      12-11 - Cornerstone announces receipt of authorization to resume
      activities and exploration results for the Bella Maria project,
      Ecuador
=======================================================================

Mount Pearl, NL, Canada: Cornerstone Capital Resources Inc.
("Cornerstone") (TSXV-CGP) (F-GWN) (B-GWN) (OTC-CTNXF) announced today
that the Company has been authorized by the Ministry of Non-Renewable
Natural Resources - Ministerio de Recursos Naturales No Renovables
(MRNNR) to resume the exploration activities corresponding to the
initial exploration phase (prior to drilling) on Cornerstone's Bella
Maria porphyry gold-copper project located in El Oro province in
southern Ecuador. Results of exploration work by previous owners and
Cornerstone have been compiled and are summarized below. Although at an
early stage, initial results indicate that the property has excellent
potential for hosting significant gold and copper mineralization.

Highlights

.. Stream sediment sampling: 44 samples collected, 26 with > 0.1 g/t
(100 ppb) Au, including 11 > 1 g/t (1000 ppb) Au. 96 Heavy Mineral
Concentrate (HMC) samples collected: 59 sampling sites showing gold
grains, including 28 sites with > 10 gold grains.
.. Rock sampling: 262 samples collected, 97 with > 0.1 g/t Au and 29 >
1.0 g/t Au; 166 samples > 0.01% (100 ppm) Cu and 13 > 0.1% Cu.
.. Soil sampling: 725 samples collected by Cornerstone and predecessor
company define extensive (3.5 km by 1.5 km) gold and copper in-soil
anomalies in the central part of the property.
.. Four mineralized prospects identified.
.. Multiple stream sediment, rock and soil anomalies yet to be followed
up.

Brooke Macdonald, Cornerstone's President & CEO stated "We are very
pleased to have received the authorization from the MRNNR to pursue our
exploration activities on the Bella Maria property. Although at an
early exploration stage, the project area shows excellent potential for
hosting significant gold and copper mineralization. Stream sediment
samples collected across the property are exceptionally anomalous in
gold, and a large coincident gold- and copper-in-soil anomaly
accompanied by porphyry style mineralization has been identified in the
central part of the property. Following our prospect generator business
model we will look for potential partners to aggressively explore this
property in the coming months".

Bella Maria property
The Bella Maria property is located in El Oro province along the
western foothills of the Andes, 30 km southeast of the port city of
Machala at elevations ranging from 100 m to 600 m above sea level.
Access is good via paved roads from either Guayaquil, a major port city
located approximately 200 km by road to the northwest of the property,
or from Cuenca to the northeast. The area is characterized by tropical
climate and vegetation. A series of maps showing the location of the
Bella Maria project, regional and local geology, and geochemical
results may be viewed at
http://www.cornerstoneresources.com/s/Ecuador.asp?ReportID=136196.

Regional Geology
The project area is underlain by Paleozoic age metamorphic rocks
including quartz biotite orthogneisses, quartz biotite schist and
chlorite schist (La Victoria Formation) which form part of the El Oro
Metamorphic Complex. The metamorphic rocks are intruded by Tertiary age
granodiorite (Biron Batholith) and quartz diorite. The Oligocene age
Saraguro Formation (andesitic to rhyolitic flows and pyroclatics) lies
to the east. The intrusive rocks are cut by Miocene age porphyry stocks
which host low-grade gold-copper (< 1 g/t Au and < 0.5% Cu)
mineralization. Higher grade gold-copper mineralization occurs in
hydrothermal breccias adjacent to porphyry bodies. Epithermal gold
deposits in the region are commonly associated with the porphyry
systems.

Property history and compilation work
The Bella Maria area was historically worked for gold by artisanal
miners. Odin Mining and Exploration Ltd. ("Odin") was active on its
Biron alluvial gold mine located about 10 km west of the Bella Maria
concession from 1987 to 1995. Newmont Overseas Exploration Limited, a
subsidiary of Newmont Mining Corporation ("Newmont") operated a joint
venture with Odin from 1994 until 2001 to try to locate the source of
the alluvial gold, at which time they withdrew and Odin continued
exploration. The survey work carried out focused on the
Trinchera-Paloma gold-copper porphyry and the Cacique breccia target
areas, part of Odin's Cangrejos project which is contiguous with the
Bella Maria property to the south.
 
