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.

Seabee矿，由克劳德资源有限公司拥有和经营，位于SK州拉龙格东北125公里处。自1991年开始开采以来，该存款已生产近100万盎司黄金，平均品位为7.5克/吨，成为萨斯喀彻温省最大的金矿。大部分黄金位于石英脉内，沿着一个主要的断层带，该断层带穿过一个大型镁铁质侵入岩体。然而，过去20年在Seabee地区的勘探也发现了与主要存款不同的其他石英脉型金矿。这项研究的目的是更好地了解这些新的前景中金形成的控制和机制，特别是更好地确定各种岩石结构（例如，断层、断裂）控制了成矿过程。为了实现这一目标，将分别作为学生研究项目，对Seabee矿以西和以北的Santoy湖、Pine湖和Porky湖地区有前途的新矿床进行详细的地质研究。这些研究将涉及地面和地下地质测绘以及对选定的岩心进行观察。然后将这两项研究的结果与区域尺度的观测和选定岩石单位的年龄测定相结合，以确定更大（构造）尺度上的容矿构造的机制和时间。本研究的一个重要的相关目标是开发一套地质分析方法，可用于在该地区未来的勘探中找到经济的金矿集中区。这些方法中的技能和专门知识将在大学和行业人员之间开发和分享，以帮助未来的勘探，目标是刺激新资源的开发并延长采矿营地和生产设施的寿命。
