Exceptional Phase 3 Metallurgical Results Unveiled
EnviroGold Global Limited (CNSX: NVRO | OTCQB: ESGLF | FSE: YGK), a pioneering clean-technology company dedicated to recovering vital metals from mining waste, has recently reported remarkable achievements from the Phase 3 tests of its Rapid Deployment Pathway, particularly with its Major Tailings Reprocessing Projects.
The NVRO Process™ Achieves Breakthrough Recoveries
Through meticulous pre-concentration and tailings processing utilizing the proprietary NVRO Process™, substantial results emerged from tests conducted at ALS Laboratories. The findings are as follows:
- Gold recoveries soared to 99.55%, with silver reaching 98.96%, marking significant advancements over previous benchmarks.
- Gold concentration saw a staggering increase of 380%, from 5.5g/t to an impressive 20.9g/t.
- Silver levels in concentrates surged by 602%, advancing from 92g/t to a remarkable 554g/t.
- There was an 8% increase in base and critical metals reporting to the pregnant leach solution.
- Additionally, strong correlations between laboratory results and simulations reinforce the NVRO Process™ as both reliable and scalable.
These results affirm the tailings as prime candidates for the commercial implementation of the NVRO Process™, revealing multiple potential revenue streams from concentrates of precious metals and the extraction of base and critical metals from the leach solution. Similar impressive results have been achieved across other Phase 3 testing conducted for customers.
Emphasizing Environmental and Sustainability Impact
The tailings reprocessing strategy encompasses several environmental benefits, designed to provide:
- An astonishing 86% reduction in potential acid mine drainage by diminishing pyrite content.
- Production of 1.2 million tonnes of market-ready precious metal concentrates.
- Additional revenue generation from the recovery of base and critical metals from the leach solution.
- A reduction of 14% in the volume of on-site tailings.
Economic Opportunities from Tailings Resources
Current tailings facilities associated with this project are estimated to hold over 9 million tonnes of material, boasting an in-situ metal value surpassing USD 3 billion, predominantly consisting of gold and silver.
Next Steps in the Development Journey
The project is advancing to Phase 4 of the Rapid Deployment Pathway. This upcoming phase will be crucial for validating mass balances, recovery performances, project economics, and outlining the environmental outcomes on a larger scale.
Leadership Insights on Project Progress
Grant Freeman of EnviroGold provides insight, stating, "The Phase 3 findings not only emphasize the exceptional technical capability of the NVRO Process™ but also highlight its immense economic potential in capitalizing on metal value from tailings while concurrently delivering significant environmental benefits.”
COO Royston Denysschen added, “I take pride in our team’s achievements in 2025, particularly regarding near-total precious metal recovery and our environmentally advantageous reductions in pyrite and tailings volume. These outcomes underscore EnviroGold's commitment to responsible solutions within the global mining sector.”
