This week three companies posted drilling results from properties in Mexico. By a long shot Heliostar’s intercepts on the Ana Paula project in Guerrero are the most relevant, with a striking 147 m of 4.13 gpt Au interval. Heliostar is trying to define a high-grade resource for underground mining, with the current results coming from a “Parallel Panel” to the High Grade Panel already defined. There are several mineralization stages at Ana Paula, as it often happens on large deposits, but the bulk of the high grade mineralization is related to a complex breccia “characterized by veins, fracture zones, and massive sulphide contact replacements”, according to Heliostar.
Prime Mining’s Los Reyes in Sinaloa is a strongly structurally controlled low sulfidation epithermal system characterized by veins and stockworks, whereas Radius Gold’s Tropico project in Zacatecas is a shallow low sulfidation epithermal system on which the shape and structural controls are still being defined.
