RZOLV Technologies (TSXV: RZL, OTCQB: RZOLF) signed a non-binding LOI dated July 15, 2026 with Argentina-based Alkemio Bioscience to pursue a strategic collaboration integrating RZOLV's hydrometallurgical platform with Alkemio's molecular-recognition separation and refining technology for rare earth and critical minerals recovery.
The companies aim to develop, validate and potentially commercialize a modular, source-adjacent processing pathway spanning metal unlocking, selective recovery, separation and product upgrading from primary and secondary feedstocks. Alkemio reports lab recovery efficiencies above 87% and development targets including facilities up to 200x smaller, potential capital reductions of up to 80% and potential profit improvements of up to 50%, all subject to further testing and independent validation. Future joint development, pilot projects, SPVs, joint ventures and licensing would require definitive agreements.
RZOLV Technologies (OTCQB:RZOLF) has appointed veteran mining executive John C. McConnell, former President and CEO of Victoria Gold, to its Board of Directors, effective July 14, 2026. The company states that his 40 years of experience will enhance governance, technical oversight and mining-industry expertise as it advances independent validation, scale-up and potential commercialization of its non-cyanide hydrometallurgical platform.
RZOLV Technologies (OTCQB:RZOLF) announced the passing of co-founder, honorary chairman and Canadian Mining Hall of Fame member Chester Ferguson Millar, who died peacefully on June 23, 2026, aged 98.
The release highlights his pioneering role in heap leach gold mining, discovery of the Afton Mine, founding of Alamos Gold and Glamis Gold, long industry mentorship, family, and a request to honor him by leaving a flower at Vancouver’s Nine O'clock Gun.
RZOLV Technologies (OTCQB:RZOLF) reported positive preliminary bottle-roll test results for its proprietary RZOLV platform on two low-grade copper-gold composites.
Gold recoveries were 82.3%–94.8% and copper extraction 71%–80%, with lower reported RZOLV additions after copper pre-treatment. Results are sample-specific, laboratory-scale, and not indicative of commercial performance; further optimization, repeatability, scale-up, and economic studies are planned.
RZOLV Technologies (OTCQB:RZOLF) announced completion of Innovation Mining’s first NRC IRAP-supported R&D project for its proprietary non-cyanide RZOLV™ gold extraction technology. Work covered bench-scale electrochemical regeneration, reagent management, and process control, generating internal data for future closed-loop tests, pilot-scale work, and process optimization.
The project did not include commercial-scale demonstration. RZOLV added two full-time laboratory employees, expanding in-house technical capacity to support ongoing validation, scale-up, and strategic commercial engagement for the RZOLV technology platform.
RZOLV Technologies (OTCQB:RZOLF) reported preliminary technical work suggesting its proprietary non-cyanide RZOLV™ hydrometallurgical platform may mobilize rare earth elements (REEs) from selected feedstocks, expanding beyond gold recovery.
Testing on a mine sample showed apparent response for multiple light, heavy and magnet REEs, including neodymium, praseodymium, dysprosium and terbium. RZOLV outlined a modular process architecture combining controlled aqueous leaching with molecular adsorption and chromatography, and a stage-gated validation program. The company emphasized results are early, based on internal tests, and do not yet represent confirmed solution or commercial recoveries.
RZOLV Technologies (OTCQB:RZOLF) presented its proprietary, water-based, non-cyanide RZOLV™ gold recovery platform at Mining Innovation on the Hill in Ottawa on June 9, 2026.
The company highlighted MICA-supported scale-up work, field-relevant testing, and a disciplined commercialization path targeting safer, lower-toxicity mineral processing options.
RZOLV Technologies (OTCQB: RZOLF) reports ~97.0% gold recovery on a complex copper-gold ore using its formula without pretreatment. The tested material assayed ~9.6 g/t Au and 2.12% Cu and was processed in a 150 g bottle-roll test at 20% pulp density over 168 hours.
RZOLV says the result suggests potential flowsheet simplification versus cyanide (possible avoidance of a SART circuit), lower capital intensity and reduced reagent penalty, while noting further metallurgical work and scale-up are planned.
RZOLV (OTCQB: RZOLF) announced a strategic partnership with EMEW Clean Technologies to develop integrated feed-to-metal solutions for precious and critical metals recovery. Based on a March 30, 2026 agreement, the collaboration pairs RZOLV's patent-pending non‑cyanide, water‑based extraction with EMEW's electrowinning and global commercial footprint.
Initial efforts will evaluate precious‑metal concentrates, doré refining, tailings reprocessing and selected secondary feedstocks, leveraging EMEW's presence in Australia, Canada, India, Ireland, Dubai and Mexico and its >30 years of metal‑recovery experience.
RZOLV Technologies (OTCQB: RZOLF) reported metallurgical bottle roll test results showing approximately 97.0% gold recovery on a complex copper-gold ore without pretreatment. The tested head grade was ~9.6 g/t Au with 2.12% Cu, run at 20% pulp density over 168 hours.
RZOLV says this result could simplify flowsheets versus cyanide-based routes by potentially avoiding SART circuits, lowering capital intensity and reducing reagent penalties, subject to further testing, verification and scale-up.
