Outcrop Silver & Gold Corporation (TSXV: OCG, OTCQX: OCGSF, DE: MRG) is pushing further into the northern reaches of its Los Mangos vein, part of the Santa Ana silver project in Colombia. For anyone closely following high-grade silver exploration in Latin America, these latest drill results are providing fresh optimism and a clearer picture of what could become a standout mineral asset.
Recent drilling at Los Mangos, specifically from hole DH476, has intercepted veins containing 445 grams per tonne of silver and 2.14 grams per tonne gold over 2.11 metres, as well as an interval with 507 grams per tonne of silver spanning 1.88 metres. One particularly high-grade subsection within these intervals returned an impressive 1,663 grams per tonne silver over just 0.40 metres. These findings are not just numbers, they’re firm evidence of both continuity and depth in the mineralized system, validating the company’s ongoing step-out drilling campaign in untested territory.
What’s especially intriguing for geologists and investors alike is the context of these intercepts. The northern extension of Los Mangos, where these results originated, exhibits a more complex structural setting. Here, high-grade silver-gold values are closely associated with granodioritic intrusions, geological features known to often enhance mineralization. The system remains open both along strike and at greater depths, meaning the exploration potential hasn’t yet reached its limits. Current drilling has confirmed continuity of the vein to depths approaching 150 metres below the surface, these are the deepest intercepts Outcrop Silver has drilled at Los Mangos so far.
Guillermo Hernandez, Vice President of Exploration, describes this sector as evolving quickly into a highly promising mineralized zone. Increased structural complexity isn’t a problem for this team, but an opportunity. The geological controls at play, like the intersection of granodiorite and local faulting, help concentrate the highest grades of precious metals. For Outcrop Silver, this means both greater confidence in the resource’s size and quality, and a stronger case for further investment in advanced exploration.
Another facet of this project is the robust quality assurance and analytical rigor applied to every drill core and surface sample. Outcrop Silver runs material through accredited, third-party labs, Actlabs in MedellÃn, Colombia, and Ancaster, Ontario, using both fire assay and instrumental analysis for gold, silver, and key base metals. Routine use of blanks, duplicates, and reference standards ensures assay results hold up to scrutiny, and results indicate no significant QA/QC problems to date.
It’s worth noting that the Santa Ana district, where Los Mangos sits, isn’t a newcomer to high-grade silver. The area boasts a mining history stretching back to the 16th century, and Outcrop Silver’s property now covers more than 28,000 hectares of this fertile ground. The project’s current mineral resource, as of a June 2023 technical report, included over 24 million ounces of indicated silver equivalent and another 13.5 million ounces inferred, at grades of 614 and 435 grams per tonne silver equivalent, respectively. These resources are hosted within a network spanning seven key vein systems, making Santa Ana the largest and reportedly highest-grade primary silver district in Colombia.
Looking ahead, Outcrop Silver’s roadmap is clear: keep expanding the mineralized footprint at Santa Ana, chase new targets along the project’s extensive 30-kilometre trend, and progress toward updated resource estimates. Their exploration team’s increasing focus on the emerging northern shoot at Los Mangos appears to be paying off, both in terms of geology and in growing interest from the mining community.
Underpinning all this is the company’s stated commitment to responsible mining and community engagement. Outcrop Silver’s team, with decades of Colombian experience, is working to ensure not only that mineral resources are maximized, but also that environmental and social standards remain front and center.
While there’s no guarantee in exploration, the trajectory at Santa Ana is strengthening. Every new batch of drill results helps connect the dots, between outcropping veins, underground potential, and the prospect of meaningful silver production. For Outcrop Silver, persistence and technical expertise are making the Santa Ana district look brighter with each passing season.
