EnviroGold Global Limited (TSX-V: NVRO | OTCQB: ESGLF | FSE: YGK) ("EnviroGold" or the "Company"), a clean technology company focused on the recovery of precious and critical metals from mine waste and tailings, announces the successful completion of Phase 2 of its structured test work program on tailings from Hecla Mining Company ("Hecla")'s Greens Creek Mine in Alaska. The Company previously described this party as a "North American Tier-1 customer" due to confidentiality considerations; it is now able to identify Hecla as the counterparty for this project.
Completion of Phases 1 and 2 of EnviroGold's Rapid Deployment Pathway confirms the technical suitability of the Greens Creek tailings for the NVRO Process™, demonstrating near-complete oxidation of sulfide minerals and strong liberation of contained metals, achieving high recovery rates, including 98.07% silver and 99.46% gold.
A bulk sample of feedstock from Greens Creek is in process of being shipped to EnviroGold's West Australian project development facility, where Phase 3 pilot plant optimization and Phase 4 demonstration-scale processing is to be completed.
These phases are designed to optimize the process operating conditions, validate saleable product quality and value, evaluate waste stream characteristics and operating parameters at industrial scale, and generate engineering data for techno-economic modelling to support continued commercial evaluation of the tailings processing opportunity.
Subject to further study, approvals and commercial arrangements, the project has the potential to recover silver, gold, base metals and critical minerals from sulfidic tailings using the NVRO Process™ while reducing long-term environmental liabilities associated with legacy mine waste. "The test work results clearly demonstrate the NVRO Process™ has the potential to unlock significant metal production from mineralization contained in Greens Creek's tailings facility, material that was not recovered in prior milling activities over the facility's 35-year operational history," said Grant Freeman, Chief Executive Officer. "We are grateful to Hecla for the opportunity to assess their tailings and the potential commercial opportunity."

Forward-Looking Statements
This news release contains "forward-looking statements" within the meaning of applicable securities laws. Forward-looking statements are generally identified by words such as "expect," "plan," "anticipate," "intend," "estimate," "believe," "may," "will," "should," "could," "potential," and similar expressions. Forward-looking statements in this news release include, but are not limited to, statements regarding: the completion and timing of Phase 3 pilot plant optimization and Phase 4 demonstration-scale processing; the objectives and expected outcomes of Phases 3 and 4, including optimization of operating conditions, validation of saleable product quality and value, assessment of waste-stream characteristics and operating parameters at industrial scale, and generation of engineering data for techno-economic modelling; the technical suitability of the Greens Creek tailings for processing using the NVRO Process™ and the ability to achieve recoveries or other performance results at larger scale consistent with test work results; the potential to recover silver, gold, base metals and critical minerals from sulfidic tailings using the NVRO Process™; the potential environmental benefits of tailings and mine-waste reprocessing, including reduction of long-term environmental liabilities; the Company's ability to progress commercial evaluation and, if successful, enter into commercial arrangements in respect of the Greens Creek tailings opportunity; and any statements regarding the estimated gross metal value of the Greens Creek tailings and related assumptions.
Forward-looking statements are based on management's current expectations, assumptions and beliefs as of the date hereof, including, without limitation: that the bulk sample is representative of the Greens Creek tailings relevant to the opportunity being evaluated; that metallurgical test work results are indicative of performance at pilot, demonstration and commercial scale; that further test work, engineering studies and techno-economic modelling will support continued evaluation; that required equipment, reagents, utilities, personnel, and third-party services will be available on acceptable terms and within anticipated timelines; that required permits, regulatory approvals and stakeholder support (including from counterparties and relevant authorities) will be obtained on a timely basis; that the Company will be able to negotiate and enter into commercial arrangements on acceptable terms; and that commodity prices, foreign exchange rates, inflation, logistics and supply-chain conditions will remain sufficiently supportive of continued evaluation.
Actual results may differ materially from those expressed or implied by forward-looking statements due to risks and uncertainties, including, without limitation: variability in tailings characteristics and metallurgical response; differences between laboratory, pilot, demonstration and commercial-scale performance; technical or operational challenges, including equipment performance, recoveries, impurities, product specifications, and waste-stream management; delays or failure in completing Phases 3 and/or 4 on anticipated timelines or achieving intended outcomes; errors or changes in assumptions used in techno-economic modelling or any gross metal value estimate; changes in commodity prices, foreign exchange rates, interest rates, inflation or market conditions; availability of financing; permitting, regulatory or approval delays; inability to secure commercial agreements or strategic partnerships on acceptable terms or timelines; health, safety and environmental risks; changes in laws, regulations or government policy; and other risks and uncertainties beyond the Company's control. This list is not exhaustive.
Forward-looking statements are not guarantees of future performance and involve risks, uncertainties and assumptions that are difficult to predict. Readers are cautioned not to place undue reliance on forward-looking statements. Except as required by applicable securities laws, the Company disclaims any obligation to update or revise any forward-looking statements to reflect new information, future events or otherwise.
