VANCOUVER, BRITISH COLUMBIA, Jul 20, 2010 (Marketwire via COMTEX) — Coro Mining Corp. (“Coro” or the “Company”) (TSX: COP | PowerRating) is pleased to announce that Quantec International Project Services Ltd. has completed a 6 line – km Titan 24 DCIP survey at Coro’s 100% owned Chacay porphyry copper property, located 12km southeast of the Teck Resources Limited’s Relincho copper-molybdenum project, and 50km east of the city of Vallenar in the III Region of Chile, at an elevation of approximately 2,600m above sea level.
Alan Stephens, President and CEO of Coro commented, “The Titan survey has defined significant chargeability anomalies extending to depths in excess of 500m, coincident with the Nacho, Lucho and Martin zones of alteration and mineralization, which are interpreted to reflect separate diorite porphyry intrusives. In addition, a roughly flat lying chargeability high and resistivity low anomaly, thought to represent increased pyrite content with associated chalcocite, coincides with the drilled enrichment blanket and extends beyond it. We are pleased with the results of the Titan survey which has significantly improved our knowledge of the mineralization at Chacay, and we intend to initiate a drilling program in the near future to further define these new targets.”
The Chacay property hosts a porphyry copper prospect of probable Eocene age that has previously been drill tested by several companies. The drillhole locations and summary geological information are available for some of the previous drilling but it has not been possible to obtain the corresponding assay information. A zoned porphyry alteration suite of external propylitic alteration surrounding a phyllically altered core is developed over a distance of 3,500m, oriented west northwest. Three zones of copper mineralization have been outlined by the drilling to date.
The largest of these, known as the Nacho Zone, occupies an area of approximately 900 x 850m centered on Cerro Colorado. This hill has an elevation difference of 300m over the surrounding valleys and hosts a leached cap, which drilling has shown to vary from 50 to 200m in thickness. Underlying the leached cap, a partially oxidized, flat lying, chalcocite enrichment blanket has been intersected in drilling, that is currently interpreted to be between 20m thick on its margins and greater than 100m thick towards its centre. The chalcocite blanket is thickest and has the highest copper grades when developed within a diorite porphyry intrusive exhibiting sericite-chlorite-quartz alteration, and which contained original primary copper sulphides. This diorite is emplaced into moderate to strongly quartz-sericite-pyrite altered dacite volcanics, which generally host secondary mineralization grading less than 0.2%CuT, with chalcocite occurring only as coatings on pyrite. A weakly altered, late mineral hornblende diorite occurs as small stocks and dykes within the Nacho Zone, as do post mineral latite dykes.
The less well defined Lucho Zone, is located on Cerro Chacay, and has been peripherally drill tested by two holes for which assay information is unavailable, one of which had primary copper sulphides reported and both of which have visible chalcocite in the drill cuttings left on site. The smaller Martin zone, located between Nacho and Lucho has been tested on its periphery by a single MCAL hole, which intersected mixed copper oxide and sulphide mineralization, in a potassically altered diorite porphyry.
Coro owns 100% of the Chacay property, subject to a 2% Net Profits Interest with a US$2 million cap, payable to First Quantum Minerals. Maps and sections showing the results of the Titan survey and other information on Chacay will be available on the Company’s website shortly.
