September 11,2024 – Outcrop Silver & Gold Corporation (TSXV:OCG, OTCQX:OCGSF, DE:MRG) (“Outcrop Silver”) is pleased to provide an update on the 2024 exploration drilling program at its 100% owned Santa Ana high-grade primary silver project. The drilling compaign continues to deliver excellent results along the robust Aguilar vein system. Recently tested targets, Jimenez and Guadual, have confirmed the continuity of this vein system for 1.5 kilometres along strike, and 200 metres down-dip. Outcrop Silver is currently drilling with two rigs at the Aguilar vein system and plans to commence drilling at the promising Los Mangos and La Ye targets in the following months.
Drilling Highlights
- DH388 intercepted 1.3 metres, returning 888 grams per tonne silver equivalent at the Aguilar vein system (Table 1).
- Drill hole DH391 intercepted 0.30 metres with 3,043 grams per tonne silver confirming depth continuity of high-grade mineralization seen at surface on the Jimenez vein.
- Drilling to date at the Aguilar vein system has confirmed continuity through step-outs along 1.5 kilometers (see Figure 1), highlighting the potential for multiple mineralized shoots (Figure 2).
“We’re thrilled to be pushing further into the southern extensions of the Santa Ana vein system,” comments Guillermo Hernandez, Vice President of Exploration. “With each drill hole, we’re unlocking high-grade silver at depth, confirming our strategy and setting the stage for future resource growth. The results so far have been exceptional, consistently delivering high-grade intercepts and pointing us toward even richer mineral shoots. It’s an exciting time as we turn these targets into discoveries for future tangible mineral resources.”
Drilling along the Aguilar vein system, spanning three targets (Aguilar, Jimenez, and Guadual), has confirmed the lateral continuity of the entire vein system (Figure 1). By combining surface exploration data with underground information from old mine workings, Outcrop Silver has developed a longitudinal section of grade x thickness (Figure 2) to guide and refine follow-up drilling in this vein. Results to date indicate three distinct high-grade areas, which we believe represent mineral shoots with significant potential for resource expansion. The ongoing drilling campaign is focused on the northern section of the Aguilar target and the Jimenez area below the 700-meter elevation, aiming to confirm the presence of a mineral shoot. To date, twenty-one holes have been completed at Aguilar target, with results still pending for one drill hole. Furthermore, eight drill holes have been completed at Guadual zone and two at the Jimenez target, marking significant progress in the exploration efforts.

Jimenez and Guadual targets
The Jimenez vein has a confirmed strike length of 500 metres and is located in the central part of the Aguilar vein system (Figure 1). It is characterized by parallel and subparallel veins, with significant historical workings including adits from colonial times, characterize it. High-grade silver and gold mineralization has been reported through Outcrop Silver’s target generation program, with assay results of up to 2,903 g/t AgEq and 2,010 g/t AgEq (Table 2).
The Guadual vein is located in the northern part of the Aguilar vein system, with a confirmed strike length of 700 meters. Quartz veins and shear zones, bearing significant silver and gold values, are prominent features of the system (Figure 1). The vein structure is complex, showing multiple parallel and intersecting veins. Notable assays include up to 1,172 g/t silver and 7.78 g/t gold (Table 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 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.
