Three companies released results from drilling campaigns in Mexico during the week. Kootenay Silver is testing three areas at its Columba project in Chihuahua, the I, D and B veins, focusing on testing extensions and gaps in advance of the preparation of a maiden resource estimate. The project comprises a district scale intermediate sulfidation epithermal system in which mineralization is assumed to be just barely exposed by erosion.

In Guanajuato, The Valenciana Mine Complex is being explored by underground drilling at the Cata mine area, where 679 m of drilling were completed in six holes, and the Maravillas zone, tested with 615 m of drilling in three holes. “The Cata deposit is located at an inflection point of the Veta
Madre structure …… four main veins have been identified: Alto 1, Alto 2, Alto 3 and Alto 4.”

Silver Storm Mining presented results from nine holes from the La Estrella and San Rafael zones of the Quebradillas mine at its La Parrilla project in Durango. “The La Estrella Zone is a sulphide-bearing hydrothermal breccia within a fault …… over an approximate strike length of 225 m” and “The San Rafael Zone is a sulphide-bearing tectonic breccia zone …. with a known strike length of approximately 120 m”. Mineralization at La Parrilla project is complex, associated to the intrusion of an Eocene igneous stock and dikes into an Early Cretaceous sedimentary sequence. Intrusion-related carbonate replacement deposits and mesothermal fault-veins were proposed in the 2023 technical report as mineralization models, although skarn, skarnoid, hornfels and marble are mentioned as alteration assemblages.
