This research will be a first collaborative effort between the Queen's Facility for Isotope Research (QFIR) and Prosperity Goldfields to evaluate the origin and evolution of the Kiyuk Lake gold deposit. This is an unusual gold deposit because it is hosted in a sedimentary basin and is in an underexplored area of Nunavut. Currently much of Canada's gold is produced from the oldest parts of the Canadian Shield. If economic amounts of gold could be found in younger basins such as at Kiyuk Lake, a new timing for gold deposition will have been identified in the Shield and a potential new host for gold will be revealed. Problems to be addressed include the types of alteration minerals and their order of formation relative the gold, the age and chemistry of the alteration assemblages associated with the gold, the origin and character of the fluids that produced the gold relative to barren areas, and how these can be used to detect gold mineralization in the area. This research will involve an MSc student and a Post-Doctoral Fellow (0.2PDF) and 2 Research Associates (5% of their time as RAs) to produce data and new exploration techniques, the PI who will oversee the research and mentor the HQP, and the staff at Prosperity Goldfields who will provide drill core samples and supplementary data. The data and knowledge generated will be original and focussed on a gold deposit hosted in geology that has seen little assessment for its mineral potential. This knowledge will benefit the industry by providing tools to find additional reserves if they are present, as well as both Canada and Nunavut by increasing awareness of potentially new types and areas of gold mineralization in Nunavut. In addition, it will evaluate the use of geochemistry for effective valuation and exploration in an area with very limited outcrop exposure.

这项研究将是女王同位素研究机构（QFIR）和繁荣金矿之间的第一次合作，以评估Kiyuk湖金矿床的起源和演化。这是一个不寻常的金矿，因为它位于沉积盆地中，位于努纳武特的一个未开发地区。目前，加拿大的大部分黄金都是从加拿大地盾最古老的部分开采出来的。如果能在Kiyuk湖等较年轻的盆地中发现具有经济价值的黄金，就能确定盾区金矿沉积的新时间，并揭示潜在的金矿新宿主。待解决的问题包括蚀变矿物的类型及其相对于黄金的形成顺序，与黄金相关的蚀变组合的年龄和化学性质，相对于贫瘠地区产生黄金的流体的来源和特征，以及如何利用这些来探测该地区的金矿化。这项研究将涉及一名硕士生和一名博士后研究员（0.2PDF）以及两名研究助理（他们5%的时间作为RAs），以提供数据和新的勘探技术，PI将监督研究并指导HQP，繁荣金矿的工作人员将提供钻芯样本和补充数据。所产生的数据和知识将是原创的，并将重点放在地质学中几乎没有对其矿产潜力进行评估的金矿。这些知识将通过提供工具来发现额外的储量（如果存在的话），从而使行业受益，同时通过提高对Nunavut潜在的新类型和金矿化区域的认识，加拿大和Nunavut都将受益。此外，它将评价利用地球化学在一个露头非常有限的地区进行有效估价和勘探的情况。
