EnviroGold Advances Greens Creek Project Toward Commercial Validation with Arrival of Feedstock for Pilot and Demonstration Campaigns

EnviroGold announced the arrival (April 21, 2026) of Greens Creek tailings in Fremantle to support Phase 3 (micro NVRO) and Phase 4 (commercial demonstration) validation of its NVRO Process™. The pilot will operate at ~50 kg/day and the demonstration at ~300 tonnes per annum, with campaigns expected to complete by late August 2026. Successful runs aim to deliver technical and commercial data to advance the technology to TRL 8 (commercial validation) and provide a pathway to TRL 9 (full industrial-scale production), product saleability and potential revenue-generating deployments. Market impact is indirect: progress may de-risk a low‑impact route to recover gold, silver and other critical metals from tailings, supporting EnviroGold’s commercial prospects and longer-term supply/delivery options for precious metals, with modest implications for companies exposed to secondary metal recovery and ESG-focused metal supply chains.
