Mexico’s Best Drilling Intercepts, Fifth Week of May 2025

Only First Majestic Silver released results from drilling campaigns in Mexico during the week, with intercepts from the Santo Niño, Navidad and Winter veins at its Santa Elena mine in Sonora. The Navida and Winter veins are adjacent to the Ermitaño deposit, currently being mined, while the Santo Niño vein is a new discovery located 900 m south from the Santa Elena processing plant. “By drilling beneath the masking andesitic cover into the prospective rhyolite horizon, geologists intercepted the Santo Niño vein and delineated zones of high-grade mineralization. Large portions of the Santa Elena concession, where this rhyolite is concealed, have not yet been explored”.

The Santo Niño vein is on a newly identified fault zone over 1 km in length and 400 m downdip, with mineralization having been confirmed for more than 600 m along strike and 220 m downdip and open in several directions. The mineralized zone is 1 m to 12.3 m thick, averaging 4.5 m, with true-width intercepts of up to 12.34 m @ 1.65 gpt Au, 113 gpt Ag and 1.91 m @ 8.38 gpt Au, 248 gpt Ag (including 0.43 m @ 27.50 gpt Au, 641 gpt Ag).

The Navidad/Winter vein system delivered assay grades exceeding those from prior drilling in the mineral resource estimate, with step-out and in-fill holes having traced the combined structure for 1.3 km along strike and 450 m down dip. Highlighted true-width intercepts comprise 6.81 m @ 14.77 gpt Au, 642 gpt Ag; 5.89 m @ 11.11 gpt Au, 215 gpt Ag; 2.47 bm @ 21.22 gpt Au, 1,093 gpt Ag.
