Cordoba Minerals Corp has announced the recommencement of drilling at the high-grade, near-surface Alacran Deposit, in Colombia.
The Company is in the process of mobilizing one drill rig to the deposit, which is based within the copper-gold San Matias project. Along with a second contemplated in the coming weeks. The first 3 000 m of drilling are planned to test three high-priority targets, which include the new southern strike extension just east of the northern intrusive mineralization, and the down-dip extension on the western side of the deposit.
As reported in Cordoba’s July news release, drilling encountered high-grade copper-gold mineralisation outside of the current mineral resource area, which indicates the potential the project area has in terms of resource, perhaps this deposit will expand the current resource estimate. Drill hole ACD066 indicated that previous drilling in the southern-most part of the property was collared too far west and that the copper-gold deposit is offset to the east by post-mineralization faulting, indicating potential for undrilled strike extensions of almost 500 metres.
San Matias comprises a 20,000-hectare land package, with several known areas of porphyry copper-gold mineralisation, copper-gold mineralisation and vein-hosted, gold-copper mineralisation. The Alacran copper-gold system has a geographic location that makes it optimal for open-pit mining. Access and infrastructure are considered favourable by Cordoba.
Estimates as to the level of resources at Alacran make it even more favourable, with suggestions of 53.5 mil/t of 0.70% copper and 0.37 g/t gold in the deposit. Alacran is approximately 2 km southwest of the Company’s Montiel porphyry copper-gold discovery, where drilling intersected 101 m of 1.0% copper and 0.65 g/t gold, and 2 km northwest of the Costa Azul porphyry copper-gold discovery, where drilling intersected 87 m of 0.62% copper and 0.51 g/t gold.
The Alacran initial Inferred Mineral Resource estimate was completed by Mining Associates Limited and reported by the Company on 5 January 2017, and is in accordance with the Canadian Institute of Mining (CIM) definition standards.
