Cornerstone and Thundermin to Resume Drilling on Little Deer Copper Deposit

MOUNT PEARL, NEWFOUNDLAND AND LABRADOR--(Marketwire - Sept. 15, 2009) - Cornerstone Capital Resources Inc. (TSX VENTURE:CGP) (FRANKFURT:GWN) (BERLIN:GWN) (PINK SHEETS:CTNXF) and 50% joint venture partner Thundermin Resources Inc. ("Thundermin") (THR:TSX) announce that they have approved a $600,000 diamond drilling program, comprising approximately 4,600 metres of drilling in 7 to 8 holes, for the Little Deer copper property located 10 km north of Springdale in north-central Newfoundland.

The primary purpose of this drill program, which follows 7,156 metres of drilling in 10 holes completed from March to July 2009, will be to expand the mineral resources outlined to date (see News Release 09-14, July 7, 2009) to the west and up dip. Priority targets include:

- 100 m west of hole LD-08-10A that intersected 2.2% Cu over a core length of 16.8 m;

- 150 m above and between holes LD-09-22 and LD-08-13 that intersected 3.8% Cu over 9.1 m and 1.3% Cu over 8.1 m, respectively; and

- 100 m above hole LD-00-12 that intersected 3.8% Cu over 10.7 m.

In addition, a shallow hole will be drilled below historical holes DP-66-01 and DP-66-02 that intersected 1.3% Zn and 1.3 g/t Au over 2.8 m, including 1.7% Zn and 3.0 g/t Au over 0.8 m, and 0.5% Zn and 0.2 g/t Au over 9.5 m, respectively. The purpose of this hole will be to determine the relationship of the zinc-gold mineralization to the main copper zone. It is anticipated that the drill program will commence this month and be completed in December.

Cornerstone and Thundermin also intend to undertake prospecting programs over two key areas within the large 276 claim, 6,630 hectare Little Deer property. A prospecting program undertaken in 2004 over claims held 100% by Cornerstone and Thundermin, led to the discovery of high grade gold in float and outcrop over a 1.5 km long, southwest trending area located 800 m southwest of the Little Deer copper deposit. Eleven of fifteen grab samples collected over this area returned gold values ranging from 0.3 to 22.7 g/t Au with the highest five samples assaying 22.7, 21.7, 19.6, 10.9, and 10.4 g/t Au. Additional prospecting, trenching and sampling are planned for this area in order to determine the extent and significance of this gold mineralization and what relationship, if any, it may have to the Little Deer deposit.

A 227 line km airborne VTEM electromagnetic and magnetic survey was completed in the summer of 2008 over the section of the Weyburn Investments Ltd. property that lies immediately east of the Little Deer and Whalesback copper deposits. The VTEM survey successfully identified five conductive trends within the southern portion of the claims which are considered to be priority targets for base metal and/or gold deposits. An initial program of prospecting and ground verification of these airborne conductors is also planned for this fall.

Mr. Andrew Hussey, P.Geo., Project Geologist and Lands Manager, Cornerstone Resources Inc., is the Q.P. that is responsible for supervising the drilling and exploration programs on the property for the purposes of NI 43-101. Mr. Hussey is also the Q.P. that has reviewed and approved the contents of this release.

Thundermin and Cornerstone 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 during 2009.
