RZOLV Technologies Inc. (TSXV: RZL) (OTCQB: RZOLF) (FSE: S711) announced bench-scale testing results showing 99.9% silver extraction from solar-panel concentrate material, calculated from independent ALS assays. The Vancouver-based clean technology company also reported that subsequent electrowinning testwork recovered 99.85% of dissolved silver from solution after five hours. The results advance RZOLV's non-cyanide silver recovery platform targeting end-of-life solar panels, a market investors may be watching given a forecast sixth consecutive annual deficit in global silver supply.

Key Points

  • RZOLV Technologies Inc. (TSXV: RZL, OTCQB: RZOLF, FSE: S711) is a Canadian clean technology company commercialising non-cyanide metal recovery solutions.
  • Bench-scale testing achieved 99.9% silver extraction to solution from solar-panel concentrate, confirmed by independent ALS assays of feed and final washed residue.
  • Electrowinning reduced dissolved silver concentration by 40.4% within 10 minutes and 99.85% after five hours; reagent consumption was calculated at approximately 10%, with roughly 90% expected available for reuse.
  • Final recovery to a refined silver product remains subject to product weighing, assaying, mass-balance reconciliation, and accounting for refining losses.

RZOLV's™ Non-Cyanide Leaching Process Delivers Near-Complete Silver Dissolution

The company's proprietary RZOLV™ platform achieved silver extraction to solution of 99.99% after 24 hours, calculated from ALS assays of the feed and final washed residue together with recorded dry masses. Reagent consumption was measured at approximately 10%, with roughly 90% expected to remain available for reuse in the next leaching cycle. The release states this supports development of a closed-circuit recovery platform designed to lower reagent costs and reduce waste, positioning the technology as a potentially lower-cost and more environmentally considerate alternative to conventional cyanide-based processing.

Electrowinning Results Show Rapid Silver Recovery from Pregnant Leach Solution

Following the leaching stage, RZOLV conducted electrowinning testwork on the pregnant leach solution. Dissolved silver concentration decreased by 40.4% within the first 10 minutes and by 99.85% after five hours relative to the starting concentration. The company notes that electrowinning uses an electric current to deposit dissolved silver as a solid for collection. Together, the two-stage results address both core value-recovery steps: dissolving silver from solids into solution and then removing it from solution. However, the company cautions that final recovery to a refined product remains subject to further confirmation through weighing, assaying, and mass-balance reconciliation.

Solar-Panel Silver Content and Market Context Behind RZOLV's Recycling Strategy

Crystalline-silicon solar panels contain silver in solar-cell electrical contacts. Mechanical recycling can isolate a silver-bearing cell-dust fraction at a yield of approximately 40 kilograms per tonne of panels, representing roughly 4% of original panel mass. The disclosure suggests this concentration allows hydrometallurgical treatment to focus on a much smaller processing stream. The Silver Institute's World Silver Survey 2026 forecasts a sixth consecutive annual deficit in the global silver market in 2026, a macro backdrop that may increase investor attention on secondary silver recovery initiatives such as RZOLV's solar recycling platform.

Commercial Discussions Underway as RZOLV Builds Circular Supply Chain Partnerships

The release states RZOLV is currently in discussions with several manufacturers, recyclers, technology providers, and refiners with the goal of building a global circular supply chain that recovers silver from end-of-life solar panels and returns it to manufacturing. The company frames recovered solar silver as a potential revenue stream for recyclers and an additional source of secondary silver supply. The immediate share price impact was not clear from available public information. Preliminary laboratory results may not be reproduced at larger scale, and actual outcomes may differ materially from current expectations.
