      12-09 - Cornerstone Announces Final Trenching Results and
      Proposed Phase 1 Drilling Program at La Fortuna Copper-Silver
      Project, Chile
=======================================================================

Mount Pearl, NL, Canada: Cornerstone Capital Resources Inc.
("Cornerstone") (TSXV-CGP) (F-GWN) (B-GWN) (OTC-CTNXF) today announced
the sampling results of three additional trenches and completion of the
surface exploration program at the La Fortuna copper-silver project
located in the Valpara�so Region of central Chile, approximately 100 km
north of Santiago. All technical data from the project has been
incorporated into a 3D model, and a Phase 1 drilling program has been
designed to test eight highly prospective targets. Results from initial
trenching and a general description of the exploration program were
announced on August 30, 2011 and February 22, 2012.

Maps showing the location of the La Fortuna project, geology and
updated exploration results and drill targets can be viewed at

Highlights

.. Trench TH15: 12.0 m grading 0.39% Cu and 0.5 g/t Ag
.. 3D model completed
.. Phase 1 drill program (18 holes totaling 5,500 m) proposed to test 8
priority targets

"The thorough exploration program carried out at La Fortuna confirms
the potential of this property to host significant manto-type copper
and silver mineralization. We are very pleased with the encouraging
results and the promising drill targets that have been developed" said
Brooke Macdonald, Cornerstone's President and CEO. "Consistent with our
prospect generator business model, Cornerstone is actively seeking a
joint venture partner to help advance exploration on this drill-ready
project".

Exploration program

The La Fortuna property covers an area of 2,900 hectares, measuring
approximately 10 km north-south by 3 km east-west. The project is
favourably located in an established mining district at relatively low
elevations (1200 to 1800 m above sea level), and is easily accessed by
existing roads. The property is partly contiguous with the Cerro Negro
copper-silver mine, a manto-type deposit immediately to the west which
combines open pit and underground operations and produces copper
cathodes via heap leach SX-EW and copper-silver concentrates via
flotation. The El Bronce epithermal gold-silver district is located 30
km to the north. The region is sparsely populated, and has a hot and
dry climate which is well-suited for leaching operations. Many surface
mineral occurrences have been worked by small scale miners in the past
but no drilling has ever been carried out at La Fortuna.

The surface exploration program carried out during the period April
2011 to April 2012 includes prospecting over the entire property,
geological and structural mapping and rock sampling (168 representative
chip samples), hand-dug trenching (19 trenches totaling 710.1 m, 348
channel samples), a 217 line km ground magnetic survey and a 39.8 line
km, deep penetrating (400 m) induced polarization (IP) survey.

Trenching

Results from trenches TH1 to TH7 were released on August 30, 2011 with
TH1 returning 19.5 m at 1.34% Cu and 58.0 g/t Ag. Results from Trenches
TH8 to TH14 were released on February 22, 2012 with TH8 returning 117.9
m at 0.19% Cu and 9.4 g/t Ag, including 52.4 m returning 0.33% Cu and
16.9 g/t Ag. Table 1 below provides assay results for the final three
trenches TH15A, TH15B and TH15C.

* The reported copper and silver intervals are apparent thicknesses due
to the early nature of the exploration program.


Significant copper and silver assay results were obtained in 2011 in
the northern two-thirds of the property, defining seven prospective
mineralized zones over a large area of approximately 18 km�.
Higher-grade mineralization is concentrated in, but not restricted to,
veins that are typically 1 to 2 m wide but occasionally up to 4 m,
emplaced within wider (up to 50 m) fault zones, often intruded by
andesitic porphyry dykes. A structural analysis defined two main
structural trends, with the most prominent orientation at N45 to N70
degrees and a second set, striking N320 degrees. Mineralization is also
present as disseminations in fractures and shear zones within halos to
the structures and within breccias over significant widths (up to 117.9
m in trench TH8). A statistical geochemical study indicates a high
correlation factor (0.63) between copper and silver mineralization. It
also shows a very high correlation factor (0.80) between As, Sb and Hg,
indicating the possible presence of a superimposed high level
epithermal system. Information collected thus far suggests that
mineralizing fluids migrated along steeply dipping structures and
metals were deposited within the structure and wall rocks and within
geochemically receptive, sub-horizontal, geological horizons and higher
porosity, brecciated rocks. The presence of intrusive rocks (stocks,
dykes, etc.) appears to be an important controlling factor for the
deposition of mineralization. Geological interpretation suggests that
geological Unit 4 (U4, on the geological map) could be the
stratigraphic equivalent of the Diablo Breccia unit hosting the
copper-silver mineralization at the neighbouring Cerro Negro Mine.

Drill target definition

Eight prospective drill targets were defined through the integration of
all datasets. The names and extent of the original target areas have
been revised slightly since the August 30, 2011 news release. Updated
target information (name and size) is shown on the maps linked to this
news release.

.. Vizcachas (V): The Vizcachas Fault is a NNW oriented, SW dipping,
important mineralized structure located in the western part of the
property. To the north, a few hundred metres outside of the property
boundary, copper and silver mineralization is mined by small scale
miners. At this location, mineralization is present as disseminated
bornite and chalcopyrite within greywacke and shale units in the
footwall of the Vizcachas Fault. This structure is present for more
than 2 km on the La Fortuna property. In the southern portion of the
fault, a well-defined and extensive (NE -- SW elongated, 400 to 800 m
wide by > 1200 m long) moderate IP chargeability anomaly is coincident
with the thick (> 200 m), porous, U6 breccia unit and the Vizcachas
Fault. Four drill holes (FP01, FP02, FP03 and FP04) totalling 1,350 m
are proposed to test this large target over a 900 m strike length. 

