-- EnviroGold Global (NVRO.V) announced Wednesday that the shipment of Hecla Mining Company's Greens Creek tailings arrived in Fremantle, Western Australia, on April 21.
The company said tailings will be used for the next phase of process validation and commercial advancement of its proprietary NVRO Process. Validation of the NVRO Process will advance to the Phase 3 micro NVRO pilot plant campaign, operating at about 50 kg per day.
It said Phase 3 will be followed by the Phase 4 commercial production demonstration campaign, with a processing capacity of about 300 tonnes per annum. The Phase 3 and Phase 4 campaigns are expected to be completed by late August 2026, subject to third-party laboratory turnaround times.
"The micro NVRO and commercial scale demonstration campaigns will generate the technical and commercial data required to advance process maturity and support progression to TRL 8, including confirmation of product saleability and commercial pathways," said EnviroGold Chief Executive Grant Freeman. "This program defines a clear pathway to TRL 9 and full commercial deployment, supporting EnviroGold's strategy to deliver an industrial-scale process and advance projects to revenue-generating operations."
Shares of the company closed unchanged at $0.175 on Tuesday on the TSX Venture Exchange.
