Northern Extension Drilling Delivers High-Grade Silver Results at Los Mangos

Outcrop Silver reports 445 g/t silver intercepts from Los Mangos northern extension drilling, located 150 metres north of historic workings.
- High-Grade Intercepts: Hole DH476 returned 2.11 metres grading 445 g/t silver and 2.14 g/t gold, equivalent to 606 g/t silver
- Structural Complexity: Northern shoot contains granodioritic intrusion-hosted mineralisation with increased structural complexity
- Depth Extension: Drilling reaches nearly 150 metres below surface, representing the deepest intercepts achieved at Los Mangos
- Resource Expansion: Northern extension located 150 metres north of historical El 20 mine workings opens new exploration opportunities
- Open Potential: Los Mangos vein system remains open along strike and at depth for further expansion
Outcrop Silver & Gold Corporation (TSXV:OCG, OTCQX:OCGSF, DE:MRG) is an explorer and developer focused on silver projects in Colombia. The company employs a team with regional experience to advance mineral resources through exploration programmes. The company's operations include responsible mining practices and community engagement as part of its development approach. Outcrop Silver operates in Colombia's geological and market environment, working to identify opportunities whilst maintaining environmental and community standards.
High-Grade Assays from Northern Extension
The drilling results from hole DH476 show grade continuity of the Los Mangos vein system in its northern extension. The intercept of 2.11 metres grading 445 g/t silver and 2.14 g/t gold represents a silver equivalent grade of 606 g/t, based on the company's reported equivalency formula. Additional intercepts from the same hole returned 1.88 metres grading 507 g/t silver.
These results indicate that the northern extension maintains similar grades to other areas of the Los Mangos system. The intercepts occur at the deepest elevations drilled to date in this northern sector. This represents a vertical extension of the known mineralised system.
The presence of multiple high-grade intervals within a single drill hole indicates mineralised zones in the northern extension. This pattern occurs along a vein system that remains open along strike and at depth according to the company's geological interpretation.
Emerging Northern Shoot with Structural Controls
The northern shoot at Los Mangos contains structural complexity, with mineralisation hosted locally by granodioritic intrusions. The company reports an association between intrusive rocks and high-grade mineralisation, suggesting structural and lithological controls on silver-gold deposition. These structural characteristics are noted by the company as relevant for exploration targeting.
Current drilling has extended the Los Mangos vein to depths of nearly 150 metres below surface in the northern area. This represents the deepest absolute elevation intercepts achieved at Los Mangos according to the company's drilling records. The granodioritic intrusive relationship provides geological information for future drilling programmes.
Vice President of Exploration Guillermo Hernandez stated that
"the increasing structural complexity, coupled with intrusive-related controls, is opening new geological opportunities for deeper and lateral expansion."
This structural information forms part of the company's geological database for designing future exploration programmes.
Exploration Implications for Resource Expansion
The northern extension results are located approximately 150 metres north of the historical El 20 mine workings and original discovery zone. The company reports that the Los Mangos vein system remains open along strike and at depth. The northern extension represents an area beyond current resource boundaries.
The current drilling campaign targets known mineralisation extension and tests areas along the project's 30 kilometres of mineralised trend. The company states this approach aims to expand the mineral resource estimate. The Los Mangos northern extension forms part of this broader exploration programme.
The results contribute to the company's preparation for a mineral resource update. The Santa Ana project's current maiden resource estimate contains 24.2 million ounces silver equivalent in the indicated category and 13.5 million ounces in the inferred category across seven major vein systems. The Los Mangos northern extension adds to the drill database for potential resource model updates.
Looking Forward
Outcrop Silver continues drilling at Los Mangos as part of its broader exploration programme. The northern extension results will be incorporated into future resource modelling work. The company has indicated plans for an updated resource estimate, though no timeline has been specified in this release.
Planned activities include continued step-out drilling to further define the northern shoot and testing similar structural targets across the Santa Ana project. The company's current approach involves systematic exploration programmes designed to add to the geological database and advance the project through development stages.
