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

Americas Gold and Silver presented results from its ongoing resource conversion drilling program at the Cosalá Complex in Sinaloa. Drilling was conducted in Q4 2025 through Q1 2026 at the San Rafael Upper, 120 Upper and 120 Lower zones. Mineralization at the project presents skarn and carbonate replacement (CRD) characteristics, related to at least three intrusive phases.

Advance Metals released results from the first hole in their maiden drilling campaign at its Gavilanes project in Durango. The company’s first hole was drilled to a depth of 276 m and intersected a broad zone of silver mineralization approximately 80 m down dip to the west of a high-grade zone previously defined in an historic hole. Mineralization at Gavilanes is of intermediate sulfidation epithermal characteristics.

Tocvan Ventures reported results from the exploration drilling campaign at its Gran Pilar project in Sonora. Significant gold results were obtained in three new areas within the South Block: El Mezquite Trend South, Mag High Target and New Eastern Trend. Mineralization at the project seems to be of epithermal characteristics, linked to the outer parts of a porphyry copper system.
