Canadian Miner Esgold (CSE: ESAU) (OTCQB: ESAUF) Reports MOU For High-Grade Tailings Project In Colombia

This strategic move represents a significant step in ESGold's plan to expand its tailings-to-cash-flow model beyond Qubec, applying modern, environmentally responsible processing to legacy tailings in one of South America's most prolific gold-producing regions. The Company aims to generate high-margin, scalable production while delivering environmental remediation benefits and positioning itself for further growth across the Americas.

• Structure & Consideration: ESGold will contribute C$1.5 million for a 50% JV interest and will hold a first right of refusal to purchase the remaining 50% within 12 months at fair market value determined by independent third-party appraisal.
• Permitting: Planta advises that it holds permits to commence tailings production. ESGold will conduct independent verification of all permits and licences as part of its due diligence prior to entering into a definitive agreement.
• Strategic Rationale: The Bolvar JV is designed to replicate ESGold's low-capex, high-margin tailings model developed at Montauban (Qubec), while remediating legacy mine sites and improving environmental outcomes for local communities.
• Fast-Track Workplan: Preliminary due-diligence fire-assay sampling of tailings (27 samples) has been completed. Concentrate tests on the assayed tailings are being finalized at Montauban and will be shipped to ACTLABS in Val-d'Or for analysis. On-site geological and metallurgical visits are being scheduled to finalize the proposed circuit and recovery parameters.
• Path to Production: Subject to a definitive agreement, verification, and commissioning, the Company's objective is to add a second high-margin operation alongside Montauban, with a target start-up in 2026.

As part of joint ESGold-Planta due diligence, 27 tailings samples were collected across the tailings sector and submitted to ACTLABS. Highlights (sample IDs as received) include:

• SS806: 42.683 g/t Au
• SS816: 19.284 g/t Au
• SS817: 18.332 g/t Au
• SS825: 10.787 g/t Au

In total, 8 of 27 samples assayed above 5 g/t Au, including several high-grade results; multiple samples also returned notable silver values exceeding 190 g/t Ag.

Cautionary Note: Samples are selective and may not be representative. No mineral resource or reserve is declared.

ESGold is finalizing bulk-sample concentrate tests to confirm recovery rates for the proposed mining circuit. Testing will be completed at the Company's Montauban facilities with confirmed assays at ACTLABS in Qubec on an expedited basis.

The Department of Bolvar is recognized as one of Colombia's most prolific gold-producing regions, with a mining tradition that spans centuries. Today, artisanal and small-scale miners in the region collectively process an estimated 300,000 tonnes of ore annually, producing approximately 128,000 ounces of gold. Despite this significant output, much of the material is processed using rudimentary mercury amalgamation methods, which typically recover less than half of the contained gold and silver.

This long-standing reliance on outdated technology leaves a substantial portion of precious metals unrecovered in the tailings. Modern, mercury-free processing techniques can materially improve recovery rates while eliminating the environmental harm caused by mercury. The combination of a large, continuous feed of tailings, a skilled local workforce, and the region's established mining infrastructure creates a unique opportunity to launch a high-margin, environmentally responsible operation with near-term scalability potential.

By starting in Bolvar, ESGold positions itself to demonstrate the economic advantages of its tailings-to-cash flow model in one of South America's most prolific gold-bearing districts, while delivering tangible environmental remediation benefits to local communities.

• Definitive Agreement: Finalize binding terms with Planta Magdalena following the completion of legal, technical, and financial due diligence. This includes title and lien verification, litigation search, licensing and permitting review, and confirmation of compliance with Colombian mining and environmental regulations.
• Technical Verification: Conduct QP-supervised site visits to the Bolvar project for systematic tailings sampling, full QA/QC protocols, metallurgical recovery testing, and circuit engineering design. The Company foresees this to occur in the beginning of September.
• Bulk Concentrate Testing: Finalize ongoing bulk-sample concentrate tests from Planta Magdalena to confirm recovery rates for the proposed mining circuit. Testing will be completed at the Company's Montauban facilities with confirmed assays at ACTLABS in Qubec on an expedited basis.
• Montauban Development: Continue construction and commissioning work at Montauban, where concentrate testing and process fine-tuning are progressing well. A detailed 3D geological model is nearing completion to refine high-priority drill targets, and the updated Preliminary Economic Assessment (PEA) will incorporate enhanced economics to reflect higher metal prices.
• Implementation Planning: For the Bolvar JV, confirm and validate all operational frameworks, develop a localized community engagement plan, and finalize environmental management measures consistent with ESGold's clean-processing standards.

With Montauban fully permitted and under construction in Qubec, the Bolvar opportunity marks a pivotal step toward building a scalable, self-funded, high-margin platform for precious metals production across the Americas. By securing permitted tailings projects in prolific mining districts, ESGold can generate predictable, repeatable cash flow that funds exploration and discovery without relying on continual equity dilution. This disciplined model pairs near-term production with the upside of exploration, creating a balance of stability and growth rarely seen in the sector. Coupled with our commitment to environmental remediation and community benefits, this strategy positions ESGold to compound value over time, transforming legacy mine waste into both shareholder returns and lasting positive impact across multiple jurisdictions.
