Orosur Mining Inc. announced an update on the progress of the drilling campaign underway at the Company's Anzá project in Colombia. The Anzá project is currently the subject of an Exploration Agreement with Venture Option (Exploration Agreement) with Colombian company Minera Monte Águila (MMA). MMA is itself a 50/50 JV between Newmont Corporation and Agnico Eagle Mines Limited, and is the Colombian vehicle by which these two companies jointly exercise their rights and obligations with respect to the Exploration Agreement over the Anzá Project. MMA is the operator of the Anzá Project after exercising its right to assume operational control in the second half of 2021. Drilling recommenced at Anzá in October 2020, and since that time, 35 holes (MAP-072 to MAP-105) have been drilled at the central APTA project for a total of 15,195 metres. Following completion of hole MAP-105, that rig has now been mobilised to the NE of the project area and has commenced work at the Pepas prospect. Preparations for drilling at Pepas had been underway for some time, with all necessary permitting processes having commenced some months ago. The area is rugged and has required a substantial degree of preparation for access including a minor degree of helicopter support to move the rig into the vicinity of the Pepas target, after which it can then be moved by hand. In addition to this move to Pepas, two more rigs are currently in the process of being imported into Colombia to drill at APTA and the northern prospects of Pepas and Pupino. It is hoped they will be on site in several weeks. These rigs are man portable as is the current rig, but with more power and a different configuration that allows them to drill to depths in excess of 1,200 metres. The current and previous rigs used at APTA were constrained to depths of roughly 800 metres. As announced on March 8th, 2022, recent drilling at APTA had demonstrated substantial depth extents to mineralisation, well beyond what had been previously understood. MMA has thus decided to bring in new rigs capable of exploring these depth extents more efficiently.
