Mirasol Agrees to Sell its Interest in the Joaquin Silver-Gold Project to Coeur d'Alene Mines

Mirasol Agrees to Sell its Interest in the Joaquin Silver-Gold Project  to 
Coeur d'Alene Mines 
VANCOUVER, Dec. 11, 2012 /CNW/ - Mirasol Resources Ltd. (TSX-V: MRZ, 
Frankfurt: M8R) Mirasol Resources Ltd. ("Mirasol") is pleased to announce it 
has reached an agreement to sell its 49% interest in the Joaquin Silver-Gold 
Project, Argentina, to Coeur d'Alene Mines Corporation ("Coeur") (NYSE:CDE; 
TSX:CDM), which has been operating on the Joaquin Project through an Argentine 
subsidiary. 
Under the terms of the agreement, Mirasol will receive a total consideration 
of US$60 million, which includes a payment of approximately US$30 million in 
cash and a quantity of Coeur common shares valued at approximately US$30 
million based on the ten trading day volume weighted average price prior to 
the date of Mirasol's acceptance of Coeur's offer, in return for Coeur 
acquiring Mirasol's subsidiary which holds the Joaquin property. 
Mirasol's president and CEO, Mary Little, said, "Mirasol is delivering on its 
strategy of building value through making new discoveries in the areas where 
we explore. In the case of Joaquin, our partner Coeur plans to carry forward 
while we continue to engage in discovery-oriented exploration programs in 
Latin America. The proceeds of the deal will help sustain these efforts for 
the next several years. We are pleased to formalize the Joaquin sale and are 
committed to providing our shareholders with the best opportunities for 
exploration success." 
The transaction has been approved by the Boards of Directors of Mirasol 
Resources Ltd. and Coeur d'Alene Mines Corporation but remains subject to 
customary closing conditions, including the receipt of regulatory approvals. 
The transaction does not require the approval of the shareholders of either 
Coeur or Mirasol. 
In November 2006, Mirasol and Coeur entered into an exploration and joint 
venture option agreement with respect to the Joaquin project. In 2010, Coeur 
vested at 51% interest and has since proceeded to advance the project towards 
feasibility stage. 
The Joaquin silver-gold deposit is a grass roots discovery initially 
identified by Mirasol through its proprietary exploration approach, upon which 
Coeur has defined a resource of Canadian National Instrument N.I. 43-101 
mineral estimate of 38.4 million ounces silver in the Measured and Indicated 
categories plus 31.3 million ounces silver in the Inferred category. In 
addition, Joaquin contains 39,600 gold ounces in Measured and Indicated 
resources and 19,400 gold ounces in Inferred (Table 1 and Technical Report of 
September 21, 2012 at www.sedar.com). The N.I. 43-101 resource estimate was 
prepared by independent consulting firm NCL Ingenieria y Construccion Ltda. of 
Santiago, Chile, using a $30 per silver ounce and $1,500 per gold ounce price, 
and a resource cut-off of 30 g/t (grams per tonne) for silver oxide material 
and a 34 g/t silver cut-off for silver sulphide material, within 
Whittle(®)-estimated surface pit mine parameters.

Quality Assurance/Quality Control:
Coeur d'Alene has been operating the Joaquin project and generated the 
drilling data used in this news release and reported it to Mirasol. Drill core 
samples were submitted to Alex Stewart (Assayers), Argentina S.A. and ALS 
Laboratories, both ISO 9000-2000 accredited laboratories located in Mendoza, 
Argentina. Gold and silver results were determined using standard fire assay 
techniques on a 30 gram sample with a gravimetric finish for gold and silver. 
Coeur's QAQC program includes the insertion of blanks, standards and 
duplicates into the sample stream for Joaquin drill holes. Mirasol has 
performed an independent analysis of the QAQC data generated by Coeur. Dr. 
Paul Lhotka has reviewed the Coeur resource in this news release, and is a 
qualified person as defined by National Instrument 43-101. 
Exploration at Mirasol's Projects is supervised by Stephen C. Nano, Vice 
President of Exploration; Timothy Heenan, Exploration Manager; and Dr. Paul 
Lhotka, Principal Geologist. All technical information for the Company's 
projects is obtained and reported under a formal quality assurance and quality 
control (QA/QC) program. Drill core, rock chip and stream sediment samples are 
collected under the supervision of Company geologists in accordance with 
standard industry practice. Samples are dispatched via commercial transport to 
an ISO 9001:2000-accredited laboratory in Mendoza, Argentina for analysis. 
Results are routinely examined by an independent geochemist to ensure 
laboratory performance meets required standards. 
Assay results from diamond drill core or RC drill samples may be higher, lower 
or similar to results obtained from surface samples. 
Neither the TSX Venture Exchange nor its Regulation Services Provider (as that 
term is defined in the policies of the TSX Venture Exchange) accepts 
responsibility for the adequacy or accuracy of this release.
