Cornerstone Provides Exploration Update

Cornerstone Capital Resources Inc. ("Cornerstone") (TSX VENTURE:CGP)
(FRANKFUR:GWN) (BERLIN:GWN) (OTCBB:CTNXF) today provided an update on its active
exploration projects in Ecuador, Chile and Canada.


Brooke Macdonald, Cornerstone's President and CEO said "Despite the challenging
market conditions for exploration and mining companies, we have remained active
on our key projects. This can largely be attributed to the success of our
prospect generator business model under which our partners fund the majority of
the exploration programs and we retain a significant minority participating
interest. Upcoming exploration drilling on several projects, including Shyri and
Cascabel in Ecuador, and La Fortuna in Chile, provide opportunities for large
new discoveries, while planned definition drilling at the Little Deer copper
project in Newfoundland will help advance that project towards the
pre-feasibility stage".


ECUADOR

Shyri

The 300 km2 Shyri property is located in Azuay Province in southern Ecuador, and
is targeting porphyry gold-copper and epithermal gold-silver deposits. The
property is subject to an option and joint venture agreement with Intrepid Mines
Limited which is earning an initial 60% interest by spending US$6 million over
five years.


Exploration programs over the past two years have focused primarily on porphyry
gold-copper targets in the Gama prospect area located in the northwest part of
the property. During 2011, two phases of diamond drilling (totaling 4,279 m in
13 holes) were completed on the Boqueron target area. The drilling confirmed the
existence of porphyry intrusions at depth with associated alteration and
gold-copper mineralization. The best result was returned from hole GAD-11-002
which intersected 45 metres (m) at 0.71 g/t gold and 0.18% copper within a
broader mineralized zone that returned 0.41 g/t gold and 0.13% copper over 101
m.


During 2012, exploration work has included detailed geological mapping, soil
geochemistry and ground geophysical surveys (magnetics and induced polarization)
focused on the Satoshuaycu porphyry target area which is located approximately 2
km west of Boqueron and at 300-500 m lower elevation. The Satoshuaycu target
shows characteristics of a very large (4 km by 1 km) mineralized porphyry system
including: 1) outcropping porphyry intrusions; 2) associated hydrothermal
alteration zone(s); 3) coincident gold-copper-molybdenum soil geochemistry
anomalies; 4) magnetic high; and 5) associated induced polarization
chargeability anomalies. New porphyry and epithermal style targets are currently
being tested with the induced polarization survey.


In September 2012, Dr. Jeffrey Hedenquist spent 6 days visiting the property,
reviewing data and results from surface exploration work and drilling programs,
and participating in the design of future exploration programs. Dr. Hedenquist,
a world-renowned expert on epithermal and porphyry deposits, initially visited
and reported on the Shyri property in 2006 and 2007, and his continued
involvement in the project provides tremendous support in developing deposit
models for this very large and complex system.


On September 27, a phase 3 drilling program (2,500 m in 5 holes) designed to
test the Satoshuaycu porphyry target was announced. The program is expected to
commence in mid-October, and results will be announced as they become available.


Meanwhile, we continue to seek permits required for phase 1 drill programs at
the Vetas Grandes and Canaribamba prospects located in the southern part of the
Shyri property. Comprehensive exploration programs have been carried out on
these prospects over the past several years, and both prospects are drill-ready.


Cascabel

The 50 km2 Cascabel property is located in Imbabura Province in northern
Ecuador, approximately 120 km north of Ecuador's capital city, Quito, and 20 km
south of the Colombian border. The project is targeting porphyry gold-copper
deposits, and is subject to an option and joint venture agreement with SolGold
Plc which is earning an initial 65% interest by spending US$7.8 million over
four years.


During 2012, exploration work has included geological mapping and prospecting,
stream sediment geochemistry and panning surveys, and rock chip and detailed
channel sampling of outcrops in stream valleys. Two main areas of outcropping
porphyry gold-copper mineralization have been identified at Quebrada Moran
("Moran") and Quebrada Alpala ("Alpala"). These areas are 1.5 km apart and are
interpreted to represent portions of a single large porphyry gold-copper system.
The target area shows characteristics of a large (2 km by 1 km) mineralized
porphyry system including: 1) outcropping areas of porphyry hydrothermal
alteration and mineralization, including mineralized "B" veins with chalcopyrite
and magnetite; 2) areas of sheeted B veins with up to 4.9 g/t gold and 1.3%
copper; and 3) significant areas of gold and copper enrichment with
representative rock chip samples returning greater than 1 g/t gold and greater
than 1% copper.


In mid-August, SolGold's Chief Geologist - Dr. Bruce Rohrlach, visited the
Cascabel project and added significantly to developing a better understanding of
the property geology and deposit model(s). Dr. Rohrlach brings considerable
technical expertise on porphyry and epithermal deposits, having spent 25 years
working on similar deposits in Australia, the Philippines, Papua New Guinea and
throughout South America.


