RENFORTH RESOURCES LAUNCHES RESEARCH COLLABORATION WITH QUEEN'S UNIVERSITY ON LOW-CARBON RECOVERY OF CRITICAL METALS FROM THE VICTORIA DEPOSIT

Renforth Resources Inc. has arranged a research collaboration with Queen's University's Robert M. Buchan Department of Mining to evaluate a novel hydrometallurgical process for recovering critical metals from its wholly owned Victoria nickel sulphide polymetallic deposit, near Malartic, Quebec, while simultaneously sequestering carbon dioxide.

Highlights:

• Bench-scale and column-leach testing of Victoria material using a patent-pending process developed by Dr. Fei Wang, PhD, PEng, and co-inventor Dr. David Dreisinger;
• The process is designed to selectively recover nickel and cobalt from pentlandite, violarite and pyrrhotite, and copper and zinc from chalcopyrite and sphalerite, directly from low-grade sulphide material;
• Magnesium- and iron-bearing minerals in Victoria's ultramafic host rock are converted to stable carbonates, capturing carbon dioxide from air as part of the process;
• The program includes a techno-economic analysis and life cycle assessment.

Why this matters for Renforth's Victoria deposit

The Victoria deposit hosts an inferred mineral resource of 125 million tonnes containing 331 million pounds nickel, 220 million pounds zinc, 55 million pounds copper, 28 million pounds cobalt and 1.53 million ounces silver (P&E Mining Consultants Inc., effective Sept. 26, 2025). Earlier mineralogical work showed that a portion of Victoria's nickel is carried in pyrrhotite rather than in discrete nickel sulphides. Nickel in this form is typically not recovered by conventional flotation. The Queen's process is designed to leach pyrrhotite-hosted nickel and cobalt directly and to be tested on coarse material in columns, the laboratory analogue of heap leaching. That approach could complement conventional processing and ore sorting, which the company is also evaluating.

The same ultramafic rocks that host Victoria's nickel are well suited to mineral carbonation, in which carbon dioxide reacts with magnesium- and iron-bearing minerals to form stable, permanent carbonates. Pairing metal recovery with carbon capture has the potential to lower the carbon footprint of Victoria's metals, an increasingly important consideration for battery and electric-vehicle supply chains.

The research team

The program is led by Dr. Fei Wang, PhD, PEng, of the Robert M. Buchan Department of Mining at Queens University, co-inventor of the process, with Dr. Qian Zhang, a specialist in techno-economic analysis and life-cycle assessment, as co-supervisor. The test work is being carried out by postdoctoral fellow Dr. Rida Benmansour, whose prior research at Universite Laval focused on coupling carbon dioxide mineralization with the selective recovery of nickel and cobalt from ultramafic materials.

Program scope:

• Characterization and bench-scale leaching of Victoria samples under neutral and weakly alkaline conditions;
• Column-leach tests on coarse Victoria material to simulate heap leaching with simultaneous carbon capture;
• Recovery of nickel, cobalt, copper and zinc from leach solutions as saleable intermediate products;
• Techno-economic analysis and life cycle assessment of the process.

Test work has commence; results will be reported as they become available.

Nicole Brewster, president and chief executive officer of Renforth, commented: "Victoria is a large, multimetal deposit, and understanding how best to recover each of those metals is the key question for its future. Dr. Wang's process goes straight at one of the more challenging parts of that question, the nickel held in pyrrhotite, and does it while locking away carbon. Working with Queen's gives us a rigorous, independent look at a processing route that could make Victoria's metals both more recoverable and lower-carbon."

Dr. Wang commented: "Renforth's Victoria deposit ores are ideally suited to the technology we have developed. I am confident that our process can help Renforth selectively recover the critical metals directly from the sulphide minerals in the Victoria ores while simultaneously sequestering CO2 from air in a single step. No fine grinding, chemical consumption and stringent operation conditions would be needed. We are committed to working closely with Renforth to successfully recover the critical metals from the Victoria deposit while advancing a carbon-neutral process."

Intellectual property

The process is the subject of patent applications by Dr. Wang and Dr. Dreisinger, including PCT/CA2024/051679. Renforth and Queen's University are finalizing a research agreement that addresses intellectual property arising from the collaboration.
