Seabee Mine, owned and operated by Claude Resources Ltd., is located 125 km northeast of La Ronge, SK. Since mining began in 1991, this deposit has produced nearly one million ounces of gold at an average grade of 7.5 g/t., making it the largest producing gold mine in Saskatchewan. Most of the gold is located within quartz veins along a major fault zone that cuts through a large mafic intrusive rock body. However, exploration in the Seabee area in the past two decades has also identified other quartz vein-hosted gold prospects that are different from the main deposit. This research aims to better understand the controls and mechanisms of gold formation in these new prospects, and in particular to better determine how various rock structures (e.g., faults, fractures) controlled the mineralization process. In order to accomplish this, detailed geological studies of promising new deposits in the Santoy Lake and Pine and Porky lakes areas, west and north of Seabee mine, respectively, will be undertaken as student research projects. These studies will involve surface and underground geological mapping and observation of selected drill-core. Results from the two studies will then be integrated and synthesized with regional-scale observations, and age-dating of selected rock units, to establish both the mechanisms and timing of ore-hosting structures at the larger (tectonic) scale. An important, related objective of this research is to develop a set of methodologies in geological analysis that can be used to find economic gold concentrations in future exploration of this region. Skills and know-how in these methodologies will be developed and shared between university and industry personnel to help in future exploration, with the goals of stimulating new resource development and extending the life of this mining camp and production facility.

克劳德资源有限公司拥有并经营的Seabee金矿位于SK La Ronge东北125公里处，自1991年开始开采以来，该矿床已生产了近100万盎司的黄金，平均品位为7.5克/吨。使其成为萨斯喀彻温省最大的金矿。大部分黄金位于沿主要断裂带的石英脉中，该断裂带穿过大型基性侵入岩体。然而，在过去的二十年中，在Seabee地区的勘探也发现了与主矿床不同的其他石英脉型金矿远景。本研究旨在更好地了解这些新远景区金矿形成的控制因素和机制，特别是更好地确定各种岩石构造（如断层、裂隙）如何控制成矿过程。为了完成这项工作，将分别作为学生研究项目对Seabee矿西部和北部的Santoy湖和Pine和Porky湖地区有希望的新矿床进行详细的地质研究。这些研究将涉及地表和地下地质测绘以及对选定岩心的观察。然后，这两项研究的结果将与区域尺度的观测和选定岩石单元的年龄定年相结合和综合，以在更大的（构造）尺度上确定含矿结构的机制和时间。这项研究的一个重要的相关目标是发展一套地质分析方法，以便在该地区今后的勘探中发现具有经济效益的金矿。这些方法的技能和专门知识将在大学和工业人员之间发展和分享，以帮助今后的勘探，其目标是促进新资源的开发和延长这个采矿营地和生产设施的寿命。
