Outcrop Silver Makes a Discovery at Los Mangos, Stepping Out Four Kilometres South

Exploration Programs

OUTCROP SILVER MAKES A DISCOVERY AT

LOS MANGOS, STEPPING OUT FOUR

KILOMETRES SOUTH

VANCOUVER, BC

March 12, 2025

/CNW/ -

Outcrop Silver & Gold Corporation

(TSXV: OCG)

(OTCQX: OCGSF) (DE: MRG)

("Outcrop Silver")

is pleased to announce the discovery of high-

grade mineralization through drilling at its 100% owned Santa Ana high-grade silver project in

Colombia

, after following the company's strategy of making large step-outs to the south, along the

17 kilometre fully permitted vein system corridor. This discovery reinforces the path for scalability

and high-grade potential of the Santa Ana project as the drilling continues at this highly prospective

target.

Drilling Highlights

Hole DH444 intercepted 1.92 metres grading 586 grams per tonne of silver equivalent,

making a high-grade discovery at the Mangos SE vein (Table 1).

Hole DH442 intercepted 2.36 metres grading 404 grams per tonne of silver equivalent at

Los Mangos vein (Table 1).

The discovery at Los Mangos confirms the success of Outcrop Silver's exploration

strategy by making large step-outs along the 17-kilometre fully permitted mineralized

corridor. Los Mangos is 8 kilometres south of the resource and 4 kilometres south of

the recent La Ye discovery.

"The results from Los Mangos are a major breakthrough for the Santa Ana project, confirming high-

grade silver-gold mineralization in yet another significant step-out. Hitting strong grades more than 8

kilometers south of the closest resource vein proves the great potential of this system and validates

our exploration strategy," comments

Guillermo Hernandez

, Vice President of Exploration. "With

intercepts like 2.36 meters at 404 g/t AgEq, we are seeing wider mineralized veins that reinforce the

strength of the vein system. This discovery not only extends our high-grade footprint but also unlocks

new opportunities for further expansion in the underexplored central and southern portions of Santa

Ana."

The Los Mangos is a high-grade silver-gold vein system located in the central portion of the Santa

Ana project (Figure 1). The vein has a confirmed strike length exceeding 350 meters, highlighting its

potential for further expansion. It trends 40° and 60° dipping 60° to 80° to the southeast, with

localized northwest-dipping structures (Figure 1 and Figure 2). The main mineralized zone ranges up

to 1.20 meters in width, with strong argillic and sericitic alteration in the surrounding wall rock,

particularly evident in the historic El 20 underground workings (Figure 3). The vein is hosted within

green schists and granodioritic to dioritic dikes, indicating that mineralization is strongly influenced by

both structural and lithological controls.

metres. (CNW Group/Outcrop Silver & Gold Corporation)

The Los Mangos drilling campaign continues to validate the high-grade silver-gold potential in the

central portion of the Santa Ana project while also confirming the presence of wider mineralized

zones. Notably, hole DH442 intercepted 2.36 meters at 404 g/t AgEq in Los Mangos vein and 1.97

meters at 184 g/t AgEq in the Mangos SE sector. These broader vein widths align with

observations from the historic El 20 underground workings, reinforcing the presence of a robust and

continuous vein system.

Los Mangos has emerged as a key target for future resource expansion within the Santa Ana

project with strong silver-equivalent grades, strike continuity, and geological evidence of structural

complexity. Continued exploration will focus on extending known mineralization along strike and

testing depth potential further to define the system's scale.

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

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.
