VANCOUVER, BRITISH COLUMBIA — January 6, 2026 — Leads & Copy —
Pinnacle Silver and Gold Corp. has announced that an airborne LiDAR survey flown over the El Potrero gold-silver project in Durango, Mexico, has confirmed known structural trends, outlined previously unknown structures, and identified a total of 64 adits, 6 shafts and 51 prospecting pits on the two claim blocks. The LiDAR survey covered the entire 11 km2 property and was flown by Eagle Mapping Ltd. of Langley, British Columbia. Reprocessing and interpretation of the data was conducted by GeoCloud Analytics of Melbourne, Australia. The company is adding to its geological team to follow up on the new targets identified.
Robert Archer, Pinnacle’s President & CEO, stated that the LiDAR survey was highly successful in confirming the 1,600 metre known strike length of the Dos de Mayo vein system and has identified new structures, often with artisanal workings that may indicate the presence of vein material. Archer added that the number of historic shafts, adits and pits interpreted from the LiDAR survey underscores the prospectivity of the project and, to date, the company has focused only on the northernmost 10% of the property.
On the northern claim block, the majority of the 3 shafts, 50 adits and 29 pits clearly outline the known trace of the Dos de Mayo vein system and the exposures of the El Capulin and La Estrella veins. The LiDAR also indicates the potential for an extension to this system to the southeast, across the river valley, where it would be hosted in similar andesitic rocks. In addition, there appears to be a previously unknown northeast-southwest trend on the southeast side of the valley, also in andesites, while similar northeast-southwest trends are observed in the southwest section, presumably hosted by intrusive rocks according to government regional geology maps. This latter scenario could give rise to a different, intrusive-related, style of mineralization.
On the separate Maria Fernanda 2 claim block to the southwest, 3 shafts, 14 adits and 22 pits are scattered across the concession. Government maps indicate a northwest-southeast trending structure passing through the middle of the block, parallel to the Dos de Mayo system and to the regional structural trend. The LiDAR also indicates a number of smaller structures perpendicular to this trend. The road from Topia passes through the middle of the block and road cuts locally display intense argillic alteration and pervasive chloritization with minor pyrite that may be indicative of a buried hydrothermal system. Pinnacle’s geological team is planning a systematic and thorough evaluation of the area, commencing early in the New Year.
LiDAR, or Light Detection and Ranging, is a remote sensing technology that uses laser light to measure distances, with 15-30 cm scale accuracy, to underlying rock surfaces. In this way, it can map out features such as structures and lithological contacts that can be related to mineralization but may not be exposed at surface. The survey also included colour aerial photography with 10-15 cm resolution that will assist in surface exploration and planning of infrastructure upgrades.
El Potrero is located in the Sierra Madre Occidental of western Mexico and lies within 35 kilometres of four operating mines, including the 4,000 tonnes per day Ciénega Mine, the 1,000 tpd Tahuehueto Mine and the 250 tpd Topia Mine. High-grade gold-silver mineralization occurs in a low sulphidation epithermal breccia vein system hosted within andesites of the Lower Volcanic Series and has three historic mines along a 500 metre strike length. The property has been in private hands for almost 40 years and has never been systematically explored by modern methods, leaving significant exploration potential. A previously operational 100 tpd plant on site can be refurbished / rebuilt and historic underground mine workings rehabilitated at relatively low cost in order to achieve near-term production once permits are in place.
Pinnacle will earn an initial 50% interest immediately upon commencing production. The goal would then be to generate sufficient cash flow with which to further develop the project and increase the Company’s ownership to 100% subject to a 2% NSR. If successful, this approach would be less dilutive for shareholders than relying on the equity markets to finance the growth of the Company.
