Coro Announces 200 Meters at 0.70% Copper Equivalent at Berta Copper Project

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 27, 2011) - Coro Mining Corp. ("Coro" or the "Company") (TSX:COP) is pleased to announce the assay results from the recently completed 24 hole (4,360m) reverse circulation drilling program at its Berta Property, located approximately 20km west of the village of Inca de Oro in the III Region of Chile, at an elevation of 1,700m. Coro announced the terms for the 100% acquisition of Berta in its news release of June 13th 2011.

Alan Stephens, President and CEO of Coro commented, "We are pleased with the results of this first round of drilling at Berta, which successfully confirmed the results of previous work, and has provided a better understanding of the geological controls to mineralization. The drilling, combined with Coro's reconnaissance mapping, indicates that significant copper-molybdenum mineralization is hosted by multiple, broad, en-echelon, northwest oriented zones of sulphide veining and brecciation, with accompanying albite-chlorite alteration, associated with the emplacement of tonalite porphyry intrusive bodies. At least 10 such zones, each typically 50-100m wide and open ended, have been intersected by drilling within an area measuring approximately 1,500m x 400m. This initial drilling program was concentrated on only one of them. We are currently conducting grid geochemistry and a detailed IP survey, aimed at further defining the known mineralized zones as well as exploring other extensive and previously untested areas of similar alteration and mineralization encountered on the property. Upon completion of this work, we intend to conduct additional drilling at Berta."

All drill hole locations are shown on the attached plan maps, cross section and table.

Holes BR-15 to 18 bottomed in mineralization. Holes BR-02 to BR-08, and BR-10, 11, 21, 22 and 24 were aimed at defining the limits to the known mineralization and had no significant intersections. However, holes BR-02 to 07, drilled to 100m depth, did not reach sulphides and together with holes BR-21 and 23, encountered deep leaching. Copper equivalents were calculated at $2.75/lb Cu, $12/lb Mo and $1,000/oz Au.

All RC holes were sampled on a 2 m continuous basis, with samples riffle split on site and one quarter sent to the Andes Analytical Assaying laboratory in Copiapo for preparation and then to their assay laboratory in Santiago. A second quarter was stored on site for reference. Samples were transported to the laboratory by Andes Analytical Assaying under the supervision of Minera Coro Chile Ltda.'s contractor, South American Management SA, who also logged the drill cuttings. Samples were prepared using the following standard protocol: drying, crushing to better than 80% passing -10#, homogenizing, splitting and pulverizing a 400 g subsample to 95% passing -150#. Holes BR-13 to 24 were analyzed by sequential assaying for CuT, CuSol and CuCN and for Au and Mo, whereas holes BR-01 to BR-07 were assayed for CuT and Mo only, and holes BR08 to BR-12 were assayed for CuT, Au and Mo. A full QA/QC program, involving insertion of appropriate blanks, standards and duplicates was employed with acceptable results.

About Berta

Berta has previously been explored by two major mining companies in the 1990's who completed wide spaced shallow percussion drilling (48 holes, 1,090m), reverse circulation ("RC") drilling (49 holes, 6,033m), and bulldozer trenching. More recently, Grandcru Resources Corp. completed a ground magnetic survey and diamond drilling (9 holes, 3,311.4m) in 2006-2007. All of the previous holes were assayed for total copper (%CuT), and the oxide sections of 42 of the RC holes were assayed for acid soluble copper. With the exception of 42 of the RC holes, all holes were assayed for molybdenum. Small scale artisanal mining of copper oxide bearing breccias, is currently taking place on the property. Copper oxide mineralization typically extends from surface to 25-50m depth, but reaches more than 100m in places.
