Process Optimisation, Strategic Alliances and Engineering Readiness Position Company for Market Entry

TORONTO, May 15, 2025 (GLOBE NEWSWIRE) -- EnviroGold Global Limited (CSE: NVRO | OTCQB: ESGLF | FSE: YGK) (“EnviroGold,” or the “Company”), a clean-technology leader in reprocessing mine tailings and waste to recover precious and critical metals, is pleased to provide an operational update highlighting a series of recent strategic milestones that demonstrate meaningful progress toward the development of scalable operations.

EnviroGold’s proprietary NVRO Process™ is progressing toward commercialisation, following independent validation, and digital optimisation. The technology is designed for cost-effective, high-impact application across a range of global mining jurisdictions. The Company is advancing client demonstration campaigns, supported by enhanced engineering datasets, an expanding patent portfolio, and strategic partnerships with industry leaders, including Andritz Group and Fraser Alexander.

2025 Operational Highlights & Strategic Milestones

Through the application of IDEAS™ Digital Optimisation in collaboration with Andritz Group, the Company achieved significant process enhancements. These outcomes are expected to contribute to reduced CAPEX and OPEX, streamlined logistics costs, and a smaller environmental impact.

The Company has expanded its global IP protection through a Patent Cooperation Treaty (PCT) filing covering recent circuit refinements, thereby strengthening its IP portfolio.

The Company’s demonstration plant was commissioned in 2024 and is currently being modified to reflect the optimised flowsheet. The first client-tailings campaign utilising the updated configuration is scheduled to commence in the third quarter of 2025, with a second campaign planned for the fourth quarter of 2025.

Through the development of a Digital Twin Deployment Pathway, the NVRO Process™ has been translated into a digitally modelled plant capable of predictive simulation, performance benchmarking, and enabling future capabilities such as AI-enhanced remote operations, ESG, carbon monitoring and emission analysis.

The strategic alliance with Fraser Alexander has positioned the Company to provide turnkey, on-site deployment, from tailings reprocessing to safe tailings emplacement, supported by early-stage joint engagement with prospective customers.

The Company has completed initial desktop reviews for multiple high-quality prospective clients and is now initiating NVRO’s Stage-Gate Candidate Evaluation Process— a standardized project assessment framework designed to be completed within approximately 36 weeks, compared to the industry norm of 18 to 24 months.

EnviroGold’s accelerated progress reflects a deliberate strategy to de-risk technology commercialisation, develop high-value IP, and deliver a scalable, ESG-aligned solution targeting the global opportunity in mine tailings reprocessing.

With a rapidly advancing pipeline of prospective clients and the demonstrated ability to produce saleable metal products and refined Pregnant Leach Solution (PLS) for downstream processing, the NVRO Process™ is positioned to:

• Unlock stranded value from legacy tailings
• Support environmental remediation objectives for mining companies facing heightened ESG scrutiny
• Enable production of high-grade concentrates and the recovery of precious and critical metals without the impacts associated with conventional mining
  

Looking Ahead

The Company’s continuing 2025 work program includes:

• The appointment of a Tier-One engineering firm to conduct a comprehensive techno-economic study
• The company has earmarked individuals with the required skills to accelerate the deployment plan
• The engineering report will be completed and provide updated CAPEX, OPEX and 3D design of key equipment
• Updated economic model
• Completion of first paid client demonstration campaigns
• Advancement of downstream PLS processing strategies

“In just over a year, we’ve transformed the NVRO Process™ into an optimised, engineering-scale solution that is rapidly progressing to commercialisation. Our newly established team has made material progress over the last year,” said David Cam, CEO of EnviroGold. “Our optimisation program with Andritz has delivered meaningful improvements to projected economics, product quality, and sustainability credentials. As we move toward client demonstration campaigns and final engineering deliverables, EnviroGold is well-positioned to support a new era of ‘metals without mining’—offering incremental returns, reduced environmental impact, and strategic value for partners and shareholders.”
