Envirogold gets Andritz study backing NVRO readiness

Executive Summary

• Envirogold Global Ltd. published an independent case study by Andritz validating the performance and commercial scalability of its proprietary NVRO Process for recovering metals from mine waste.
• The study confirms significant enhancements in recovery rates, concentrate grades, and operating efficiency, supporting the company's strategy to license the technology and deploy modular plants globally.
• The validation aligns with Envirogold's capital-light licensing model and positions the company to pursue commercial project commitments in the U.S., Australia, and Europe.

Key Details

• Source: Independent case study by Andritz, a global leader in engineering and industrial simulation, released as part of its "Ideas" digital-modelling success series.
• Process Validated: NVRO Process, Envirogold's clean-technology solution for recovering precious, base, and critical metals from mine waste/tailings.
• Performance Metrics (Andritz Ideas Simulation Platform):
  • 286% increase in gold concentrate grade.
  • 450% increase in silver concentrate grade.
  • 82% gold recovery in preconcentration (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.
• Technical Alignment: The optimization model aligns closely with Envirogold's lab and pilot results, confirming underlying chemistry, mass balance, and metallurgical performance.
• Commercial Strategy:
  • 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. Department of Energy, DOI, and EU CRM mandates.
  • Generating recurring royalty and net smelter return revenue streams.
• Strategic Impact: The digital foundation allows for rapid replication and scaling of the system across multiple global projects, reducing design time and derisking deployment.

Notable Quotes

• "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. This is exactly the kind of rigorous, third party confirmation needed to scale sustainably and profitably." — Grant Freeman, Co-Chief Executive Officer
• "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 prioritizing critical minerals recovery from mine waste and tailings." — Grant Freeman, Co-Chief Executive Officer
