Geological and engineering team mobilized to confirm high-grade tailings and exploration upside in Bolivar, bulk sample testing underway as Company positions for multi-jurisdictional growth.

Vancouver, BC – October 8, 2025 – ESGold Corp. (“ESGold” or the “Company”) (CSE: ESAU | OTCQB: ESAUF | FSE: Z7D) is pleased to announce that its geological and engineering team has departed for Colombia to begin on-the-ground validation and due diligence at the Planta Magdalena Project. The field program follows the recently signed Memorandum of Understanding (“MOU”) announced on August 20, 2025, and represents the next step in confirming the site’s high-grade tailings potential and broader exploration upside in the Bolívar region.

This visit underscores ESGold’s commitment to disciplined technical validation before advancing any transaction and aligns with its strategy of building a scalable, cash-flow-first clean mining platform across the Americas.

Validation and Technical Program Objectives

The Company’s field team, which includes both geological and metallurgical specialists, will focus on:

• Confirming historic tailings grades and verifying the estimated tonnage and composition of material at the Planta Magdalena site.
• Evaluating site infrastructure and logistics to determine throughput potential and integration within ESGold’s processing and clean-mining model.
• Reviewing exploration upside within the surrounding Bolívar concession area, where historical reports indicate multiple mineralized zones and extensive artisanal workings.
• Finalizing technical due diligence to support the potential transition of the MOU into a definitive joint-venture agreement.

Bulk Samples and Metallurgical Testing

ESGold also confirms that bulk samples from both Colombia and Quebec have been shipped to ALS Global in Val-d’Or for independent metallurgical analysis. On-site geological and metallurgical work will also be conducted to finalize the processing circuit and recovery parameters in preparation for site commissioning.

Results are expected shortly and will play a key role in confirming gold and silver recoveries under ESGold’s proprietary clean-processing framework.

Gordon Robb, CEO of ESGold, commented:
“With our technical team now on the ground in Colombia, we’re moving from intent to execution. This is the critical phase where we validate the data firsthand. From confirming grades and metallurgy to evaluating site infrastructure and broader geological potential. We’re also eagerly awaiting lab results confirming concentrate results for both Colombia and Quebec samples, which will help verify the metallurgy behind our clean-processing model. This marks an exciting step forward in ESGold’s strategy to build a scalable, multi-jurisdictional platform for responsible gold and silver production.”

Why This Matters to Investors

• Next step toward expansion: On-site validation at Planta Magdalena advances the MOU announced this past August toward a definitive partnership.
• Tangible progress: Bulk samples from Colombia and Quebec are in the lab, with results pending to verify recoveries and support near-term production readiness.
• Exploration upside: Field teams will also assess the potential for district-scale mineralization within the broader Bolívar region.
• Execution without dilution: ESGold remains fully funded to complete these initiatives while continuing construction at Montauban, targeting first production in 2026.

The Colombia validation program represents a major point in the Company’s evolution into a diversified, cash-flow-generating precious metals company. By combining clean reprocessing of legacy materials with systematic exploration of under-tested districts, the Company continues to advance a model built on efficiency, scalability, and shareholder value. Updates on fieldwork progress and metallurgical results from both jurisdictions will be shared as data becomes available.
