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.

该项目将调查雷霆湾北部（TBN）火成岩杂岩（1.1 Ga中大陆裂谷的一部分）的矿化侵入体，并将其与贫瘠和弱矿化侵入体进行比较。该项目将培养三名理学硕士，三名HBSc和一名PDF完成一项综合研究计划，以完成三个关键目标。在接下来的三年里，该项目将通过以下方式调查雷霆湾北部物业的侵入性单元：1）描述在该财产内发现的各种侵入单位的岩石学、地球化学和地质年代学特征，2）描述逃逸湖和当前湖侵入体硫化物矿化的地球化学和岩相学特征; 3）整合新的矿物学和地球化学数据，为该属性建立一个整体模型，并建立侵入体内部和周围的矿化矢量，这将有助于勘探更多的Ni-Cu-PGE和块状硫化物资源。本研究将利用基础地质填图和测井，结合传统和最先进的分析技术，以表征TBN矿化的侵入历史和共生。通过这样做，我们将培养年轻的研究人员在地球科学领域取得成功所需的关键技能，无论是在学术界，政府还是工业界。本研究产生的数据将用于开发Escape Lake和雷霆湾北部矿床的模型，清洁空气金属公司可以使用这些模型来加强他们的勘探工作，并有望导致矿产生产。该项目将大大有助于我们了解在岩浆Ni-Cu-PGE系统中形成高品位区的过程，并开发可供加拿大公司应用的工具，以帮助产生未来的发现。新矿产资源的发现和开发对加拿大经济的福祉至关重要，该项目将提高这一进程的效率。
