Cordoba Minerals Corp. (TSX-V:CDB; OTCQX:CDBMF) is pleased to announce an updated Mineral Resource estimate for the Alacran Deposit, located within the 100%-owned San Matias copper-gold project in Colombia.
- The updated, conceptual pit-constrained, Mineral Resource for the Alacran Deposit includes 36.1 Mt of Indicated Resources grading 0.57% Cu and 0.26 g/t Au (0.72% copper equivalent; CuEq), and 31.8 Mt of Inferred Resources grading 0.52% Cu and 0.24 g/t Au (0.65% CuEq) at a 0.28% CuEq cut-off.
- Indicated Resources contain 454 Mlbs of Cu and 300,000 oz of Au, and Inferred Resources contain 365 Mlbs of Cu and 250,000 oz of Au.
- The Alacran Deposit is expected to have low capital intensity given the highly favourable 1.17:1 strip ratio of the conceptual pit-constrained resource. This is due to the geometry of the deposit and its location along a ridgeline.
- High-grade diamond drill intercepts associated with carbonate-base metal (CBM) veins, which have been identified over 600 metres of strike length, were excluded from the geological model, but the sample values were retained and capped in the resource calculation. Specific high-grade intercepts, such as 4,440 g/t Au, 10.25% Cu, 347 g/t Ag, and 24.70% Zn over 0.9 metres in ACD036 (previously reported January 23, 2017), have been capped at 1% Cu and 2 g/t Au in the updated resource estimate.
- Drilling will also target copper and gold mineralization to the south that was not included in the pit-constrained resource.
- The Alacran north-south structural corridor has been mapped over 3 kilometres south of Alacran with similar host stratigraphy and new copper mineralization identified.
