Orosur Mining (LSE:OMI) has announced a significant drilling result from the APTA prospect at its Anzá Project in Colombia, with hole MAP-106A intersecting 229.7 metres grading 0.88 grams per tonne gold. The intercept included several higher-grade sections, with grades reaching up to 7.07 grams per tonne gold. The result further confirms the presence of a large epithermal gold system and has prompted the company to refine its geological interpretation of the Aragon fault zone, where mineralisation appears to be hosted within silicified sedimentary and volcaniclastic rocks.
The latest drilling has highlighted multiple avenues for future growth at APTA. Orosur plans to continue expanding a deeper high-grade mineralised zone that has already been traced along more than one kilometre of strike length. The company also intends to evaluate the potential for previously unidentified shallow bulk-tonnage mineralisation concealed beneath transported cover and to further investigate a hanging-wall vein structure that may offer attractive development potential. Together, these opportunities significantly enhance the exploration potential of the APTA prospect and could contribute meaningfully to the broader resource base at the Anzá Project.
The findings strengthen the company’s exploration outlook by demonstrating both scale and geological complexity within the system. As drilling continues, management believes the evolving geological model could support additional discoveries and improve the long-term development prospects of the Anzá district.
