Outcrop Silver & Gold Corporation (TSX-V: OCG) (OTCQX: OCGSF) (DE: MRG) is pleased to provide an update on drilling assay results from the La Ye vein at its 100% owned Santa Ana high-grade silver project in Colombia. Recent drilling has confirmed a 450 metre strike extension of La Ye vein, with mineralization extending to 200 metres down-dip. These results reinforce the potential of the La Ye vein to make substantial contribution to growth of the mineral resource at Santa Ana. Located approximately four kilometres south of the existing mineral resource area, La Ye vein demonstrates high grade silver-gold mineralization in both high-grade zones and broader mineralized intervals. These characteristics underscore its scalability and strategic importance in driving the continued resource growth of the Santa Ana project.

Drilling Highlights

• Hole DH421 intercepted 2.41 metres grading 227 grams per tonne of silver equivalent in the La Ye North vein (Table 1).
• Hole DH429 intercepted 1.41 metres grading 457 grams per tonne of silver equivalent in the newly discovered Lupe vein (Table 1).
• Drilling at La Ye has extended the vein system by more than 450 metres along strike and 200 metres down-dip (Figure 1 and Figure 2).
• Multiple intercepts in veins such as La Ye SH, La Ye North, and the La Lupe splay confirm the continuity of mineralization along strike and at depth.
• Drilling in La Ye has revealed the potential for wider vein zones or splayouts demonstrated by the newly identified Lupe vein.

“The recent results from La Ye highlight its exceptional potential to contribute to mineral resource expansion and together with the discovery of the Lupe vein shows the scalability and continuity of the system,” comments Guillermo Hernandez, Vice President of Exploration. “These findings reinforce La Ye’s role as a cornerstone of our exploration efforts at the Santa Ana project. Its proximity to other major veins and expanding footprint underscores the district’s immense potential, positioning Santa Ana as a potential world-class primarily silver project with transformative resource growth opportunities.”

The La Ye vein is a high-grade silver-gold system within Outcrop Silver’s Santa Ana project, characterized by its confirmed strike length over 450 metres and mineralization extending to 200 metres down-dip (Figure 1 and Figure 2). The vein system trends at an azimuth of 225° in azimuth, dips 55° to the west, and is hosted in weakly altered green schists. Surface expressions of La Ye vein include mineralized quartz veins with drusy textures, moderate sulfide mineralization such as pyrite and argentite, and sheared vein zones observable in outcrop exposures.

Recent drilling includes hole DH421, which intercepted 2.41 metres at 227 g/t AgEq in the La Ye North vein, including a high-grade section of 0.33 metres at 12.07 g/t Au and 687 g/t Ag, and hole DH429, which returned 1.41 metres at 457 g/t AgEq, with 0.33 metres at 1,716 g/t AgEq in the newly discovered La Lupe vein (Table 1). Additionally, narrower mineralized intercepts at La Ye North vein include hole DH422 (0.60 metres at 323 g/t AgEq) and hole DH424 (0.31 metres at 531 g/t AgEq).

Surface sampling has returned exceptional grades, including up to 2,553 g/t AgEq (Table 2), highlighting its high-grade potential. The recent discovery of the sub-parallel Lupe vein and broader splays reinforces the geological complexity and scalability of the La Ye system, making it a key contributor to the future resource expansion strategy at Santa Ana. The system also hosts multiple parallel and concealed veins, similar to the nearby Aguilar vein system, further enhancing its resource potential.

Strategically located within a priority exploration corridor, parallel to the Aguilar vein, La Ye presents significant potential for the discovery of additional, yet undiscovered, vein systems (Figure 1). With consistent high-grade results and a systematic drilling approach, La Ye is rapidly emerging as an essential target within the Santa Ana project, contributing substantially to potential resource expansion and the project’s long-term development.

¹Silver equivalent

Metal prices used for equivalent calculations were US$1,800/oz for gold, and US$25/oz for silver. Metallurgical recoveries based on Outcrop Silver’s metallurgical test work are 97% for gold and 93% for silver (see news release dated August 23, 2023). The equivalency formula is as follows:

QA/QC

For exploration core drilling, Outcrop Silver applied its standard protocols for sampling and assay. HQ-NTW core is sawn with one-half shipped. Core samples were sent to either ALS, Actlabs or SGS in Medellin, Colombia, for preparation. Samples delivered to Actlabs were AA assayed on Au, Ag, Pb, and Zn at Medellin using 1A2Au, 1A3Au, Multi-elements AR (Ag Cu Pb Zn), and Code 8 methods. Then, samples were sent to Actlabs Mexico for ICP-multi-elemental analysis with code 1E3. After preparation, the samples sent to ALS Colombia were shipped to ALS Lima for assaying using Au-ICP21, Au-GRA21, ME-MS41, Ag-GRA21, Ag-AA46, Pb-AA46, and Zn-AA46 methods. In line with QA/QC best practices, blanks, duplicates, and certified reference materials are inserted at approximately three control samples every twenty samples into the sample stream, monitoring laboratory performance. A comparison of control samples and their standard deviations indicates acceptable accuracy of the assays and no detectible contamination. No material QA/QC issues have been identified with respect to sample collection, security and assaying. The samples are analyzed for gold and silver using a standard fire assay on a 30-gram sample with a gravimetric finish for over-limits. Multi-element geochemistry was determined by ICP-MS using either aqua regia or four acid digestions. Crush rejects, pulps, and the remaining core are stored in a secured facility at Santa Ana for future assay verification.

About Santa Ana

The 100% owned Santa Ana project covers 27,000 hectares within the Mariquita District, through titles and applications, known 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 24.2 million ounces silver equivalent at a grade of 614 grams per tonne and an inferred resource of 13.5 million ounces at a grade of 435 grams per tonne. The identified resources span seven major vein systems that include multiple parallel veins and ore 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 current drilling campaign aims to extend known mineralization and test new high-potential areas along the permitted section of the project’s extensive 30 kilometres of mineralized trend. This year’s exploration strategy aims to demonstrate a clear pathway to substantially expand the 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.
