      11-28 - Cornerstone Reports 1.34% Copper and 58.0 g/t Silver over
      19.5 m in trenching at La Fortuna Copper-Silver Project, Chile
=======================================================================

Mount Pearl, NL, Canada: Cornerstone Capital Resources Inc.
("Cornerstone") (TSXV-CGP) (F-GWN) (B-GWN) (OTC-CTNXF) announced today
preliminary results for the ongoing exploration program at the La
Fortuna copper-silver project located in the Valpara�so Region of
central Chile, approximately 100 km north of Santiago. A map showing
the location of the La Fortuna project, as well as geology and
exploration results may be viewed at

Highlights

- Seven prospective mineralized zones distributed over a large area (18
km2) identified to date

- Of 163 rock samples collected during mapping and prospecting, 34
(19%) returned > 0.5% Cu, including 24 (14%) which returned > 1.0% Cu;
18 (10%) returned > 30 g/t Ag, including 5 (3%) which returned > 100
g/t Ag

- Trench TH1 returned 19.5 m at 1.34% Cu and 58.0 g/t Ag

- 78% of copper is soluble in samples (49) which returned > 0.5% Cu

- 200 line km ground magnetic survey completed; Induced Polarization
survey planned

- Project located immediately adjacent to the Cerro Negro copper-silver
mine and mill with connecting road infrastructure

Brooke Macdonald, Cornerstone's President commented: "We are very
pleased with the results obtained so far at La Fortuna. In only a few
months our geologists have identified significant mineralized zones
distributed over an extensive area. Ground magnetic and induced
polarization geophysical surveys will help to locate the stratigraphic
horizons where we believe sulfide replacement and manto-type
mineralization occur at depth. There are already some obvious drill
targets, and with further trenching and data integration, new targets
will be developed."

Assay results

Significant copper and silver assay results have been obtained in the
northern two-thirds of the property, with seven prospective mineralized
zones identified 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.
Mineralization is also present as disseminations in fracture/shear
zones and at the outer contact zone of intrusive rocks, over
significant widths (up to 19.5 m in trench TH1, see assay results
below). The structural zones are up to 50 m wide, and there is normally
a correlation between Cu and Ag contents.

A total of 163 rock samples (representative chip samples) were assayed
during the prospecting work. Of these, 63 samples returned > 0.1% Cu,
including 34 samples which returned > 0.5% Cu and 24 samples which
returned > 1% Cu. Eighteen (18) samples returned > 30 g/t Ag, including
5 samples which returned > 100 g/t Ag. Eight (8) samples are gold
anomalous (>0.1 g/t Au), including 3 samples which returned > 0.5 g/t
Au.

Including channel samples (160) from the trenching program, forty-nine
(49) samples which returned > 0.5% total copper (1.78% Cu arithmetical
average) were re-assayed for soluble copper (1.43% Cu arithmetical
average). These results indicate that 78% of the copper is soluble.

Exploration program

The La Fortuna property covers an area of approximately 2,900 hectares,
measuring 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.

An exploration program began in April with reconnaissance geological
mapping, prospecting and rock sampling. During this initial work phase,
geological units were defined, a structural study performed, and
altered and mineralized zones were mapped and sampled. Following the
reconnaissance work, data was integrated and prospective areas defined
for follow-up. Detailed mapping and hand-trenching were then initiated
and this work is ongoing.  Eleven (11) trenches totaling 532.7 meters
were dug and channel sampled. A total of 427 rock samples (167 rock
chips from prospecting and 260 trench channel samples) have been
collected so far on the project. Assay results are still pending for
the last 105 samples. A ground magnetic survey in excess of 200 line km
was recently completed by consulting firm, Santiago-based, Argali
Geofisica E.I.R.L. in the northern 2/3 portion of the property. This
geophysical data is currently being processed and will be used to
support the geological interpretation and to define the most
prospective areas to carry out an Induced Polarization (I.P.) survey in
the coming months. Further trenching and detailed geological mapping
are planned in areas where anomalous Cu-Ag-Au results have been
obtained thus far.

Trenching

Eleven (11) trenches were dug in the Guayacan (3), Loma Verde (1), Loma
Verde Sur (3), Quebrada Honda (1), Vizcachas (3) and Enjalmao (1) areas
for a total of 532.7 m. Assay results from trenches TH1 to TH7 shown
below in Table 1 indicate that mineralization is not restricted to the
veins and could extend significantly, as disseminations, into the wall
rocks.

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

The trenching program is ongoing and will be extended to areas where
veins, structures and disseminated mineralization were found during
prospecting work and that have not yet been properly evaluated.

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. One of
them was inserted every 20 samples at La Fortuna.

Qualified Person

Yvan Crepeau, M.Ba., P.Geo., General Manager of Minera Cornerstone
Chile Limitada (MCCL) and a qualified person in accordance with
National Instrument 43-101, is responsible for supervising the
exploration program at the La Fortuna project and has reviewed and
approved the information contained in this news release.

La Fortuna option agreement

Cornerstone, through its wholly-owned subsidiary, MCCL, has entered
into an agreement with a Chilean individual to acquire the La Fortuna
property. The agreement gives Cornerstone the right to acquire an
