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”的来源位于附近的基岩中，这种“硬岩”金仍然是矿产勘探的重点。近年来，育空地区金矿勘探投资超过 7.5 亿美元，但其中大部分资金都没有得到充分利用，因为人们对金矿形成位置的地质控制还没有很好的了解。建立与金矿形成相关的地质特征可以降低勘探过程的风险并带来新的发现。咖啡矿床蕴藏着超过 400 万盎司的黄金，但其形成过程尚未确定。该研究项目将确定咖啡及周边地区的控矿特征，包括矿液的化学成分、地质和结构背景、地壳隆起以及矿化时间。这些限制可以导致预测在矿床和区域范围内可以在哪里找到额外的黄金资源。 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控制提供知识库。这些知识的传播将造福于探矿者、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，使他们能够做出更自信、更高效的勘探决策。这个过程中的所有步骤都具有经济效益，从收购财产的初始投资，到勘探活动，再到发现、矿山开发和矿物开采。咖啡金矿的经济预测表明，它将在 12 年内产生 $2.4B 的收入。 加拿大最初将受益于新地球科学信息的产生，但最终将受益于这些知识的应用所带来的培训、就业、财富创造和税收优惠。
