Pinnacle Flies LiDAR Survey at El Potrero
None
Pinnacle Silver and Gold Corp. (PINN) announced on November 24, 2025, the completion of an airborne LiDAR (Light Detection and Ranging) survey over its entire 11 square kilometre El Potrero gold-silver project in Durango, Mexico. The survey was conducted by Eagle Mapping Ltd. with data processing by GeoCloud Analytics. The company expects to receive the final results by early to mid-December. The LiDAR technology is intended to aid in mapping geological structures, identifying mineralization features not visible at the surface, connecting the Dos de Mayo vein system along strike, and defining parallel and splay veins. It is also expected to detect subtle, potentially buried features such as old mine workings, pits, and trenches, which could lead to new discoveries and will be crucial for interpreting the geological environment and planning the upcoming surface drill program.
This news is a routine, positive step in the exploration workflow for Pinnacle Silver and Gold. The completion of a LiDAR survey is a standard and necessary component of modern exploration, particularly for defining structural controls and optimizing drill target identification in areas with limited outcrop exposure, as mentioned by CEO Robert Archer.
When evaluated against prior news, this development aligns perfectly with the company's stated plans. The March 18, 2025, and April 17, 2025, news releases indicated that a LiDAR survey was "planned" or "under preliminary discussions" to map subsurface rock, interpret structural features, and aid in drill program planning. The current announcement confirms the execution of this planned activity.
The material impact is positive in that it demonstrates consistent progress towards advancing the El Potrero project from initial sampling into a systematic exploration phase focused on drilling. However, it is not a "game-changer" on its own, as it is an expected technical step rather than a discovery or a significant financing event. The real impact will come with the results of the LiDAR survey in early to mid-December, which will inform the forthcoming surface drill program.
The company has been systematically de-risking the project by: 1. Acquisition and Due Diligence: Successfully acquired the El Potrero project (Feb 2025). 2. Initial Sampling: Reported high-grade gold-silver in preliminary and ongoing underground/surface sampling (March, June, July, September, November 2025). This confirmed the historic potential and identified new parallel veins (El Capulin) and extended strike lengths (La Dura, Dos de Mayo). 3. Metallurgical Testing: Showed excellent gold recoveries (Oct 2025), which is crucial for future economic viability. 4. Team Building: Appointed an experienced project manager in Mexico (Oct 2025). 5. Financing: Successfully completed two private placements (Feb, Aug 2025) to fund these activities.
The LiDAR survey is the next logical step in this progression, providing critical data for the highly anticipated drill program. The results, when released, will be more impactful as they will directly influence the precision and effectiveness of future drilling.
Pinnacle Silver and Gold Corp. is a Canadian exploration company focused on the El Potrero gold-silver project in Durango, Mexico. The company recently completed the staged acquisition of up to a 100% interest in El Potrero in February 2025, subject to a 2% Net Smelter Return (NSR) royalty.
Flagship Project: El Potrero Gold-Silver Project * Location: Durango, Mexico, within the prolific Sierra Madre Occidental. It is situated within 35 km of several operating mines (Cienega, Tahuehueto, Topia). * History: The property, covering 1,074 hectares across 8 concessions, hosts three historic mines (Pinos Cuates, Dos de Mayo, La Dura) along a 500-metre strike length. It was privately held for almost 40 years and was never systematically explored using modern methods or drilling. A small-scale operation with a 100 tpd plant (vat-leach cyanidation and Merrill Crowe circuit) operated from 1989-1990. * Mineralization: Characterized as a low-sulphidation epithermal breccia vein system hosted in andesites of the Lower Volcanic Series. A quartz-feldspar porphyry dike is identified as a critical exploration feature, potentially localizing gold-silver mineralization. Grades reported from historic workings and recent sampling are high-grade, with widths ranging from 0.5 to 10 metres. Mineralization is associated with grey-black bands of ginguro (fine-grained electrum and silver sulphides) and minor pyrite/iron oxides. * Historic Resource: A historical resource estimate of 45,561 tonnes at 8.0 g/t gold and 186 g/t silver (10.1 g/t AuEq or 890 g/t AgEq) exists, based on underground sampling of historic mines. Pinnacle notes this is historical and not classified as current mineral resources. * Infrastructure: The project benefits from existing infrastructure, including an operational 100 tpd plant (refurbishable/rebuildable at relatively low cost), historic underground mine workings that can be rehabilitated, existing road access, and a power line within three kilometres. Surface rights for the plant and mine area are privately owned, potentially easing permitting processes. * Development Plan: Pinnacle's strategy is to earn an initial 50% interest upon commencing production, with the goal of generating cash flow to fund further development and increase ownership to 100%. This approach is intended to be less dilutive for shareholders than relying on equity markets. * Recent Exploration: The company has conducted extensive surface and underground mapping and channel sampling, confirming high-grade gold-silver mineralization (e.g., 85.1 g/t Au and 520 g/t Ag over 0.5m at Pinos Cuates; 15.55 g/t Au and 222 g/t Ag over 1.1m at Dos de Mayo). They have also identified a new parallel vein system (El Capulin) and extended the known strike length of the Dos de Mayo system to 1.6 km. Preliminary metallurgical tests show excellent gold recoveries (avg. 95.09%). The recent LiDAR survey aims to further refine drill targets.
