of the Coffee gold deposit indicate that it will generate $2.4B in revenues over a 12-year period. ****Canada will benefit initially from the generation of new geoscientific information, but ultimately through the training, jobs, wealth creation and tax benefits that can arise from the application of this knowledge.******

黄金是育空地区的代名词，但大部分黄金都是从地表砾石中开采出来的。这种“砂金”的来源是在附近的基岩中，这种“硬岩”金仍然是矿产勘探的重点。近年来，育空地区的黄金勘探投资超过7.5亿美元，但由于对黄金形成的地质控制没有很好地了解，这些钱中的大部分都花得很少。确定与金形成有关的地质特征可以降低勘探过程的风险，并导致新的发现。咖啡存款拥有超过400万盎司的黄金，但导致其形成的过程并不确定。该研究项目将确定咖啡及周边地区的控矿特征，包括矿石流体的化学性质、地质和结构背景、地壳隆起和矿化时间。这些限制因素可以预测在存款和区域范围内可以找到更多的黄金资源。****该项目将为了解育空地区和科迪勒拉山脉其他地区的黄金管制提供一个知识基础。这些知识的传播将有利于探矿者、政府地质调查、政策制定者和学者。这项研究将为勘探公司提供实用的概念，以更自信和有效的勘探决策为基础。这个过程中的所有步骤都有经济效益，从最初的投资到获得财产，到勘探活动，最后是发现，矿山开发和矿物开采。对咖啡黄金存款的经济预测表明，它将在12年内产生24亿美元的收入。* 加拿大最初将受益于新的地球科学信息的产生，但最终将受益于应用这一知识可能带来的培训、就业、财富创造和税收优惠。
