Almadex Minerals Ltd. reported the receipt of findings from the second hole (SP-22-004) drilled on its wholly owned San Pedro Project in Jalisco, Mexico, in 2022. Hole SP-22-003, which intersected 4.51 m of silver weighing 656.8 g/t, was drilled from the same pad as this one.

SP-22-003 was drilled with a −50° inclination, whereas SP-22-004 was drilled with a −75° inclination. SP-22-004 seems to have crossed an old mining excavation from 1.1 to 3.1 m deep, filled with broken rock, mud, and some wooden fragments.
Due to poor recovery before and after, just 1.3 meters (m) from 4.2 to 5.5 m depth was sampled, yielding 846.0 g/t silver. Drilling in this region of the property has intersected extended sections of brecciated and altered rock. The current drilling program is intended to improve understanding of the orientation and spread of the breccia zone so that more focused drilling can be carried out in the future.
The San Pedro project encompasses a broad area of acid sulfate alteration, including previously known vuggy silica zones. Recent Terraspec research shows sericitization on top of propylitic alteration in the mineralized zones, with acid sulfate alteration happening at the project’s northern end.
Outcrop samples and prior soil sampling surveys have yielded elevated base metals and silver. Prior RC drilling by earlier operators, including Cominco, yielded anomalous gold, silver, and base metals. Almadex has now successfully completed holes in this Phase 2 program, including the one disclosed here, in addition to the two done in 2021.
