MARI Marimaca Copper Corp

Coro Mining Corp. ("Coro" or the "Company") (TSX:COP) is pleased to announce
that it has entered into an option agreement to acquire the El Inca Property
from a local Chilean company. The 1,706 hectare Property is located
approximately 4km northeast of the village of Inca de Oro, in the III Region of
Chile, at an elevation of 1,700m (Figure 1). The Property is also located
approximately 20km east of the Company's Berta project, where a resource
definition drill program and sampling for metallurgical test work, is currently
in progress. The Inca de Oro porphyry copper-gold project, owned by a
PanAust/Codelco joint venture, borders the Property immediately to southwest. 


In July 2012, PanAust announced the results of a feasibility study at Inca de
Oro for a 12mt per year flotation operation which concluded, among other things,
that the project would not provide a sufficient return for the joint venture
partners, but that project economics would be materially enhanced by the
delineation of additional mineral resources. Details of this feasibility study
can be found on the PanAust website.


Alan Stephens, President and CEO of Coro commented, "The El Inca Property is
subdivided into 3 claim groups, two of which are subject to rights of first
refusal ("ROFR"). The largest claim group named Porvenir, which is not subject
to a ROFR, includes a large gravel covered area approximately 2km to the
northeast of the PanAust/Codelco deposit which we believe may host a major
porphyry copper-gold deposit similar to Inca de Oro, which was discovered in
2005 by Codelco and is covered by 50-80m of gravel. We intend to initiate a
reverse circulation (RC) drill program to test this target immediately after the
completion of our Berta project infill drill program. We also see potential for
smaller tonnage, oxide copper mineralization in a cluster of hydrothermal
breccia pipes which outcrop in the eastern section of the Property. Two of these
breccia pipes, Delirio and Tucumana, are located within the remaining two claim
groups, named Calaverita and Delirio, each of which are subject to ROFRs, while
a third pipe, Manto Cuba, is located within the Porvenir claim group. We intend
to evaluate these breccias in order to assess their potential to provide oxide
feed to our Berta project."


El Inca Option Terms

Coro may acquire 100% of the El Inca property for a total of up to
CAD$10,000,000, depending on the exercise of the ROFRs, by making the following
staged option payments:

About El Inca

The outcropping area of the El Inca property has been subject to artisanal
scale, open pit mining of high grade oxide mineralization, hosted by several
hydrothermal breccia bodies. The wider area of the breccias, including claims
not forming part of the Inca Property, was explored by Samex Mining Corp. during
the period 2006-9. According to published information, this included diamond
drilling, underground and surface sampling, and an Induced Polarization survey,
but Coro does not have access to the details of this work. Apart from 2 old
Codelco RC holes located in the extreme southwest corner of the property, no
drilling has been completed in the covered area of the Porvenir claim group
which constitutes the Company's primary target. Figure 2 shows the 3 claim
groups and the location of the Property relative to the Inca de Oro project, and
to the paved highway.


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 exploration program and is the Qualified Person
for the purposes of NI 43-101. Alan Stephens, FIMMM, President and CEO, of Coro
