REPROCESSING & RETREATMENT
“ The Fraser Alexander and EnviroGold strategic alliance will benefit both companies, leveraging the specialist market leading technology developed by EnviroGold and the best-in-class implementation and operational capabilities of Fraser Alexander. Together we will leverage our first mover advantage in the valuable mine waste and tailings market.”
Keith Scott, Fraser Alexander CEO, said:“ Fraser Alexander have a successful track record of developing and deploying proven innovative technologies for the benefit of our TSF clients. We are excited to be working with EnviroGold, whose technology allows us to expand our TSF offerings and value added services to new and exisiting clients.”
Initially, Fraser Alexander and EnviroGold will collaborate on up to three customer opportunities from their existing customer bases. For each identified customer willing to contract for services, the parties will negotiate and formalise joint ventures( JV’ s) through definitive agreements. The MoU remains effective for three years from signing, with a provision for termination by either party with one month’ s notice or upon execution of definitive agreements for specific JVs.
In a May 2025 update, EnviroGold said that its 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. It says it is advancing client demonstration campaigns, supported by enhanced engineering datasets, an expanding patent portfolio, and strategic partnerships with industry leaders, including Andritz Group and the mentioned tie up with Fraser Alexander.
Through the application of IDEAS™ Digital Optimisation in collaboration with Andritz Group, the company says it has achieved significant process enhancements. These outcomes are expected to contribute to reduced CAPEX and OPEX, streamlined logistics costs, and a smaller environmental impact.
EnviroGold 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 AIenhanced remote operations, ESG, carbon monitoring and emission analysis.
EnviroGold has also completed initial desktop reviews for multiple high-quality prospective clients and is now initiating NVRO’ s Stage-Gate Candidate Evaluation Process- a standardised project assessment framework designed to be completed within approximately 36 weeks, compared to the industry norm of 18 to 24 months.
EnviroGold says its accelerated progress“ reflects a deliberate strategy to de-risk technology commercialisation, develop highvalue 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, it says the NVRO Process™ is positioned to unlock stranded value from legacy tailings; support environmental remediation objectives for mining companies facing heightened ESG scrutiny; and enable production of highgrade concentrates and the recovery of precious and critical metals without the impacts associated with conventional mining.
The company’ s continuing 2025 work program includes the appointment of
