Coro Intersects 36 Metres at 2.43% Copper +0.102% Molybdenum + 5.8 G/T Silver at LLancahue Property
|November 19, 2009, Coro Mining Corp. ("Coro" or the "Company") (TSX Symbol: COP) is pleased to announce results from a 6 hole 1,059m RC drilling program at its 100% owned Llancahue property, located 38km south west of the city of Talca in central Chile. The objective of this short program was to follow up a previous intersect of 100m at 1.375% CuT + 0.015% Mo+ 3.8g/t Ag in hole LLA-07 drilled earlier this year. The location of the 6 holes, which were all drilled at inclinations of -60 degrees, and the holes drilled previously, is shown on the accompanying map. Significant assay results are shown on the table below;|
Hole LR-02 aimed at offsetting LR-01 to the south was abandoned at 136m before hitting target depth. Both holes LR-03 which offset LR-01 to the north and LR-05 drilled to the south of hole LR-04, intersected propylitically altered wallrock intrusive with traces of chalcopyrite, which have not yet been assayed. Hole LR-06 was a wild cat hole drilled to the west of Llancahue which also intersected propylitically altered wallrock, similar to holes LLA-01to 06 drilled earlier this year.
Mineralization at Llancahue, as currently understood, is hosted by an apical hydrothermal breccia developed around a sub vertical finger of strongly potassically altered diorite, and comprises disseminated and veinlet chalcopyrite, bornite and molybdenite. The drilling to date suggests that this mineralized intrusive, and its brecciated contact zone is of restricted areal extent. However, the intensity of the alteration and the accompanying high grade copper molybdenum mineralization, together with the extensive propylitic halo, support the concept that a larger body of mineralized diorite may be present under cover to the west of the area drilled. This is further supported by the presence of strongly potassically altered, chalcopyrite and bornite mineralized breccia float found in two other locations on the property, and by the increasing intensity of alteration around the northern and western margin of the covered area.
Alan Stephens, President and CEO commented, "We continue to be encouraged by the grade, style and intensity of mineralization at Llancahue, which is both intrusive and breccia hosted. The extensive propylitic alteration is moderately magnetic, while the copper molybdenum mineralization is associated with complete magnetite destruction. Accordingly, we will extend the existing ground magnetic survey to cover the large covered area located to the south and west of the drilled mineralization, as well as completing alteration mapping of the covered area margins in order to define targets for follow up drilling."
All RC holes were sampled on a 2m continuous basis, with samples riffle split on site and one quarter sent to the Andes Analytical Assaying laboratory in Santiago. A second quarter was stored at a MCAL facility for reference. Samples were regularly transported to the laboratory by MCAL. Samples were prepared using the following standard protocol: drying, crushing to better than 80% passing -10#, homogenizing, splitting and pulverizing a 400g subsample to 95% passing -150#. All samples were digested in Aqua Regia and assayed by means of ICP and AA in samples exceeding the limits of the ICP (>10,000ppm). A full QA/QC program, involving insertion of appropriate blanks, standards and duplicates was employed with acceptable results.
Angelo Peri, VP Exploration, Coro, a geologist with more than 24 years was responsible for the design and conduct of the exploration, and Alan Stephens, FIMMM, President and CEO, of Coro, a geologist with more than 34 years of experience is the Qualified Person for the purposes of NI-43-101.
