PH7 Technologies Closes $32M Series B Round, Adds $7.5M Venture Debt

Why It Matters

Securing this funding positions pH7 to address growing critical‑metal shortages and reduce reliance on China‑dominated supply chains, while advancing climate‑friendly mining practices.

Key Takeaways

• pH7 raised $32M Series B, plus $7.5M venture debt.
• Funding targets global recycling plants for platinum group metals.
• Tech extracts copper, gold, platinum from low‑grade ores and tailings.
• Partners include BHP, Asahi Kasei, Circular Innovation Fund.
• Commercial rollout planned for mining sites 2027‑2028.

Pulse Analysis

The surge in artificial‑intelligence data centres, electric‑vehicle production and renewable‑energy infrastructure has turned critical minerals such as copper, gold and platinum‑group metals into strategic commodities. With China controlling roughly 70 % of global mining and refining capacity, governments in North America and Europe are scrambling to secure domestic sources and diversify supply chains. This geopolitical pressure, combined with rising defence budgets, is driving a wave of investment into technologies that can unlock value from low‑grade ores and mine tailings, creating a fertile environment for climate‑tech innovators.

pH7 Technologies, a Vancouver‑based cleantech firm, has raised a near‑$32 million Series B round and $7.5 million in venture debt, bringing total financing above $39 million. The company’s closed‑loop organic electrochemical process dissolves metals at lower temperatures and without harsh chemicals, promising lower energy use and reduced environmental impact compared with conventional smelting. Backed by investors such as Fine Structure Ventures, BHP Ventures, Asahi Kasei and the Circular Innovation Fund, pH7 is already processing ore from more than 20 partners at its 30,000‑square‑foot demonstration plant in Burnaby.

The new capital will fund the construction of recycling facilities for platinum‑group metals and enable pH7 to embed its extraction technology at mining sites beginning in 2027‑2028. By turning tailings and low‑grade ore into revenue streams, the solution could improve mine economics while helping companies meet ESG targets and reduce carbon footprints. If the rollout succeeds, pH7 may become a key enabler of supply‑chain resilience for the clean‑energy transition, prompting larger miners to adopt similar electrochemical platforms and potentially reshaping the global critical‑metal market.

Deal Summary

Vancouver-based pH7 Technologies announced the close of its Series B financing, raising nearly $32 million in equity and securing $7.5 million in venture debt from RBCx, bringing total financing to over $39 million. The round was led by Fine Structure Ventures with participation from BHP Ventures, Asahi Kasei, the Circular Innovation Fund and other investors.
