Thirteen companies released lead and/or zinc results from twelve drilling programs in Mexico during the first quarter of 2025. The best results for both lead and zinc are from Silver Storm’s La Parrilla project in Durango, with a reported core length interval of 18.04 m averaging 4.3% Pb, 5.0% Zn.

Four of the twelve properties present intermediate sulfidation epithermal mineralization, including Alamos Silver and El Tigre in Sonora, Tahuehueto in Durango and Columba in Chihuahua. Two more properties, Gran Pilar/El Pilar in Sonora and Cristina in Chihuahua also display intermediate sulfidation epithermal mineralization, but probably distal to porphyry copper systems. Two projects present carbonate replacement mineralization (CRD), Plomosas in Chihuahua and Ana Maria in Durango. An additional two properties present skarn mineralization: Cerro Las Minitas in Durango and Bolivar in Chihuahua, although the latter could be related also to a porphyry copper system. At La Parrilla, in Durango, carbonate replacement is the most prominent mineralization, but also skarn and intermediate sulfidation epithermal are present. Finally, At Panuco in Sinaloa the mineralization straddles the gap between low and intermediates sulfidation epithermal systems.

To note is that eleven of the twelve properties with reported lead-zinc intercepts are located in only three adjacent states: Sonora, Chihuahua and Durango.
