July 17,2024 – Outcrop Silver & Gold Corporation (TSXV:OCG, OTCQX:OCGSF, DE:MRG) (“Outcrop Silver”) is pleased to announce additional drill results at the Aguilar vein discovery located 5 kilometres south of the existing resource along the 30 kilometre vein corridor. These recent drill holes at Aguilar have confirmed the continuity of high-grade silver along dip and revealed a new parallel blind vein, Aguilar-HW, with the potential of discovering additional veins. Outcrop Silver has two active drill rigs on site, focusing on drill testing the extensive inventory of exploration targets to expand the current resource. One rig is currently at Aguilar testing extension along strike and depth, while the other has begun testing the Guadual target, located 1.8 kilometres north of the Aguilar vein system (Figure 1).
HIGHLIGHTS
- DH369 intercepted 6.52 metres of 828 grams per tonne of silver equivalent, including 0.63 metres at 6,943 grams per tonne of silver equivalent
- DH371 intercepted 1.11 metres of 969 grams per tonne of silver equivalent and 0.31 metres of 3,741 grams per tonne of silver equivalent confirming the extension of Aguilar North at depth
- DH364 intercepted 1.63 metres of 717 grams per tonne of silver equivalent
- DH363 intercepted 1.04 metres of 1,218 grams per tonne of silver equivalent in a new blind discover, Aguilar-HW
“After confirming the existence of high grade further south with our current drilling campaign, we are excited with the recent holes that suggest more blind veins can be discovered,” explains Guillermo Hernandez, VP of Exploration. “Aguilar is demonstrating a robust vein system with many parallel veins, including splays that carry encouraging results. These types of complex vein systems are showing great potential for our drill campaign.”
The current drill campaign on the Aguilar vein aims to test the continuity of high grades that were identified through Outcrop Silver’s regional target generation program (see news release from May 09, 2022 and January 03, 2023). This surface exploration program traced the Aguilar vein system along more than 550 metres; as part of the Aguilar-Guadual vein zone, which extends for 1.8 kilometres (Figure 1). Geological mapping suggests higher-grade mineralization occurs at flexures within the dominant northeast trend of the veins with outcrops confirming the existence of high grade along the 550 metre long exposure (Figure 1 and Table 2). These flexures are interpreted to represent structural intersections between northerly trending faults and northwest-trending lineaments, which are currently being drill-tested.
The initial drilling of the Aguilar vein tested the continuity at depth from outcrop channel samples (SUCH220301, SUCH220302, SUCH220303, and SUCH220301) with high-grade assays from the regional target generation program, such as 0.90 m @ 500 g/t AgEq (see news release from May 9, 2022), and 2.70 m @ 267 g/t AgEq (see news release from January 03, 2023). The Aguilar vein at depth has been confirmed through seven drill holes as a low-angle structure, generally dipping 55° to the West, and showing 5 to 10% total sulfide content with parallel secondary veins and splays (Figure 2).
- DH363 intercepted 1.04 metres of quartz vein that assayed 8.57 grams per tonne of gold and 574 grams per tonne of silver, named as Aguilar-HW (Figure 2 and Table 1), while the Aguilar vein was intercepted at 0.50 m of 4.20 grams per tonne of gold and 876 grams per tonne of silver.
- DH364 intercepted 1.63 metres of 1.88 grams per tonne of gold and 576 grams per tonne of silver from the Aguilar vein towards the south (Figure 3 and Table 1).
Follow-up drilling focused on testing the lateral continuity of high-grade mineralization using the known sampled outcrops along the 550 metres of Aguilar vein exposure returned high-grade intercepts.
- DH369 intercepted 6.52 metres of 828 grams per tonne of silver equivalent, including 0.63 metres of 21.38 grams per tonne of gold and 5,337 grams per tonne of silver (Table 1).
- DH371 intercepted 1.11 metres of 969 grams per tonne of silver equivalent, including 0.42 metres of 8.64 grams per tonne of gold and 1,847 grams per tonne of silver (Table 1).
Drilling at Aguilar has one hole with assays pending: DH373 (Figure 1 and Figure 2).

Silver Equivalent
Metal prices used for equivalent calculations were US$1,800/oz for gold, and US$25/oz for silver. The equivalency formula as follows:
Metallurgical recoveries based on Outcrop Silver’s Metallurgical test work are 97% for gold and 93% for silver (see NR from August 23, 2023).
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 are 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, 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 2024 drilling campaign aims to extend known mineralization and test new high-potential areas along the project’s extensive 30 kilometres of strike. 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.
