pH7 Technologies Secures $25.6 Million Series B To Advance Commercial Critical Metals Extraction

By Amit Chowdhry • Dec 5, 2025

pH7 Technologies has raised an initial $25.6 million in Series B financing to scale its next-generation critical-minerals extraction platform, positioning the Vancouver-based company for broader commercial deployments across the global mining sector. The round was led by Fine Structure Ventures, with BHP Ventures joining as a strategic investor.

Additional participation came from Energy & Environment Investment, Siteground, Gaingels Fund, Calm Venture, and existing backers, including TDK Ventures, Pangaea Ventures, Rhapsody Venture Partners, and BASF Venture Capital. The company expects the total Series B raise to exceed $30 million upon subsequent closings.

Funding will support the expansion and commercialization of pH7’s closed-loop organo-electrochemical extraction method, beginning with copper, as demand for critical minerals continues to outpace supply. The system enables mining operators to economically extract metals from lower-grade ores and complex feedstocks that have traditionally been uneconomic to process. The company plans to use the new capital to accelerate commercial deployments and begin on-site demonstrations at mining operations worldwide.

pH7’s technology replaces conventional high-waste extraction methods with a process designed to improve metal recovery, reduce energy consumption, and minimize wastewater generation, all while integrating into familiar mine-site equipment and flowsheets. The company already operates a commercial facility in Vancouver that extracts platinum group metals from spent catalysts and has advanced its mining-sector platform to pilot scale as it prepares for broader market adoption.

Fine Structure Ventures and BHP Ventures highlighted the commercial relevance and global impact potential of pH7’s extraction approach, which aims to expand domestic access to copper, nickel, and PGMs at a time of mineral scarcity, geopolitical competition, and increased pressure on supply chains.

KEY QUOTES

“This Series B funding is a major validation of our technology for the economic value it brings to miners and metal producers.”

“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.”

Mohammad Doostmohammadi, CEO of pH7 Technologies

“We’re excited to back pH7 as they unlock a new source of critical minerals by making extraction from previously uneconomic ores commercially viable. This breakthrough offers a scalable, economically sound, and cleaner approach to meeting the world’s growing demand for critical minerals.”

Shyam Kamadolli, Managing Director at Fine Structure Ventures

“The electrochemical process developed by pH7 unlocks a significant opportunity through enabling the extraction of critical minerals from lower-grade ores. At BHP Ventures, we believe this kind of leap in extraction technology could transform our ability to source the critical minerals the world urgently needs.”

Laurel Buckner, VP of Ventures at BHP
