- Diamond Drilling has commenced at Cornerstone's Flagship
      Shyri Gold-Copper Property in Ecuador
=======================================================================

Mount Pearl, NL, Canada: Cornerstone Capital Resources Inc. (TSXV-CGP)
(F-GWN) (B-GWN) (OTC-CTNXF) announced today that all permits have been
received and drilling has begun on Cornerstone's Gama Prospect, located
in the NW portion of the Company's flagship Shyri Gold-Copper Property
in southern Ecuador. This drilling is part of a first phase diamond
drilling program comprising approximately 2,900 m of drilling in 11
holes on seven drill targets.

Yvan Crepeau, MBa., P.Geo, President of Cornerstone Ecuador S.A. (CESA)
said; "I believe that all the drill targets on Gama have excellent
potential. For logistical reasons we are starting in the southern part
of the area at target F, and then moving northward." A map showing the
drill hole locations can be viewed at;

Drill Program
Cornerstone and its Shyri joint venture partner Intrepid Mines Limited
("Intrepid") (ASX-IAU, TSXV-IAU) have approved a Phase One 2,900 metre
diamond drilling program comprising 11 holes over various targets
identified on the basis of surface geochemistry, detailed geology,
magnetics, and 3-D interpretation of Induced Polarization (IP)
geophysical data.

The primary purpose of the current drill program is to drill test both
high sulphidation gold systems, comparable to the nearby 3.4Moz
Quimsacocha gold deposit, and porphyry copper-gold systems. The targets
have not been previously drilled.

The drill program will test the 7 targets over an area of 3 x 2
kilometers.

.. Target B is a coincident surface copper-gold-molybdenum geochemical
anomaly with a well-defined annular magnetic signature, and IP
chargeability and resistivity anomalies. The target model is a porphyry
system with areas of high sulphidation overprint;

.. Target C is a coincident silver-gold-mercury geochemical anomaly
possibly representing a high level epithermal system;

.. Target D is a coincident surface copper-gold-molybdenum geochemical
anomaly and IP chargeability anomaly that may represent a porphyry
system;

.. Target E is a coincident surface copper-gold-molybdenum geochemical
anomaly, IP chargeability anomaly, and geology that may represent the
upper zones of a porphyry system;

.. Target F is a coincident surface copper-gold-molybdenum geochemical
anomaly with encouraging geology suggesting a porphyry environment. The
IP geophysical coverage does not extend over this southern-most target
area;

.. One initial drill hole is proposed to test the mineralized Ermita
Breccia. Rock chips returned up to 5.7g/t gold from the breccia that is
interpreted to source a high sulphidation system at depth.

.. One drill hole has been planned to test an interpreted flat lying
high sulphidation system approximately 500m to the south of the Ermita
Breccia.

The approved exploration program includes sufficient scope to test
other targets that may emerge as a consequence of the results obtained
during the planned drilling, including geophysical targets that are
located to the north of Target B.

The Shyri Property is the subject of an Option Agreement with partner
Intrepid Mines Limited. As previously announced, Intrepid has the
option to acquire an initial 60% interest in Cornerstone's Shyri
Property which is located in southern Ecuador, approximately 350km
south of Quito and 150km north of the border with Peru. Under the terms
of the Agreement, Intrepid has the ability to earn an initial 60%
interest in the Shyri Property by spending $US 6.0 million dollars over
5 years, with a firm commitment of $US 1.0 million in the first year.
Intrepid will have the further right to earn an additional 20% interest
in a specific area of the Shyri property of up to 5,000 hectares
defined as a Project Area. 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 operator of the exploration program. Technical teams
from Cornerstone and Intrepid have worked closely together to define
the current suite of drill targets and to plan the ongoing regional
exploration program within the broader Shyri Property area.

Yvan Crepeau, MBa., P.Geo, President of Cornerstone Ecuador S.A. (CESA)
and a qualified person in accordance with National Instrument 43-101,
has reviewed and approved the technical information contained in this
new release.

Rare Earth on the first anniversary date, and exploration work
commitments during year 2 total $100,000.
