Did you know2023
CMOC is simultaneously the world's largest cobalt miner (via DRC Tenke Fungurume and Kisanfu) AND the operator of North America's only niobium mine (Niobec, Quebec). These two mining positions serve completely separate critical material supply chains: cobalt (DRC) flows into EV battery cathodes for clean energy transition; niobium (Quebec) flows into high-strength automotive steel for vehicle lightweighting AND into NbTi superconducting wire for clinical MRI magnets. The CMOC positions create a Chinese company dependency in both the EV battery upstream AND the medical imaging infrastructure upstream — and the 2022-2023 DRC government dispute demonstrated that CMOC's DRC cobalt can be supply-constrained by a DRC government decision. A single Chinese mining conglomerate controls inputs for: EV batteries (cobalt), automotive lightweighting (niobium), and MRI machine superconducting magnets (niobium). The April 2025 Chinese critical mineral export controls targeted different metals (rare earths) but CMOC's portfolio demonstrates the breadth of Chinese mining equity in Western-essential critical minerals.

China Molybdenum (CMOC) owns Niobec mine in Saint-Honore, Quebec — the only significant niobium mine in North America, controlling ~8% of global niobium supply. The strategic geography is notable: CMOC (a Chinese company) owns the only North American niobium mine, making US and Canadian access to domestically mined niobium contingent on a Chinese-controlled operation. Canada approved the CMOC acquisition of Niobec in 2011 — before CFIUS/national security screening of Chinese mineral acquisitions became standard practice. Niobium's end uses span: HSLA steel (automotive lightweighting, North American vehicles use ~300g niobium per car on average), superconducting magnets (NbTi wire in all clinical MRI machines and CERN particle accelerators), and emerging niobium-oxide battery anode research. Brazil's CBMM dominates global supply at ~85%, but Niobec in Quebec is the sole North American source. If geopolitical conditions required substituting North American niobium supply, no alternative North American mine is currently operational.
