Site work for a mixed-use development in Marathon, Ontario. Completed plans call for site work for a industrial development; and road / highway.
The Marathon project is located near the town of Marathon on the north shore of Lake Superior, in northwestern Ontario, approx. 10 km from the Trans-Canada Highway. The project contains one of North America's largest undeveloped platinum group metal mineral resources. The Marathon Project involves the construction, operation, decommissioning, and remediation of 3 open pits to produce copper concentrate, consisting primarily of copper, palladium and platinum, critical minerals, an onsite ore processing facility, a 115 kV transmission line, an access road, a mine rock storage area, a process solids management facility, and a water management system, amongst other infrastructure. The project is expected to produce 166,000 ounces of palladium per year and 41 million pounds of copper per year. Over the approx. 13-year life-of-mine, Marathon is projected to produce over 2.1 million ounces of palladium, 517 million pounds of copper, 485,000 ounces of platinum, 158,000 ounces of gold, and 3.16 million ounces of silver in payable metals. The Marathon Project would be one of North America's few palladium producers and a key producer of copper. TIMELINE: Construction is underway. The early works program is expected to run through Q4 2026 and well into 2027. *Project has been estimated at approx. 992 million.
