Most of the large historical gold deposits in Canada are associated with rocks of the Canadian Shield that are older than 2.5 billion years old. These are called "orogenic gold deposits" as they formed during ancient, mountain building events. Similar gold deposits are found in the Canadian Shield of central and arctic Canada, but are associated with a younger (about 1.8 billion years old) mountain belt, called the Trans-Hudson Orogen. However, the origin of these deposits are not well understood, and so this large region may be underexplored. SSR Mining Inc., the company with which this proposal has been developed, operates the only gold mine in Saskatchewan, and is located in rocks of the Trans-Hudson Orogen. The company is actively exploring for new deposits on their property, but are wanting to improve their understanding of how the gold deposits and the surrounding rocks formed. In detail, the project will form part of four M.Sc. and four B.Sc. theses at the University of Saskatchewan, and will use analytical techniques not routinely available to minerals companies. The focus of the project will be two-fold. One will be to characterize the volcanic and intrusive igneous rocks that are found within the Fisher exploration property, and compare them with the rocks that host the historical, and active mines on the SSR Mining property. The other will be to determine the distribution of gold and other elements in minerals in quartz veins that contain high-grade gold, as well as the composition of the hydrothermal fluids from which the veins formed. In the end, we will have a better understanding of the origin of the rocks and gold-bearing quartz veins in the region, and the actual location of the gold and associated metals in the minerals in the deposit. The latter will assist in improving gold recovery and the remediation of the mine sites in the future, whereas the former will help to focus exploration on the rock types with the best chance of hosting new deposits. Exploration, mining, and environmental monitoring activity will spark economic activity in this isolated part of the Canadian Shield in northern Saskatchewan, and lead to training and economic opportunities for northern communities.

加拿大的大多数历史悠久的黄金矿床都与超过25亿年历史的加拿大盾牌的岩石有关。这些被称为“造基金沉积物”，因为它们在古老的山区建筑活动中形成。在加拿大中央和北极加拿大的加拿大盾牌中也发现了类似的黄金沉积物，但与年轻的（约18亿年历史的山带）相关，称为跨性造成山地造山机。但是，这些沉积物的起源尚未得到充分了解，因此可能会毫无疑问。 SSR Mining Inc.，该公司已开发了该提案，经营萨斯喀彻温省唯一的金矿，并位于跨性造山机的岩石中。该公司正在积极探索其财产的新存款，但希望提高对黄金存款和周围岩石的形成方式的理解。详细说明，该项目将构成四个M.Sc的一部分。和四个B.Sc.萨斯喀彻温大学的这项话题将使用矿物公司常规可用的分析技术。该项目的重点将是两个方面。一种将是描述Fisher Exploration属性中发现的火山和侵入性火山岩石，并将它们与拥有历史悠久的岩石进行比较，并在SSR采矿特性上进行了活跃的地雷。另一个是确定含有高级金的石英静脉中的黄金和其他元素的分布，以及从中形成静脉的水热液的组成。最后，我们将更好地理解该地区岩石和含金石英脉的起源，以及矿物质中黄金和相关金属的实际位置。后者将来将有助于改善黄金恢复和对矿场的修复，而前者将有助于将探索重点放在岩石类型上，并有最好的机会托管新的存款。勘探，采矿和环境监测活动将激发萨斯喀彻温省加拿大盾牌的孤立部分的经济活动，并为北部社区带来培训和经济机会。
