Key Takeaways:
Pinnacle Silver and Gold Corp. (TSXV: PINN, OTC: PSGCF, Frankfurt: P9J) announced new high-grade polymetallic discoveries at its El Potrero project in Mexico, with silver assays reaching up to 1,159 grams per tonne (g/t).
The results, announced on April 20, 2026, stem from ongoing ground prospecting of targets identified in a recent airborne LiDAR survey, the company said.
The silver-rich veins were found on the northern El Potrero claim block. Concurrently, fieldwork on the adjacent Maria Fernanda 2 concession extended the strike of previously identified silver-lead-zinc mineralization from March 2026.
These findings suggest the potential for a district-scale mineralized system at El Potrero, a significant development for the exploration-stage company. High-grade discoveries de-risk the project and can attract substantial investor interest ahead of a formal resource estimate.
The prospecting work on the northern part of the property uncovered silver-dominant veins that are consistent with the geological model of the area. The highlight assay of 1,159 g/t Ag provides a strong indication of the project's potential, significantly higher than many operating silver mines. For comparison, major primary silver mines often have average grades between 150 to 400 g/t.
On the MF2 concession, continued mapping and sampling have successfully extended the known Ag-Pb-Zn mineralization along strike, reinforcing the thesis of a large, continuous system. This builds on the company's previous announcements and demonstrates a growing footprint of mineralization.
The discoveries are part of a systematic exploration program following up on a high-resolution airborne LiDAR survey that identified numerous historical shafts, adits, and prospecting pits. By focusing on these previously un-documented workings, Pinnacle is effectively using modern technology to unlock the potential of a historic mining district.
