[{"type":"text","content":"Cordoba Minerals Identifies New Porphyry Copper Target Immediately West of the Alacran DepositIntrusive Breccias Point to Mineralized Porphyry Source of the Alacran Copper-Gold Deposit; Exploration Drill Program PlannedToronto, Ontario--(Newsfile Corp. - October 30, 2018) - Cordoba Minerals Corp. (TSXV: CDB) (OTCQX: CDBMF) (\"Cordoba\" or the \"Company\") today provides an update on recent exploration activities at its Alacran Deposit, located within the 100%-owned San Matias Copper-Gold Project in Colombia. A detailed investigation into the source of Alacran mineralization has led to the identification of a potential porphyry copper-gold source located immediately west of the Alacran Deposit. Drill targets are being finalized ahead of a planned 1,500 metre diamond drill program.HighlightsTwo distinct styles of mineralization have been identified at Alacran: 1. Replacement (or manto) copper-gold mineralization accounting for the bulk of the Alacran Deposit's Mineral Resources (Indicated: 36.1 million tonnes grading 0.57% copper and 0.26 g/t gold - Inferred: 31.8 million tonnes grading 0.52% copper and 0.24 g/t gold - refer to Cordoba's February 26, 2018 news release); and 2. Carbonate-base metal (\"CBM\") feeder zones. New evidence from surface mapping and drill hole re-logging suggests that both mineralization types are truncated to the west by late-mineral intrusive breccias.Two distinct types of intrusive breccia have been identified: andesitic and dacitic composition. Both are interpreted to have been emplaced along the same structures that earlier introduced the Alacran mineralizing fluids. While both breccia types contain rock fragments with replacement and CBM styles of mineralization, the dacitic breccia also contains clasts of porphyry-style mineralization with potassic alteration, which may be an indication of a nearby source of porphyry copper-gold mineralization. \"We are very pleased by the considerable progress being made at our Alacran Deposit,\" commented Mario Stifano, President and CEO of Cordoba Minerals. \"Through new surface mapping and by re-studying historical diamond drill core, our geological team has identified clasts of porphyry-style mineralization contained within intrusive breccias. We are in the process of finalizing drill targets and expect to commence diamond drilling in the coming week...
