Renforth and Queen's University test nickel recovery with carbon capture at Victoria deposit

Renforth Resources is partnering with Queen's University to test a hydrometallurgical process that recovers nickel and cobalt from pyrrhotite at its Victoria deposit in Quebec while capturing CO2. The process uses column leach tests on coarse material to simulate heap leaching, with mineral carbonation converting CO2 into stable carbonates. Victoria hosts 331 million pounds of nickel in an Inferred Mineral Resource, along with cobalt, copper, zinc, and silver. The work includes bench-scale leaching, recovery of nickel, cobalt, copper, and zinc as saleable intermediates, plus techno-economic analysis and life cycle assessment. The goal is to lower the carbon footprint of battery metals, which is becoming a selling point for EV supply chains. Renforth and Queen's are finalizing an IP agreement. This is early-stage testwork, not production. But if the process works at scale, it could make the Victoria deposit more attractive and give the company a carbon capture angle that most nickel projects cannot offer.

Interesting tie between metal recovery and carbon capture. Victoria is a big resource, but this is bench scale and column tests, so still early. The key question is whether the leach process works on coarse material at a cost that makes sense. If it does, it could lower the carbon footprint of nickel for batteries.

Heap leaching nickel from pyrrhotite is not the usual route. I'd want to see recovery rates and reagent consumption before getting excited. Mineral carbonation on ultramafics works, but the rate and scale matter. Hope the techno-economic analysis is public.

The carbon capture part only matters if it is measured and verified. Mineral carbonation can be permanent, but the emissions accounting for the process itself, including mining, crushing, and leaching, has to be included. If they can show net-negative nickel, that changes the offtake story for EV supply chains.

Good to see a junior miner working with a university on process development. The IP agreement is worth watching. If the process works, it could be licensed beyond Victoria. But the resource is Inferred, so the economics are still a ways off.
