Coro Announces Development Alternative for San Jorge and Highlights from Copper Leach Project Preliminary Feasibility Study

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 5, 2012) - Coro Mining Corporation ("Coro", or the "Company") (TSX: COP) is pleased to announce a new development alternative for San Jorge and the highlights from the Copper Leach Project ("the Project") based on a Preliminary Feasibility Study ("PFS") (the "Propipe PFS") by Process and Pipeline Projects SA. ("Propipe"), based in Santiago, Chile, which will be filed on SEDAR within 45 days. The Project is located in the Provinces of Mendoza and San Juan, Argentina. This announcement describes the highlights from the Propipe PFS for development of the Project using heap leaching only, involving the construction of an SXEW heap leach plant outside of the province of Mendoza in the neighbouring pro-mining province of San Juan. Ore transport would be by means of a 22km long railway line to be constructed for the Project. Current legislation in the Province of Mendoza prohibits the use sulphuric acid required in heap leaching of copper ore. The Company and Propipe have received a legal opinion that there should be no legal impediment to the transport of ore between Mendoza and San Juan.

This PFS takes into account the outcomes of an engineering study completed in 2008 by Ausenco Canada Inc. ("Ausenco"), as announced in the Company's news release dated April 3, 2008, and revised and updated by Propipe in late 2011. The Propipe PFS includes the resources, reserves, open pit mine plan, operating and capital costs and financial analysis for a leach Project which describes the production of up to 25,000 tonnes (55 million lbs) per year of copper cathode for a period of 10 years. It is a comprehensive study of the viability of the Project that has advanced to a stage where the mining method has been established and an effective method of mineral processing has been determined, and includes a financial analysis based on reasonable assumptions of technical, engineering, legal, operating, economic, social, and environmental factors and the evaluation of other relevant factors which are sufficient to determine if all or part of the mineral resource may be classified as a mineral reserve.

The Propipe PFS was prepared in conjunction with a NI 43-101 resource estimate completed by NCL Ingenieria y Construccion S.A. ("NCL"), Santiago, Chile, as announced in the Company's news release on January 16, 2008. No additional drilling has been completed on the Project since the date of that estimate, and the resource has not been updated since then. The mine plan is unchanged from the Ausenco report, and no additional metallurgical testwork has been completed since the date of the Ausenco report. Full particulars of all exploration data, the key assumptions, parameters and methods used to estimate mineral resources, quality control and data verification methods are as disclosed in the Ausenceo report, filed by the Company on SEDAR on May 23, 2008.

Alan Stephens, President and CEO of Coro commented, "Coro is pleased with the outcome of this latest study which once again confirms the robust nature of San Jorge. The Company is confident that this revised San Jorge development plan can be executed in an environmentally responsible manner to the lasting economic and social benefit of the Provinces of Mendoza and San Juan. In addition, the Project has the potential to more than satisfy Argentina's current consumption of copper, and thus could be developed in accordance with the country's stated policy of reducing imports. We further believe that the combination of what would essentially be a rock quarrying operation, similar to many others currently operating in Mendoza, together with a processing plant located in San Juan, which has a vibrant and well developed metalliferous mining industry, should satisfy essentially all of the objections that were raised to the previous flotation project which was denied legislative ratification in Mendoza last year.

A copy of this news release together with an accompanying letter will be sent to all of the members of the recently formed Federal Organisation of Mining Provinces ("OFEMI"), which includes Mendoza, in order that they may consider the importance of this Project to Argentina. Upon the successful development of this leach project the Company will consider the alternatives for a flotation project."

I. Mineral Resources:

San Jorge is a mid-sized porphyry copper gold deposit, containing oxide, enriched, and primary mineralization. Resources are contained within Oxide material, which can only be processed by heap leach methods; Enriched material, which could be processed by heap leach or flotation; and Primary material which can only be processed by flotation methods. The table below summarizes mineral resources on the San Jorge property. Mineral reserves disclosed on the following page are included in the mineral resource numbers below. The mineral resource calculations described below are effective as at January 16, 2008 and have remained unchanged since this date.

II. Mineral Reserves, Mining, Processing and Production Plan:

The Project contemplates an open pit mine to extract oxide and enriched material and their processing by heap leach methods, (including bacterial leaching for the enriched material) and recovery of cathode copper via solvent extraction-electro winning (SXEW) together with an on-site sulphur burning acid plant. Overall ore contained in the mine plan developed by NCL is 48.4 million tonnes, with an average grade of 0.61% CuT. The Mineral Reserves are categorized as 83% Proven and 17% Probable of which 55% is oxide and 45% is enriched as is set out in Table 3. The Inferred resources are currently considered as waste. The mineral reserve calculations described below are effective as at May 23, 2008 and subsequently validated by NCL.

