Generation Mining Continues with Project Optimizations for the Marathon Palladium-Copper Project

TORONTO–(BUSINESS WIRE)–$genm #Copper–Generation Mining Limited (TSX:GENM, OTCQB: GENMF) (“Gen Mining” or the “Company”) continues to advance the Marathon Palladium-Copper Project in Northwestern Ontario through project design optimizations. As the Company works to complete the permitting process and obtain the necessary government approvals to commence construction, it has engaged a construction-focused engineering firm to support design optimizations for the Project. The intent is to improve on the designs for Project constructability, to decrease initial capital costs, and to reduce the operating-phase costs.

The work will include optimizing design, supply and construction strategies with the assistance of original equipment manufacturers, contractors and construction consultants, to help improve the overall cost and construction efficiency of designs. The focus will be on ensuring that the plant and infrastructure designs are ‘fit-for-purpose’ and leverage the improved understanding of actual site conditions to reduce the quantities of building steel and foundation concrete.

The Company is also concurrently evaluating alternative pit sequencing options that further exploit the benefit of the ore body’s proximity to surface. This mine planning optimization is intended to produce higher cash flows in the early years of production by maximizing plant feed grades and reducing the initial stripping requirements until later in the mine life.

Jamie Levy, President and CEO says, “I am confident this optimization work will further enhance the economics and construction readiness of the Marathon Project. We have continued to advance our permitting program and are making great strides towards having all necessary government permits and approvals for the construction phase. The goal of this work is ultimately to improve upon the initial capital requirements and cash flows from operations in the early years following start-up, without impacting the fundamentals of the design.”

The work has commenced as of late-April and will continue throughout the coming months. The Company will provide further updates on the optimization initiatives when completed.

About Generation Mining Limited

Gen Mining’s focus is the development of the Marathon Project, a large undeveloped palladium-copper deposit in Northwestern Ontario, Canada. On May 31, 2024, the Company filed an Amended Feasibility Study Update for the Marathon Project with an effective date of December 31, 2022 (the “Feasibility Study”).

The Feasibility Study estimates a Net Present Value (using a 6% discount rate) of C$1.16 billion, an Internal Rate of Return of 25.8%, and a 2.3-year payback. The mine is expected to produce an average of 166,000 ounces of payable palladium and 41 million pounds of payable copper per year over a 13-year mine life (“LOM”). Over the LOM, the Marathon Project is anticipated to produce 2,122,000 ounces of palladium, 517 million lbs of copper, 485,000 ounces of platinum, 158,000 ounces of gold and 3,156,000 ounces of silver in payable metals. For more information, please review the Feasibility Study filed under the Company’s profile at www.sedarplus.ca or on the Company’s website at https://genmining.com/projects/feasibility-study/.

The Marathon Property covers a land package of approximately 26,000 hectares, or 260 square kilometres. Gen Mining owns a 100% interest in the Marathon Project.
