This project will investigate the mineralized intrusions of the Thunder Bay North (TBN) igneous complex, part of the 1.1 Ga Midcontinent Rift, and compare them to barren and weakly mineralized intrusions. The project will train three MSc, three HBSc and one PDF to complete an integrated program of research to complete three key opjectives. Over the next three years the project will investigate the intrusive units of the Thunder Bay North property by: 1) Characterising the petrology, geochemistry and geochronology of the various intrusive units found within the property, 2) Characterising the geochemistry and petrography of the sulfide mineralisation of the Escape Lake and Current Lake intrusions and 3) Integrating new mineralogical and geochemical data to build a holistic model for the property and establish vectors towards mineralization within and around the intrusions that will aid in exploration for addition Ni-Cu-PGE and massive sulfide resources. This study will utilize fundamental geological mapping and logging combined with traditional and state-of-the-art analytical techniques to characterize the intrusive history and paragenesis of the mineralization at TBN. By so doing we will train young researchers in the key skills necessary for a successful career in the geosciences whether in academia, government or industry.The data generated in this study will be used to develop a model(s) for the Escape Lake and Thunder Bay North deposits that Clean Air Metals can use to enhance their exploration efforts, and hopefully lead to mineral production. This project will contribute significantly to our understanding of the processes that form high grade zones within magmatic Ni-Cu-PGE systems and develop tools that can be applied by Canadian companies to aid in generating future discoveries. The discovery and development of new mineral resources is critical to the well-being of Canada's economy and this project will lead to greater efficiencies in that process.

该项目将调查 Thunder Bay North (TBN) 火成岩杂岩（1.1 Ga 中部大陆裂谷的一部分）的矿化侵入体，并将其与贫瘠且弱矿化的侵入体进行比较。该项目将培训三名理学硕士、三名HBSc 和一名PDF 人员，以完成一项综合研究计划，以完成三个关键目标。在接下来的三年中，该项目将通过以下方式调查 Thunder Bay North 矿区的侵入单元：1) 描述该矿区内发现的各种侵入单元的岩石学、地球化学和地质年代学特征，2) 描述硫化物矿化的地球化学和岩石学特征逃逸湖和当前湖入侵的情况，以及 3) 整合新的矿物学和地球化学数据，为该矿区建立一个整体模型，并建立矿区内部和周围矿化的向量侵入将有助于勘探额外的 Ni-Cu-PGE 和大量硫化物资源。这项研究将利用基础地质测绘和测井，结合传统和最先进的分析技术来描述 TBN 矿化的侵入历史和共生特征。通过这样做，我们将培训年轻研究人员掌握在学术界、政府或工业界取得成功的地球科学职业所需的关键技能。本研究中生成的数据将用于开发 Escape Lake 和 Thunder 的模型Clean Air Metals 可以利用北湾矿床来加强勘探工作，并有望实现矿物生产。该项目将极大地促进我们对岩浆 Ni-Cu-PGE 系统内形成高品位带的过程的理解，并开发可供加拿大公司用来帮助未来发现的工具。新矿产资源的发现和开发对于加拿大经济的福祉至关重要，该项目将提高这一过程的效率。
