pH7 Technologies raises US$25.6 million Series B to scale critical metals extraction technology

The round was led by Fine Structure Ventures, with BHP Ventures joining as a key strategic investor, alongside Energy & Environment Investment (EEI), Siteground, Gaingels Fund, and Calm Venture, with continued participation from existing investors including TDK Ventures, Pangaea Ventures, Rhapsody Venture Partners, and BASF Venture Capital.

Proceeds from the financing will advance the scaling and commercialisation of pH7’s extraction technology for the mining sector, beginning with copper, as global demand for critical minerals continues to outpace supply. pH7’s extraction technology enables operators to economically recover metals from lower-grade ores, and other feedstocks that have historically been uneconomic to process – unlocking new domestic sources of copper, nickel, and PGMs. Proceeds from the round will support commercial deployments and on-site demonstrations at mining operations globally.

“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.”

pH7’s proprietary extraction method, a closed-loop organo-electrochemical process, replaces traditional high-waste extraction methods with a scalable system designed to improve project economics while minimising environmental impact. The technology integrates into familiar on-site equipment and flowsheets, reducing operational complexity while improving resource recovery. In addition to strong economic advantages, the process reduces energy consumption, and wastewater generation compared to industry norms.

“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.”

“The electrochemical process developed by pH7 unlocks a significant opportunity through extraction of critical minerals from low-grade ores and tailings,” said Laurel Buckner, VP of Ventures at BHP. “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.”

The company has already commercialised its technology at the Vancouver facility for extraction of Platinum Group Metals (PGMs) from spent catalysts. pH7 has also advanced its mining-sector technology to pilot scale, positioning the company for its next phase of commercial growth.
