Outcrop Silver & Gold extends Aguilar vein 450 metres at Santa Ana Project, Colombia
Outcrop Silver & Gold Corp. [TSX: OCG; OTCQX: OCGSF; DE: MRG] reported new drill results from its ongoing exploration program at the Santa Ana high-grade silver project in Colombia. Recent drilling has extended the Aguilar vein system by 450 metres to the south, confirming continuity beneath younger volcano sedimentary cover and identifying multiple high-grade intercepts in blind targets. These results significantly expand the known footprint of the vein system and support the potential emergence of a new high-grade shoot. Outcrop Silver continues to drill with three rigs along the fully permitted 17 km mineralized trend in preparation for its Q1 2026 mineral resource update.
Highlights: DH535 intercepted 0.84 metres grading 1,659 g/t AgEq. DH524 intercepted 1.04 metres grading 779 g/t AgEq.
Five drill holes (DH514, DH517, DH520, DH524, and DH528) represent a 450-metre step-out to the south, confirming the Aguilar vein continues beneath volcanic cover and remains open along strike and at depth.
Step-out drilling, demonstrated Outcrop Silver’s ability to identify high-grade silver mineralization in blind targets and reinforcing the potential that remains open along strike and at depth.
Results lay the groundwork for future drilling and reinforce the company’s expansion strategy ahead of its Q1 2026 Mineral Resource Update.
These new results, together with previously reported intercepts, confirm the Aguilar vein’s continuity in blind targets and significantly expand its known footprint. Importantly, drill holes DH514, DH517, DH520, DH524, and DH528 represent a step-out of 450 metres to the south from known mineralization and support the potential discovery of a new mineralized shoot. DH532 and DH535 are part of the resource definition program and demonstrate that the previously known high-grade shoot remains open along strike and at depth.
The Aguilar vein system continues to exhibit a complex structural architecture, with multiple splays, subparallel structures, and shallow, high-grade mineralization. These features suggest multi-phase mineralizing events and reinforce the interpretation of the system as a robust epithermal vein corridor.
“This latest round of drilling marks a major leap in our understanding of the Aguilar system,” commented Guillermo Hernandez, Vice President of Exploration. “The consistent intercepts in blind targets and the emergence of multiple high-grade centres add substantial value to our resource model. We now interpret at least three distinct mineralized shoots along Aguilar, which positions us well for continued resource expansion ahead of our Q1 2026 update.”
The Aguilar vein system represents one of the most significant and laterally extensive mineralized corridors within the Santa Ana project. Over time, exploration efforts have revealed that this corridor comprises multiple discrete but genetically related veins, most notably the Aguilar, Jimenez, and Guadual veins. These structures form a continuous mineralized trend that extends for more than 2 km along strike, with high-grade shoots defined across multiple segments, particularly in the Aguilar vein, where three distinctive shoots have been identified to date.
Recent step-out drilling to the south has added a new dimension to the geological understanding of the system. Drill holes have intercepted mineralized veins beneath a younger volcanosedimentary cover, confirming the presence of blind targets — areas where veins do not outcrop at the surface but remain mineralized at shallow to moderate depths.
Mineralization continues to display strong structural control, with veins hosted in competent wall rocks and demonstrating continuity along both strike and dip. Texturally and mineralogically, the Aguilar system is consistent with the broader Santa Ana district. The highest-grade intervals typically coincide with bands or breccia-clasts of pyrite and coarse-grained argentite, sometimes accompanied by electrum or sulfosalts. These associations reinforce the interpretation of the epithermal vein system characterized by strong metal zoning along strike and depth.
Outcrop Silver continues drilling with three rigs on-site, targeting further step-outs, resource definition, and testing of parallel structures across the 17-kilometre-long permitted mineralized corridor. The results at Aguilar underscore the company’s strategy of combining geological modeling, structural understanding, and phased drilling to drive both short-term and long-term mineral resource growth.
The 100% owned Santa Ana project spans over 28,000 hectares within the Mariquita District, encompassing both titles and applications, and is recognized as the largest and highest-grade primary silver district in Colombia, with mining records dating back to 1585.
Santa Ana’s maiden resource estimate, detailed in the NI 43-101 Technical Report titled “Santa Ana Property Mineral Resource Estimate,” dated June 8, 2023, prepared by AMC Mining Consultants, indicates an estimated indicated resource of 1,226,000 tonnes containing 24.2 million ounces silver equivalent at a grade of 614 g/t and an inferred resource of 966,000 tonnes containing 13.5 million ounces grading 435 g/t silver equivalent. The identified resources span seven major vein systems that include multiple parallel veins and mineralized shoots: Santa Ana (San Antonio, Roberto Tovar, San Juan shoots); La Porfia (La Ivana); El Dorado (El Dorado, La Abeja shoots); Paraiso (Megapozo); Las Maras; Los Naranjos, and La Isabela.
The drilling campaign aims to extend known mineralization and test new high-potential areas along the permitted section of the project’s extensive 30 km of mineralized trend. The current exploration strategy seeks to establish a clear pathway for substantially expanding the mineral resource. These efforts underscore the scalability of Santa Ana and its potential for substantial resource growth, positioning the project to develop into a high-grade, economically viable, and environmentally responsible silver mine.
