Orosur Advances Anzá and El Pantano Gold Exploration Programs

Orosur Mining Inc. said it has made notable progress at its Anzá and El Pantano gold exploration projects in Colombia, stepping up field activity and advancing preparatory work toward potential resource definition. The company reported that mapping, geophysical surveys and initial drill mobilization have expanded the footprint of priority targets at both properties.

At Anzá, systematic surface sampling and updated structural interpretation have helped refine drill targets along several mineralized trends. Orosur said recent geophysical lines clarified subsurface continuity in zones previously identified by trenching and artisanal workings, allowing the team to prioritize deeper, higher-potential corridors for follow-up drilling. Drill rigs have been mobilized to selected pads, with the company emphasizing safety and permit compliance as it scales activity.

El Pantano has also seen intensified activity, with reconnaissance mapping and soil sampling extending known anomalous corridors. Orosur reported that initial drill holes are aimed at testing both near-surface oxide mineralization and deeper sulfide-hosted targets, while geotechnical and environmental baseline studies continue to support longer-term development planning. Community engagement and permitting remain a focus as field programs expand.

Management characterized the recent advances as technical and logistical milestones rather than definitive resource updates. Assay results from early holes and follow-up sampling campaigns are pending and will determine the next phase of work, including potential resource modelling and an expanded drill program. Orosur said it expects assay turnaround times to be influenced by regional lab capacity and seasonal weather, and commits to reporting results as they are validated.

Analysts and investors will be watching assay releases and any subsequent updates to the exploration model, which could impact the company’s valuation metrics if significant grades or widths are confirmed. For now, the reported progress at Anzá and El Pantano represents a deliberate push from reconnaissance toward systematic evaluation, underpinned by geophysical refinement, targeted drilling and stakeholder engagement. Orosur reiterated its operational focus on safe, compliant exploration and indicated that further technical updates will be issued once analytical data are returned and interpreted.
