Outcrop Silver & Gold Corporation (TSX-V: OCG) (OTCQX: OCGSF) (DE: MRG) is pleased to announce new high-grade results from ongoing drilling at the Los Mangos vein, located in the central portion of the 100% owned Santa Ana high-grade silver project in Colombia. These results continue to demonstrate the strength and scale of the Los Mangos system, confirming both broad mineralized widths and continuity of high-grade silver-gold mineralization at depth and along strike.

The latest drilling campaign has returned exceptional results, highlighted by hole DH457 which intercepted 8.20 metres at 669 grams per tonne silver equivalent (Table 1). This represent one of the most robust intercepts to date from our target area, located over 8 kilometres south of the nearest defined resource. These results support Outcrop Silver’s strategy of expanding high-grade mineralization through significant step-outs along the fully permitted 17 kilometre mineralized vein corridor.

Highlights

• Hole DH457 intersected 8.20 metres grading 669 grams per tonne of silver equivalent in the Los Mangos vein (Table 1).
• This hole (DH457) intersected the junction of the Los Mangos and Mangos SE veins (Figure 2), confirming the potential for wider zones carrying high-grade mineralization.

“We couldn’t ask for a clearer signal of Santa Ana’s upside: 8.20 metres averaging 669 g/t AgEq—delivered from a hole drilled eight kilometres south of the existing resource. It’s a game‑changer that validates our district‑scale vision,” states Ian Harris, President and CEO. “We are uncovering one of the richest high‑grade silver projects globally, and this results hints at more to come. Our team has kept drills turning for twelve straight months, all feeding into a 2025 resource update designed to materially grow our silver inventory. We remain committed to advancing Santa Ana responsibly and to positioning Outcrop Silver as a premier name in the silver space.”

The Los Mangos vein is a high-grade silver-gold system located in the central portion of Outcrop Silver’s Santa Ana Project, approximately 8 kilometres south of the current resource. As one of  the most significant step-out discoveries since the 2023 maiden resource estimate (refer to News Release dated April 26, 2023), Los Mangos  has rapidly emerged as a key growth target within the company’s district-scale exploration strategy (refer to News Release dated March 18, 2024,).

Table 1. Drill hole assay results reported in this release.

Drilling at Los Mangos has defined a vein system corridor with a strike length exceeding 350 metres, with mineralization confirmed to depths beyond 200 metres. The vein trends between 40° to 60°, dips steeply (60°–80°), and is hosted within green schists and granodioritic to dioritic dikes. Strong argillic and sericitic alteration is closely associated with mineralization, particularly near the historic El 20 underground workings, which provide compelling evidence of the area’s long-standing high-grade potential (refer to  News Release dated November 12, 2024). In addition to drilling, surface sampling has returned assays up to 3,061 g/t AgEq (Table 2), further reinforcing the high-grade nature of the system. The discovery and an ongoing delineation  of the Los Mangos vein system highlight the success of Outcrop Silver’s large-scale, data-driven exploration strategy and underscore the company’s objective of significantly expanding the Santa Ana mineral resource through continued systematic testing of its extensive, fully permitted 17-kilometre mineralized corridor.

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 activities Outcrop Silver applied its standard protocols for sampling and assay. 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.
