The company holds full ownership of the exploration rights for the Anza Project, located in the Medellín-western Meta gold mining belt.
Orosur Mining announced that assay results from three new drill holes at the Pepas area of its Anzá gold mine project in Colombia reveal significant gold grades. Notably, hole PEP066 intersected 112 meters of mineralization starting from the surface, grading an impressive 5.25 grams per tonne (g/t) of gold. The company holds full ownership of exploration rights for the Anzá Project, located within the western Meta-Caquetá gold belt near Medellín. These rights and applications are currently held by two Colombian entities—Minera Anzá and Minera Monte Aguila—both of which are wholly owned subsidiaries of Orosur Mining.
Minera Monte Aguila was acquired by Orosur in November 2024 from its previous joint venture partners, Newmont Mining and Agnico Eagle Mines. The project spans approximately 330 square kilometers and encompasses exploration areas such as Pepas, APTA, and El Cedro. The primary focus is on expanding the exploration scope, particularly at the Pepas mine, where recent assay results have revealed highly promising gold mineralization. The company is now working to develop an initial Mineral Resource Estimate (MRE) for Pepas.
Meanwhile, soil geochemical studies at El Cedral have revealed high-grade potential, and a second porphyry deposit has been identified as a promising target for future exploration, with drilling expected to begin in early 2026. Additionally, the area is slated for an airborne magnetic/radiometric survey. APTA is a high-quality gold-mineralized site, having already completed 38,000 meters of drilling to date. However, current geological knowledge of the site remains insufficient to estimate the Mineral Resource Estimate (MRE). The company plans to conduct additional drilling at APTA by the end of 2025, aiming to accelerate the process of achieving the MRE.
Meanwhile, a drilling rig has arrived at the company’s El Pantano project in Argentina, kicking off the initial drilling program. The El Pantano project is an early-stage gold and silver exploration initiative located in southern Argentina’s Santa Cruz Province. Situated within Santa Cruz’s resource-rich Deseado地块, the project spans approximately 550 square kilometers of contiguous licensed areas. It is situated roughly 45 kilometers from Anglo American Group’s Cerro Vanguardia mine and about 90 kilometers southeast of Newmont Mining Corporation’s large-scale Cerro Negro mine. As of now, Orosur Mining holds a 51% stake in the El Pantano project and has already fulfilled its commitment to invest US$1 million (CAD$1.4 million) in exploration by February 2025. Brad George, CEO of Orosur, commented: "With our recent financing completed, Orosur is now fully positioned to advance our exploration efforts. Our strategic approach—focused on targeted geological prospects, 100% ownership, and leveraging recently discovered high-grade mineralization—is already paying off, placing us in a strong competitive position in today’s booming gold market."
