Marathon Copper-Palladium Project Feasibility Study: C$1.07B NPV, 27.6% IRR
Generation Mining Limited's Marathon Copper-Palladium Project in Ontario, Canada has a Feasibility Study outlining an after-tax NPV of C$1.07B, an after-tax IRR of 27.6%, and initial capital of C$992M. The mine plan runs 13 years at about 120 M lbs CuEq per year.
Generation Mining Limited's Marathon Copper-Palladium Project has reported Feasibility Study results for the copper/palladium project in Ontario, Canada. The study headlines an after-tax net present value of C$1.07B at a 6% discount rate. It reflects Generation Mining Limited's (GENM.TO) latest disclosed economics for the asset.
Economics. The after-tax NPV is C$1.07B using a 6% discount rate. After-tax IRR is 27.6%. Initial capital expenditure is estimated at C$992M, with life-of-mine sustaining capital of C$565M. The study models a payback period of 1.9 years. All-in sustaining costs are pegged at 781 USD/oz PdEq. Economics are based on Pd US$1,525/oz, Cu US$4.00/lb, Pt US$950/oz, Au US$2,000/oz, Ag US$24/oz (NSR cut-off inputs). Marathon Resource metal prices: US$1,550/oz Pd, US$4.250/lb Cu, US$1,100/oz Pt, US$2,300/oz Au, US$27/oz Ag..
Production and mine plan. The project envisions an open-pit operation. Life of mine is 13 years. Average annual production is approximately 120 M lbs CuEq. The open-pit strip ratio is 2.8.
Resources and ownership. Royalties and streams: C$240 million Wheaton Precious Metals Stream (Wheaton PMPA); stream excluded from AISC.

A US$174M micro-cap proposing a C$992M build is the whole story in one ratio: the cheque is roughly 4.2x the company’s entire equity value. That is not a financing gap a balance sheet closes; it is a transaction. The realistic paths are a strategic partner writing a large equity cheque, a streaming or royalty deal on the palladium and copper stream, or outright M&A. Each path carries the same implication for existing holders: substantial dilution or a change of control premium that caps the upside the NPV implies. The project economics are the supporting act, not the lead.
The numbers support that framing. After-tax NPV of C$1.07B is about 4.5x the market cap, which cuts two ways: either the market has not priced a permitted, shovel-ready feasibility study in Ontario, or it is pricing the financing risk and the dilution required to build it. The 27.6% after-tax IRR clears the 20% hurdle a higher-risk junior with little else in the portfolio needs to attract project finance, and it ranks in the lower half of the 344 tracked projects. The 1.9-year payback is genuinely fast and de-risks the early years, but it does not solve the funding question. The 6% discount rate is a reporting convention and not an investment signal.
The study itself is the most reliable stage this asset will reach: feasibility-level, build-ready, in a mining-friendly jurisdiction, with a 13-year mine life. The metal price deck is the study’s own assumption, and the returns stand or fall on those inputs holding. The single question that decides this project is not whether the mine works, it is who writes the C$992M cheque and what they demand in return for doing so.
