Under the MOU, the parties will endeavor to establish the technical and commercial framework for a proposed industrial-scale processing campaign of approximately 35,000-tonnes Hecla tailings for feedstock to be processed at the NVRO Metals Hub (“The Metals Hub”) using the NVRO Process™. The Company announced the proposed acquisition of the assets comprising the Metals Hub on 10 June 2026, and completion of that acquisition remains subject to conditions but is expected to close in August 2026. The MOU represents an important milestone in the commercialization of the NVRO Process™ as an industrial scale mineral processing technology and establishes a potential pathway toward industrial-scale demonstration of the technology using customer feedstock. The successful completion of the campaign would represent a further step toward Technology Readiness Level 9 (TRL9) for the NVRO Process. Management believes the MOU also provides an early opportunity to demonstrate the role the NVRO Metals Hub is intended to play within the Company’s broader critical minerals supply chain strategy. The NVRO Metals Hub is being developed as a centralized critical minerals processing platform capable of supporting industrial-scale third-party processing opportunities using the NVRO Process™. Conditions and Next Steps The MOU is non-binding and remains conditional upon successful completion, to Hecla’s satisfaction, of the Company’s current production demonstration campaign on the previously announced 20-tonnes of Hecla feedstock at the Company’s Perth, Western Australia facility. A further condition is the completion of the Company’s acquisition and commissioning of the Company’s <a href="https://nvrometals.com/nvro-metals-establishes-the-nvro-metals-hub-creating-a-pathway-to-critical-minerals-production-and-accelerating-industrial-deployment-of-the-nvro-process/" rel="nofollow" target="_blank" title="previously announced NVRO Metals Hub">previously announced NVRO Metals Hub</a>. These conditions are required to be satisfied on or before December 30, 2026, unless otherwise agreed between the parties. “We are honoured to continue working with Hecla Greens Creek Mining. This MOU establishes a pathway toward industrial-scale deployment of the NVRO Process™ using customer feedstock and represents an important step in the commercialization of our technology and the important role that the NVRO Metals Hub can play as a centralized critical minerals processing platform,” said Grant Freeman, CEO of NVRO Metals Limited.
