Latest drill results from APTA:MAP109 - 15.35m @ 0.97g/t Au, MAP110 - 43.55m @ 1.53g/t Au, including14.2m @ 3.1g/t Au APTA transitioning to resource drill out program. Pepas focus shifting to South Pepas targets following completion of land access agreements. Redrilling of restarted first hole at El Cedro, (CED001A) progressing well with core recovery having begun from 200m. New drill targets being developed at El Yarumo - examining Marmato analogue. After consultation on PTO, Pepas will move to PEA stage. London, United Kingdom--(Newsfile Corp. - November 4, 2026) - Orosur Mining Inc. announces an update on the progress of exploration activities at the Company's exploration project at Anzá in Colombia, at which three drill rigs are currently operating. Orosur CEO Brad George commented: "Work at Anzá has ramped up in recent times, accelerating on multiple fronts. With a new government and mining administration in place in Colombia, and with a solid balance sheet, we feel confident we can advance development at Pepas while in parallel moving APTA to resource and exploring the exciting Cedro/Yarumo cluster." Anzá - Colombia The Anzá Project in Colombia comprises a number of granted exploration titles and applications totalling roughly 530km2, within the Mid-Cauca copper/gold belt, west of Medellín. These titles and applications are 100% owned by two Colombian companies, Minera Anzá, and Minera Monte Aguila, both wholly owned subsidiaries of the Company. Since acquiring 100% control of the Project in late 2024, the Company has focussed its attention on three prospects: Pepas - a shallow, high-grade gold deposit for which the Company has calculated a Mineral Resource Estimate, announced February 10th 2026. APTA - a high-grade body of gold mineralisation that has seen over 40,000m of drilling since 2012. El Cedro/El Yarumo - a cluster of gold/copper porphyry intrusions and associated flanking hydrothermal systems in the south of the Project area at which drilling is underway. Figure 1.
