Four companies reported assays from drilling at their properties in Mexico. Torex Gold results from El Limón Guajes underground stole the show with its striking high gold values over lengthily intercepts on infill and step-out holes. Over 34,000 m of drilling have been performed to the end of May on the 2023 program. The press release included a good description of the mineralization at the property: “Gold mineralization at ELG occurs in association with a skarn body that was developed along a 2-kilometre long corridor following the northeast contact of the ELG granodiorite stock. The skarn zone that occurs at the marble stratigraphic level of the Morelos Formation is in contact with hornfels developed in the Mezcala Formation. At El Limón, skarn mineralization is also structurally controlled by NE-SW and WNW-ESE trending faults and fracture zones. Skarn alteration and mineralization at ELG are fairly typical of calcic gold-skarn systems. Zones of coarse, massive, garnet-dominant skarn appear within and along the stock margin, with finegrained pyroxene-dominant skarn more common at greater distances from the contact with the stock. Significant gold mineralization at ELG is associated with the skarn, preferentially occurring in pyroxene-rich exoskarn but also hosted in garnet-rich endoskarn that has been affected by retrograde alteration. Pre- and post-mineralization dykes and sills are found to crosscut the hornfels and marble, along the structural trends mentioned above, and are spatially associated with the skarn formation. The style of mineralization at El Limón Sur Deep is like Sub-Sill and ELD, and is characterized by gold, with locally high silver and copper grades. Gold occurs in variably sulfidized, pyrrhotite-rich skarn, while silver and copper mineralization is controlled primarily by the degree of sulfidation of the host skarn. Mineralization is mainly associated with retrograde alteration characterized by the occurrence of phlogopite, amphibole, chlorite, calcite and lesser amounts of quartz and epidote, and local magnetite”.

The three other press releases are from low to intermediate sulfidation epithermal systems, namely Vizsla Silver’s Panuco project in Sinaloa, Sierra Madre Gold and Silver’s La tigra project in Nayarit and Prime Mining’s Los Reyes property in Sinaloa.
