pH7 Technologies has closed the first tranche of its USD $25.6 million Series B financing, a round expected to surpass $30 million in subsequent closings, as the Canadian cleantech firm accelerates commercialization of its next-generation critical-minerals extraction technology.
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, Calm Venture, and returning backers TDK Ventures, Pangaea Ventures, Rhapsody Venture Partners, and BASF Venture Capital.
“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.
Scaling Next-Generation Extraction Technology
Proceeds will support global deployment of pH7 Technologies’ proprietary closed-loop organo-electrochemical process—designed to recover copper, nickel, and platinum group metals (PGMs) from ores and feedstocks historically considered too low-grade or uneconomic to process. The company aims to accelerate on-site demonstrations and support mining operators seeking domestic and resilient metal supply as geopolitical pressures intensify.
“We are accelerating the transition from pilot to commercial deployments… enabling operators to produce copper and other critical minerals directly on-site,” Doostmohammadi said. He emphasized that nations are now prioritizing secure supply chains amid scarcity, infrastructure needs, and the global energy transition.
Investor Confidence in a Cleaner, Scalable Alternative
“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. He described the company’s method as a “scalable, economically sound, and cleaner approach” at a time when global mineral demand is accelerating.
“The electrochemical process developed by pH7 unlocks a significant opportunity,” added Laurel Buckner, VP of Ventures at BHP Ventures. “This kind of leap in extraction technology could transform our ability to source the critical minerals the world urgently needs.”
The firm already operates a commercial facility in Vancouver for extracting PGMs from spent catalysts and has advanced its mining-sector platform to pilot scale, positioning pH7 Technologies for broader commercial expansion.
Editorial Perspective: Why pH7 Technologies Is Positioned for Outsized Impact
The momentum behind pH7 Technologies is not merely financial—it reflects a deeper structural shift in how the world will secure the metals that power electrification, manufacturing, AI infrastructure, renewable energy, and national defense. Traditional extraction methods are costly, environmentally burdensome, and increasingly constrained by declining ore grades. pH7’s low-waste, closed-loop electrochemical process arrives at precisely the moment when mining companies need alternatives that are both scalable and sustainable.
What stands out is the company’s practical integration strategy: rather than requiring operators to overhaul existing infrastructure, pH7 Technologies designs its system to fit within familiar on-site equipment and flowsheets. This reduces operational friction—one of the mining sector’s most persistent barriers to adopting new technologies.
The investor lineup further underscores the company’s potential. With BHP Ventures, one of the world’s most influential mining investors, and Fine Structure Ventures—known for backing deep-tech companies—the validation goes beyond capital. It signals confidence that pH7’s process can meaningfully reshape the economics of domestic mineral recovery, helping nations strengthen sovereignty over critical supply chains.
If the company delivers on its commercial rollout as planned, it may become one of the most consequential extraction-tech innovators of the decade—bridging economic viability and environmental responsibility in a sector that needs both.
