Generation Mining has secured the final C$340 million needed to complete the approximately C$1.3 billion financing package for construction of its Marathon copper-palladium project in northwestern Ontario.

With the funding structure now in place, the company has the financing needed to move the fully permitted project toward construction. Generation Mining’s board is expected to consider a final investment decision once the latest transactions are completed.

Federal Capital Anchors Final Funding

A significant part of the latest financing comes from Canada Growth Fund, which is committing about C$140 million to Generation Mining through a combination of equity and convertible debt.

Canada Infrastructure Bank is also participating in the financing, while Wheaton Precious Metals and Glencore are involved in the equity funding.

The federal participation gives Marathon significant public-sector backing at a stage when mine developers often struggle to secure the full capital needed to move from permitting to construction.

Marathon Moves Closer to Construction

The financing shifts Marathon’s immediate focus from capital raising to project execution.

Generation Mining has spent several years advancing the deposit through feasibility work, permitting, and financing. An updated feasibility study released in March 2025 outlined an open-pit mine and processing operation with a mine life of approximately 12.5 years.

The project sits near the town of Marathon, roughly 215 kilometres east of Thunder Bay, and contains a substantial platinum-group-metal resource alongside copper.

Marathon is expected to produce palladium, copper, platinum, gold, and silver, giving the project exposure to both precious metals and minerals used in industrial and energy-related supply chains.

Copper and palladium are expected to contribute most to the project’s strategic importance in Canada.

Glencore Deal Adds Domestic Processing Route

Generation Mining has also reached terms with Glencore Canada Corp. for the sale of concentrate produced at Marathon.

The planned concentrate would contain copper along with palladium, platinum, gold, and silver. The material is expected to enter Canadian processing facilities, including Glencore’s Horne smelter in Rouyn-Noranda, Quebec, and the Canadian Copper Refinery in Montreal East.

That arrangement gives Marathon a clear path from mine production to Canadian smelting and refining capacity and links the Ontario project to an established domestic metals-processing network.

Final Investment Decision is Next

The remaining corporate milestone is the final investment decision.

Once the current financing transactions close, Generation Mining’s board is expected to determine whether to proceed with construction.

That decision would move Marathon from a financed and permitted development project into the construction phase, bringing Generation Mining closer to establishing a new Canadian source of copper and palladium in northwestern Ontario.
