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

/ Gambusino Prospector / Leave a comment

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

Heliostar Metals reported assay results from five holes that are infilling the High Grade Panel at its Ana Paula project in Guerrero. Another fourteen holes on the same area are awaiting results, same that are to add to the information gathering for an upcoming feasibility study (FS) and the future mine plan. “Mineralization at Ana Paula occurs as disseminations or vein stockworks with variable controls including rock porosity, lithology and fault networks” interpreted to be a high level example of the gold skarn mineralization on the other large deposits present in the Guerrero Gold Belt.

Impact Silver announced results from two holes drilled in the SE Area of the San Marcial deposit at its Plomosas project in Sinaloa, confirming mineralization up to 500 m downdip from surface. Two rigs are on site and additional rigs are in transit to “complete the planned 20,000 metres by H2 2026”. Recent drilling “has delineated wide, high-grade, shallow hydrothermal breccias in the San Marcial Area, including the SE Area discovery” in this intermediate to low sulfidation epithermal mineralization.

Impact Silver released surface drill results on the northern extension of the Carlos Pacheco vein system at its Noche Buena mine in the Royal Mines of Zacualpan District in Estado de México. The district is known for its precious metals intermediate sulfidation mineralization.

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

Mercado Minerals reported assay results from resampling of historic diamond drill holes at the Copalito project in Sinaloa, proving a good correspondence between the re-assay drill composite intercepts and the previous ones. The company re-sampled 12 of the 81 historic diamond drill holes. Copalito mineralization is described as having low to intermediate sulfidation affinity.

Pacifica Silver announced results from the first 16 holes of its phase II, 20,000 m diamond drilling campaign at its Caludia project in Durango. Fourteen holes were collared on the Aguilareña area and two more on the Central vein; to date 9,918 m in 38 holes have been completed. The Claudia project comprises low sulfidation epithermal mineralization in multiple veins
