      10-16 - Cornerstone and Thundermin intersect 2.3% Cu over 18.0 m,
      including 4.2% Cu over 5.5 m, in deepest intersection to date at
      Little Deer
=======================================================================

Mount Pearl, NL, Canada:   Cornerstone Capital Resources Inc.
(TSXV-CGP) (F-GWN) (B-GWN) (OTC-CTNXF) and 50% joint venture partner
Thundermin Resources Inc. ("Thundermin") (THR:TSX) announce that they
have intersected 2.3% Cu over a core length of 18.0 m, including 4.2%
Cu over 5.5 m, approximately 992 m below surface on the Little Deer
Copper Deposit ("Deposit") located approximately 10 km north of
Springdale in north-central Newfoundland (see Table 1 and Figure 1).
This intersection, which is the deepest significant copper
mineralization intersected to date in the Deposit, suggests that there
is good potential to increase tonnages at depth at Little Deer. The
potential to increase tonnes at depth, however, is conjectural in
nature and additional drilling will be required to define the true
tonnage potential of the Deposit.

Notes:
*  Reported intervals are core lengths. The true thicknesses of the
various copper intersections are highly variable due to the stringer
nature of the mineralization. Management, however, believes that the
true thicknesses of the drill intercepts average approximately 70% -
75% of core lengths.

uz  Relatively narrow but generally high grade upper zone also
intersected in previously reported holes LD-10-32, LD-10-32A, and
LD-08-09B.

Hole LD-10-34 -- no significant values.

The current $1,500,000 diamond drilling program, which commenced on
February 3, 2010 and finished on June 29, 2010, consisted of 10,649 m
of NQ drilling in eight surface holes, three hole deepenings and four
wedge holes. Assay results for ten of these holes were presented in
Cornerstone and Thundermin news releases dated April 13 and April 29.
The results for the final five holes of the program are set out in
Table 1 and on Figure 1:
http://www.cornerstoneresources.com/i/maps/properties_nfld_littledeerlongsec.jpg. The primary goals of this drill program were to increase
the mineral resources outlined to date in the Deposit (see Mineral
Resource Estimate below) by an additional two to three million tonnes
at generally comparable copper grades, and to obtain fresh core samples
for metallurgical testing at SGS Lakefield Research ("Lakefield"). A
potential increase in the current mineral resource is conceptual in
nature and it is uncertain whether further exploration will result in
an expansion of this mineral resource.

Holes LD-10-35, LD-10-36, LD-10-37 and LD-10-38 were drilled to confirm
and expand the resource potential in the western portion of the Deposit
where previously announced, wide-spaced holes LD-08-16, LD-08-16A,
LD-08-16B, LD-08-09B and LD-10-32A intersected substantial thicknesses
of copper mineralization within wide zones of intense chlorite
alteration (see Table 1 and Figure 1). In addition, previously
announced hole LD-10-32 intersected an extensive, locally copper
bearing, chlorite alteration zone from approximately 922 to 1,142 m
below surface before the hole was abandoned due to drilling
difficulties.

The most significant of the new drill holes, LD-10-37, intersected 2.3%
Cu over a core length of 18.0 m, including 4.2% Cu over 5.5 m,
approximately 992 m below surface (see Figure 1). This intersection is
approximately 50 m below and 115 m west of hole LD-10-32A, which
intersected 2.1% Cu over 19.6 m, including 4.6% Cu over 5.9 m and 14.5%
Cu over 1.5 m, and approximately 60 m east and 145 m below hole
LD-08-16A, which intersected 1.2% Cu over 9.4 m and 1.5% Cu over 23.3
m, including 3.1% Cu over 6.2 m and 1.9% Cu over 15.8 m. Hole LD-10-37
also intersected wide zones of lower grade copper mineralization near
the bottom of the hole that assayed 1.1% Cu over 13.0 m and 1.3% Cu
over 9.9 m. The presence of substantial thicknesses of copper
mineralization within wide zones of intense chlorite alteration
suggests that there is a good possibility that the Deposit may extend
to depth in this area.

