Canada is well endowed with natural resources, and economic development in northern Canada, in particular, is driven by the search for, and sustainable exploitation of these resources. As an example, most of the large gold deposits in Quebec, Ontario, and the NWT, are associated with faults and quartz veins that cut rocks of the Canadian Shield that are Archean in age (older than 2.5 billion years old). These are called "orogenic gold deposits" as they formed during ancient, mountain building events, and recently some significant examples of this type of deposit have been discovered in younger, Paleoproterozoic (2.5 to 1.6 billion years old) rocks in Nunavut. SSR Mining, the company with which this proposal has been developed, operates the Seabee Gold Operation, which is within similar age rocks in northern Saskatchewan. The company has been operating the Seabee gold deposit, which recently closed, and the adjacent Santoy deposit, and are actively exploring the adjacent area in the search for new, and hopefully, economic gold mineralization. In detail, the project will form part of a M.Sc. thesis at the University of Saskatchewan, and will focus on the analysis of representative samples of the various rock types from the exploration property. Thin sections of the rocks will be used to determine the minerals, textures, and the composition of the minerals, using petrographic microscopy, and electron microprobe analysis; the latter technique is not routinely available to minerals companies. A portion of the rocks will also be analyzed for their overall chemical composition, which will provide constraints on the origin, and tectonic setting at the time the rocks formed. In the end, the company will have a better understanding of the origin of the rocks in the region, and be able to focus their exploration on the rock types with the best chance of hosting new deposits. The discovery of a new deposit would spark economic activity in this isolated part of the Canadian Shield in northern Saskatchewan.

加拿大拥有丰富的自然资源，特别是加拿大北方的经济发展是由寻找和可持续开发这些资源所推动的。例如，魁北克、安大略和西北地区的大多数大型金矿都与断层和石英脉有关，这些断层和石英脉切割了太古代（超过25亿年）的加拿大地盾岩石。这些被称为“造山金矿床”，因为它们是在古代造山运动中形成的，最近在努纳武特的古元古代（25亿至16亿年）岩石中发现了这种类型存款的一些重要例子。SSR矿业公司是与该公司一起制定这一建议的，该公司经营着Seabee黄金业务，该业务位于萨斯喀彻温省北方的类似年龄岩石内。该公司一直在经营最近关闭的Seabee金矿存款和邻近的Santoy存款，并正在积极探索邻近地区，以寻找新的，希望是经济的金矿化。具体而言，该项目将成为萨斯喀彻温大学硕士论文的一部分，并将侧重于分析勘探性质的各种岩石类型的代表性样品。岩石的薄片将用于确定矿物，纹理和矿物的成分，使用岩相显微镜和电子探针分析;后一种技术通常不适用于矿产公司。还将分析一部分岩石的整体化学成分，这将提供对岩石形成时的起源和构造环境的限制。最终，该公司将更好地了解该地区岩石的起源，并能够将勘探重点放在最有可能容纳新矿床的岩石类型上。一个新的存款的发现将引发经济活动在这个孤立的部分加拿大地盾在北方萨斯喀彻温省。
