VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 1, 2012) - Coro Mining Corp. (TSX:COP) ("Coro" or the "Company") is pleased to announce that it has completed surface exploration and an 8 hole 2,290m reverse circulation (RC) drilling program at its El Desesperado copper project, located 7 km NW of the city of Calama in the II Region of Chile, and immediately west of Codelco's Toki Cluster deposits.

The drill program was designed to provide an initial test of an ~4km2 prospective area of porphyry copper style alteration and anomalous copper geochemistry resulting from the Company's mapping and sampling program completed earlier this year. This prospective area includes the El D Norte target, where leached cap, porphyry style alteration and anomalous geochemistry have been defined over an area of 1,500m x 700m, partially covered by landslips, extending WSW from the eastern property boundary and encompassing the old Quetena open pit workings. It also includes the El D Sur target where scattered outcrops of leached cap, porphyry style alteration and anomalous geochemistry, largely covered by overburden, occur over an area of 1,400 x 500m. The target extends NNE from the southern property boundary, is limited by the property boundary to the east, and is open to the north under cover.

A total of 5 RC holes (1,544m) were completed in the El D Norte target and 3 RC holes (746m) in the El D Sur; several holes did not reach their planned 400m depths due to drilling difficulties caused by the presence of water. Drillhole locations are shown on Table 1 and Figure 1.

Alan Stephens, President and CEO of Coro, commented, "We are pleased with the progress of our exploration at El Desesperado. All 8 holes intersected porphyry copper style mineralization and alteration over significant widths beneath a leached cap, and we look forward to receiving the assay results in due course."

About El Desesperado

Coro believes there is good potential on the El Desesperado property to host mineralization of similar style to the adjacent Toki Cluster deposits (Toki, Quetena, Genoveva, Opache, Miranda and Pulucktur). These are associated with swarms of NNE oriented Eocene age porphyry dykes and stocks, intruded into both Paleozoic volcanics and precursor Tertiary plutons. Zones of low grade copper mineralization associated with potassic alteration are related to the porphyries and higher copper grades occur where this has been overprinted by sericite alteration, or where later veining is present. The Toki Cluster deposits have been oxidized to depths in excess of 100m beneath the gravel cover which overlays all of them, and host major copper oxide resources, as well as significant underlying primary sulphide mineralization, and in the case of Opache and Pulucktur, secondary enrichment blankets.

Small scale open pit mining and leaching of copper oxide bearing breccias, took place at the old Quetena Mine on the property during the 1960-70's, and it was subsequently explored by two major mining companies, firstly in 1997-98 prior to the discovery of the Toki Cluster; and secondly in 2004. The first company completed wide spaced reverse circulation and diamond drilling (11 holes, 2,582m), mostly aimed at testing geophysical targets, while the second company completed vertical reverse circulation drilling (2 holes, 700m) which tested two conceptual targets. In neither case, was significant mineralization intersected.

In December 2011, Codelco initiated the permitting process for production of cathode copper from the combined Quetena and Genoveva deposits. According to the publicly available Environmental Impact Study, this will involve an open pit at each of the deposits, the trucking of 30,000tpd of higher grade ore to the existing SXEW facilities at Chuquicamata, and 60,000tpd of Run of Mine dump leaching at the project site, followed by pumping of solution to Chuquicamata. Planned production is 528,000 tonnes of cathode copper over the 10 year life of the project, with an average production of 62,000 tpy Cu in the first five years. Capital investment is estimated to be US$244,000,000.

Genoveva is located ~1km E of the El Desesperado property, Opache ~2km to the ESE, and Pulucktur, ~1.5km to the SSW (Figure 1).
