Outcrop Silver & Gold extends high-grade at Santa Ana Project, Colombia

Outcrop Silver & Gold Corp. [TSXV: OCG; OTCQX: OCGSF; DE: MRG] reported new high-grade intercepts from the Guadual vein at its 100%-owned Santa Ana primary silver project in Colombia, including 2.35 metres of 3,092 g/t silver and 4.95 g/t gold (3,463 g/t silver equivalent AgEq). With three rigs now turning, drilling is focused on tightening and extending the emerging high-grade core at Guadual North for potential inclusion in the company’s next mineral resource (MRE) update targeted for early 2026, while continuing to grow the broader Santa Ana vein inventory.

Highlights: DH493 intercepted 2.35 metres of 3,093 g/t Ag and 4.95 g/t Au (3,463 g/t AgEq). DH495 intercepted 1.30 metres of 4,587 g/t Ag and 12.30 g/t Au (5,510 g/t AgEq). DH486 intercepted 2.76 metres of 880 g/t Ag and 1.67 g/t Au (1,006 g/t AgEq).

Multiple drill holes intersected high-grade mineralization, confirming strike and depth continuity in the Guadual North vein system, which remains open in all directions.

“The results from Guadual continue to exceed expectations. Recent drilling has returned record silver-equivalent grades and excellent widths, demonstrating a robust and strongly mineralized system. These results demonstrate potential for significant high-grade silver resource additions to our upcoming MRE,” commented Guillermo Hernandez, Vice President of Exploration. “We are especially excited to see the mineralization remain open along strike and at depth. The team is delivering outstanding results and looking forward to continuing the definition and expansion of this exciting target.”

Guadual is a prominent vein target in the central part of the Santa Ana project. Structurally aligned NNE-NE and dipping sub-vertically, the vein hosts quartz-sulfide mineralization associated with argentite, pyrite, and galena, typical of Santa Ana’s high-grade mineral systems. Surface trenching and prior drilling confirmed a footprint of more than 400 metres, with the Guadual North segment now emerging as a high-grade core area for near-term mineral resource inclusion.

The delineation drilling campaign at Guadual will continue with both step-out and infill drilling designed to define the full extent of the mineralized shoots identified to date, particularly in the Guadual North vein.

The current focus is on tightening drill spacing within high-grade zones to meet the requirements for resource estimation, while also extending drilling at depth and along strike to test the continuity of the mineralization. Concurrently, geological and structural modeling is being advanced to refine the interpretation of vein geometries, with grade shell modeling and domain definition already underway.

These efforts will feed directly into an internal mineral resource estimate calculations currently underway. Additionally, exploration drilling will assess the potential structural connections between the Guadual, Jimenez, and Aguilar veins, which together form a mineralized corridor exceeding 2 km in length with multiple confirmed high-grade shoots.

The outcomes of these steps are expected to provide a robust foundation for a significant expansion of the mineral resources at Santa Ana. 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 grading 614 g/t and an inferred resource of 966,000 tonnes containing 13.5 million ounces grading 435 g/t of 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.
