Generation Mining Receives Key Approval From the Federal Government

Generation Mining Ltd. (TSX:GENM, OTCQB: GENMF) ("Gen Mining" or the "Company") is pleased to announce the federal government has approved amendments to Schedule 2 of the Metal and Diamond Mining Effluent Regulations ("Schedule 2") for the Marathon Palladium-Copper Project (the "Marathon Project"). This approval will allow for the construction of specific water management structures and operation of key infrastructure for the Marathon Project.

Following approval by the Governor in Council, on the recommendation of the federal Minister of Environment and Climate Change, the regulatory amendment adding the specified Marathon Project waterbodies and geographic areas encompassing water bodies to Schedule 2 was published in the Canada Gazette, Part II, on July 31, 2024. Receipt of the few remaining provincial and federal approvals and permits required for construction is expected in the coming months.

"We are now on the cusp of having one of the only permitted copper and PGM projects in North America that can be constructed and brought into operation once we obtain the requisite financing. The Marathon Project is one of the most advanced critical mineral projects in Canada, and this government approval represents another milestone on the path to developing Canada's next copper and palladium mine," said Jamie Levy, President and Chief Executive Officer of the Company. "The Marathon Project will support the economic growth and competitiveness of Canada and Ontario, as well as provide socio-economic benefits for Indigenous and local communities. The Company is proud to be part of this generational opportunity for Canada's economy and net-zero future."

Ruben Wallin, VP Sustainability of the Company also noted: "The Marathon Project has been designed to ensure critical mineral development will occur in a manner which is sustainable, incorporates best practices in environmental and social governance, and reflects the knowledge shared by Indigenous communities. This milestone demonstrates that permitting of critical mineral projects in Canada can occur in a timely and efficient manner when the company, government and Indigenous communities work collaboratively."
