TORONTO--(BUSINESS WIRE)--Generation Mining Limited (TSX: GENM; OTCQB: GENMF) (“Gen Mining” or the “Company”) is pleased to announce positive results on the updated Feasibility Study (“2025 FS” or the “Feasibility Study”) for the Marathon Copper-Palladium Project (the “Project”) located near the Town of Marathon in Northwestern Ontario. All dollar amounts are in Canadian dollars (“$” or “C$”) unless otherwise stated. All references to “Mlbs” are to millions of pounds and “Moz” are to millions of troy ounces and “koz” are to thousands of troy ounces.
The 2025 FS incorporates the results of the Project optimization work reported by the Company in a news release entitled “Generation Completes Optimization Work for the Marathon Project with Improved Mine Plan and Reduced Capex” issued on November 20, 2024, which focused on two key aspects: 1) optimization of the mine plan to maximize metal production and defer waste stripping in the early years of operations in order to improve early cash flows and reduce the payback period (“Mine Plan Optimization”); and 2) optimization of the process plant design and layout, including sizing of key equipment, plant footprint and foundations, in order to reduce the initial Project capital costs (“Initial Capital Optimization”, and together with the Mine Plan Optimization, the “Optimization Work”).
The Optimization Work has now been further updated to incorporate changes to Mineral Resources, Mineral Reserves, the Life-of-Mine (LOM) mining plan and operating and capital costs, using the same metal price assumptions which formed the basis of the November 20, 2024 news release.
The 2025 FS was prepared by Ausenco Engineering Canada ULC (“Ausenco”), along with contributions from Moose Mountain Technical Services (“MMTS”), Knight Piésold Ltd. (“KP”), P&E Mining Consultants Inc. (“P&E”), and JDS Energy and Mining, Inc (“JDS”).
The 2025 FS outlines the operation of an open pit mine and process plant over a mine life of 12.5 years and replaces the Company’s previous feasibility study entitled “Amended Feasibility Study Update, Marathon Palladium & Copper Project, Ontario, Canada” dated May 31, 2024.
Jamie Levy, President and CEO of the Company, commented, “The updated Feasibility Study for the Marathon Copper-Palladium Project clearly underscores its potential to be Ontario’s next producing critical mineral mine. The project not only benefits from a strong commodity mix of critical metals but also stands as a strategic Canadian response to growing threats in the global mineral supply chain.
The Marathon Project’s significant exposure to copper and palladium positions it as a uniquely attractive opportunity in the critical mineral space in North America. With copper facing long-term supply constraints and persistent supply risks from the primary palladium producers in Russia and South Africa, the Marathon Project is well positioned to support North American and European smelters. The Project’s advanced development and permitting is also a key differentiator, which positions us to bring metal to market faster than any other North American copper project not yet in construction.”
Kerry Knoll, Executive Chairman of the Company commented, “Anticipating the final permit approvals from the provincial government in the near future, the Marathon Project is on track to become the next major shovel-ready critical metal project in Ontario and Canada. The potential backing from provincial and national critical metal funds, combined with support from banks, private equity, institutional investors, and retail shareholders, provides a strong foundation for securing full financing in the near term.”
Economic Analysis
The updated Feasibility Study underscores the continued economic robustness of the Marathon Project with an after-tax NPV6% of $1.07 billion, IRR of 28% and 1.9 year payback period based on the 3-yr trailing average metal prices as of November 1, 2024.
The following table presents the key outputs of the economic analysis for the 2025 FS using 3-year trailing average metal prices, together with the same analysis performed using spot and consensus metal prices, and foreign exchange rate assumptions:

Non-IFRS Financial Measures and Other Measures
The Company has included certain financial measures in this news release, including initial capital cost, operating costs, AISC, and Pre-Tax and After-Tax Cash Flows, which are not measures recognized under IFRS and do not have a standardized meaning. These non-IFRS financial measures are included in this document because these statistics are measures that management will use to monitor future financial performance, and to plan and assess the overall effectiveness and efficiency of future mining operations. The Company does not have historical non-IFRS financial measures nor historical comparable measures under IFRS, and therefore the foregoing prospective non-IFRS financial measures may not be reconciled to the nearest comparable measures under IFRS. Non-IFRS measures do not have any standardized meaning prescribed under IFRS, and therefore, they may not be comparable to similar measures employed by other companies. The data presented is intended to provide additional information and should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS.
Non-IFRS performance measures used herein are defined as follows:
- Initial Capital includes all costs incurred from the effective date of the 2025 FS (excluding historical sunk costs) until the point where commercial production is achieved, including expenses related to engineering, equipment purchase and installation, process plant and mine infrastructure construction, and any other costs associated with putting the Project into operations.
- Operating Costs includes mining, processing, general and administrative and other, concentrate transportation costs, treatment and refining charges, and royalties. Costs related to the Wheaton PMPA are excluded.
- AISC includes Operating Costs, closure and reclamation costs, and sustaining capital.
- Pre-tax Cash Flow includes total revenue less Operating Costs, working capital adjustments, equipment financing, initial capital, sustaining capital, closure costs. Costs related to the Wheaton PMPA are included.
- After-tax Cash Flow includes Pre-tax Cash Flow less income taxes payable.
The Marathon Project is a polymetallic deposit. For purposes of estimating the Company’s anticipated costs and future financial performance, the Company discloses certain financial measures herein based on estimates of future palladium equivalent (“PdEq”) and copper equivalent (“CuEq”) metal production. The Company’s estimated PdEq and CuEq are calculated using the payable metals estimates derived from the Company’s LOM, as follows:
- Palladium Equivalent ounces uses the formula PdEq oz = Pd oz + (Cu lb x 4.00 US$/lb + Pt oz x US$950/oz + Au oz x US$2000/oz + Ag oz x US$24.00/oz) / US$1525 Pd/oz.
- Copper Equivalent pounds uses the formula CuEq lbs = Cu lbs + (Pd oz x US$1,525/oz + Pt oz x US$950/oz + Au oz x US$2000/oz + Ag oz x US$24.00/oz) / US$4.00 Cu/lb.
Information Concerning Estimates of Mineral Reserves and Resources
The Mineral Reserve and Mineral Resource Estimates in this press release have been disclosed in accordance with NI 43-101, which differs from the requirements of the U.
