      10-21 - Cornerstone and Thundermin announce a 20% increase in
      inferred mineral resources for the Little Deer Copper Deposit,
      Springdale area, Newfoundland
=======================================================================

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) are pleased to announce the
results of an updated National Instrument 43-101 ("NI 43-101")
compliant mineral resource estimate for the Little Deer Copper Deposit
(the "Deposit") which is located approximately 10 km north of
Springdale in north-central Newfoundland. The mineral resource estimate
was completed by Scott Wilson Roscoe Postle Associates Inc. ("Scott
Wilson RPA") of Toronto, Ontario, Cornerstone's and Thundermin's
independent resource estimate consultants.

Scott Wilson RPA estimates that the Deposit contains Indicated Mineral
Resources of 1,150,500 tonnes at an average grade of 2.8% Cu and
Inferred Mineral Resources of 2,335,500 tonnes at an average grade of
2.1% Cu (see Table 1 and Figures 1 and 2). 

Table 1: Scott Wilson RPA Mineral Resource Estimate, September 30, 2010

Resource Classification/Zone      Tonnes      Cu %
Indicated Mineral Resources
Little Deer Zone                 1,150,500     2.8
Inferred Mineral Resources
Little Deer Zone                 1,227,300     2.2
Footwall Zone                    1,108,200     1.9
Total Inferred Resources         2,335,500     2.1

Notes:
1.  CIM definitions were followed for Mineral Resources.
2.  Mineral Resources are estimated at a cut-off grade of 1.0% Cu.
Tonnages are rounded.
3.  Mineral Resources are estimated using an average long-term copper
price of $US 3.25 per pound and a $US/$CDN exchange rate of 0.90.
4.  A minimum mining width of 2.0 metres was used.
5.  No Mineral Reserves are present on the Little Deer property at this
time.

The updated Little Deer mineral resource estimate was prepared by Scott
Wilson RPA using a database containing 113 current and historical drill
holes, 91 (48,814 m) of which were drilled from surface between 1961
and July 2010 and 22 (3,008 m) of which were drilled from underground
during 1968. Of the 91 surface holes, Cornerstone and Thundermin have
drilled 35,742 m in 57 holes, including all wedge holes and hole
deepenings.

The updated mineral resource estimate includes results from an
additional 26 drill holes that were completed on the Deposit following
the release of the initial mineral resource estimate on July 7, 2009.

These holes include new holes from surface as well as wedge cuts and
deepenings of pre-existing holes. Some of the 26 holes were infill
holes designed to provide fresh core samples for on-going metallurgical
test work at SGS Lakefield Research ("Lakefield").  The remaining holes
were drilled to confirm the continuity of the mineralization between
widely-spaced holes and to expand, mainly at depth, the mineral
resources that had been outlined to date in the Deposit.
 
Based on Diamond drilling results to date, the Deposit is now
interpreted to consist of two main copper-bearing zones, the Little
Deer Zone and the Footwall Zone with the Footwall Zone occurring mainly
west of, and from 50 to 75 m below, the Little Deer Zone (see Figures 1
and 2). A number of additional copper-bearing zones have also been
intersected in the footwall of these two zones by the drilling
completed to date, but their extent and significance are unknown at the
present time.

To date, the Deposit has been intersected over a strike length of
approximately 1,050 m and to a vertical depth of approximately 1,000 m.
The overall Deposit remains open along strike to the east and west, up
dip and at depth and the potential exists for the discovery of
additional mineral resources in all areas. Furthermore, the potential
for additional mineralization is also believed to be high in the
central gap between the Little Deer and Footwall Zones (see Figures 1
and 2).

Borehole Pulse EM geophysical surveys are being undertaken on 5 to 6 of
the recently completed deep drill holes prior to the commencement of a
new drill program on the Deposit. Information gained from these surveys
will assist with targeting of new drill holes in these areas.

Qualified Persons

The updated mineral resource estimate was prepared by Mr. Reno
Pressacco, M.Sc. (A), P.Geo., Senior Geologist for Scott Wilson RPA of
Toronto, Ontario. Mr. Pressacco is an independent Qualified Person
("Q.P.") in accordance with NI 43-101. Mr. Pressacco has reviewed the
contents of this news release for accuracy. A NI 43-101 compliant
Letter Report entitled "Mineral Resource Update for the Little Deer
Project" dated September 30, 2010 has been filed with Cornerstone and
Thundermin and is available on each company's website. 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 Little Deer property for the purposes of NI 43-101. Mr.
Hussey has also reviewed the contents of this news release for
accuracy.

Infrastructure

The Little Deer Copper Deposit is well situated to take advantage of
Newfoundland's developed infrastructure. The Deposit is located
approximately 16 km from the Trans Canada Highway and it is easily
accessible by a 10 km network of paved and gravel roads north of
Springdale, where there is an available skilled mining workforce. The
site is approximately 8 km from a major power transmission grid and
there is a plentiful supply of fresh water in the area. The historical
Whalesback tailings impoundment site, which may offer opportunities for
refurbishment and storage of additional tailings, is located only 1.2
km north of the Deposit. There is also reasonably good access to a deep
water port for any future shipment of copper concentrates. The Duck
Pond base metal concentrator, which is owned by Teck Resources Inc., is
located approximately 165 km by paved and gravel road from the Little
Deer site, 66 km of which is on a secondary paved road and 70 km of
which is along the Trans Canada Highway.

Metallurgy

Metallurgical test work on fresh core samples collected during the
latest Diamond drilling campaign is on-going and nearing completion at
Lakefield. This work is focusing on expected 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 will be
reported shortly. 

Little Deer Joint Venture

Cornerstone and Thundermin, the operator, 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 Cornerstone's and Thundermin's respective websites
and on SEDAR.

Junior Exploration Assistance Program

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.
