Cornerstone and Thundermin Intersect 3.8% Cu Over 9.1 Metres on the Little Deer Deposit

MOUNT PEARL, NEWFOUNDLAND AND LABRADOR--(Marketwire - June 16, 2009) - Cornerstone Capital Resources Inc. (TSX VENTURE:CGP) (FRANKFURT:GWN) (BERLIN:GWN) (PINK SHEETS:CTNXF) and 50% joint venture partner Thundermin Resources Inc. ("Thundermin") announce that they have intersected 3.8% Cu over a core length of 9.1 m in hole LD-09-22 on the Little Deer Copper Deposit ( the "Deposit"). In addition, wedge hole LD-08-16A intersected variable amounts of copper mineralization over a core length of 99 m within strongly altered mafic volcanic in the western portion of the Deposit. The best intervals within this zone include 1.9% Cu over a core length of 15.8 m, including 2.9% Cu over 5.7 m, 1.5% Cu over 23.3 m, including 3.1% Cu over 6.2 m and 1.2% Cu over 9.4 m (Table 1 and Figure 1 -http://www.cornerstoneresources.com/i/maps/properties_nfld_littledeerlongsec.jpg). To date, the copper mineralization in the Little Deer Deposit has been intersected over a strike length of approximately 1,050 m and to a vertical depth of approximately 895 m. The Deposit remains open to the east, west and at depth.

The current diamond drilling program is part of a $Cdn 900,000 exploration program consisting of approximately 5,800 m of drilling that was announced on February 25, 2009 for the first half of 2009. Approximately 4,160 m of drilling in six holes have been completed to date. The current drill program is on-going and is expected to be finished near the end of June. As announced on May 12, 2009, Micon International Limited ("Micon") is preparing a National Instrument 43-101 compliant mineral resource estimate for the Deposit based on all drill hole data available up to and including wedge hole LD-08-16A. It is anticipated that Micon will complete this resource estimate early in the third quarter of 2009.

The copper-rich sulphide intersection in hole LD-09-22 which occurs in the western portion of the Deposit at a vertical depth of approximately 625 m, consists of disseminated, stringer, semi-massive and massive sulphides containing variable amounts of chalcopyrite, pyrrhotite and pyrite within strongly altered mafic volcanic rocks. This intersection occurs approximately 110 m east and 90 m above the intersection in hole LD-08-10A that graded 2.2% Cu over 16.8 m, including 3.9% Cu over 5.9 m (Figure 1).

Hole LD-08-16A intersected variable amounts of chalcopyrite, pyrrhotite and pyrite within a 99 m wide zone of strongly altered mafic volcanic rocks (Table 1 and Figure 1). The intensity and magnitude of chlorite alteration and the amount of copper mineralization appears to increase at depth in this area of the Deposit. The lower portion of the intersection in LD-08-16A occurs at a vertical depth of approximately 895 m and is the deepest intersection to date within the Deposit.

Hole LD-09-23, which is currently drilling, is collared to intersect the main copper-bearing zone approximately 175 m east of the intercept in LD-08-10A at a vertical depth of approximately 725 m (Figure 1).

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 Little Deer copper deposit and the terms of the agreement with Weyburn can be found in news releases dated May 1, June 21, July 9, October 30, December 11, 2007 and January 24, April 9, May 15, June 6, June 17, July 25, November 26, 2008, February 25, 2009 and May 12, 2009 posted on Cornerstone's and Thundermin's respective websites and on SEDAR.

Mr. Andrew Hussey, P.Geo., Project Geologist and Lands Manager, Cornerstone Resources Inc., is the qualified person that is responsible for supervising the drilling program on the property for the purposes of National Instrument 43-101. Mr. Hussey is also the qualified person that has reviewed and approved the contents of this release. All holes drilled by Thundermin and Cornerstone are NQ in size. Specific gravity measurements, rock quality determinations 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.

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.
