Two companies released results from drilling campaigns in Mexico during the week.

Heliostar Metals released the first results from drilling at the San Agustín project since its acquisition. The company is to invest US$9.75 M in resources and reserve oxides drilling in 2026, with the program involving 15,000 to 18,000 m of drilling. To date Heliostar has completed 7,230 m in 75 holes in three of eight target areas, namely Corner Expansion, Phase 3 SW and MKT zones. “Encouraging results at the Corner Expansion Zone have driven the decision to expand the drill program to define a potential resource. This drilling will include both core and reverse circulation (“RC”) ….. This will allow Heliostar to gather the engineering and metallurgy information required to evaluate an additional pit layback beyond the reserve that is currently being mined”. From the project’s technical report the “San Agustin deposit is an intermediate sulfidation style epithermal gold-silver system with vertical base-metal zonation associated with a dacite dome complex. Early potassic alteration could be associated to tourmaline breccias with a possible genetic connection to a porphyry that may be located either vertically or laterally to the deposit.”

Southern Silver Exploration reported assays from drilling at the Puro Corazon claim within its Cerro Las Minitas project in Durango. This update includes results from the current program and the extension of a hole collared in 2012. “Mineralization in these holes is localized within the skarn-altered halo immediately adjacent to the central intrusion or alternatively, form carbonate replacement zones, further out-board from the intrusive body at the skarn / marble transition”. Twenty three holes have been completed on this program, and the drill crews have been demobilized.
