EnviroGold Global Limited (CSE: NVRO | OTCQB: ESGLF | FSE: YGK) ("EnviroGold" or the "Company") is pleased to announce the publication of an independent case study by ANDRITZ, a global leader in engineering and industrial simulation, validating the performance and commercial scalability of the Company's proprietary NVRO Process™.
The study, released by ANDRITZ as part of its IDEAS™ digital-modelling success series, of customer tailings, confirms that the NVRO Process™, EnviroGold's clean-technology solution for recovering precious, base and critical metals from mine waste, achieves significant enhancements in recovery, concentrate grade, and operating efficiency. These results directly support the Company's commercialization strategy and global project pipeline.
Key Findings from the ANDRITZ Case Study
Using the IDEAS™ simulation platform, ANDRITZ modelled and optimized the NVRO Process™ flow sheet, demonstrating:
- 286% increase in gold and 450% increase in silver concentrate grades
- 82% gold recovery in pre-concentration was validated by ALS Global
- 96.3% oxidation efficiency, improving downstream leaching performance
- 67% reduction in concentrate volume for logistics and refining
- 35% reduction in material sent to oxidative leaching, lowering cost and energy load
The ANDRITZ report confirms the NVRO Process™ can be modelled with high accuracy, providing the digital foundation to rapidly replicate and scale the system across multiple global projects.
Third-Party Validation Strengthens EnviroGold's Commercialization Pathway
This is the first comprehensive third-party digital case study of the NVRO Process™ with ANDRITZ's findings providing: https://www.andritz.com/metris-en/success-stories/envirogold-success-story
Technical Validation
The optimization model aligns closely with EnviroGold's lab and pilot results, confirming the underlying chemistry, mass balance, and metallurgical performance of the process.
Commercial Readiness
The IDEAS™ model assists EnviroGold to interpret, understand and rapidly deploy the NVRO Process™ across a wide range of sulphidic tailings sites globally.
Scalable Engineering Platform
Digital replication through IDEAS™ provides the blueprint for fast, efficient engineering across future projects reducing design time, de-risking deployment and supporting a capital-light licensing model.
"The ANDRITZ case study is a major milestone for EnviroGold", said Grant Freeman, Co-CEO. "It independently validates the NVRO Process™, supports our commercial decision-making, and enables rapid replication across our global pipeline. This is exactly the kind of rigorous, third-party confirmation needed to scale sustainably and profitably".
"The combination of third-party validation, engineering readiness and strong economics underpins our global scalability. This work strengthens our engagements in the U.S., Australia and European regions now prioritising critical-minerals recovery from mine waste and tailings."
Positioned for Global Scale
The ANDRITZ study aligns with EnviroGold's commercialization strategy, focused on:
- Licensing the NVRO Process™ to major mining groups;
- Deploying modular plants across the Americas, Australia, and Europe;
- Supporting circular-economy metals recovery, aligned with U.S. DOE, DOI and EU CRM mandates; and
- Delivering recurring royalty and net-smelter-return revenue streams.
With the NVRO Process™ now validated across digital, lab and pilot stages, the Company is advancing toward commercial project commitments.
