NVRO Metals ran a 202-hour continuous production campaign using material from Hecla Mining's Greens Creek operation in Alaska, generating engineering and operating data that management says supports moving toward a full-scale plant.
The campaign, completed at the company's μNVRO Production Demonstration Plant, processed customer feedstock under conditions matching the company's IDEAS digital simulation model. Sulfide oxidation reached approximately 97%, indicating effective breakdown of refractory minerals and release of the metals they contain, the company said in a release.
Management called the result a milestone in commercializing the NVRO Process, a clean-technology method for recovering precious, base, and critical metals from complex sulfidic tailings and ores. The demonstration cut technical risk for future commercial applications, the company said, and strengthens its ability to advance discussions with mining companies seeking alternative processing routes.
The campaign was designed to support evaluation of a 35,000-tonne commercial processing trial under a memorandum of understanding with Hecla, announced July 8, 2026. The two companies are assessing the NVRO Process as a potential commercial solution for Greens Creek tailings.
