pH7 Technologies has closed an oversubscribed Series B financing round, bringing its total financing package to approximately $55 million CAD. The Vancouver-based company raised roughly USD $32 million in equity.

The proceeds will fund the commercialization and global deployment of pH7's extraction technology, beginning with copper.

The company's core technology is a closed-loop organo-electrochemical process that recovers metals from low-grade ores, tailings, and other feedstocks that have historically been uneconomic to process. The process integrates into existing on-site equipment, lowering energy consumption and wastewater generation while improving recovery rates.

pH7 currently operates a commercial facility in Vancouver extracting platinum group metals from spent catalysts and is advancing its mining-sector applications toward global deployment.

"The constraint isn't discovery, it's how we process what we've already found," said Mohammad Doostmohammadi, CEO of pH7 Technologies. "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."

The round included new backing from Asahi Kasei and the Circular Innovation Fund, alongside previously announced investors led by Fine Structure Ventures, with participation from BHP Ventures. Venture debt financing from RBCx accounts for the remainder of the total package.

Asahi Kasei cited pH7's approach to securing resilient mineral supply chains as a key draw. "We are pleased to support pH7 as it moves toward larger-scale deployment, and we look forward to sharing our longstanding expertise in electrolysis as the company enters its next phase of growth," said Takashi Morishita, Managing Director at Asahi Kasei CVC.

The Circular Innovation Fund echoed that view. "As industries accelerate decarbonization, we believe scalable technologies that can recover high-value metals from existing waste streams will play a pivotal role in securing resilient and sustainable supply chains," said Andrée-Lise Méthot, Founder and Managing Partner at Cycle Capital, which co-manages the Circular Innovation Fund alongside Paris-based Demea.
