This will be followed by the Phase 4 commercial production demonstration campaign, with a processing capacity of approximately 300 tonnes per annum. These campaigns represent a critical step in advancing the NVRO Process™ from technical validation toward commercial deployment by providing scale-up data and operational insights. Commercial Validation and Product Definition The Greens Creek feedstock will undergo sampling, analytical assessment, and preparatory work ahead of the pilot and demonstration campaigns. The Phase 3 and Phase 4 campaigns are expected to be completed by late August 2026, subject to third-party laboratory turnaround times. The program is designed to confirm process performance at increasing scale, produce material for assessment of product quality and saleability, and define commercial pathways for primary product streams and potential by-products.
