Copper, gold, and other critical elements (rare earth elements, fluorine) are essential for the global transition to a green economy and renewable energy. Current and pending demand for these metals will far exceed supply from current production and those obtained from recycling. Thus, to meet global demands for these critical metals, new metal resources will need to be found and more efficient methods of exploration and development will be required - this project addresses both of these challenges. The proposed research focuses on copper, gold, rare earth elements, and fluorite found in magmatic rocks in Baie Verte, Springdale, and related regions in the central Newfoundland Appalachians. The work will involve studying the relationships between magmatism, the role of faults and ancient volcanoes, and how they collectively influenced the movement of metal bearing fluids, deposition of metals, and interaction of these fluids with rocks in the crust. The project will involve fieldwork and use the chemistry of rocks and minerals to determine the geological environment, age of mineralization and how the mineralization formed. In addition, the project will use geological, geochemical, mineral chemical, and machine learning methods to decipher potential geological environments with metal potential and how close one is to mineralization. The results will create new knowledge, models, and exploration and development workflows that will enable more efficient exploration for metals in the Newfoundland Appalachians and similar geological environments globally. In addition, the research team will train three Masters-level graduate students and field assistants (including Indigenous participants, if possible) who will obtain workplace skills that will be easily exportable to employment in the geosciences sector, where these skills are in great demand.

铜、金和其他关键元素（稀土元素、氟）对于全球向绿色经济和可再生能源的过渡至关重要。目前和未来对这些金属的需求将远远超过目前生产和回收的供应。因此，为了满足全球对这些关键金属的需求，将需要找到新的金属资源，并需要更有效的勘探和开发方法-该项目解决了这两个挑战。拟议的研究重点是铜，金，稀土元素和萤石中发现的岩浆岩在贝韦尔特，斯普林代尔，和相关地区在中部纽芬兰阿巴拉契亚山脉。这项工作将涉及研究岩浆活动，断层和古火山的作用之间的关系，以及它们如何共同影响含金属流体的运动，金属的沉积以及这些流体与地壳中岩石的相互作用。该项目将涉及实地考察，并利用岩石和矿物的化学性质来确定地质环境、矿化年龄以及矿化如何形成。此外，该项目将利用地质、地球化学、矿物化学和机器学习方法来破译具有金属潜力的潜在地质环境以及与矿化的距离。研究结果将创造新的知识、模型以及勘探和开发工作流程，使纽芬兰阿巴拉契亚山脉和全球类似地质环境中的金属勘探更加有效。此外，研究小组将培训三名硕士级研究生和现场助理（如有可能，包括土著参与者），他们将获得易于出口到地球科学部门就业的工作技能，这些技能需求量很大。
