VANCOUVER, BC, May 14, 2025 /CNW/ - Outcrop Silver & Gold Corporation (TSXV: OCG) (OTCQX: OCGSF) (DE: MRG) ("Outcrop Silver") is pleased to announce new drill results from the Los Mangos vein at its 100%-owned Santa Ana high-grade silver project in Colombia. The latest intercepts further confirm the presence of wide, high-grade zones within the system and reinforce the continuity of mineralization along strike and at depth (Figure 1 and Figure 2). These results follow the company's previously announced intercept of 18.30 metres at 992 g/t AgEq in hole DH459 (News Release dated May 6, 2025), and support the emerging significance of Los Mangos as one of the project's most robust vein systems discovered to date.
Highlights
Hole DH464 returned 3.86 metres at 621 g/t AgEq (433 g/t Ag and 2.51 g/t Au) (Table 1, Figure 3)
Recently announced high-grade drill results along strike at Los Mangos:
DH459: 18.30 metres at 992 g/t AgEq (News Release dated May 6, 2025)
DH457: 8.20 metres at 669 g/t AgEq (News Release dated April 22, 2025)
DH451: 7.18 metres at 358 g/t AgEq (News Release dated April 1, 2025)
DH444: 1.92 metres at 586 g/t AgEq (News Release dated March 12, 2025)
"Every new intercept at Los Mangos strengthens the case that the central portion of Santa Ana can add meaningful tonnes and grade in short order. These results validate our fully funded 24,000 metre drill program, which is laser focused on converting discoveries into ounces for the next resource update. We are executing exactly what we laid out to investors," stated Ian Harris, President & CEO. "This momentum is possible only through the hard work of our on site teams and the strong partnership we share with the people of Falan and Tolima—together carrying a 400 year silver legacy into the next generation."
The Los Mangos vein system lies in the southwestern portion of the fully permitted 17 kilometer mineralized corridor of the Santa Ana Project and is located more than 8 kilometres south of the current resource area (News Release April 26, 2023). Drilling has confirmed to date, a strike length of over 350 metres and vertical continuity exceeding 250 metres, with mineralization hosted in quartz-sulfide breccias and veins within altered green schists and intrusive dikes (Figure 3 and Figure 4).

"With each new hole, Los Mangos continues to prove itself as one of the most exciting discoveries within the Santa Ana project," commented Guillermo Hernandez, Vice President of Exploration. "These intercepts demonstrate not only the continuity of grade but also the persistence of thickness, which is critical for future resource expansions. Our targeting is becoming increasingly precise, and we remain confident that continued drilling will expand the high-grade footprint ahead of our upcoming resource update."

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
Outcrop Silver applied its standard protocols for sampling and assay for exploration activities. Underground channel samples were taken perpendicular to the vein and sample length was broken by geology. Core diameter is a mix of HTW and NTW depending on the depth of the drill hole. Diamond drill core boxes were photographed, sawed, sampled and tagged. Samples were bagged, tagged and packaged for shipment by truck from Santa Ana's core logging facilities in Falan, Colombia to the Actlabs certified sample preparation facility in Medellin, Colombia. ActLabs is an accredited laboratory independent of the Company. HQ-NTW core is sawn with one-half shipped. 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. 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 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.
