COLOMBIA —Outcrop Silver & Gold Corporation (OCGSF) has updated the mineral resource estimate for its flagship Santa Ana primary silver deposit located in Colombia. The revised evaluation defines Indicated resources of 29.9 million ounces of silver-equivalent at an average grade of 519 grams per tonne, containing 21.7 million ounces of silver and 104,000 ounces of gold. Additionally, Inferred resources expanded to 27.9 million ounces of silver-equivalent at 369 grams per tonne, comprising 20.1 million ounces of silver and 98,000 ounces of gold. The updated assessment incorporates 130,006 meters of diamond drilling across 646 holes and reflects a 23.5 percent increase in Indicated silver-equivalent ounces and a 106.3 percent surge in Inferred resources compared to the maiden 2023 estimate.
The substantial growth of high-grade precious metal inventories underscores the structural continuity and scale of the vein systems within the Santa Ana property. By applying updated classification parameters and mineable shape optimization, the latest resource modeling enhances confidence in the project's economic viability and technical feasibility. The deposit spans multiple high-grade vein structures across a 17-kilometer strike length, with significant mineralization remaining open for expansion at depth and along strike.
This development significantly impacts the South American mining sector and foreign investors targeting high-grade precious metals projects. Colombia continues to attract international capital aimed at diversifying mineral supply chains, particularly for silver, which serves dual roles as a monetary metal and a critical input in industrial clean-energy technologies. Successful resource expansion in the region reinforces investor confidence in Colombian exploration assets despite complex regulatory and operational environments.
For mining enterprises and market participants, the expansion highlights the efficacy of systematic diamond drilling in unlocking value from high-grade epithermal vein systems. Outcrop Silver & Gold Corporation (OCGSF) is a Canadian mineral exploration company focused on discovering and defining high-grade silver and gold deposits in Colombia. With twelve additional identified vein targets awaiting definition drilling, the company remains positioned to further scale its resource base, offering potential strategic interest for mid-tier and major producers seeking quality development-stage precious metals assets.
