Boston — Allonnia, a bio-ingenuity company developing scalable technologies to improve mineral recovery and reduce environmental impact, has raised more than $20 million in a Series A extension round. The financing was led by Viking Global Investors, Bison Ventures, General Atlantic, BHP Ventures, and Pivotal Capital Partners, bringing the company’s total funding to over $100 million.
The raise comes as global demand continues to surge for copper, nickel, lithium, and rare earth elements—materials critical to electric vehicles, grid electrification, AI data centers, and national security systems. As ore grades have declined by up to 50 percent in recent decades, miners are increasingly turning to lower-impact and more efficient technologies to extract greater value from existing operations.
Allonnia’s D-Solve platform is designed to address this challenge. Using the Allonnia Biosolution, a selective and recyclable biotechnology, D-Solve dissolves and removes problematic gangue minerals, producing cleaner and higher-value concentrates. The platform is engineered as a bolt-on solution that fits within existing flowsheets, helping miners improve recovery, increase throughput, and reduce both tailings and chemical consumption.
The new funding will support the commercial rollout of D-Solve, including Allonnia’s first mine-site pilot. This follows promising scale-up results from a five-day continuous demonstration at SGS Lakefield in Ontario, where the technology achieved a 40 percent reduction in magnesium impurities and an 18 percent increase in nickel grade. In August 2025, the company announced that its first mobile D-Solve unit will be deployed at Eagle Mine, the only active nickel mine in North America, with operations set to begin in December.
“The world cannot meet its critical mineral needs with traditional approaches alone,” said Nicole Richards, CEO of Allonnia. “D-Solve provides a new path forward by improving concentrate quality, increasing production and reducing the burden of inputs and waste. This investment accelerates our ability to transition from successful demonstrations to real world impact across active mine sites.”
Investors noted the importance of Allonnia’s technology in strengthening mineral supply chains needed for the energy transition.
“Allonnia is developing differentiated biotechnologies to address critical challenges in mineral supply chains. We are pleased to deepen our partnership with Allonnia as the Company continues to translate its strong technical foundation into practical, scalable, and innovative solutions,” said Brett Zbar, Managing Director and Global Head of Life Sciences at General Atlantic.
“At Bison, we invest in companies that pair scientific ambition with a disciplined path to market. Allonnia exemplifies this approach through the development of the type of breakthrough technologies needed to strengthen critical mineral supply chains and reduce environmental impact,” said Tom Biegala, Founding Partner at Bison Ventures. “The team has a history of demonstrated speed, discipline, and a clear line of sight to commercial adoption building on their success with commercialization of PFAS separation and concentration solution.”
Allonnia continues to expand its selective separation portfolio in two core markets: metals and mining—covering impurity removal, concentrate upgrading, and rare earth recovery—and emerging contaminants, including solutions such as SAFF, its PFAS treatment platform.