An upper, relatively narrow, but generally high grade copper zone has
been intersected in the western portion of the Deposit over a strike
length of approximately 200 m and over a vertical depth of
approximately 150 m. Intersections in this zone include 5.8% Cu over
1.8 m, 7.9% Cu over 0.3 m, 2.4% Cu over 5.2 m and 1.9% Cu over 4.6 m in
new holes LD-10-37, LD-10-38, LD-10-36 and LD-10-35, respectively (see
Table 1), and 8.8% Cu over 1.8 m, 5.5% Cu over 0.8 m and 0.8% Cu over
8.8 m in previously announced holes LD-10-32A, LD-08-09B and LD-10-32,
respectively. The total extent and significance of this zone is unknown
at the present time.

Hole LD-10-34 failed to intersect any significant sulphide
mineralization approximately 933 m below surface in the central portion
of the Deposit. A borehole Pulse EM survey is planned for this hole to
determine if there are any nearby sulphides that were missed by the
drilling.

Further diamond drilling to expand the mineral resources within the
Deposit and to upgrade known resources from the Inferred to the
Indicated mineral resource category will await the receipt of final
results from the updated mineral resource estimate and the
metallurgical test work.

Cornerstone and Thundermin would like to acknowledge the financial
support received from the Junior Exploration Assistance ("JEA") program
of the Province of Newfoundland and Labrador in carrying out a portion
of their work on the Little Deer property.

Mineral Resource Estimate

On July 7, 2009, Cornerstone and Thundermin reported a National
Instrument 43-101 ("NI 43-101") mineral resource estimate for the
Deposit comprising Indicated Resources of 1,087,000 tonnes at an
average grade of 2.9% Cu and Inferred Resources of 1,950,000 tonnes at
an average grade of 2.3% Cu. The mineral resource estimate was prepared
by Mr. Reno Pressacco, M.Sc.(A), P.Geo., then Senior Geologist for
Micon International Limited of Toronto, Ontario, an independent
Qualified Person ("Q.P.") in accordance with NI 43-101. A NI 43-101
Technical Report supporting the mineral resource estimate was filed on
SEDAR on August 20, 2009.

An updated NI 43-101 compliant mineral resource estimate, to include
results from 26 holes drilled subsequent to May 2009, will commence
shortly and take approximately three weeks to complete.

Metallurgy

Metallurgical test work is on-going at Lakefield on fresh core samples
collected during the recent diamond drilling campaign. This work is
focusing on determining copper recoveries, copper concentrate grades,
reagent consumption, power usage for grinding and the environmental
characteristics of any tailings products. Initial results suggest that
a very simple metallurgical process will be required to recover the
majority of the copper from the Little Deer sulphides. Final results
from the metallurgical test work are expected near the end of August
and will be reported when received. 

Little Deer Joint Venture

Thundermin, the operator, and Cornerstone have the option, on a 50/50
basis to earn a 100% interest in the Little Deer Copper Deposit and
adjacent property from Weyburn Investments Ltd. Thundermin, under its
joint venture agreement with Cornerstone, has the right to increase its
interest in the Little Deer property to 75% by completing a feasibility
study and by arranging 100% of the necessary bank financing required to
place the property into commercial production. Details on the Deposit
and the terms of the agreement with Weyburn can be found in numerous
news releases and on Thundermin's and Cornerstone's respective websites
and on SEDAR.

Qualified Person

Mr. Andrew Hussey, P.Geo., Project Geologist and Lands Manager,
Cornerstone Resources Inc., is the Q.P. responsible for supervising the
drilling program on the property for the purposes of NI 43-101. Mr.
Hussey has also reviewed the contents of this news release for
accuracy. All holes drilled by Cornerstone and Thundermin are NQ in
size. Specific gravity measurements, rock quality designations and
photographic logging of significant mineralized intersections are
performed systematically prior to assaying. The core is logged and the
mineralized sections, where appropriate, are sawn in half at a core
logging facility in Springdale. Half of the core is submitted for
analyses to Eastern Analytical Limited, an independent and qualified
assayer located in Springdale, and the remaining half of the core is
kept for future reference. Blanks, duplicates and standards are
routinely used as part of the assay procedures.
