Pinnacle Silver & Gold’s CEO Bob Archer joined the Vox Markets Podcast to explain how a lucky discovery during routine rehabilitation work at the El Potrero project in Mexico has filled in a critical gap in the company’s understanding of the mineralized system. While preparing for an underground drilling program, a contractor clearing known workings uncovered an opening that had been hidden by a small landslide. The team rehabilitated those workings too, took about 150 channel samples, and found that the new level sits roughly 35 meters above the main level and up-dip, connecting what was known underground with what had been sampled at surface. The result is a much clearer picture of continuity—and some eye-catching grades along the way.

  • 1 (00:59) **Introduction and Context** - Host Alistair introduces Pinnacle Silver & Gold and CEO Bob Archer for an update on the El Potrero project in Mexico.
  • 2 (01:28) **Discovery of New Underground Workings** - Bob describes how contractor rehabilitation work uncovered a previously unknown opening, leading to new sampling.
  • 3 (02:43) **Connecting the Mineralization Model** - The new data allowed the team to link the main underground level with surface mineralization, filling a critical gap.
  • 4 (03:54) **Bonanza Grades in New Samples** - Bob reports high-grade gold and silver results from the new workings, including up to 26 g/t gold and 511 g/t silver.
  • 5 (04:37) **Clarifying: Not Bigger, But Better Understood** - Bob corrects the assumption that the project is "bigger," explaining the discovery instead fills a knowledge gap.
  • 6 (05:52) **Resource Confidence Analogy** - Bob explains how filling data gaps moves a resource from inferred to indicated to measured, using a drilling analogy.
  • 7 (06:28) **Grade Variability and Consistency** - Bob discusses the variable nature of grades and why average grade and metallurgical consistency matter more for mining.

Show Notes

Pinnacle Silver & Gold has been delineating new zones of mineralisation at the El Potrero project in Mexico, after preparations for an ongoing underground drilling campaign uncovered new areas of the old mine that were previously unknown. Systematic sampling of these areas has shown continuity of mineralisation and added considerably to Pinnacle's confidence in the prospectivity and potential viability of the whole system. Drilling is ongoing, with the potential for a production decision by the end of the year. Chief executive Bob Archer joins Vox to tell us more
