Renforth Resources Collaborates with Queen's University on Novel Metal Recovery and Carbon Sequestration Process

Pickering, Ontario — October 2, 2026 — Leads & Copy — Renforth Resources Inc. is collaborating with Queen's University's Robert M. Buchan Department of Mining to evaluate a novel hydrometallurgical process for recovering critical metals from its Victoria nickel sulphide polymetallic deposit, near Malartic, Québec, while simultaneously sequestering carbon dioxide.

The patent-pending process, developed by Dr. Fei Wang, Ph.D., P.Eng., and co-inventor Dr. David Dreisinger, 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 CO2 from the air as part of the process. The program includes a techno-economic analysis and life cycle assessment.

The Victoria deposit hosts an Inferred Mineral Resource of 125 Mt containing 331 Mlb nickel, 220 Mlb zinc, 55 Mlb copper, 28 Mlb cobalt and 1.53 Moz silver. Earlier mineralogical work indicated that a portion of Victoria's nickel is carried in pyrrhotite, which is typically not recovered by conventional flotation. The Queen's process is designed to leach pyrrhotite-hosted nickel and cobalt directly and is to be tested on coarse material in columns, simulating heap leaching.

The company is also evaluating conventional processing and ore sorting. Pairing metal recovery with carbon capture has the potential to lower the carbon footprint of Victoria's metals, which is an increasingly important consideration for battery and electric-vehicle supply chains.

The program is led by Dr. Fei Wang, with Dr. Qian Zhang, a specialist in techno-economic analysis and life cycle assessment, as co-supervisor. Testwork is being carried out by Postdoctoral Fellow Dr. Rida Benmansour.

The scope of the program includes characterization and bench-scale leaching of Victoria samples, column leach tests on coarse material with simultaneous carbon capture, recovery of metals from leach solutions as saleable intermediate products, and a techno-economic analysis and life cycle assessment. Testwork has commenced, and results will be reported as they become available.

Nicole Brewster, President and CEO of Renforth, stated that Dr. Wang's process addresses the challenge of nickel held in pyrrhotite while locking away carbon. She believes that working with Queen's University will provide a rigorous, independent evaluation of a processing route that could make Victoria's metals more recoverable and lower-carbon.

Dr. Fei Wang commented that Renforth's Victoria deposit ores are ideally suited to the technology, expressing confidence that the process can selectively recover critical metals directly from sulphide minerals while sequestering CO2 from the air in a single step, without requiring fine grinding, significant chemical consumption, or stringent operating conditions. She is committed to working closely with Renforth to recover critical metals and advance a carbon-neutral process.

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

The scientific and technical information in this news release related to the Victoria deposit has been reviewed and approved by Francis Newton, P.Geo. OGQ, an Independent Qualified Person. Mineral resources are not mineral reserves and do not have demonstrated economic viability; all resources at Victoria are classified as Inferred.
