Orosur Mining Inc. has 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 with Colombian company Minera Monte Águila (MMA). MMA is itself a 50/50 JV between Newmont Corporation and Agnico Eagle Mines Ltd, 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 2H21.
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 m.
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 1200 m. The current and previous rigs used at APTA were constrained to depths of roughly 800 m. As announced on 8 March 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.
Pepas has been selected as the first new target for drilling not only because of extremely positive geochemical assay results as outlined in the 8 March 2022 announcement, but the prospect has also recently seen the completion of ground induced polarisation (IP) geophysical surveys.
IP surveys were trialled effectively at APTA in late 2021 but were halted due to difficulties in sourcing local labour during the coffee harvest. IP work recommenced in early 2022, starting in the northern extents and gradually being extended southward toward Pupino.
Details of this new drill program at Pepas will be released as the work progresses.
Samples from five holes (MAP-101 to MAP-105) are in the laboratory for assay. Results from these holes will be communicated to the market when they are available.
Orosur CEO, Brad George, commented: “It is exciting to be finally seeing drill rigs move into the wider region. Almost all drilling to date has been concentrated at APTA, and while this has at times returned spectacular results, it only represents about 5% of the strike length of the Aragon fault.”
