VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 19, 2012) - Coro Mining Corp. ("Coro" or the "Company") (News - Market indicators) is pleased to announce the results from the recently completed Phase III, 36 hole (4,028m) infill 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. Significant intersections from this infill program, which was completed on 50m centres, are shown on Table 1 below. 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, "The infill drilling has confirmed that Berta has potential to host a relatively modest sized, near surface, oxide deposit that we believe can be placed into production quickly and cheaply, and thus generate cash flow for our Chilean exploration program. We will now proceed to produce an NI43-101 compliant resource estimate for Berta Sur and Berta Central. A preliminary metallurgical column test work program is in progress and an environmental base line study will be initiated shortly."

No significant intersections were received from holes BR-59, BR-60, BR-75 to BR-78, BR-83 to 85, BR-87 to 88 and BR-92, which were drilled at the edge of the known mineralization. All drill hole locations are shown on Figure 1 and a typical cross section is shown on Figure 2. Copper equivalents were calculated at $3.00/lb Cu and $12/lb Mo, with no adjustment for metallurgical recoveries. In particular, no molybdenum would be recovered from the envisaged oxide operation.

About Berta

Mineralization, as defined by drilling, mapping and grid geochemistry, occurs in three principal areas; Berta Sur, Central and Norte, and is associated with sub-vertical, elongate potassically altered porphyry intrusive bodies and related hydrothermal and intrusive breccias, emplaced into a tonalite stock. At Berta Sur, this mineralization is present within a roughly horseshoe shape area with oxidation extending from surface to depths of 50m to 100m. Berta Central comprises a smaller body, located immediately north of Berta Sur, which was the focus for previous artisanal mining, as well as several smaller NW oriented zones. Berta Norte comprises several, discreet, NW oriented zones of mineralization, individually 25-85m in width and 100-250m in strike length, partially gravel covered, and mostly intersected at depth as sulphides in Coro's drilling. Copper and molybdenum mineralization broadly occur together at Berta although copper can occur without molybdenum and vice versa.

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 Diamond drilling (9 holes, 3,311.4m) in 2006-2007. All of these third party 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 these RC holes, all holes were assayed for molybdenum.

Coro has completed a total of 92 RC holes, (18,872m) in three phases starting in June 2011. For completeness, all significant intersections from Coro's Phase I and II drilling are shown on Table 2, which includes previously unreported CuS results, and minor adjustments to previously reported intervals. Collar coordinates for all Coro RC holes are shown on Table 3.

All Coro 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, Geominco, 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#. All holes were assayed for CuT and Mo, with oxide intersections containing greater than 0.1%CuT also assayed for CuS. A full QA/QC program, involving insertion of appropriate blanks, standards and duplicates was employed with acceptable results.

Sergio Rivera, Vice President of Exploration, Coro Mining Corp, a geologist with more than 30 years of experience and a member of the Colegio de Geologos de Chile and of the Instituto de Ingenieros de Minas de Chile, was responsible for the design and execution of the drilling program and is the Qualified Person for the purposes of NI 43-101. Alan Stephens, FIMMM, President and CEO, of Coro Mining Corp, a geologist with more than 36 years of experience is responsible for the contents of this news release.
