Pinnacle Discovers Silver-Lead-Zinc Mineralization Following up on LiDAR Survey at El Potrero
Pinnacle uncovers new polymetallic district potential at El Potrero while racing toward a 2026 production decision.

The most recent news (March 17, 2026) announces a new silver-lead-zinc (Ag-Pb-Zn) discovery on the southern Maria Fernanda 2 (MF2) block of the El Potrero project in Durango, Mexico. This discovery followed a LiDAR survey and initial prospecting, yielding assays up to 266 g/t Ag, 4.39% Pb, and 2.89% Zn. The veins trend northeasterly over at least 650 metres and are interpreted as a potential extension of the nearby Topia Mine district. This follows a February 26, 2026, update stating the company is advancing toward a production decision, with underground rehabilitation starting and metallurgical testing showing high gold/silver recoveries (7.7 g/t Au and 116 g/t Ag).
The news is Material - Positive for several reasons: - District Expansion: The discovery of a new mineralized style (polymetallic Ag-Pb-Zn) on a previously unexplored block (MF2) significantly increases the project's footprint and suggests El Potrero is part of a larger regional system (Topia District). - De-risking Production: The February news confirmed a signed community agreement with Ejido El Carmen and the commencement of underground rehabilitation. These are critical hurdles for any junior developer moving toward production. - Financial Flexibility: The February 23 amendment to delay US$750,000 in property payments into three tranches preserves immediate cash for the upcoming underground drilling program, reducing the immediate need for highly dilutive equity financing at low prices. - Validation of Technology: The success of the LiDAR survey in identifying these new veins validates management’s technical approach and suggests further "hidden" targets may exist under the rhyolitic cover.
Pinnacle Silver and Gold Corp. is focused on the El Potrero Project in Durango, Mexico. The project features a high-grade low-sulphidation epithermal system with three historic mines (Pinos Cuates, Dos de Mayo, La Dura) along a 1.6km trend. - Flagship: El Potrero (11 km²). - Infrastructure: Includes a 100 tpd plant (needs refurbishment), existing underground workings, and proximity (3km) to a power line. - Ownership: Pinnacle can earn a 50% interest upon commencing production, with a path to 100% ownership subject to a 2% NSR.
