Magris Performance Materials operates both the Niobec niobium mine (steel alloying) and a significant tantalum processing business acquired through Global Advanced Metals. Tantalum is the critical metal inside tantalum capacitors found in every smartphone, aerospace avionics system, and military electronics platform. The same Magris entity that gives North America its only domestic niobium supply (for HSLA steel in bridges and pipelines) also processes tantalum powders for the electronics supply chain — connecting infrastructure steel and consumer electronics to a single privately-held specialty metals company backed by Singapore sovereign capital.

The Niobec mine at Saint-Honore, Quebec was discovered in the 1960s during mineral exploration and operated under multiple owners (Cambior, then IAMGOLD) before Magris Resources acquired it in 2015 for $530 million alongside investors CEF Holdings and Temasek (Singapore's sovereign wealth fund). Niobec is the only niobium mine outside Brazil and functions as the Western world's sole domestic diversification option against the CBMM/CMOC duopoly that controls Brazilian deposits.
