OUTCROP SILVER CONFIRMS CONSISTENT HIGH-GRADE AND WIDER VEIN INTERCEPTS AT GUADUAL NORTH, INCLUDING 1.86 METRES AT 519 G/T SILVER EQUIVALENT

Jun 04 2025 12:30 BST

VANCOUVER, BC , June 4, 2025 /CNW/ - Outcrop Silver & Gold Corporation (TSXV: OCG) (OTCQX: OCGSF) (DE: MRG) ("Outcrop Silver") is pleased to announce additional high-grade silver-gold results from the Guadual target, located in the central corridor of its 100% owned Santa Ana high-grade silver project in Colombia. The latest drill holes confirm wider, consistent high-grade mineralization in the Guadual North vein, further supporting the potential of the vein system to contribute to a future mineral resource update. The current confirmed footprint of Guadual is more than 500 metres along strike and 250 metres deep. Outcrop Silver has drilled a total of 3,817 metres in 19 holes to date at Guadual, and plans to execute a short delineation drilling campaign to support the upcoming mineral resource update.

Highlights

Hole DH463 intercepted 1.86 metres at 519 g/t AgEq (444 g/t Ag and 1.00 g/t Au) in the Guadual North vein (Table 1).
Hole DH462 intercepted 0.64 metres at 2,124 g/t AgEq (1,825 g/t Ag and 3.99 g/t Au) in the Guadual vein (Table 1).
Holes DH455, DH456, DH458, and DH460 intercepted consistently high-grade silver and gold mineralization in the northern section of the recently discovered high-grade shoot at Guadual North, confirming continuity over a 150 metres step-out to the north (Figure 1).

These results validate Guadual North as a zone of consistent, wider vein potential with strong grades, extending over several hundred metres on strike with vertical continuity. Drill hole DH463, in particular, delivers both width and grade, both key factors for future resource modeling.

"We're seeing consistent results at Guadual North that demonstrate not only high grades but also wide vein thicknesses that are very encouraging at the current stage," commented Guillermo Hernandez, Vice President of Exploration. "Intercepts like 1.86 metres at 519 g/t AgEq and 1.77 metres at 293 g/t AgEq are particularly promising, as they represent mineralized widths with scale. The added bonus of a splay zone in DH460 returning 3,349 g/t AgEq opens new opportunities to grow the system laterally as well. Guadual is proving to be a key part of the central corridor's evolving high-grade system."

The Guadual vein, along with its parallel structure Guadual North, forms part of the central mineralized trend at Santa Ana and represents the northernmost extension of the continuous Aguilar–Jimenez–Guadual vein system (Figure 1 and Figure 4). Structurally, it trends northeast and is hosted in low-grade green schists. The vein system includes multiple parallel veins and splays (Figure 1), with recent drilling confirming both grade consistency and structural continuity over a strike length exceeding 550 metres and a vertical extent of over 250 metres (Figure 4). Importantly, the target remains open both along strike and at depth, offering significant potential for further expansion through ongoing exploration (Figure 4).

Aguilar–Jimenez–Guadual Vein System

The Aguilar, Jimenez, and Guadual veins form a continuous, structurally connected corridor known as the Aguilar–Jimenez-Guadual vein system, which now includes three confirmed high-grade mineralized shoots (Figure 4) and extends for more than 2 kilometres along strike. With strong vertical continuity between 200 and 250 metres, this mineralized corridor represents one of the most promising high-grade zones within the Santa Ana project. The presence of multiple shoots and parallel splays within each vein points to significant upside potential for expanding the mineral resource both laterally and at depth.

Table 2 presents selected drill intercepts from across the entire vein system, highlighting some of the highest silver-equivalent grades drilled in this sector to date. Several veins exhibit multi-metre intercepts with silver-equivalent grades in the multi-kilogram-per-tonne range, further reinforcing the district's strong potential for high-margin, underground resource growth

¹ Silver 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.