.. Loma Verde East (LVE): This target is located on the eastern
extension of the Loma Verde Fault, a N80 degrees oriented and steeply
dipping structure. Mapping and sampling at the Loma Verde Mine (third
party owner, small scale mining operation) to the west, suggest that
this fault is a major control for the mineralization hosted within the
greywacke (U3 and U5 units) and the U4 breccia unit. The Loma Verde
Fault extends for more than 600 m to the east and probably crosses the
contact with the north-south and fault-bounded andesitic sub-volcanic
unit. Trench TH2 dug across the structure returned 19.8 m at 1.34% Cu
and 58 g/t Ag. Four drill holes (FP05, FP06, FP07 and FP08) totalling
1,150 m are proposed to test the mineralized fault at depth, the U4
unit and a moderate to strong IP chargeability anomaly.

.. Loma Verde Southwest (LVSW): The U4 breccia unit hosts copper and
silver mineralization on this target located to the southwest of the
Loma Verde Mine. The breccia is dissected by a N45 degrees oriented
fault. The fault and breccia have been trenched and returned 117.9 m
grading 0.19% Cu and 9.4 g/t Ag, including 53.4 m grading 0.33% Cu and
16.9 g/t Ag. A weak IP chargeability anomaly is present at depth. This
target will be tested with two drill holes (FP09 and FP10) totalling
450 m.

.. Loma Verde West (LVW): This target corresponds to a mineralized, N60
degrees oriented, southeast dipping fault associated with a large
positive magnetic anomaly to the southeast, indicating a possible
intrusive body at depth. Trench TH14A tested the fault at surface and
returned 7.7 m grading 0.36% Cu and 11.6 g/t Ag and trench TH14B
returned 25.5 m grading 0.19% Cu and 6.2 g/t Ag. Two drill holes (FP011
and FP012) totalling 600 m are proposed to test the mineralized fault,
the magnetic anomaly, the U4 unit and a coincident moderate IP
chargeability anomaly at depth. 

.. Loma Verde Southeast (LVSE): Surface mineralization on this target is
associated with a N35 degrees oriented fault, intruded by magnetic,
andesitic porphyry dykes. The best surface results were obtained in
trench TH7 which returned 10.8 m grading 0.95% Cu and 17.6 g/t Ag, and
16.0 m grading 0.49% Cu and 9.6 g/t Ag from two different zones. Two
drill holes (FP013 and FP014) totalling 650 m are proposed to test this
target comprising the mineralized fault and dykes, U4 breccia unit and
coincident moderate IP chargeability anomaly at depth.

.. Quebrada Honda Central (QHC): One drill hole (FP015, 150 m) is
proposed to test surface copper mineralization (Trench TH12: 28.1 m
grading 0.19% Cu) associated with the Quebrada Honda Fault, which
separates the volcano-sedimentary units to the west from the andesitic
subvolcanic rocks to the east. A strong IP chargeability anomaly is
associated with this contact and could be coincident with the U4 unit
at depth.

.. North Zone (NZ): The North Fault located in the northwest corner of
the property, separates the volcano-sedimentary domain to the south
from a volcanic domain to the north. The fault strikes N140 degrees,
dips 50-60 degrees to the SW and is intruded by andesitic porphyry
dykes. The north volcanic sequence and the dykes are silicified,
argillized and affected by supergene leaching of the sulphides. The NW
part of the fault has an associated a magnetic high anomaly. The IP
survey indicates a strong and aerially extensive (1300 m by > 400 m)
chargeability anomaly to the SW of the fault. It is associated with the
lower units of the volcano-sedimentary package mapped on the property
and located in the hanging wall of the fault. Two drill holes (FP016
and FP017) totalling 750 m are proposed to test this target.

.. Quebrada Honda North (QHN): In the north central part of the property
the Quebrada Honda Fault is characterized by the presence of breccias,
quartz -- carbonate alteration and disseminations of pyrite,
chalcopyrite and malachite. One short drill hole (FP018, 150 m) is
proposed to test this target below trench TH 15A which returned 12 m
grading 0.39% Cu and 0.5 g/t Ag.

Sampling and assaying

All samples are delivered by Cornerstone employees for preparation at
Acme Analytical Laboratories (ACME) facility in Santiago, Chile. Rock
samples are prepared crushing 1 kg to 80% passing 2 mm (10 mesh),
splitting 250 g and pulverizing to 85% passing 0.075 mm (200 mesh)
(ACME code R200-250). Gold is assayed in Chile, using a 30 g split,
Fire Assay (FA) and AA or ICP-ES finish (ACME code G601). A 100g-plup
is shipped to ACME in Vancouver, Canada where samples are assayed for a
multi-element suite (ACME code 1DX2, 15g split, Aqua Regia digestion,
ICP-ES finish). All samples with results > 100 g/t Ag, >10,000 ppm Cu,
Pb or Zn are systematically and quantitatively re-assayed (ACME code
7AR, Aqua Regia Digestion, ICP-ES finish). All samples with results >
5,000 ppm Cu total are systematically re-assayed to determine leachable
copper (ACME code G9, Citric acid leach, Cu, 1 g/100 mL, AAS finish).

Quality assurance / Quality control (QA/QC)

ACME is an ISO 9001:2008 qualified assayer that performs and makes
available internal assaying controls. Certified blanks and standards
are systematically used as part of Cornerstone's QA/QC program, and are
inserted every 20 samples at La Fortuna.
