ENVIROGOLD GLOBAL ANNOUNCES POSITIVE ANDRITZ CASE STUDY CONFIRMING NVRO PROCESS™ COMMERCIAL READINESS AND GLOBAL SCALABILITY

Envirogold Global Ltd. has published 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-per-cent increase in gold and 450-per-cent increase in silver concentrate grades;
• 82-per-cent gold recovery in preconcentration was validated by ALS Global;
• 96.3-per-cent oxidation efficiency, improving downstream leaching performance;
• 67-per-cent reduction in concentrate volume for logistics and refining;
• 35-per-cent 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.

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, derisking deployment and supporting a capital-light licensing model.

"The Andritz case study is a major milestone for Envirogold," said Grant Freeman, co-chief executive officer. "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 prioritizing 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 United States Department of Energy, DOI and EU CRM mandates;
• 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.
