Mexico’s Best Drilling Intercepts, Second Week of April 2026
Two companies announced results from drilling campaigns in Mexico during the week. Included in the table below are also the intervals from drilling at Cosalá by Americas Gold Silver, same that were published the previous week and omitted in the respective compilation.
Heliostar Metals presented results from six holes on the Expansion Zone below the High Grade Panel at its Ana Paula project in Guerrero, where the company has completed 28,318 m in 84 holes during its 2025-2026 drill campaign. Ana Paula is within the Guerrero Gold Belt, which is characterized by gold bearing skarns. At the project mineralization has been described to be mainly in a sulfide rich breccia, replacement bodies and minor skarn bodies, with a late epithermal overprint. The present press release states “We interpret Ana Paula to be higher in the same geological setting as its large neighbours in the Guerrero Gold Belt… Mineralization at Ana Paula occurs as disseminations or vein stockworks with variable controls including rock porosity, lithology and fault networks”.
Mithril Silver and Gold presented results from drilling on Targets 3 and 5 at its Copalquín project in Durango. High-grade gold-silver mineralization is hosted by low sulfidation epithermal mineralization in volcanic rocks of the Sierra Madre, although in narrow veins in the present release.
Americas Gold and Silver released results from resource definition and exploration drilling at its Cosalá mine in Sinaloa. The program is focusing on upgrading resource classifications on the UZ and Zone 120 deposits and exploration of the El Alacrán discovery zone.
Mexico’s Best Copper Drilling Intercepts, First Quarter 2026
Eight companies released copper results from drilling programs in Mexico during the first quarter of 2026. The best copper intercept is from Luca Mining’s drilling at Campo Morado in Guerrero, with 135.7 m averaging 0.88% Cu. The underground diamond drilling results are from the Largo Norte Zone, near current mining operations in this volcanogenic massive sulfides deposit (VMS).
For a short table like this one it is striking the diversity of mineralization styles present. The most common deposit type is intermediate sulfidation epithermal, of which there are three examples at the lower end: Tahuehueto, La Colorada (Zacatecas) and Alamos Silver. Mineralization at La Huerta is described as of iron-oxide-copper-gold (IOCG) affinity, Cerro Las Minitas presents skarn and carbonate replacement mineralization, whereas Adelita can be defined as a skarn distal to a porphyry copper system, and Dios Padre as a strongly zoned Au-Cu-Ag breccia related to a porphyry copper system.
