Outcrop Silver Continues to Extend Los Mangos Vein to the North
OUTCROP SILVER CONTINUES TO EXTEND
LOS MANGOS VEIN TO THE NORTH
VANCOUVER, BC
,
Aug. 7, 2025
/CNW/ -
Outcrop Silver & Gold Corporation
(TSXV: OCG)
(OTCQX: OCGSF) (DE: MRG)
("Outcrop Silver")
is pleased to report additional high-grade assay
results from step-out drilling at the Los Mangos vein within the Santa Ana high-grade silver project in
Colombia
. The results originate from the recently defined northern high-grade mineralized shoot,
situated approximately 150 metres north of the historical El 20 mine workings and the original
discovery zone (Figures 1 and 3). The Los Mangos vein remains open along strike and at depth
(Figure 3).
The latest intercepts continue to demonstrate the strong continuity and grade of the Los Mangos
vein system, particularly in its northern extension, where drilling has now reached the deepest
elevations to date in this sector.
Highlights
Hole DH476 intercepted 2.11 metres grading 445 g/t Ag and 2.14 g/t Au (606 g/t AgEq)
and 1.88 metres grading 507 g/t Ag (Table 1 and Figure 2).
These results reinforce the emerging importance of the northern shoot at Los Mangos, where the
vein system becomes structurally more complex and is hosted locally by granodioritic intrusions. The
association between these intrusions and high-grade mineralization suggests a strong structural and
lithological control on silver-gold deposition. Current drilling has now confirmed the continuity of the
Los Mangos vein to depths of nearly 150 metres below the surface in this area, marking the deepest
intercepts drilled at Los Mangos to date in terms of absolute elevation (Figure 3).
"The results from hole DH476, especially the multiple high-grade intercepts at depth, reinforce the
continuity and strength of the Los Mangos vein system. The northern shoot is evolving into an
exciting mineralized zone, and the increasing structural complexity, coupled with intrusive-related
controls, is opening new geological opportunities for deeper and lateral expansion," commented
Guillermo Hernandez
, Vice President of Exploration. "This continued success highlights the
exploration upside at Santa Ana and supports our strategy of unlocking value through step-out drilling
and advancing toward our next mineral resource update."

Figure 1. The plan view of the Los Mangos vein target shows the drill holes reported in this release
(Table 1), previously reported holes (Table 3), and surface exploration samples (Table 2).
Coordinates are in the UTM system, zone 18N, and WGS84 projection. Hole DH474 intercepted
2.11 m of quartz vein and breccias with No Significant Results in the Los Mangos vein, while hole
DH481 intercepted 1.33 m of quartz veining with No Significant Results. No Significant Result means
an intercept lower than 200 g/t AgEq1. (CNW Group/Outcrop Silver & Gold Corporation)

Qualified Person
The technical information contained in this news release has been reviewed and approved by Mr.

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:
Silver Equivalency Formula (CNW Group/Outcrop Silver & Gold Corporation)
QA/QC
Outcrop Silver applied its standard protocols for sampling and assay for exploration activities. 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
Canada in
Ancaster, Ontario
, 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 spans over 28,000 hectares within the Mariquita District,
encompassing both titles and applications, and is recognized 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 1,226 thousand tonnes containing 24.2 million ounces
silver equivalent
1
at a grade of 614 grams per tonne and an inferred resource of 966 thousand
tonnes containing 13.5 million ounces at a grade of 435 grams per tonne of silver equivalent
1
. 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. The current
exploration strategy seeks to establish a clear pathway for substantially expanding the mineral
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.
