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 Prosperity Goldfields 之间的首次合作，旨在评估 Kiyuk 湖金矿的起源和演化。这是一个不寻常的金矿床，因为它位于沉积盆地中，并且位于努纳武特地区尚未开发的地区。目前，加拿大的大部分黄金产自加拿大地盾最古老的部分。如果在基尤克湖等较年轻的盆地中发现了经济数量的黄金，那么地盾中将确定金沉积的新时机，并且将揭示潜在的新金矿。要解决的问题包括蚀变矿物的类型及其相对于金的形成顺序、与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金的流体的来源和特征，以及如何利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、一名博士后研究员 (0.2PDF) 和 2 名研究助理（5% 的时间担任 RA），以提供数据和新的勘探技术，PI 负责监督研究并指导 HQP，Prosperity Goldfields 的工作人员将提供钻芯样本和补充数据。生成的数据和知识将是原创的，并集中于地质学中的金矿床，该矿床对其矿产潜力几乎没有进行评估。这些知识将通过提供工具来寻找额外的储量（如果存在），从而使该行业受益，并通过提高对努纳武特地区潜在的新金矿化类型和地区的认识，使加拿大和努纳武特地区受益。此外，还将评估地球化学在露头暴露非常有限的地区进行有效评估和勘探的用途。
