Coro Announces Drilling Results, Including 160m @ 0.74%CuT and Provides an Update for its Barreal Seco and Satellites Project in Northern Chile

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 21, 2007) - Coro Mining Corp. ("Coro" or the "Company") (TSX:COP) is pleased to announce Reverse Circulation (RC) drilling results and provide an update for the advanced stage Barreal Seco and Satellites Project in Chile. The Project comprises the Barreal Seco deposit and the Salvadora, Flor de Lirio and Celeste Satellite Prospects.

A drilling program comprising a total of 43 RC holes for 8,510 meters has recently been completed at the Barreal Seco deposit aimed at: a) converting Inferred Oxide and Primary Sulphide resources to Measured and Indicated Category (14 holes/3,160m) (Resource Conversion Drilling); b) defining limits to the existing resource (18 holes/3,150m) ("Resource Limit Definition Drilling"); and c) exploring geophysical targets on the property (11 holes/2,200m) ("Exploration Drilling").

Alan Stephens, President and CEO of Coro, commented, "The Barreal Seco and Satellites Project continues to make good progress, and we are particularly pleased by the long sulphide intersections encountered in this latest drilling, highlighted by 160m @ 0.74%CuT in RBS 70 and 126m @ 0.77%CuT in RBS 72. In addition, good potential exists for the Salvadora Satellite Prospect to contribute oxide resources to the overall Project. We will be evaluating the potential for producing both copper cathode and copper in concentrates from the Project in our internal scoping study which is expected to be completed in the second quarter of 2008."

Resource Conversion Drilling: Holes RBS 70-75 were aimed at converting Primary Sulphide Inferred resources in the Main Zone of the Barreal Seco deposit to Indicated resource, while holes RBS 62-69 were aimed at converting Inferred Oxide and Primary Sulphide resources in the South East Zone of the deposit to Indicated category. Several holes ended in significant sulphide mineralization.

Resource Limit Definition Drilling: This drilling was aimed at defining the limits to the mineralization to the northwest (Holes RBS 39-42, 45), west (Holes RBS 76-81), and south east (Holes RBS 55-61) of the existing Barreal Seco resource. Additional oxide and sulphide mineralization was intersected in holes drilled immediately to the west and northwest of Barreal Seco as shown in the accompanying table. The remaining holes did not intersect significant mineralization and the deposit is now believed to be effectively closed off.

Project Update:

The Company continues to work towards completion of an internal scoping study for the Barreal Seco and Satellites Project, which is scheduled for the second quarter of 2008. Metallurgical testwork is underway for both Barreal Seco and Salvadora, and an updated resource estimate for Barreal Seco, incorporating these latest drilling results, is in progress. Drilling results for the Salvadora Satellite Prospect were released in NR07-08 on September 20th, 2007, and a gravity survey and additional RC drilling is anticipated to be completed at Salvadora before year end.

For further information about the Barreal Seco and Satellites Project and a drill plan map showing the recent drilling, please refer to the Company's website www.coromining.com or refer to the NI 43-101 Technical Report on the Barreal Seco Property dated February 2007 on SEDAR at www.sedar.com.

All RC holes were sampled on a 2 m 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 MCAL 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 70% passing -10#, splitting and pulverizing a 1,000 g subsample to 85% passing -200#. 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 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 of experience is the Qualified Person for the purposes of NI 43-101 and has reviewed the information in this new release.