The mine plan was driven by two factors; firstly to process up to a maximum of 6.3 million tonnes per year in the crushing plant; and secondly to minimize the overall strip ratio, especially in the early years. This plan to place a total of 48.4 million tonnes of oxide and enriched material on to heap leach pads was then used by Propipe to prepare a processing plan for the production of up to 25,000 tonnes per year of copper cathodes during the Life of Mine ("LOM") as is set out in Table 4:

The overall LOM strip ratio is relatively low at 0.77:1, peaking at 1.65:1 in the fifth year with a minimum strip ratio of 0.25:1 in year eight.

Since the Ausenco engineering study was published in May 2008, the economic parameters concerning capital and operating costs and copper price have changed significantly. Costs have increased due to escalation of labour cost, diesel, power, consumables and materials, plus the additional transport cost resulting from the proposed location of the process plant 22 km from the mine. At the same time, the copper prices have also increased significantly, compensating for the upward trend in costs. The technical parameters of the project remained unchanged from the Ausenco study, except for the location of the heap leach operation. In order to assess changes in the economic parameters since 2008, NCL carried out an analysis of the validity of the open pit design, reserves and mine plan evaluated in the Ausenco study, and concluded that all those elements are valid under the conditions of the current study. The main conclusion of the analysis is that increases in the operating costs are mostly offset by increases in copper price, to the extent that the selected pit from a Whittle exercise run using the current parameters is virtually identical to the pit selected in the 2008 Study. The validity of the Ausenco mine plan was therefore confirmed; it preferentially extracts oxide ore early in the mine life, delaying the mining and processing of the enriched ore which had slower leach kinetics, as well as deferring project capital. The production plan contains 223,400 tonnes (492 million lbs) of recoverable copper as cathode.

A total of seventeen 4 & 6 m column tests were completed at SGS Laboratories, Santiago, Chile in 2008. The metallurgical parameters were validated by Propipe from a diffusion controlled leaching model developed by Ausenco in 2008. That model used a scale-up factor of 1.5 and derivation of the projected leach cycle of 115 days for oxide and 150 days for enriched, average acid consumptions of 26.1 kg/t for oxide and 18.3 kg/t for enriched, and recoveries of 85% of total copper for oxide and 66.3% of total copper for enriched.

Capital and operating cost estimates were updated by Propipe and reflect the market environment in Argentina (Q4 2011) for owner mining, crushing, agglomeration, transport and stacking of ore, acid production from a sulfur burning acid plant, cathode production by solvent extraction and electro-winning, and cathode transportation. After a series of trade off studies of the various power and acid supply alternatives, it was concluded that current and projected sulfuric acid shortages were best addressed by the inclusion of a 140,000 ton per year on-site sulfur burning acid plant. The acid and co-gen power plant was estimated to have a capital cost of $23.6 million, and was sized to provide the projected sulfuric acid requirements for the operation, and approximately half of the 10 MW required project power. The rest of the power will be supplied from the Argentinean grid in Calingasta located 93 km to the north of the leaching plant, in San Juan province, at a cost of $11.5 million.

Trade off studies were also performed to determine the most cost efficient way of hauling ore from the mine site to the leach process plant in San Juan. Trucking, conveyor and rail were studied, with the lowest operational cost and optimal technical alternative being a 22 km railway with 3,000 HP locomotive and 42 wagons of 56 tonnes capacity, for a total cost of $23.5 million. Water will be supplied by a 20 km pipeline from the El Tigre stream located in the Yalguaraz ranch, owned by Minera San Jorge.

All mineral resources have been estimated in accordance with the definition standards on mineral resources and mineral reserves of the Canadian Institute of Mining, Metallurgy and Petroleum referred to in National Instrument 43-101, commonly referred to as NI 43-101. U.S. reporting requirements for disclosure of mineral properties are governed by the United States Securities and Exchange Commission (SEC) Industry Guide 7. Canadian and Guide 7 standards are substantially different. This press release uses the terms "measured," "indicated" and "inferred" resources. Mineral resources which are not mineral reserves do not have demonstrated economic viability. We advise investors that while those terms are recognized and required by Canadian regulations, the SEC does not recognize them. Inferred mineral resources are considered too speculative geologically to have economic considerations applied to them that enable them to be categorized as mineral reserves.
