Coro Mining Corp.: Drill Results From Salvadora Property

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 20, 2007) - Coro Mining Corp. ("Coro" or the "Company") (TSX:COP) is pleased to announce reverse circulation (RC) drilling results from the Salvadora Property, part of its Barreal Seco and Satellites Project in Chile.

In June and July, the Company drilled 16 RC holes for a total of 2,376 meters aimed at extending copper oxide and sulphide mineralization previously defined by drilling in 2006. Assay results have been received for all holes and are shown on the table below. The assay results are highlighted by an intersection in hole SAL 34, of 84m at 0.46%CuT in copper oxides, starting at surface, with mineralization open to the northwest under cover, and an intersection in hole SAL 36 of 16m at 1.70% in sulphides before the hole was lost in mineralization, with the last 2m assaying 2.34%CuT. The mineralization intersected in SAL 36 was found under cover and demonstrates the potential for additional blind mineralization at Salvadora.

The true-width of the mineralization has not been determined by these drill programs.

The Company intends to conduct additional ground geophysics before the end of the year in order to better define the distribution of the mineralization and its possible extensions under cover, prior to embarking on a further round of drilling. Preliminary metallurgical testwork is also planned for the oxide mineralization.

Alan Stephens, President and CEO of Coro commented, "We are encouraged by the results obtained in this round of drilling. We continue to view Salvadora as having the potential to contribute positively to the overall Barreal Seco and Satellites resource base."

About the Salvadora Property:

The Salvadora Property is located 17km southwest of Coro's Barreal Seco deposit and 58km northeast of the port of Chanaral in the III Region of Chile. Coro is evaluating Salvadora as a potential source of additional copper resources that could be developed in conjunction with any operation that may be developed at Barreal Seco. In February 2007, an independently estimated, in pit, Measured and Indicated copper oxide resource was defined at Barreal Seco, at a 0.30% CuT cutoff, of 26,289,372 tonnes @ 0.56% CuT as set out in the "Technical Report on the Barreal Seco Property" prepared by AMEC Americas Limited, and filed and available for review on SEDAR as www.sedar.com.

Previous drilling at Salvadora by the Company in 2006 comprised 26 RC holes for 3,064m, which intersected both oxide and sulphide copper mineralization. Assay results for that drilling campaign are shown in the table below.

As currently defined, Salvadora comprises a northwest-southeast oriented Iron Oxide Copper Gold deposit hosted by andesitic volcanics intruded by diorite dykes and irregular bodies. Mineralization, associated with disseminated specularite and brecciation, is best developed in the contact regions of these intrusives and forms several sub-parallel, steeply dipping, tabular bodies, each of which vary in thickness from 10 to 100m approximately. Outcrop in the prospect area is extremely limited but based on drilling and trenching, mineralization has been traced over a strike length of approximately 1,000m, open at both ends. A small outcrop of copper oxide/specularite mineralization occurs some 300m northwest of the last drillhole, suggesting additional potential in this direction. Oxidation occurs to vertical depths of 60-100m, sulphide mineralization has been intersected to depths of approximately 150m, and remains open at depth. For further information and drill plan map please refer to the Company's website.

All RC holes were sampled on a 2m continuous basis, with samples riffle split on site and one quarter sent to the ALS Chemex laboratory in La Serena. A second quarter was stored at a Company facility for reference. Samples were regularly collected at Chanaral by a truck belonging to ALS Chemex and transported to the laboratory. Samples were prepared using the following standard protocol: drying, crushing to better than 95% passing 2mm, splitting and pulverizing a 200g subsample to 95% passing 0.106mm. All samples were analyzed for CuT and CuSol; some samples were assayed for Au. A full QA/QC program, involving insertion of appropriate blanks, standards and duplicates was employed with acceptable results.

Angelo Peri, VP Exploration, Coro Mining Corp, a geologist with more than 22 years experience was responsible for the design and conduct of the exploration, and Alan Stephens, FIMMM, President and CEO, of Coro Mining Corp., a geologist with more than 32 years experience is the Qualified Person for the purposes of NI 43-101, has reviewed the technical information contained in this news release.