Ongoing work includes detailed geological mapping and channel sampling of
outcropping porphyry mineralization, systematic soil sampling over the main
target area (5 km by 3 km) and a property wide helicopter-borne magnetic and
radiometric survey. Once all results have been compiled and interpreted, targets
will be prioritized for a phase 1 drilling program which is expected to begin in
Q1 2013.


Bella Maria

The 10.4 km2 Bella Maria property is located in El Oro Province in southwest
Ecuador, approximately 50 km southeast of the provincial capital city of
Machala. The project is targeting porphyry gold-copper deposits and is
100%-owned by Cornerstone.


During 2012, exploration work has included geological mapping and prospecting,
stream sediment geochemistry and panning surveys, and soil and rock sampling.
The property is underlain by a series of granodiorite and quartz diorite
porphyries that intrude metamorphosed volcanic and sedimentary rocks of the El
Oro Metamorphic Complex. Highlights of work completed to date include:




--  Four mineral prospects identified: 1) Pavas Breccia; 2) Central Breccia;
    3) Southeast Breccia; and 4) Vega Rivera Porphyry 
--  Stream sediment geochemistry survey (44 samples collected): 26 samples
    returned greater than 0.1 g/t gold, including 11 that returned greater
    than  1 g/t gold. 
--  Panned stream sediment sampling (96 samples collected): 59 sampling
    sites showed gold grains, including 28 sites with greater than 10 gold
    grains. 
--  Rock sampling (262 samples collected): 97 samples returned greater than 
    0.1 g/t gold including 29 sampled that returned greater than 1.0 g/t
    gold; 166 samples returned greater than 0.01% copper including 13
    samples that returned greater than 0.1% copper. 
--  Soil sampling (725 samples collected by Cornerstone and a predecessor
    company): define a large (3.5 km by 1.5 km) coincident gold- and copper-
    in-soil anomaly in the central part of the property.



Although at a very early stage of exploration, mineralization styles at Bella
Maria appear similar to those at Odin Mining and Exploration Limited's "Greater
Cangrejos" project, which is contiguous to the south. Diamond drilling at
Greater Cangrejos has returned encouraging results including 192 m at 1.5 g/t
gold and 137.3 m at 1.27 g/t gold in a mineralized porphyry at the Trinchera /
Paloma target, and 6 m at 8.96 g/t gold and 2 m at 14.2 g/t gold in at the
Casique target, where higher grade mineralization is hosted in structures and
hydrothermal breccia zones.


Cornerstone is actively seeking a joint venture partner to advance exploration
at Bella Maria.


La Encrucijada

The 80.85 km2 La Encrucijada property, which was acquired in March 2011 from an
Ecuadorian exploration company, is located in south-central Ecuador in Loja
province, 100 km south of the city of Cuenca. The property lies between two
major northeast (NE) trending regional faults and within a NE oriented
epithermal belt which hosts significant copper-gold porphyry and gold-silver
epithermal prospects.


Geological crews carried out prospecting work over the entire project area to
verify the earlier exploration results and to extend the reconnaissance
geological mapping and sampling program over the balance of the project area
that had not been previously explored. This work by Cornerstone confirmed the
potential of the property to host significant epithermal high-sulphidation (HS)
gold-silver mineralization at the Marcoloma prospect and structurally controlled
intermediate sulphidation (IS) gold-silver and base metal mineralization at the
Alumbre prospect. A new epithermal HS alteration zone was identified at
Potrerillos. Ridge and spur soil sampling on the Alumbre sector on the northern
part of the property defines a gold-in-soil anomaly measuring 1,000 m by 500 m
that is open in one direction. A second 500 m by 400 m gold anomalous area has
been defined to the south. 


CHILE

La Fortuna

The 29 km2 La Fortuna property is located in the Valparaiso Region of central
Chile, approximately 100 km north of Santiago. The project is favourably located
in an established mining district at relatively low elevations (1,200 to 1,800 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.


Cornerstone has the right to acquire a 100% interest in the La Fortuna property
by incurring exploration expenditures of CAN$3.0 million and making cash
payments totalling CAN$600,000 over a 4-year period ($70,000 at signing, $30,000
at end of year 1 and $500,000 at end of year 4 if the option is exercised). The
acquisition is subject to a 1.5% Net Smelter Royalty ("NSR"), and to advance
payments of the NSR on each anniversary following the date the option is
exercised. Cornerstone has a right of first refusal to purchase the NSR if the
holder decides to sell it.


