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设施（QFIR）和繁荣金矿之间的第一次合作，以评估基约克湖金矿存款的起源和演变。这是一个不寻常的金矿存款，因为它是在沉积盆地和在努纳武特勘探不足的地区。目前，加拿大的大部分黄金都产自加拿大地盾最古老的部分。如果能在基尤克湖等较年轻的盆地中发现经济数量的黄金，那么将在地盾中确定黄金沉积的新时间，并将揭示潜在的新黄金宿主。要解决的问题包括蚀变矿物的类型和相对于金的形成顺序，与金相关的蚀变组合的年龄和化学，相对于贫瘠地区产生金的流体的起源和特征，以及如何使用这些来检测该地区的金矿化。这项研究将涉及一名硕士生和一名博士后研究员（0.2PDF）和两名研究助理（5%的时间作为RA），以产生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岩心样本和补充数据。产生的数据和知识将是原始的，并集中在地质学中的黄金存款，很少对其矿产潜力进行评估。这一知识将有利于该行业，提供工具，以找到更多的储备，如果他们是存在的，以及加拿大和努纳武特，提高认识的潜在新类型和地区的金矿化在努纳武特。此外，它还将评价利用地球化学在露头非常有限的地区进行有效评价和勘探的情况。
