El Santo : discovery of a new important polymetallic intersection

Auplata (Euronext Growth – FR0010397760 – ALAUP). As announced in the last press releases, Brexia Gold Plata Peru (BGPP) has launched the expansion of the exploration program at the El Santo mine. This program has been working on some mineralized layers, most of which will be subjected to a resource's certification in the coming weeks. Indeed, a new drilling in the southeastern part has uncovered a significant new intersection of a mineralized sedimentary rock with a much higher potential than was previously exploited. Once this discovery confirmed, El Santo resources will greatly expand.

Significant new polymetallic intersections at South-East El Santo Mine, Lima confirm mineralization over ~160m

This perforation was made with two objectives:

  • Drilling a potential at depth to intersected the Angel vein
  • Strategic drilling at depth to intersected sediment hosted replacement

This lithological drilling begins with Volcanic Rocks (porphyritic Andesite, Breccia Andesite and Volcanic Gaps) up to 72.45 meters and at elevation 4522.00 m.s.n.m (meter above sea level). Then Metamorphic Rock has been cut; Quartzite intersercted with Slate horizons up to 319.05 m at elevation 4311.00 m.s.n.m, following sedimentary rocks as Limestones, shales, bituminous limestones.

The carbonate intersection (Sedimentary hosted replacement fig. below) comes from 319.05 m to 485.20 m depths (166.15 meters thickness). There, we found wackestone and greenish limestone with shales intercalation. The mineralization is irregular with zonation, disseminated forms, and irregular veins containing sphalerite. Also, we encountered, galena, chalcopyrite, calcite, rhodonite, pyrite.

The mineralization is restricted to the fault line, sulfides veins such as Zinc. The lead is associated with presence of rhodonite, calcite and limestone that are favorable boxing rocks. In that respect, the mineralization lineament and possible contact angles vary between 35° to 45°. The alteration is moderate to intense and the carbonation is weak to moderate.

The cutting of the Angel vein itself has been at elevation 4185.00 m.s.n.m., from 462.90 m to 466.10 m with a thickness of 3.20 m at the roof of a strong fault.



These pictures are intended to be illustrative of ongoing activities at BGPP's El Santo Mine project. The results of these activities can only be quantified through assays results. Assay results will be made public by way of press releases once completed by technical teams at BGPP and its independent contractors.


416.70 m - 417.60 m (0.90 m) Limestone with shades of yellowish-green to cream with propylitic alteration intercalated with shale at an 35° angle. More than that, we encountered sporadic micro-veins of calcite and pyrite, that are weakly fracture, spread in traces, and with a 45° contact zone.

417.60 m - 418.40 m (0.80 m) Shale intercalation with shades of yellowish green; there is a propylitic alteration with 30° average. Also, there are pyrite spreads, Silification-Wackstone-Pervasive that are weakly to moderately fractured in sections.
