EnviroGold's Greens Creek Test Results Bolster Tailings Recovery Strategy
Event summary
- EnviroGold Global has completed Phase 2 testing of tailings from Hecla Mining’s Greens Creek Mine in Alaska.
- Phase 2 results indicate near-complete oxidation of sulfide minerals and high recovery rates: 98.07% silver and 99.46% gold.
- A bulk sample is being shipped to EnviroGold’s West Australian facility for Phase 3 and 4 pilot plant optimization and demonstration-scale processing.
- Hecla was previously referred to as a 'North American Tier-1 customer' but is now publicly identified.
The big picture
EnviroGold’s success hinges on the growing demand for sustainable mining practices and the recovery of critical minerals from existing waste streams. The company's NVRO Process addresses a significant environmental liability for mining companies while potentially unlocking substantial metal value. This project with Hecla, a major North American miner, validates the technology and opens the door for EnviroGold to pursue similar opportunities with other operators facing increasing ESG pressure.
What we're watching
- Scale-Up Risk
- The successful transition of the NVRO Process from laboratory testing to industrial-scale operations remains a key risk, as demonstrated recoveries may not be replicated at larger volumes.
- Commercialization
- The ability of EnviroGold to secure long-term commercial arrangements with Hecla, or other mining companies, will be crucial for realizing the potential value of the tailings recovery strategy.
- Regulatory Approval
- Securing necessary permits and regulatory approvals for industrial-scale tailings processing operations could be a lengthy and uncertain process, potentially delaying project timelines.
