Coro Mining Corp. ("Coro" or the "Company") (TSX:COP) is pleased to announce
that its subsidiary, Minera Coro Chile Ltda. ("MCC") has signed a Term Sheet
with Minera Aurex (Chile) Limitada ("Aurex"), an indirect subsidiary of
Freeport-McMoRan Copper & Gold Inc., for Aurex to acquire an interest in MCC's
Payen Property. The 1,225 hectare Property is located approximately 90km NNE of
La Serena, 4km W of the Panamerican Highway and approximately 47km from the
coast, in the III Region of Chile, at an elevation of 1,100m (Figure 1). Aurex
and MCC intend to execute a final agreement on or before September 15th 2013,
subject to Aurex's satisfactory completion of due diligence by September 10th
2013. MCC has granted Aurex an exclusive right to acquire its interest in the
property.


Coro is also pleased to announce that it has renegotiated the acquisition terms
for its El Desesperado porphyry copper project, located 7km NW of Calama in the
II Region of Chile.


Alan Stephens, President and CEO of Coro commented, "We believe that Payen has
the potential to host a major copper-gold porphyry deposit, and we look forward
to seeing the results of Aurex's exploration program as it develops. This
represents further progress in Coro's strategy of bringing in partners for its
projects in these difficult markets, and follows our recent announcements
regarding advancing our Berta project to production with an experienced Chilean
engineering company as our partner. We are also pleased to have renegotiated the
terms of our El Desesperado option, which will facilitate its ongoing
exploration."


Acquisition Terms

As shown on Table 1 below, Aurex may acquire a 70% interest in Payen by
completing all of the following;




--  Paying US$16,500,000 in option payments to the underlying Property owner
--  Expending US$13,000,000 in work commitments on the Property 
--  Paying US$1,000,000 to MCC 
--  Paying an additional US$21,500,000 to MCC upon formation of an operating

The operating company may complete a Feasibility Study to NI43-101 standards on
a best efforts basis by October 10, 2019 at Aurex's expense, at which point MCC
will have the option of refunding 20% of the costs of the Feasibility Study to
Aurex and thereby own 20% of the operating company, or will immediately dilute
to a 2% Net Smelter Return ("NSR"). If MCC elects to refund its 20% share of the
Feasibility Study, the operating company shareholders will be responsible for
all future costs on a pro-rata basis, or be subject to dilution.


About Payen

The large NE-SW oriented Pajonales alteration zone is located in the same 90-110
million year old belt of porphyry copper-gold deposits as Teck's Andacollo mine,
Cemin's Dos Amigos mine, PanAust's Inca de Oro & Carmen projects and Hot Chili's
Frontera project, which is located some 2.5km SE of the Payen property boundary.



The Payen property covers the northeastern third of the Pajonales alteration
zone, where it is at its widest, and where the alteration appears most intense.
The northern end of the property is transected by a NW fault which has uplifted
to the north and exposed a potassically altered and quartz stockworked diorite
porphyry with associated copper-gold mineralization. This has been subjected to
reverse circulation drilling carried out by the Property owner in 2009, and
diamond drilling completed by a private Chilean company in 2011-2012. Results of
this drilling were summarized in the Company's news release of October 17th
2012. 


This mineralization is associated with a magnetic high anomaly, and Coro's
exploration has shown that several other similar mag highs are present on the
property, coinciding with outcropping mineralized diorite porphyry stocks. Much
of the remainder of the property hosts extensive phyllic alteration with
outcropping leached cap, quartz stockworking, remnant copper oxides, and
associated magnetic low and copper geochemical anomalies. High sulphidation
alteration, including phreatomagmatic breccias and silicified ledges with
anomalous gold, indicative of a remnant lithocap are exposed at the highest
elevations. Previous geochemical sampling has indicated the presence of strongly
anomalous copper associated with certain areas of the phyllic alteration, which
Coro believes have good potential to host chalcocite enrichment. 


The Property is subject to a 2.5%NSR, of which half (1.25%NSR) may be purchased
for US$10,000,000 at any time up to Commencement of Commercial Production.


El Desesperado Project; Renegotiated Terms

Coro and the property owners have agreed to reschedule the option payments for
the El Desesperado property as shown in Table 2 below.

About Coro Mining Corp.:

The Company was founded with the goal of building a mining company focused on
medium-sized base and precious metals deposits in Latin America. The Company
intends to achieve this through the exploration for, and acquisition of,
projects that can be developed and placed into production. Coro's properties
include the Berta, Payen, El Desesperado, Llancahue, and Celeste copper
exploration properties located in Chile, and the advanced San Jorge copper-gold
project, in Argentina. Earlier this year, Coro sold its Chacay property to a
subsidiary of Teck for US$2,500,000 in cash plus a 1.5%NSR.
