This Alliance partnership between the University of Saskatchewan and Profile Products is designed to evaluate and test soil amendments for mine covers in cold regions. Mine covers are crucial to mine closure where constructed slopes store and release water to the environment and prevent water and oxygen ingress into waste rock and mine tailings. We will test a number of new soil amendments produced by Profile Products-the first such testing of soil amendments on mine covers in controlled, cold, laboratory conditions. Such evaluation and testing of soil amendments for mine covers is an economically and environmentally important topic to Canada. We estimate that for mine covers and their life-cycle represent about $25 million in "demand" and ~$500 million in "risks" exist in the next 10-20 years. This project will test a number of amendments designed to stimulate vegetation growth and improve hydrological functioning of created mine covers. Following the project's completion, Profile Products will invest to advance the results in Canada. The work will last for one year and result in the training of one Postdoctoral Fellow and two Research Technicians. Equity, diversity and inclusion are interwoven into the training plan and McDonnell has an unusually strong track record of diversity in his lab with 54% females (in a field of 28% female participation overall) and diverse international membership and ethnic diversity from Canada, Brazil, China, Australia, Mexico, USA, China and the UK. Diversity of ideas, genders, backgrounds and ethnicity is his goal for team building for research excellence-described in his 2016 paper in Science magazine titled "Orchestrating a Powerful Group". McDonnell has visited the Six Nations First Nation in Ontario and spoken with Mr. V. Natomagan, Executive Director at Kineepik Metis Local who heads the First Nations engagement for Cameco-all with an aim of filling one of the technician positions on this project with a First Nations worker.

萨斯喀彻温大学和 Profile Products 之间的联盟合作伙伴关系旨在评估和测试寒冷地区矿井覆盖层的土壤改良剂。矿井盖对于矿井关闭至关重要，建造的斜坡可以储存水并将其释放到环境中，并防止水和氧气进入废石和尾矿。我们将测试 Profile Products 生产的多种新型土壤改良剂，这是在受控、寒冷的实验室条件下对矿井盖土土壤改良剂进行的首次此类测试。矿井覆盖土壤改良剂的此类评估和测试对于加拿大来说是一个经济和环境上重要的话题。我们估计，未来 10-20 年内，矿井覆盖及其生命周期将带来约 2500 万美元的“需求”和约 5 亿美元的“风险”。该项目将测试一系列旨在刺激植被生长和改善所建矿井盖的水文功能的修正案。 该项目完成后，Profile Products 将进行投资以推进加拿大的成果。这项工作将持续一年，培训一名博士后研究员和两名研究技术人员。公平、多样性和包容性融入到培训计划中，麦克唐纳在其实验室中拥有异常强大的多样性记录，其中女性比例为 54%（整个领域女性参与率为 28%），并且拥有来自加拿大、巴西、中国、澳大利亚、墨西哥、美国、中国和英国的多元化国际成员和种族多样性。 思想、性别、背景和种族的多样性是他为卓越研究而建设团队的目标——他在 2016 年《科学》杂志上题为“编排一个强大的团队”的论文中对此进行了描述。麦克唐纳访问了安大略省的六族原住民，并与 Kineepik Metis Local 的执行董事 V. Natomagan 先生进行了交谈，他负责 Cameco-all 的原住民项目，旨在用一名原住民工人填补该项目的一个技术人员职位。
