News Release 13-08

August 8th, Coro Mining Corp. (“Coro” or the “Company”) (TSX Symbol: COP) is pleased to announce that its subsidiary, Minera Coro Chile Ltda. (“MCC”) has signed a Term Sheet with Minera Aurex (Chile) Limitada (“Aurex”), an indirect subsidiary of Freeport-McMoRan Copper & Gold Inc., for Aurex to acquire an interest in MCC’s Payen Property. The 1,225 hectare Property is located approximately 90km NNE of La Serena, 4km W of the Panamerican Highway and approximately 47km from the coast, in the III Region of Chile, at an elevation of 1,100m (Figure 1). Aurex and MCC intend to execute a final agreement on or before September 15th 2013, subject to Aurex’s satisfactory completion of due diligence by September 10th 2013. MCC has granted Aurex an exclusive right to acquire its interest in the property.

Coro is also pleased to announce that it has renegotiated the acquisition terms for its El Desesperado porphyry copper project, located 7km NW of Calama in the II Region of Chile.

Alan Stephens, President and CEO of Coro commented, “We believe that Payen has the potential to host a major copper-gold porphyry deposit, and we look forward to seeing the results of Aurex’s exploration program as it develops. This represents further progress in Coro’s strategy of bringing in partners for its projects in these difficult markets, and follows our recent announcements regarding advancing our Berta project to production with an experienced Chilean engineering company as our partner. We are also pleased to have renegotiated the terms of our El Desesperado option, which will facilitate its ongoing exploration. “

About Payen
The large NE-SW oriented Pajonales alteration zone is located in the same 90-110 million year old belt of porphyry copper-gold deposits as Teck’s Andacollo mine, Cemin’s Dos Amigos mine, PanAust’s Inca de Oro & Carmen projects and Hot Chili’s Frontera project, which is located some 2.5km SE of the Payen property boundary.

The Payen property covers the northeastern third of the Pajonales alteration zone, where it is at its widest, and where the alteration appears most intense. The northern end of the property is transected by a NW fault which has uplifted to the north and exposed a potassically altered and quartz stockworked diorite porphyry with associated copper-gold mineralization. This has been subjected to reverse circulation drilling carried out by the Property owner in 2009, and diamond drilling completed by a private Chilean company in 2011-2012. Results of this drilling were summarized in the Company’s news release of October 17th 2012.

This mineralization is associated with a magnetic high anomaly, and Coro’s exploration has shown that several other similar mag highs are present on the property, coinciding with outcropping mineralized diorite porphyry stocks. Much of the remainder of the property hosts extensive phyllic alteration with outcropping leached cap, quartz stockworking, remnant copper oxides, and associated magnetic low and copper geochemical anomalies. High sulphidation alteration, including phreatomagmatic breccias and silicified ledges with anomalous gold, indicative of a remnant lithocap are exposed at the highest elevations. Previous geochemical sampling has indicated the presence of strongly anomalous copper associated with certain areas of the phyllic alteration, which Coro believes have good potential to host chalcocite enrichment.

The Property is subject to a 2.5%NSR, of which half (1.25%NSR) may be purchased for US$10,000,000 at any time up to Commencement of Commercial Production.

El Desesperado Project; Renegotiated Terms
Coro and the property owners have agreed to reschedule the option payments for the El Desesperado property as shown in Table 2 below.