The Bella Maria concession was acquired by Sierra Minera S.A.
("Sierramin") in 2001 to cover a mineralized breccia related to
porphyry intrusions, at which time it was optioned to Bear Creek Mining
Corporation ("Bear Creek"). Survey work completed during 2004 describes
structurally controlled quartz-tourmaline-pyrite breccias with the
development of silica flooding, potassic and sericitic alteration and
quartz veinlets. The initial soil survey that was recommended by Bear
Creek in 2005 consisted of two blocks each measuring approximately 1.2
km2 with one block centered on the Bella Maria breccia and the other
centered on the gold anomalous defined by Bear Creek on the west side
of the concession. Anomalous gold occurs in soil on both grids
associated with the known mineralization, as well as other anomalous
values (0.05 to 0.5 g/t Au) which require further follow-up.

The concession was acquired by Cornerstone in late 2005 and only
limited prospecting work was carried out prior to the April 2008 Mining
Moratorium in Ecuador.

Property geology and mineralization
Reconnaissance geological mapping and data compilation from previous
surveys indicate that the property is located within the northern
contact zone between the Biron Batholith to the south and Paleozoic
age, basement rocks (El Oro Metamorphic Complex). This contact zone is
characterized by multiphase intrusions varying from granitic to
dioritic in composition intruding metasedimentary and metavolcanic rock
units (schist and orthogneiss). Foliations strike WSW to WNW (N250�E to
N290�E) and generally dip to the north. Faults and minor structures
generally strike NE and NW.

Four mineralized prospects have been identified so far on the property.
Assay results for each of the prospects are described in the table
below.

Pavas Breccia (PB): Hydrothermal breccia developed within a quartz
diorite intrusive. Matrix of the breccia is silicified and tourmaline
rich. Late quartz veins and veinlets are present. Eight (8) rock
samples were collected (4 locally derived floats and 4 outcrops).

Vega Rivera Porphyry (VRP):  Located in the central part of the
property along the Q. Cardenas stream. At this location, gold and
copper mineralization is associated with stockworks of quartz veinlets
developed within silicified and potassicly altered granodiorite and
quartz-feldspar porphyry units. Pyrite, chalcopyrite and occasionally
some molybdenite are present as fine disseminations, associated with
quartz veinlets and as coatings along fractures. Potassic and silicic
alteration is present over a 500 m distance on outcrops along Q.
Cardenas stream. Twelve (12) representative grab and rock chip samples
were collected by Cornerstone on this target.

Central Breccia (CB):  Hydrothermal breccia located in the south
central part of the property at the intersection of NE-SW, N-S and E-W
oriented faults. The breccia is composed of angular fragments of
metamorphic and intrusive rocks within a silicified matrix containing
1-5% pyrite and traces of chalcopyrite, bornite, covellite and
chalcocite. Sulphides are disseminated and associated with late quartz
and quartz-tourmaline veinlets. Eighty-six (86) rock samples (76%
channel and panel samples and 24% grab samples) were collected on this
target.

Southeast Breccia (SEB): This target area is located in the
southeastern part of the property at the contact between a
granodiorite-diorite and schist units. At this location rocks are
highly silicified, fractured and oxidized (manganese and iron oxides
after pyrite and chalcopyrite) and cut by quartz veins and quartz
veinlets stockworks. Results: Fifty-six (56) channel and panel rock
samples were collected on this target.
Balance of property: An additional 100 samples (mostly grab and some
chip samples) were collected on the property, outside of the four
prospect areas during the prospecting work.

Regional Airborne Magnetic Survey 
A regional magnetic survey was flown in 2000 by Canada-based Sial
Geosciences Inc. on behalf of the British Geological Survey. The survey
is coarse with a line spacing of 1 km; however, regional structures are
evident. A strong east-west magnetic anomaly (low) is situated along
the southern boundary of the Bella Maria concession. Secondary
northeast trending magnetic lineaments are also apparent, trending in
the same direction as structures and mineralized trends defined on
Odin's Cangrejos (name changed to Greater Cangrejos) project south of
Bella Maria. The positive magnetic anomaly south of Bella Maria
corresponds in part to an altered porphyry intrusion.

