Closure Plan Approved for Generation Mining’s Marathon Palladium-Copper Project – Major Milestone Met

TORONTO–(BUSINESS WIRE)–$GENM #copper–Generation Mining Limited (TSX:GENM)(OTCQB: GENMF)(“Gen Mining” or the “Company”) is pleased to announce that the province of Ontario has accepted and filed the Closure Plan for the Marathon Palladium-Copper Project. This represents another major milestone in the permitting process for the Marathon Palladium-Copper Project.

Jamie Levy, President and Chief Executive Officer of the Company said, “The approval of our Closure Plan for the Marathon Palladium-Copper Project is the conclusion of months of work to define the social, environmental, and technical elements of the Closure Plan to achieve the land use envisioned for the property after mining concludes, including establishing a self-sustaining ecosystem, re-establishing access through the area for traditional land use and providing future economic development opportunities. The Marathon Palladium-Copper Project is a valuable and strategic asset containing critical metals that are needed to support emissions controls and the transition to a greener economy. We are grateful for the incredible stakeholder support including the First Nation community of Biigtigong Nishnaabeg and the Town of Marathon, and the Ontario government.”

Along with the approval of the Closure Plan, the Company continues to make significant progress on obtaining the permits for the Project. In August 2023 we received our Endangered Species Act Permit and in September the Company received the Environmental Compliance Approval issued by the Ministry of Environment, Conservation and Parks for air and noise emissions for the Marathon Project. Additional permits and approvals are expected to be received during the balance of 2023.
