Generation Mining has landed a C$200m (US$141m) debt commitment from the Canada Infrastructure Bank to push its Marathon copper-palladium project toward construction, joining a broader financing package that already includes senior lenders, a streaming deal and leased equipment facilities.
The Canada Infrastructure Bank’s pledge arrives as a targeted subordinated loan plus a contingency standby facility designed to de-risk construction financing. That structure aims to bridge development costs while providing cover against potential overruns when the site moves into the heavy-build phase.
The specific terms announced split the CIB backing into C$110m of subordinated debt for development and construction, with a further C$90m held as a standby facility for cost overruns. Those pieces are meant to slot under the project’s senior financing and sit ready to shore up the budget if unexpected expenses arise during construction.
This marks the CIB’s first direct play in Ontario’s critical minerals space and signals public-sector interest in securing domestic supplies of copper and palladium. The bank’s involvement is framed as strategic support for minerals tied to electrification and industrial supply chains.
Generation Mining’s chief executive framed the deal as fitting the CIB’s purpose and validating the project’s commercial case. “The CIB’s mandate to catalyse private-sector investment in critical infrastructure makes it a natural partner for Generation Mining.
“The commitment further validates the strength of the Marathon project’s economics, its strategic importance and its significance as a future North American producer of copper and palladium – two metals essential to the energy transition.” Those exact words underline what management sees as both economic and policy alignment behind the financing.
Beyond the CIB financing, Generation Mining has already assembled a near-complete funding package, with approximately C$969m lined up in total financing commitments to date. That total combines a senior debt facility, streaming income, and equipment leasing arrangements to cover most of the capital needs for the project.
The senior debt element totals about US$310m and is backed by Export Development Canada alongside international lenders ING Capital and Société Générale. Meanwhile, a C$200m streaming agreement with Wheaton Precious Metals provides upfront cash linked to future metal deliveries, and equipment leasing facilities account for roughly C$145m of additional funding capacity.
The CIB arrangement remains subject to final documentation and an inter-creditor agreement that will set out rights and priorities between lenders and other stakeholders. Those closing mechanics are standard for project finance deals and the company expects customary covenant and security arrangements to be put in place.
Assuming the remaining pieces fall into place, construction at Marathon is slated to kick off in the second half of 2026. That timeline depends on completion of project financing and the finalization of surety and equity arrangements so the site can transition from permitting and engineering into heavy construction.
Marathon is described by the company as a large undeveloped deposit with an anticipated mine life of around 13 years once in production. Management continues to negotiate with surety providers and potential equity partners to close out the financing package and move toward the build decision.
