      12-07 - Cornerstone announces further exploration programs on the
      Shyri property, Ecuador
=======================================================================

Mount Pearl, NL, Canada: Cornerstone Capital Resources Inc.
("Cornerstone") (TSXV-CGP) (F-GWN) (B-GWN) (OTC-CTNXF) today announced
that a US$1.7 million exploration program has been approved by its
joint venture partner, Intrepid Mines Limited ("Intrepid"),  for the
second quarter ("Q2") 2012 on the Shyri property located in Azuay
province in southern Ecuador. Intrepid is funding 100% of the program,
after completion of which it will have earned its initial 60% interest
in the property (see "Shyri Option Agreement" below).

Highlights:

.. The Q2 program includes airborne and ground geophysical surveys, soil
geochemistry surveys, prospecting, detailed geological and structural
mapping, and a Phase 3 drilling program totaling approximately 2,500
metres on high priority porphyry targets on the western portion of the
Gama prospect.

.. The Q2 program is part of a larger exploration program totaling
US$4.13 million proposed by Cornerstone for the remainder of 2012. The
remainder of the program (Q3 & Q4) is subject to approval by Intrepid
on a quarterly basis.

.. The overall program proposed for 2012 contemplates 4 drilling
programs totaling 8,500 metres to drill test targets on Gama, Vetas
Grandes and Ca�aribamba.

"We are extremely pleased that Intrepid has approved the proposed
second quarter 2012 exploration program at Shyri, which includes
significant airborne and ground surveys, as well as additional drilling
focused on porphyry targets at the Gama prospect" said Brooke
Macdonald, Cornerstone's President and CEO. "We're confident that this
year's planned work programs will result in the identification of new
epithermal and porphyry drill targets, which will be prioritized along
with those already identified."

2012 Shyri property exploration program

Since acquiring the Shyri property in 2005, Cornerstone and its
partners have successfully identified highly prospective areas through
systematic and detailed exploration programs. So far four prospects
have been identified - Gama, Vetas Grandes, Ca�aribamba and Yanasacha.
Most of the exploration work prior to the April 2008 Mining Moratorium
(MM) focused on the specific prospect areas and as a result, very
little exploration work has been carried out on the balance of the
concessions.

The 2012 exploration program is designed to further test the individual
prospects by drilling and to explore parts of the concessions where
only limited work was carried out. An overall work program proposal
totaling US$4.13 million is currently under review by Intrepid. This
proposal includes Phase 3 drilling at Gama and Phase 1 drilling
programs at the Vetas Grandes and Ca�aribamba prospects, as well as a
systematic appraisal of the potential of the ground surrounding the
prospects.

A detailed helicopter borne magnetic and radiometric survey totaling
approximately 2,500 line kilometres (km) is planned to cover the
southern part of the Shyri property (4 concessions including the Vetas
Grandes and Ca�aribamba prospects) and the Yanasacha prospect located
in the northeastern part of property (1 concession). A detailed
geological and structural analysis will be carried out on all prospects
including field mapping, drill core review where available and
reinterpretation of airborne and ground geophysical survey data.
Another round of drilling totaling 2,500 metres (m) is proposed during
the fourth quarter (Q4) on prospects showing the best potential to host
economic mineralization and to test new targets developed from the
ongoing programs. Individual work programs on each prospect area are
described below.

Gama prospect

The Gama prospect comprises an extensive zone of high sulphidation (HS)
epithermal alteration measuring a minimum of 8.5 km by 3 km.  The
alteration is strongly zoned and centered over two high level,
porphyry-type intrusions at the 3,500 m to 3,800 m elevations. Gama is
located 15 km to the west of Iamgold's Quimsacocha High Sulphidation
(HS) epithermal gold deposit, 15 km to the south of International
Minerals' Rio Blanco Low Sulphidation (LS) gold-silver deposit and 10
km to the southeast of the Chaucha porphyry copper-molybdenum deposit.

Two drilling programs totaling 4,279 m were completed during 2011.
Drilling results and interpretation were provided in Cornerstone News
Releases 11-17, 11-26 and 12-03, the latter of which also summarized
the Q1 2012 exploration program.

A 75 line km Induced Polarization (IP) geophysical survey is planned to
cover prospective ground defined by geology and geochemical surveys. A
detailed ground magnetic survey (731 line km) that was initiated in
late January will be extended to cover newly defined geochemical
anomalies. Some infill soil sampling is also planned to better define
geochemically anomalous areas.

All new data will be integrated with the current database and developed
into a 3D model. A Phase 3 drilling program (2,500 m) that will test
priority targets is expected to commence in June.

