pH7 Technologies Secures $25.6 Million Series B to Scale Critical Metals Extraction Technology
pH7 Technologies Inc., a leading innovator in commercially scalable critical metal extraction solutions, announced the initial closing of USD $25.6 million in its Series B financing round. The round was led by Fine Structure Ventures, with BHP Ventures joining as a key strategic investor. Additional participants include Energy & Environment Investment (EEI), Siteground, Gaingels Fund, and Calm Venture, alongside continued support from existing investors such as TDK Ventures, Pangaea Ventures, Rhapsody Venture Partners, and BASF Venture Capital.
The funding will be used to accelerate the scaling and commercialization of pH7’s proprietary extraction technology for the mining sector, starting with copper, as global demand for critical minerals continues to outpace supply.
Advancing Critical Metals Extraction
pH7 Technologies is pioneering an approach to extract critical metals economically from lower-grade ores and other feedstocks traditionally considered uneconomic to process. By doing so, the company is unlocking new domestic sources of copper, nickel, and Platinum Group Metals (PGMs).
The proceeds from this Series B round will support commercial deployments and on-site demonstrations of pH7’s technology at mining operations worldwide. This effort positions pH7 as a key player in addressing the global supply gap for essential metals required for modern infrastructure, electronics, and the energy transition.
CEO Statement: Transforming Mining Economics
“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.
He added, “We are accelerating the transition from pilot projects to commercial deployments, enabling operators to produce copper and other critical minerals directly on-site. At a time of global scarcity, geopolitical competition for resources, and growing focus on resilient supply chains, our technology provides a pathway for nations to secure domestic sources of metals that are foundational to infrastructure and the energy transition.”
Innovative Technology: Closed-Loop Organo-Electrochemical Process
pH7’s proprietary closed-loop organo-electrochemical extraction process is designed to replace traditional, high-waste mining methods with a scalable, economically viable system. Unlike conventional processes, this method reduces energy consumption, lowers wastewater production, and minimizes environmental impact.
The system is engineered to integrate seamlessly into existing on-site equipment and workflows, reducing operational complexity while enhancing resource recovery. This combination of economic efficiency and sustainability makes pH7’s technology particularly attractive to mining operators seeking both profitability and environmental compliance.
Strategic Investor Support
The Series B round attracted both venture capital and strategic corporate investors, reflecting strong confidence in pH7’s technology and market potential.
Shyam Kamadolli, Managing Director at Fine Structure Ventures, commented:
“We’re excited to back pH7 as they unlock new sources 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 essential metals.”
Laurel Buckner, VP of Ventures at BHP, added:
“The electrochemical process developed by pH7 unlocks significant opportunities for extracting critical minerals from lower-grade ores. At BHP Ventures, we see this kind of leap in extraction technology as transformative for securing the critical minerals the world urgently needs.”
Commercial Progress and Pilot Success
pH7 has already demonstrated the commercial potential of its technology at its Vancouver facility, where it is successfully extracting Platinum Group Metals from spent catalysts. This operational success validates the underlying chemistry and provides a strong foundation for expanding into other metals and geographies.
In addition to its PGM extraction operations, pH7 has advanced its mining-sector technology to pilot scale, positioning the company for its next phase of growth. The upcoming focus will be on full-scale commercial deployments in copper and other critical mineral operations, supported by the capital raised in this Series B round.
Meeting Global Demand for Critical Minerals
The timing of this financing is particularly significant. Demand for critical minerals such as copper, nickel, and PGMs is surging due to renewable energy deployment, electric vehicle adoption, and infrastructure modernization. Traditional mining processes often struggle to meet this demand economically, particularly when dealing with lower-grade ores.
pH7’s technology addresses these challenges by enabling operators to process ores that were previously uneconomic, unlocking new domestic sources and enhancing supply chain resilience. This is especially important in the context of geopolitical resource competition, where secure local sources of critical metals are becoming a strategic priority for nations worldwide.
Environmental and Operational Advantages
Beyond its economic benefits, pH7’s process is designed with sustainability in mind. The closed-loop system significantly reduces waste generation and energy consumption compared to conventional extraction methods. By integrating into existing mining infrastructure, the technology minimizes disruption while improving overall project economics.
This approach positions pH7 as a leader in responsible mining innovation, providing both economic and environmental incentives for adoption across the global mining sector.
With the successful closing of the Series B funding, pH7 Technologies is poised to accelerate its growth trajectory. The capital will support:
- Commercial deployments at active mining sites
- On-site demonstrations to validate performance in real-world conditions
- Expansion into additional metals such as nickel and PGMs
- Further research and development to refine and scale the technology
The company’s vision is clear: to redefine how critical metals are sourced, providing miners with a tool to extract value from resources previously considered uneconomical, while supporting the global transition to sustainable energy and resilient supply chains.
