ESGold Highlights Untapped Exploration Potential in Colombia's Bolívar Region with District-Scale Opportunity

Audio By Carbonatix

Historical report outlines a 3.4 km by 400-800 m corridor, high-grade channel samples up to ~170 g/t Au, and broad drill intercepts that remain untested by modern exploration technologies.

VANCOUVER, BC / ACCESS Newswire / September 30, 2025 / ESGold Corp. ("ESGold" or the "Company") (CSE:ESAU)(OTCQB:ESAUF)(FSE:Z7D) is pleased to outline the prospective potential of a concession in Colombia's Bolívar region, informed by historical NI 43-101 data and prior operator disclosures. The Bolívar district represents one of South America's most prolific artisanal gold-producing regions, with historical work pointing to the scale, grade, and structural complexity consistent with a major mineralized system.

Historical Highlights (La Pantera, Bolívar - NI 43-101, July 25, 2018*)

• Large mineralized footprint: Zone No. 6, the most important structural corridor identified, measures approximately 3.4 km in strike length and 400-800 m in width. Multiple additional zones of mineralization occur across the 1,734-hectare concession.

• Widespread artisanal production: Hundreds of small-scale workings exploit saprolite and hard rock, with historical recoveries limited by rudimentary gravity methods - tailings still carry recoverable gold.

• High-grade samples: Underground channel sampling at Mina Bulla returned assays up to ~170 g/t Au, while saprolite "head" grades averaged ~1 g/t Au in places.

• Historical drilling: 19 holes (~4,180 m) at Los Matos reported broad, lower-grade intercepts (0.4-0.6 g/t Au over tens of metres), suggesting vein clusters and stockwork-style mineralization at depth.

• Untested depth potential: No systematic geophysics or modern drilling has tested below ~200 m, leaving deeper intrusive-related mineralization untested.

Regional and Historical Context

The Bolívar region, specifically the Serranía de San Lucas belt, has long been recognized for its gold endowment. Prior operator Origin Gold outlined in 2018 that the concession contained multiple mineralized zones, highlighting Zone No. 6 as the priority target. Despite pervasive artisanal mining and encouraging high-grade samples, the property remained underexplored, with no systematic geophysics, trenching, or follow-up drilling to test the system's scale.

ESGold's Strategy: Validate, Cash Flow, Discover

ESGold intends to approach Colombia the same way it has built Montauban in Quebec:

1. Validation First - Confirmatory sampling, QA/QC, and structural mapping to verify historical results and assess the scale of Zone No. 6 and surrounding targets.

2. Cash Flow Pathways - Evaluate tailings and near-surface material for clean reprocessing potential, creating early-stage cash flow to fund systematic exploration.

3. Systematic Exploration - Apply modern geophysics (including ANT imaging), trenching, and drilling to target both shallow and deeper mineralized zones across multiple corridors.

CEO Commentary

Gordon Robb, CEO of ESGold, stated:

"What excites us about Bolívar is the combination of scale, grade, and under exploration. Historical work shows high-grade channel samples in active workings, broad mineralized intercepts from earlier drilling, and a structural corridor more than three kilometers long that has never been tested with modern exploration tools. Add to that the extensive artisanal mining, which demonstrates the persistence of gold across the district, and it's clear this is a system with exceptional potential. Our team is eager to validate the data and, if confirmed, advance a disciplined program that leverages our cash-flow-first model while unlocking what could be a district-scale gold discovery."

Why This Matters to Investors

The Bolívar concession highlights ESGold's ability to scale its dual-track model beyond Quebec:

• Large-scale footprint with multiple mineralized zones, including Zone No. 6, measuring 3.4 km by 400-800 m.

• High-grade potential with channel samples up to ~170 g/t Au, complemented by broad drill intercepts at lower grades.

• Extensive artisanal mining provides real-world validation of the system's gold endowment.

• Replication of Montauban model: low-capex, cash flow-first development funding systematic exploration, with reduced dilution.
