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.
