Mercado Minerals completes historic core re-sampling and re-assaying at Copalito
Vancouver, British Columbia--(Newsfile Corp. - April 14, 2026) - Mercado Minerals Ltd. (CSE: MERC) (OTCQB: MRMNF) (" Mercado " or the " Company ") is pleased to report assay results from core re-sampling of historic diamond drill holes at the Copalito project. The Company is happy to report that, in general, there is excellent agreement between the re-assay drill composite intercepts and previous drill composite intercepts as reported by a previous operator. Significant Comparable Drill Intercepts: Daniel Rodriguez, CEO and Director, commented: "We were very fortunate to be able to acquire such a complete data set for the exploration work completed at Copalito.
We could tell that it was very well collected and conducted with industry best standards for mineral exploration. What we had to do was prove it, and I'm happy to say that we see very good agreement between the historic drill hole analyses and our new re-assays of identical sample intervals." Mercado inherited an extensive, high quality dataset including assay information for 81 diamond drill holes, extensive mapping and rock sampling data for the Copalito project, which has allowed the Company to undertake exploration and drill targeting programs prior to the launch of its inaugural exploration drilling program, which began on March 10, 2026. The dataset included PDF Certificates for the analytical results that Mercado personnel audited for accuracy against its accompanying digital databases.
As a final audit of the accuracy and reproducibility of the diamond drill data, the Company embarked on a re-sampling program for 12 of the 81 historic diamond drill holes. The re-sampling allowed the Mercado technical team to review the 6 principal mineralized veins that were targeted by previous drill campaigns, and gain insights on potential mineralization controls that may define higher grade areas of the veins. A complete table of re-assay composite results are presented in Table 1.
