Pinnacle Silver and Gold Corp. Reports Discovery of Silver‑Lead‑Zinc Mineralization at El Potrero

Pinnacle Silver and Gold Corp. (TSXV: PINN) announced that follow‑up field work at the El Potrero project in Durango, Mexico, has confirmed the presence of previously unknown silver‑lead‑zinc (Ag‑Pb‑Zn) mineralization on the southern Maria Fernanda 2 claim block. The discovery was made during a mapping and prospecting program that built on results from an airborne LiDAR survey conducted in January 2026.

Background of the LiDAR Survey

The LiDAR survey covered the entire 1,074‑hectare project area and identified:

  • 6 shafts, 64 adits and 51 prospecting pits on the two claim blocks
  • Additional structural trends and previously unknown workings

Follow‑up field work began in early February on the MF2 block, where Pinnacle interpreted 3 shafts, 14 adits and 22 pits. Several outcrops of silicified breccia veins hosting silver‑lead‑zinc sulphides were observed and sampled.

Assay Results

Initial channel samples, up to 0.9 m in length, produced the following highlights:

Sample No.Width (m)Au (g/t)Ag (g/t)Pb %Zn %
EPPR260150.950.151260.551.51
EPPR260180.600.209310.722.58
EPPR260210.450.223331.642.89
EPPR260220.650.222410.411.24
EPPR260230.300.101712.392.04
EPPR260300.300.151260.551.51

The assays indicate up to 266 g/t of silver, 4.39 % lead and 2.89 % zinc in individual channel samples, with further results pending.

Significance of the Discovery

Pinnacle’s President & CEO, Robert Archer, noted that the combination of LiDAR technology, expert interpretation by GeoCloud Analytics, and on‑ground prospecting led to the discovery of a polymetallic zone not previously identified. The new mineralization is distinct from the northern El Potrero block, which contains only gold and silver.

This finding represents a new target area for Pinnacle on the El Potrero project and aligns with the polymetallic nature of the surrounding operating mines. The company plans further exploration to define the extent of the discovery.
