Vancouver cleantech standout pH7 Technologies has secured USD $25.6 million in the initial close of its Series B round, positioning the company to accelerate commercial deployments of its breakthrough mineral extraction technology at a time when global demand for copper and other critical minerals is surging.
The round was led by Fine Structure Ventures, with BHP Ventures joining as a key strategic investor. Additional investors include Energy & Environment Investment (EEI), Siteground, Gaingels Fund, and Calm Venture, with continued participation from existing backers such as TDK Ventures, Pangaea Ventures, Rhapsody Venture Partners, and BASF Venture Capital.
The funding arrives amid a tightening global race for copper, a metal expected to face severe supply shortages as electrification, AI infrastructure, renewable power build-out, and grid expansion accelerate. With miners increasingly forced to rely on lower-grade deposits—and traditional methods proving too costly or too polluting to process them—pH7’s technology is emerging at an important moment.

pH7’s closed-loop organo-electrochemical extraction process enables operators to economically recover metals from ores and feedstocks previously considered uneconomic, unlocking new domestic sources of copper, nickel, and PGMs. The system integrates into familiar on-site equipment and flowsheets, reducing operational complexity while lowering energy use, waste, and water consumption.
The Series B financing will support commercial deployments and on-site demonstrations at mining operations worldwide.
“This Series B funding is a major validation of our technology for the economic value it brings to miners and metal producers,” said Mohammad Doostmohammadi, CEO of pH7 Technologies. “We are accelerating the transition from pilot to commercial deployments, enabling operators to produce copper and other critical minerals directly on-site. At a time of global scarcity, geopolitical resource competition, and growing emphasis on strengthening sovereign supply chains, our technology provides a new pathway for nations to secure resilient, domestic sources of the metals that underpin modern infrastructure and the energy transition.”
Investors say pH7 is opening a door the mining sector has been waiting for.
“We’re excited to back pH7 as they unlock a new source of critical minerals by making extraction from previously uneconomic ores commercially viable,” said Shyam Kamadolli, Managing Director at Fine Structure Ventures. “This breakthrough offers a scalable, economically sound, and cleaner approach to meeting the world’s growing demand for critical minerals.”
Laurel Buckner, VP of Ventures at BHP, echoed the transformative potential. “The electrochemical process developed by pH7 unlocks a significant opportunity through extraction of critical minerals from low-grade ores and tailings,” she said. “This kind of leap in extraction technology could transform how critical minerals are sourced and help provide more of the critical mineral the world urgently needs.”
While pH7 is best known for its mining-sector breakthrough, the company has already commercialized a version of its technology at its Vancouver facility, where it extracts Platinum Group Metals from spent catalysts. Its mining-focused systems have advanced to pilot scale, setting the stage for full commercial expansion.
With fresh capital, strategic partnerships, and global miners paying close attention, pH7 is positioning itself as one of B.C.’s next major cleantech scaleups—arriving just as the world’s appetite for critical minerals reaches historic highs.
