Pinnacle Silver & Gold - New Silver-Lead-Zinc Discovery at El Potrero

Mar 18, 2026
Bob Archer, President and CEO of Pinnacle Silver & Gold, discusses a LiDAR-driven discovery of high-grade silver-lead-zinc at El Potrero. He outlines links to the nearby Topia geology and how the find fits with fast-tracking gold-silver production. He also covers underground drilling plans, metallurgical testing, and infrastructure feasibility steps.

LiDAR Revealed New Polymetallic Veins

  • Pinnacle used high-resolution LiDAR to detect historical artisanal workings across previously unexplored parts of El Potrero.
  • Field teams then inspected shafts, adits and pits identified by LiDAR and returned assays showing high-grade silver-lead-zinc over at least a 650 meter strike.
ADVICE

Keep Production Pathway Separate From New Exploration

  • Continue fast-tracking the gold-silver zone to production while treating the new surface polymetallic discovery as an additional exploration priority.
  • Finish underground drilling and then pivot some resources to surface drill testing of the new silver-lead-zinc targets in a few months.

New Veins May Be Extension Of Topia System

  • The new mineralization is polymetallic (silver-lead-zinc) unlike the fast-track gold-silver zone, and resembles surrounding mines including Topia.
  • Topia lies ~4 km away and similar extensive lateral vein systems suggest the discovery could be its northeastern extension.
