pH7 Technologies announced the oversubscribed final close of its Series B financing round, raising approximately $32 million in equity and securing additional venture debt, bringing its total financing package to about C$55 million.
The round drew support from a global group of industrial and financial investors, including Asahi Kasei and the Circular Innovation Fund, alongside previously announced backers led by Fine Structure Ventures, with participation from BHP Ventures and existing investors.
The new capital will be used to accelerate commercialization and global deployment of pH7’s proprietary extraction technology, which enables mining operators to recover critical minerals from low-grade ores, tailings, and other previously uneconomic sources. The company is initially focused on copper, with broader applications across nickel, gold, and platinum group metals.
The financing comes as global demand for critical minerals continues to surge amid supply constraints and increasing geopolitical competition. pH7’s technology aims to address these challenges by improving recovery rates while reducing environmental impact through a closed-loop organo-electrochemical process that lowers energy consumption and wastewater generation.
The company currently operates a commercial facility in Vancouver focused on extracting platinum group metals from spent catalysts and is advancing its mining-sector applications toward broader global deployment.
KEY QUOTES:
“The constraint isn’t discovery, it’s how we process what we’ve already found. This oversubscribed financing validates that unlocking value from existing resources is now an economic and strategic priority. We are accelerating from pilot to commercial deployment globally, enabling producers to recover critical minerals from materials that were previously uneconomic—while enabling regionalized, on-site metal processing closer to the source of production.”

“pH7 is applying electrochemistry and process engineering in a compelling way to help secure a more resilient supply of critical minerals by recovering value from resources that have traditionally been uneconomic to process.”
Takashi Morishita, Managing Director, Asahi Kasei CVC
“The Circular Innovation Fund is proud to support pH7 Technologies, a company addressing a critical challenge at the heart of the energy transition: the growing gap between surging demand for critical metals and increasingly constrained global supply.”
