Underscoring sustained investor confidence in Boston Metal’s team, technology, and dual-business unit strategy, funds from the note will support the deployment of the second phase of its critical metals plant in Brazil, slated to come online in mid-2026, and reinforce the company’s continued development of its green steel solution.
“Boston Metal’s unique process makes steel production efficient, cost-effective and more sustainable,” said Laurel Buckner, VP of ventures at BHP. “The investment in Boston Metal continues to drive BHP Ventures’ support of game-changing technologies that drive innovation for the broader industry.”
This infusion of capital comes on the heels of multiple strategic advancements for the company. Boston Metal recently welcomed Eduardo Bartolomeo—former CEO of Vale and a globally respected metals executive—to its board of directors, reinforcing the company’s leadership bench as it scales for its next phase of growth.
In Brazil, Boston Metal’s molten oxide electrolysis (MOE) critical metals business is expected to begin generating revenue later this year. The Minas Gerais facility uses MOE to recover high-value materials like niobium, tantalum, and tin from mining waste. With this proven and profitable application of MOE technology, Boston Metal is unlocking new revenue streams from previously untapped resources while advancing the global circular metals economy.
“This investment is a powerful vote of confidence in the initial commercial traction and market opportunity for our critical metals business, as well as the recent technology breakthrough in our steel program,” said Tadeu Carneiro, CEO of Boston Metal. “We are grateful for the ongoing support of our world-class investors.”
