Project Argentum marks the formal commencement towards development of the Santa Ana project and includes the Silver Research and Innovation Center. Argentum is not just a conventional mining operation: it is an integrated development platform that combines responsible silver production, applied research with Colombian universities and the training of local talent. For Outcrop Silver and its investors, the pilot plant is intended to provide a platform that could be scaled up to a medium-scale underground operation in a staged manner, subject to the results of an anticipated Preliminary Economic Assessment (“PEA”) and regulatory approvals.

In a recent interview, Rob Bugamman, CEO of Outcrop Silver, detailed the strategic evolution of the Santa Ana mining project in Colombia. The company is advancing from the exclusive exploration phase towards the consolidation of a profitable production model. Current management is prioritizing the completion of a Preliminary Economic Assessment (PEA) to base the corporate valuation on its Net Present Value (NPV) and free cash flow projections, offering certainty metrics to investors.

By minimizing the volume of material to process and maximizing the ore grade, we optimize capital and operational costs, which is fundamental for our planned Preliminary Economic Assessment (PEA). This selectivity strategy not only improves the project's economics but also de-risks future operations.

Updated Mineral Resource Estimate (MRE) for our flagship Santa Ana project in Colombia. we have achieved significant growth: * Indicated Resources: A 23.5% increase reaching 29.9 Moz AgEq (exceptional average grade of 519 g/t). * Inferred Resources: 106.3% growth reaching 27.9 Moz AgEq. This achievement demonstrates the exceptional work of our exploration team. Vein systems like Guadual and Aguilar have contributed substantial resources. With a dozen additional veins yet to be adequately evaluated, the future of Santa Ana is bright.

US. Secretary of State Marco Rubio and Colombian Foreign Minister Omar Bula signed a U.S.–Colombia critical minerals framework in Barranquilla on September 8, 2026. Under the agreement, both governments will leverage public and private backing—spanning financing, insurance, and regulatory support—to select and fund key mining and processing ventures over the next six months. $OCG.TO $OCGSF #Silver Outcrop Silver: Grade Within Reach

Predictive geology delivers high-grade success. Outcrop Silver's structural model has confirmed "Shoot 7" at the flagship Santa Ana Project, proving systematic ore shoot recurrence along strike and reinforcing Santa Ana's position as one of the highest-grade primary silver assets globally. Key Drilling Intercepts: • Santa Ana (Shoot 7): DH648 intersected 9.16 m grading 188 g/t AgEq (incl. 0.40 m @ 2,693 g/t AgEq), with splay structure DH652 returning 5,947 g/t AgEq. • Las Maras: DH637 intersected 2.86 m grading 2,214 g/t AgEq, confirming high-grade continuity at depth. Predictable geometry eliminates exploration risk and directly drives resource growth ahead of our anticipated Mineral Resource Estimate update in September 2026. High grade, high silver purity, and expanding scale position Outcrop Silver for significant market re-rating.

#ForoDelAgua2026 | Water connects us—and challenges us to build solutions together. Minerales Santa Ana participated in the 2026 Water Forum in Ibagué, where Environmental Coordinator Carlos Alberto Betancur Galvis joined the “Water that Transforms” panel to discuss water-use efficiency, participatory monitoring, ecosystem protection, and environmental education in Falan. Collaboration between institutions, technical experts, and local communities is essential to addressing environmental challenges and strengthening water stewardship in the territory. $OCG.V $OCGSF #Silver @OCG_SilverGold Outcrop Silver: Grade Within Reach.

“Silver is a strategic sector for Colombia’s economic development.” In a recent article published by @RevistaSemana, Colombian Vice President José Manuel Restrepo outlined support for the development of Colombia’s silver, copper, gold, and rare earth sectors, with a clear focus on formal and responsible mining. For companies advancing high-grade silver projects in Colombia, policy certainty and a stable regulatory framework remain essential pillars for long-term capital investment and sustainable resource growth.
