Toronto-based Sigma Lithium Corp., which operates lithium mines in Brazil, led the pack, nearly doubling in value over the three months to December 31, 2025. Its performance testified to strong execution—net revenues rose 69% quarter-over-quarter and 36% year-over-year—but also to resumed investor interest in lithium, a key component in rechargeable batteries essential for the energy transition.
Aris Mining of Vancouver came in a distant second, with a 61.9% return, followed by Toronto-headquartered Discovery Silver Corp., at 58.9%. Aris is a miner of gold in Colombia that counts mining tycoons Frank Giustra, Ian Telfer, and Neil Woodyer among its shareholders; it consolidated its stake in the Soto Norte property during the quarter and was added to the S&P/TSX Composite in September.