Over the past year and a half, Cornerstone has carried out an exhaustive
exploration program at La Fortuna which has included geological mapping and
prospecting, ground geophysical surveys (detailed magnetics and induced
polarization), and hand trenching and channel sampling. The trenching program
was highlighted by trench #1, where continuous channel sampling returned 1.34%
copper and 58.0 g/t silver over 19.5 m. All of the exploration data has been
integrated into a 3-dimensional model and 8 drill target areas have been
defined. A phase 1 drill program comprising 5,400 m in 18 holes has been
proposed, and will be carried out subject to financing or partner funding.


Cornerstone has signed confidentiality agreements with several companies who
have expressed interest in partnering on the project.


CANADA

Little Deer

The Little Deer property is located in north-central Newfoundland, approximately
10 km north of the town of Springdale. The property hosts the past-producing
Little Deer and Whalesback VMS copper deposits. The property is subject to a
50/50 joint venture agreement with Thundermin Resources Inc., the Little Deer
Joint Venture ("LDJV"), with Thundermin being the project operator.


The LDJV has carried out various exploration programs over the past five years,
most of which have been focused on the Little Deer Copper Deposit ("Little
Deer") and comprised primarily of diamond drilling. Since 2007 the LDJV has
completed approximately 48,800 m of diamond drilling in 82 holes on Little Deer
resulting in National Instrument 43-101 ("NI 43-101") compliant Indicated
Resources of 1,911,000 tonnes grading 2.37% Cu (99.8 million pounds of copper)
and Inferred Resources of 3,748,000 tonnes grading 2.13% Cu (175.0 million
pounds of copper). The LDJV has also completed metallurgical testing and a
Preliminary Economic Analysis ("PEA") for Little Deer, both of which produced
positive results.


During 2011 and early 2012, the LDJV completed a compilation of historical drill
hole and mine data for the Whalesback Copper Deposit ("Whalesback") which was
followed up with a 14 hole, 6,198 m drill program. A subsequent NI 43-101
compliant resource estimate for Whalesback resulted in Indicated Resources of
797,000 tonnes grading 1.67% Cu (29.3 million pounds of copper) and Inferred
Resources of 443,000 tonnes grading 1.57% Cu (15.3 million pounds of copper).
Also during 2012, bore hole Pulse-EM geophysical surveys were completed on six
of the new Whalesback drill holes and surface Pulse-EM geophysical surveys were
completed over several untested airborne conductors located approximately 3 km
east of the deposits. Currently the data is being reviewed by our geophysical
consultants with the interpretation report pending. This work is expected to
direct future drilling at Whalesback and possible drill testing of the airborne
conductors.


Further work in Q4 2012, subject to financing, includes a definition diamond
drilling program at Little Deer which will consist of approximately 7,000 m of
drilling in 9-10 holes in the eastern, higher grade, portion of the deposit.
This work would be followed by additional definition drilling in 2013 in other
areas of the deposit. This work is designed to upgrade the Inferred Resources to
the Indicated Resource category in order that a pre-feasibility study can be
undertaken on the deposit.


Cape Ray

The Cape Ray property is located in southwest Newfoundland approximately 25 km
northeast of the town of Port aux Basques. The property hosts two undeveloped
gold-silver deposits - the 51 Zone of the historic Cape Ray gold deposit and the
Windowglass Hill deposit.


On July 18, Cornerstone announced the results of a NI 43-101 mineral resources
estimate which was carried out by Mercator Geological Services Limited on the 51
Zone and Windowglass Hill deposits. Highlights include:




--  51 Zone - Inferred resources of 530,000 tonnes grading 6.10 g/t gold and
    15.86 g/t silver containing 103,943 ounces of gold and 270,253 ounces of
    silver (2.5 g/t gold cut-off) 
--  Windowglass Hill - Inferred resources of 1,810,000 tonnes grading 1.77
    g/t gold and 11.28 g/t silver containing 103,001 ounces of gold and
    656,415 ounces of silver (0.5 g/t gold cut-off) 
--  Mineralization is relatively shallow at a maximum of 270 metres
    vertically below surface for the 51 Zone and 140 metres for Windowglass
    Hill 
--  Opportunities exist to upgrade and expand the mineral resources



The NI 43-101 Technical Report in support of the mineral resource estimate was
filed on SEDAR on August 31. On September 20, Cornerstone announced that it had
signed a binding letter of intent ("LOI") with Benton Resources Inc. outlining
the terms of an option/joint venture agreement for the Cape Ray property. Under
the terms of the LOI, Benton has the ability to earn an initial 70% interest in
the property by spending CAN$2 million on exploration, and making payments of
CAN$125,000 and 155,000 shares over 4 years. Benton can earn an additional 5%
(taking their interest to 75%) by incurring an additional CAN$1 million in
exploration expenditures at its sole election but such election must be made
within a period not exceeding 18 months from the date that Benton's interest
vests at 70%.


Currently Benton, in collaboration with Cornerstone, is planning upcoming
exploration programs for the project. Both partners feel there is excellent
potential to expand existing resources, as well as for new discoveries along the
Cape Ray Fault Zone.
