EnviroGold Global Announces Positive ANDRITZ Case Study Confirming NVRO Process(TM) Commercial Readiness and Global Scalability

Executive Summary

• EnviroGold Global announced an independent case study by ANDRITZ that validates the performance and scalability of its proprietary NVRO Process™ for metal recovery from mine waste.
• The study reports dramatic improvements—including a 286% increase in gold concentrate grade, 450% increase in silver grade, 82% gold recovery, and 96.3% oxidation efficiency—supporting the company’s commercialization strategy and licensing model.
• Validation strengthens EnviroGold’s engagements worldwide and underpins anticipated royalty and net‑smelter‑return revenue streams from future licensed deployments.

Key Details

• Study Sponsor: ANDRITZ, using its IDEAS™ digital‑modelling platform to simulate and optimize the NVRO Process™ flow sheet.
• Performance Highlights:
• Gold concentrate grade ↑ 286%
• Silver concentrate grade ↑ 450%
• Gold recovery in pre‑concentration validated at 82% by ALS Global
• Oxidation efficiency measured at 96.3% (enhancing downstream leaching)
• Concentrate volume reduced by 67%, lowering logistics and refining costs
• Material sent to oxidative leaching cut by 35%, reducing energy load and operating cost.
• Commercial Implications:
• Digital model provides a blueprint for rapid replication across multiple tailings sites, de‑risking deployment and shortening design time.
• Supports a capital‑light licensing approach, enabling EnviroGold to license the NVRO Process™ to major mining groups globally.
• Anticipated revenue streams include recurring royalties and net‑smelter‑return payments from licensed projects.
• Strategic Focus Areas: Licensing in the Americas, Australia, and Europe; alignment with U.S. DOE, DOI, and EU critical‑minerals mandates; promotion of circular‑economy metal recovery.
• Executive Quote: “The ANDRITZ case study is a major milestone for EnviroGold… it independently validates the NVRO Process™, supports our commercial decision‑making, and enables rapid replication across our global pipeline.” – Grant Freeman, Co‑CEO.
