MARI Marimaca Copper Corp

Coro Mining Corp. ("Coro" or the "Company") (TSX:COP) is pleased to provide an
update on its projects in Chile and Argentina, and progress on the
identification and acquisition of new opportunities.


San Jorge Project

As stated in our news release of August 27th, 2011, Coro has been reviewing its
alternatives for seeking legal redress and compensation from the Mendoza
government resulting from the unlawful denial of the ratification of the
Company's valid and approved Environmental Impact Declaration. This legal review
has now been completed and Coro will make a decision whether to file suit
against the Mendoza government and certain individuals, shortly. The Company is
also finalizing an engineering study which defines an alternative development
strategy for San Jorge, and which we intend to present to the Argentinean
authorities in the next few weeks. Results of this study, and the outcome of
these discussions, will be released in Q1 12. 


Berta Project 

Located approximately 20km west of the village of Inca de Oro in the III Region
of Chile, Coro announced the terms for the 100% acquisition of Berta in its news
release of June 13th 2011 and released encouraging assay results from a 24 hole
RC drilling program completed at the Berta Sur section of the property, on
September 27th, 2011. The Company has now completed a grid geochemistry sampling
program, an IP survey, initial reconnaissance mapping, and has expanded the
property position by staking. In addition to the mineralization drilled at Berta
Sur, this work has resulted in the identification of several strongly feldspar
altered porphyritic intrusives containing disseminated, oxidized chalcopyrite
with coincident strong copper geochemistry, exposed intermittently over a strike
length of 2,000m, and open to the south, adjacent to a major NNE oriented strand
of the Chivato fault, (See Figure 1). The northernmost 700m of this mineralized
trend has a coincident strong IP chargeability anomaly, open to the NNE. This
newly identified mineralization has essentially not been drill tested
previously. Additional geochemical and geophysical anomalies and associated
mineralization requiring follow up, have also been identified both on the
optioned property and on the newly staked ground. Detailed mapping is in
progress prior to the initiation of a second round of drilling later in Q1. 


Chacay Project

Located 12km southeast of Teck Resources Relincho copper project, and 50km east
of the city of Vallenar in the III Region of Chile, Coro announced continuing
encouraging diamond drill results in its news release of October 12th, 2011. The
Company has now completed an extensive petrographic review of drill samples and
will be completing detailed surface mapping aimed at providing a better
understanding of the project's geology, particularly the interrelationships of
the various mineralized porphyry types that have been identified to date. The
review of drill samples and surface outcrops confirms that the enrichment
blanket is related to the development of extensive phyllic alteration which
affects a granodiorite host rock and various types of porphyries that intrude
it. The mapping will be succeeded by a drill program to define a resource for
the enrichment blanket and potentially, to further explore the underlying
primary copper-gold-molybdenum mineralization, where the presence of bornite has
now been confirmed.


New Projects

Coro has identified three new porphyry copper prospects in northern Chile, which
have potential to host significant mineralization; terms have been agreed with
owners of one of these properties and discussions are advanced on a second.
Further details will be announced once the relevant contracts have been
executed. A generative exploration program for both porphyry copper and gold
deposits is under way. 


Alan Stephens, President and CEO of Coro commented, "We anticipate that 2012
will be an exciting year for Coro as we add to our portfolio of significant
porphyry copper projects in Chile, and systematically drill them. We also
anticipate that the future of San Jorge will become much clearer over the coming
months."


As of December 31, 2011 the Company had approximately CA$12 million in cash, and
is well funded to advance its projects.