Vetas Grandes prospect

Cornerstone discovered the Vetas Grandes mineralization in 2005, 20 km
south of Gama. The prospect comprises multiple, ENE trending LS to
Intermediate Sulphidation (IS) epithermal quartz veins within a zone at
least 2 km long and 1.5 km wide. The geology is similar to the nearby
Rio Blanco gold-silver deposit. Veins are exposed over a vertical
relief of 300 m and show a range of gold values and geochemical
signatures. Bonanza grade material, with channel samples returning 53.4
g/t Au and 641 g/t Ag over 3.4 m, appears to be localized at vein
intersections and where veins outcrop around the 3,220 m elevation.  At
this level there is evidence of boiling accompanied by the highest gold
values in surface samples. The prospect and exploration results are
described in Cornerstone News Releases 06-06, 06-19, 06-25 and 07-04.

The Vetas Grandes prospect has been thoroughly explored and is now at
the drill-ready stage. A structural study will be carried out and all
data integrated into a 3D model. Defined drill targets will be tested
by a diamond drill program (2,500 m) during the third quarter (Q3) 2012
once all permits (Environmental License and Water Permit) are granted
by the authorities. A systematic prospecting program is also planned on
parts of the concessions that were not systematically explored in the
past, using data generated during the early days of the project and the
new airborne geophysical data.

Ca�aribamba prospect

The Ca�aribamba prospect represents an IS, disseminated and vein-type
gold-silver epithermal system hosted in a diatreme complex.
Geologically it appears to be analogous to large, diatreme-hosted gold
deposits in Rosia Montana, Romania and Kelian, Indonesia. The area has
a history of artisanal mining of high-grade veins over at least 300 m
of elevation and in the 1970's four short drill holes were completed on
one of the four recognized vein systems. Work by Cornerstone expanded
known mineralization another 500 m north with the discovery of the
Guabisay structure where a 4.5 m channel sample within a
fault-controlled breccia zone returned 32.2 g/t  Au.  Cornerstone also
completed extensive geological, geochemical and geophysical (IP and
magnetic) surveys in the area and outlined several high priority
targets unrelated to the known mineralized zones.

This prospect is located only 5 km southeast of Vetas Grandes and is at
the same drill-ready and permitting stages. As with the other
prospects, all previous and new exploration data will be integrated,
targets defined and drill tested (1,000 m) during Q3 2012. Prospecting
work will be carried out on the Shyri Oeste concession located to the
west and where prospective LS vein systems were identified in the past
but never followed up.

Yanasacha prospect

The Yanasacha prospect occurs in the northeast portion of the Shyri
property, approximately 9 km northeast of the Quimsacocha HS deposit,
and is the least explored of the four main prospects. It comprises two
distinct shallowly dipping, lithologically controlled silicic
alteration zones (or lithocaps) at 3,300 m and 3,500 m elevation. These
are associated with near-vertical silicic ribs that define feeders to
the lithocaps. Limited rock sampling has returned maximum values of 1.1
g/t Au and 14 g/t Ag from the silicic alteration. A soil survey over an
area of 1.6 km by 2.2 km has identified a 1.4 km by 1.5 km circular
zone defined by > 10 parts per billion (ppb) Au and contains 4
anomalies > 26 ppb Au (95th percentile) including 15 samples with > 50
ppb Au. Individual soil values returned up to 328 ppb Au.

Permitting is currently underway, and geological mapping and rock and
soil sampling are scheduled during Q4 2012.

Shyri Option Agreement

Intrepid Mines Limited ("Intrepid") is earning a 60% interest in the
Shyri gold-silver-copper property under an option agreement signed with
Cornerstone in January 2011. Under the terms of the Agreement, Intrepid
has the ability to earn an initial 60% interest in the property by
spending $US 6.0 million dollars over 5 years. Intrepid may earn an
additional 20% in specific project areas up to 5,000 hectares each.
Upon designation of a Project Area, Intrepid will make a $US 750,000
private placement in Cornerstone. To earn the additional interest,
Intrepid will complete a bankable feasibility study or incur
expenditures of $US 20 million, whichever comes first, and make a cash
payment to Cornerstone of up to $US 5.0 million based on the gold
equivalent ounces in the mineral reserve. There is no limit to the
number of Project Areas Intrepid may designate within the property and
each 'stand-alone' Project Area requires the same earn-in requirements
(see news release dated Oct 29, 2009). Cornerstone is the project
operator, and manages the exploration programs in close consultation
and planning with Intrepid.
