Orosur Mining Inc. (TSXV:OMI,OTC:OROXF)(AIM:OMI) has announced an update on the progress of exploration activities at the Company’s exploration project at Anz\u00e1 in Colombia (“Anz\u00e1). The Anz\u00e1 Project comprises a number of granted exploration titles and applications totalling roughly 327km2 within the Mid-Cauca gold belt, west of the city of Medellin.<\/p>\n
These titles and applications are owned by two Colombian companies, Minera Anz\u00e1, and Minera Monte Aguila, both of which are wholly owned subsidiaries of the Company. The latter of these was acquired by Orosur in November 2024 from the Company’s previous JV partners, Newmont Mining and Agnico Eagle Mines. Orosur thus owns 100% of the Anz\u00e1 Project.<\/p>\n
As announced on 14th July 2025, the Company had taken the formal decision to commence infill drilling at its Pepas gold prospect at Anz\u00e1, with the objective of moving Pepas to a NI43-101 compliant Mineral Resource Estimate (“MRE”) as quickly as possible. This infill drill program was completed late in December 2025, with results from the final three holes PEP072, PEP073 and PEP074 just received.<\/p>\n
As expected, gold assay results from these three holes were exceptional, demonstrating the core of Pepas to contain very thick, high-grade zones of gold mineralisation. The results include:<\/p>\n
PEP072B – 47.60m @ 3.43g\/t Au from surface<\/strong><\/p>\n<\/li>\n PEP073 – 104.45m @ 5.96g\/t Au from surface<\/strong><\/p>\n<\/li>\n PEP074 – 71.35m @ 6.46g\/t Au from surface<\/strong><\/p>\n<\/li>\n<\/ul>\n With the receipt of these results, the gold assay database has been closed off and handed to our resource consultants so that work on the MRE modelling process can commence.<\/p>\n The Company has begun the process of assessing the economic exploitation options for Pepas in the context of the Colombian permitting regime. Discussions are currently underway with local technical consultants to map out the permitting framework, necessary environmental and social studies, and development of the required technical work plan (Programa de Trabajo y Obras – PTO), that could commence once an MRE is finalised.<\/p>\n Following the Christmas break and retirement of the old drill rig for much needed repairs, a new rig has arrived on site to commence a regional drill program north of Pepas. This program is reconnaissance in nature, designed to better understand the wider litho-structural environment that controls the Pepas mineralisation.<\/p>\n The Company is constantly assessing its land package in Colombia in terms of geological potential, costs to hold, the ability of exploration work to be undertaken and any subsequent discovery exploited in light of local community sentiment.<\/p>\n To that end, several major adjustments were made at the end of December 2025. Two of the larger, longer held applications, that made up the bulk of the original Anz\u00e1 JV project, have now been granted, and converted to exploration licences. The Company thus now has three large contiguous granted Titles, totalling 173km2, all within the mining friendly Anz\u00e1 municipality, an increase of some 65%.<\/p>\n Figure 1. Anz\u00e1 Project<\/strong><\/p>\n Orosur CEO Brad George commented: “The Company starts 2026 in a very different position to a year ago. One deposit (hopefully) soon to enter feasibility, two rigs turning in two countries and an increasing list of high-quality targets lining up to be next. Exciting times”.<\/p>\nFeasibility and Wider Exploration<\/h3>\n
