EnviroGold Global Announces Positive Results from Hecla Mining Company’s Greens Creek Tailings

Core Viewpoint - EnviroGold Global Limited has successfully completed Phase 2 of its test work program on tailings from Hecla Mining Company's Greens Creek Mine, demonstrating the potential for high recovery rates of precious metals using its proprietary NVRO Process™ [1][2][5]. Group 1: Project Development - The completion of Phases 1 and 2 confirms the technical suitability of the Greens Creek tailings for the NVRO Process™, achieving recovery rates of 98.07% for silver and 99.46% for gold [2]. - A bulk sample from Greens Creek is being shipped to EnviroGold's facility in West Australia for further pilot plant optimization and demonstration-scale processing [3]. - Phases 3 and 4 are designed to optimize process conditions, validate product quality, evaluate waste stream characteristics, and generate engineering data for techno-economic modeling [4]. Group 2: Environmental and Commercial Potential - The project aims to recover silver, gold, base metals, and critical minerals from sulfidic tailings while reducing long-term environmental liabilities associated with legacy mine waste [5]. - The NVRO Process™ has the potential to unlock significant metal production from the Greens Creek tailings, which were not recovered during the mine's 35-year operational history [5]. - The company emphasizes the alignment of its operations with global ESG frameworks and critical minerals strategies, providing scalable and lower-impact metal recovery solutions [6].
