Mexico’s Best Drilling Intercepts, Fifth Week of April 2026

/ Gambusino Prospector / Leave a comment

Three companies announced results from drilling campaigns in Mexico during the week.

Luca Mining announced underground drilling results targeting the Largo Norte zone at its Campo Morado mine in Guerrero. The drill holes are expanding mineralization on the 650 m long 20 to 60 m thick unmined orebody. “To date, 47 underground diamond drillholes totaling 10,880m have been completed at the Campo Morado mine … These underground drillholes are focused on the definition of mineable resources proximal to existing underground workings … “. Campo Morado is a volcanogenic massive sulfide (VMS) deposit.

Mercado Minerals presented results from the first three holes drilled at the Copalito project in Sinaloa. These holes proved the continuation of the Cinco Señores vein, and the next holes are to test El Agua and El Pilar veins. Mineralization at the property has been described as of low to intermediate sulfidation epithermal affinity.

Silver Storm released exploration and infill drilling results from the San Nicolas zone, part of the Quebradillas mine at its La Parrilla property in Durango. Drilling has established mineralization 90 m above and 85 m below mined stopes. “The San Nicolas Zone is comprised of subvertical quartz-carbonate vein and breccia mineralization striking northwest over approximately 600 m. Sulphide replacement zones occur within the hanging wall and footwall along the bedding within the sediments. The sulphide mineralization is comprised of pyrite, galena, sphalerite, acanthite, and native silver. A second set of east-west trending sulphide-bearing quartz-carbonate veins crosscuts the principal northwest trend. Breccia pipes (chimneys) form at the intersection of these two trends.”
