How Canada’s biggest iron project is almost unknown
MINING.COM· 2026-03-07 16:35
Core Viewpoint - Lac Otelnuk, owned by MetalQuest Mining, is the largest iron deposit in North America with 4.9 billion tonnes of proven and probable reserves, potentially making it the world's second largest by contained reserves [2][4]. Project Overview - The project has a 68% iron concentrate grade, making it a candidate for high-purity iron supply, which is critical for low-emission steelmaking [3][16]. - The feasibility study from 2015 indicates a post-tax net present value of $5.24 billion and an internal rate of return of 13% over a 30-year mine life [9]. - Capital costs are estimated at approximately $14.2 billion, positioning it among the most expensive mining projects globally [9][10]. Infrastructure and Development Challenges - The proposed open pit dimensions are 11.6 km long and 2.8 km wide, but the depth of 130 meters is considered shallow compared to other major mines [8]. - Infrastructure challenges include the project's remote location, requiring innovative solutions such as slurry pipelines for ore transport, although traditional road and rail methods are preferred [11][10]. Strategic Partnerships - MetalQuest is actively seeking a major partner to finance the project, having engaged with several large companies, particularly in Japan [12][14]. - There are at least six to eight companies that have signed confidentiality agreements and are awaiting the gap study results [13]. Future Outlook - The company plans to conduct further studies, including a new feasibility study by 2030, with potential production starting in 2035 if a major partner is secured [19]. - Despite the designation of high-purity iron as a critical mineral by the Canadian government, direct support has not yet been received [19][20].
