Pinnacle Samples up to 17.7 g/t Gold on La Estrella Vein and Extends Strike Length of La Dura Vein, Enlarging the Footprint of the Gold-Silver System at El Potrero
Surface Wins Validate District Scale Potential at El Potrero Ahead of Maiden Drill Program
On January 20, 2026, Pinnacle Silver and Gold Corp. reported results from surface and underground channel sampling at the El Potrero project in Durango, Mexico. - La Estrella Vein: Sampling returned 12 metres grading 5.49 g/t Au (gold) and 48 g/t Ag (silver), and a separate interval of 22.5 metres grading 1.87 g/t Au and 51 g/t Ag. This vein is located approximately 500 metres southwest of the main Dos de Mayo structure. - La Dura Vein: Surface sampling extended the known strike length by 45 metres, returning 6.89 g/t Au and 208 g/t Ag. - The company states these results enlarge the footprint of the mineralized system both laterally and vertically. - CEO Robert Archer highlighted that finding high-grade mineralization 500m from the principal mines opens up the system size significantly.
This news is Positive but technically Routine in the context of an exploration company. - Proof of Concept: The identification of high-grade mineralization at La Estrella (500m offset from the main zone) validates the geological model that El Potrero is a district-scale system, not just a single historic mine. This de-risks the exploration thesis slightly by providing new targets outside the primary zone. - Sampling vs. Drilling: Investors should exercise caution. These are channel samples, which, while more representative than grab samples, are taken from exposed rock and can be subject to surface enrichment. They represent "smoke" rather than the "fire" of a drill intercept. - Preparation for Catalyst: This work effectively generates targets for the upcoming drill program. It does not immediately add resource ounces but justifies the expenditure for the drill bit. - Market Reaction: The stock held firm at $0.16 following the news, suggesting the market views this as a solid, if expected, step in systematic exploration.
- Company: Pinnacle Silver and Gold Corp. (TSXV: PINN) is an exploration company focused on Mexico.
- Flagship Project: El Potrero Project (Durango, Mexico).
- Asset: A low-sulphidation epithermal gold-silver system hosting three historic mines (Dos de Mayo, Pinos Cuates, La Dura).
- Infrastructure: Includes a 100 tpd processing plant (needs refurbishment) and existing underground workings.
- Status: Historically produced small-scale high-grade ore. Pinnacle is the first to apply modern systematic exploration and drilling. The project has a 1.6km confirmed strike length.
- Objective: To define a resource through underground and surface drilling and explore near-term production potential via the existing mill.
