Mercado Minerals Completes Historic Drill Core Re-Sampling and Re-Assaying Program at the Copalito Project
Mercado Minerals Validates Historical Data to Clear Path for Copalito Drilling Campaign

Executive Summary
- Event: Completion of historic drill core re-sampling and re-assaying program at the Copalito Project (Sinaloa, Mexico).
- Objective: Validate reliability of 81 historical diamond drill holes inherited from previous operators.
- Results: Excellent agreement between new assay intercepts and original historical data reported by previous operators.
- Key Intercepts Validated:
- BDH-20-004 (5 Señores Vein): 379 g/t Ag, 0.30 g/t Au over 13.10 m.
- BDH-21-055 (Agua Vein): 118 g/t Ag, 2.12 g/t Au over 23.00 m.
- Multiple other high-grade silver-gold intercepts confirmed across 5 Señores and Agua veins.
- QA/QC: Samples analyzed by ALS Laboratories in Hermosillo; fire assay with atomic absorption/gravimetric finish used for gold.
- Context: Validation follows the launch of the inaugural 3,000-metre diamond drill program (March 10, 2026).
- Management Commentary: CEO Daniel Rodriguez confirmed the dataset was collected to industry best standards and now verified by Mercado Minerals.
Material Impact
- Validation vs. Discovery: The news confirms data integrity but does not present new mineralization discovery. It is a technical validation step rather than a resource update.
- Risk Mitigation: Removes investor skepticism regarding the quality of inherited historical data, which was a prerequisite for launching the current drill program.
- Market Expectation: Given the drill program commenced in March 2026 and this news arrived in April 2026, the market likely anticipated QA/QC completion before drilling results were released.
- Price Action Context: Stock price has declined significantly from December highs ($0.47) to current levels (~$0.20), suggesting prior skepticism or sector weakness. This news stabilizes the technical thesis but does not immediately reverse the downtrend without new drill assay results.
- Catalyst Status: Positive operational milestone, but the true material catalyst remains the new drill hole assays from the 3,000-metre program currently underway.
