Lithostratigraphic setting and structural controls of uranium mineralization in the Main, Central and East zone deposits, ARC Kiggavik Property, Thelon Basin region, Nunavut

Kiggavik矿床和勘探营地位于努纳武特贝克湖以西约80公里处，是加拿大盾这一偏远地区的首批重大铀矿发现之一。自发现铀矿以来，主要运营商Areva Resources Canada(ARC)Inc.已在Kiggavik地区发现了许多其他有前景的铀矿床和前景，目前的储量估计为约51,000吨(1.33亿磅U3O8)，平均铀品位为0.46%。虽然这些矿床的总体背景已经知道了一段时间，但涉及铀矿成因的更具体的地质因素仍然不确定。这项研究旨在更好地了解铀形成的控制和机制，特别是确定各种岩石结构(如断层、断裂)是否以及如何控制成矿过程。这将由硕士和学士级别的学生研究项目分别完成，该项目将使用次地表(钻芯)和地面制图相结合的方式调查主要矿藏附近的岩石类型和结构。然后，这两项研究的结果将与区域尺度的观察相结合和综合，以确定更大尺度上赋矿构造的机制和时间。这项研究的一个重要的相关目标是开发一套地质分析方法，可用于检测/预测经济铀浓度的发生。这些方法的技能和专门知识将在大学和行业人员之间开发和分享，并将直接帮助未来的短期和长期探索。这将有助于在邻近地区划定新的资源，由于该地区如此偏远，需要这些资源来加强其经济活力。这将提高这些资源在未来得到可持续开发的可能性，这将通过提供高薪就业机会和经济稳定，极大地造福于当地的贝克湖村。

The Kiggavik deposit and exploration camp is located ~80 km west of Baker Lake, Nunavut and represents one of the first significant uranium discoveries in this remote part of the Canadian Shield. Since its discovery, work undertaken by the principal operator, AREVA Resources Canada (ARC) Inc., has identified numerous other promising uranium deposits and prospects in the Kiggavik region, with current reserves estimated as ~51,000 tonnes (133 million lbs U3O8) at an average grade of 0.46% uranium. While the general setting of these deposits has been known for some time, the more specific geological factors involved in uranium ore genesis remain uncertain. This research aims to better understand the controls and mechanisms of uranium formation, and in particular, to determine if and how various rock structures (e.g., faults, fractures) controlled the ore-forming process. This will be accomplished by student research projects at the Masters and Bachelors levels, respectively, that will investigate rocks types and structures proximal to the main deposits using a combination of sub-surface (drill-core) and surface mapping. Results from the two studies will then be integrated and synthesized with regional-scale observations to establish both the mechanisms and timing of ore-hosting structures at the larger scale. An important, related objective of this research is to develop a set of methodologies in geological analysis that can be used to detect/predict occurrences of economic concentrations of uranium. Skills and know-how in these methodologies will be developed and shared between university and industry personnel and will directly assist in future short- and long-term exploration. This will help to delineate new resources in the immediate area, which, because it is so remote, are needed to strengthen its economic viability. This will improve the likelihood that these resources will be sustainably developed in the future, which will greatly benefit the local hamlet of Baker Lake by providing high-paying jobs and economic stability.
