The Klondike Gold Rush of the 1890s drew thousands of fortune-seekers to the Yukon Territory to mine gold-bearing gravels. Exploration for the bedrock source of gold and other commodities continues to the present day in the Yukon, with $1.8B spent on mineral exploration and development since 2007. Such activity has led to some important advanced-stage mineral exploration projects that have discovered over 8 million ounces of gold, including the Coffee gold deposit, the Klaza gold-silver deposit, the White Gold deposit, and the Nucleus gold-silver deposit. However, much of the mineral exploration that was done was unable to benefit from an understanding of metallogeny - the geological controls on where ore forms - because it hadn't yet been established. The research project provides a framework for the long and complex history of ore formation in western and southern Yukon. The metallogenic understanding will be achieved through detailed studies on individual mineral deposits, regional studies involving geological mapping and interpretation of fault locations, characterization of igneous rocks potentially associated with gold or copper ore, application of advanced techniques for dating the timing of rock and ore deposit formation, and the description of ores to develop better ore deposit models. Field and analytical studies in Yukon will be integrated with information emerging from eastern and interior Alaska through collaborations with government geologists.Yukon and Canada will benefit initially from the generation of new geoscientific information and the mineral exploration it attracts, and ultimately, through the training, jobs, wealth creation and tax benefits that can arise from the successful application of this knowledge to mineral exploration and development.

19世纪90年代的克朗代克淘金热吸引了数以千计的淘金者来到育空地区开采含金砾石。育空地区至今仍在继续勘探黄金和其他大宗商品的基岩来源，自2007年以来，已在矿产勘探和开发上花费了18亿美元。这类活动导致了一些重要的高级矿产勘探项目，已发现超过800万盎司的黄金，包括咖啡金矿、克拉扎金银矿床、白色金矿和Nucleus金银矿床。然而，已经完成的大部分矿产勘探无法从对成矿学的理解中受益--成矿学是指对矿石形成地点的地质控制--因为它还没有建立起来。该研究项目为育空地区西部和南部漫长而复杂的成矿历史提供了一个框架。将通过对个别矿藏的详细研究、涉及地质测绘和断层位置解释的地区性研究、可能与金或铜矿有关的火成岩的表征、应用先进技术测定岩石和矿床形成的时间以及描述矿石以开发更好的矿床模型来实现对成矿作用的了解。育空地区的实地和分析研究将通过与政府地质学家的合作，与阿拉斯加东部和内陆出现的信息相结合。育空地区和加拿大最初将受益于新的地球科学信息及其吸引的矿产勘探，最终将通过培训、就业、财富创造和税收优惠，成功地将这些知识应用于矿产勘探和开发。
