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.

由Claude Resources Ltd.拥有和运营的Seabee矿场位于SK La Ronge东北125公里。自1991年开采开始以来，这笔押金的平均级别为7.5 g/t，使其成为萨斯喀彻温省最大的生产黄金矿山。大部分黄金位于石英静脉内，沿着主要断层区域，该断层杆穿过大型镁铁质侵入岩体。但是，在过去的二十年中，Seabee地区进行的探索也确定了其他石英静脉持有的黄金前景，它们与主要沉积物不同。这项研究旨在更好地了解这些新前景中黄金形成的控制和机制，尤其是更好地确定各种岩石结构（例如断层，裂缝）如何控制矿化过程。为了实现这一目标，将作为学生研究项目进行，分别对Seabee矿山西部和北部的Santoy Lake和Pine and Porky Lakes地区有希望的新矿床进行详细的地质研究。这些研究将涉及表面和地下地质映射和观察选定的钻核。然后，这两项研究的结果将与区域尺度观测值和所选岩石单元的年龄进行整合和合成，以在较大（构造）尺度上建立矿石托管结构的机制和时机。这项研究的一个重要的，相关的目标是在地质分析中开发一系列方法论，这些方法可用于在未来对该地区的探索中找到经济黄金浓度。这些方法论中的技能和知识将在大学和行业人员之间发展和共享，以帮助将来探索，以刺激新的资源开发并延长该采矿营和生产设施的寿命。