Airborne magnetic surveys confirm east-west and northeast-southwest
striking structures defined during the prospecting and reconnaissance
geological mapping programs.

Topography and Structure
The porphyry stocks and breccias may be related to a 15 km by 17 km
caldera structure defined by two concentric ring features evident in
topographic maps. Mineralized zones within the ring complex appear to
be controlled by major SW-NE trending structures.

Stream sediment survey
A stream sediment survey was carried out. Forty-four (44) samples were
collected over the property and sent to the laboratory for assaying the
standard minus 80 mesh fraction. Ninety-six (96) sites were sampled and
pan concentrated to check for the presence, size and shape of gold
grains. The minus 80 mesh fraction of stream sediments is extremely
anomalous in gold throughout the Bella Maria concession: 22 samples
assayed > 100 ppb (0.1 g/t) Au, including 11 samples (25%) with > 1000
ppb (1 g/t) Au. Most streams contain abundant visible gold in panned
concentrates. Other metal values are low to moderately elevated for Cu
(8.0 to 160.0 ppm Cu) and Mo (0.2 to 4.3 ppm Mo). There is a
correlation of copper and molybdenum with the higher gold values.

Soil sampling survey
Cornerstone's ridge top soil lines (227 samples) results show an
extensive gold anomaly that is continuous between the two grids sampled
by previous owner Sierramin-Bear Creek (498 samples) throughout the
south central part of the concession. Copper results and to a lesser
degree, molybdenum results, are coincident with the area of elevated
gold. The sample locations and results for gold and copper can be seen
on the accompanying maps.

Exploration targets and future work
There are two identified target types on the Bella Maria property: 1)
high tonnage, low grade porphyry style gold - copper deposits and, 2)
lower tonnage and higher grade, structurally controlled gold (copper)
deposits (hydrothermal breccia bodies, stockworks, fault controlled
shatter zones) which are peripheral to the mineralized porphyry bodies.

A systematic and detailed exploration program is required to further
evaluate the four known prospects, as well as the stream sediment and
soil anomalies that have been identified.

Future work proposed for the Bella Maria concession includes expansion
of the soil grids to cover the entire property, a detailed ground
magnetic survey and an induced polarization ("IP") survey, which will
be followed by detailed geological mapping and trenching. Targets will
then be prioritized for drill testing.

Assaying, Quality assurance / Quality control (QA/QC)

All samples collected by Cornerstone were delivered to and prepared by
the ACME preparation laboratory in Cuenca and assayed by the
ACME-Vancouver laboratory (www.acmelab.com) using the following
procedures:

Rock samples: Two preparation schemes were used for rocks at Bella
Maria: 1) ACME preparation code R150 (crush 1 kg to 80% passing 10
mesh, spilt 250 g and pulverize to 85% passing 150 mesh); assayed for
gold  and 2) ACME preparation code R200-250 crush 1 kg to 80% passing
10 mesh, spilt 250 g and pulverize to 85% passing 200 mesh), assayed
for gold and multi-elements (ACME code 1DX2, Aqua Regia, ICP-MS finish,
15 g.) and (AC code G601, F.A., 30 g., AA finish) in some cases. Over
limits results for gold were systematically re-assayed (ACME code G601;
F.A., 30g.; AA finish).

Stream sediment samples: ACME preparation code SS80, assayed for gold
(ACME code 3B01, F.A., 30 g.) and multi-elements (ACME code 1DX2, Aqua
Regia, ICP-MS finish, 15 g.).

Soil samples: ACME preparation code SS80, assayed for gold and
multi-elements (ACME code 1DX2, Aqua Regia, ICP-MS finish, 15 g.).
Limited technical information is available from the early soil sampling
by Sierramin with regards to sample preparation and assaying techniques
used by the laboratory. Samples appear to have been assayed for gold
(F.a., 30 g.) and an ICP suite of elements.

ACME is an ISO 9001:2008 qualified assayer that performs and makes
available internal assaying controls. Certified blanks and standards
are systematically inserted with samples as part of Cornerstone's QA/QC
program.
