Mercado Minerals (OTCQB: MRMNF) reports progress on a 3,000-metre diamond drill program at the Copalito Project, Sinaloa, Mexico. As of April 21, 2026 the company completed 12 holes totaling 1,479 metres (nearly half the program) with 11 holes on the 5 Señores vein.
Drilling has moved to the El Agua vein; initial samples were sent to ALS Global. Preliminary soil data show anomalous silver, lead, zinc, gold and arsenic correlation, prompting expansion of soil sampling and continued mapping to refine drill targets.
Mercado Minerals (OTCQB: MRMNF) reported re-sampling and re-assaying results from 12 historic diamond drill holes at the Copalito project dated April 14, 2026. Results show strong overall agreement with prior assays across multiple veins, validating the acquired dataset of 81 drill holes and supporting recent targeting ahead of inaugural 2026 drilling.
Where differences occur, Mercado attributes them to natural deposit variability and documented missing specimen core intervals; full re-assay tables and QA/QC procedures are provided.
