Cornerstone and Thundermin Provide Update on the Little Deer Copper Property, Newfoundland

MOUNT PEARL, NEWFOUNDLAND AND LABRADOR--(Marketwire - Feb. 25, 2009) - Cornerstone Capital Resources Inc. (TSX VENTURE:CGP) (PINK SHEETS:CTNXF) (FRANKFURT:GWN) (BERLIN:GWN) and 50% joint venture partner Thundermin Resources Inc. ("Thundermin") announce that a $900,000 exploration program consisting of approximately 5,800 m of diamond drilling and borehole Pulse EM surveys has been approved for the first half of 2009 for the Little Deer copper property which is located approximately 10 km north of Springdale in north-central Newfoundland.

The last two holes of the 2008 drilling campaign, LD-08-16 and LD-08-17, also intersected significant copper mineralization (Table 1 and Figure 1 - see link: http://cornerstoneresources.com/i/maps/properties_nfld_littledeerlongsec.jpg). Hole LD-08-16 intersected 1.3% Cu over a core length of 31.1 m, including 1.5% Cu over 18.8 m and 4.0% Cu over 3.4 m at a vertical depth of 828 m. This hole intersected the mineralized zone approximately 120 m below hole LD-08-10A, which intersected 2.2% Cu over 16.8 m, including 3.9% Cu over 5.9 m. These are the westernmost holes drilled to date on the property and the copper mineralization in this area remains open to the east and west and at depth. Hole LD-08-17 (Figure 1) intersected three separate mineralized zones grading 1.8% Cu over 6.6 m, 1.0% Cu over 11.3 m and 2.2% Cu over 3.5 m at a vertical depth of 539 m. This hole is approximately 60 m west of historical hole LD-00-12 that intersected 3.8% Cu over 10.7 m. All mineralized widths are core lengths; true thicknesses have yet to be determined.

The copper mineralization on the Little Deer property has now been intersected over a strike length of approximately 1,050 m and to a vertical depth of approximately 800 m.

A review of the underground diamond drilling undertaken on the Little Deer property by British Newfoundland Exploration Company ("BRINEX") in 1967-68 has been completed to the extent possible from known historical mine records (as stored in the archives of the Department of Natural Resources, St. John's, NL). The holes of primary significance to the joint venture are listed in Table 2, in the notes to Table 2 and shown on Figure 1. These intercepts are historical results which are believed to be indicative of the grade and thickness of the mineralization in this area but which have not been verified due to the lack of original sample material, lab reports and in-hole survey data.

Notes:

- The majority of these holes were drilled from a cross-cut from the
Whalesback Mine and the intersections are true widths or approach true
widths.

- Holes 1 (2.4% Cu/4.9 m), 2 (1.1% Cu/3.4 m), 3 (2.4% Cu/2.7 m), 4 (0.7%
Cu/1.5 m), 5 (2.4% Cu/2.7 m), 6 (1.3% Cu/35.4 m) and 7 (3.4% Cu/3.1 m)
shown on Figure 1: - the hole locations and copper intersections for these
holes were recovered from an historical longitudinal section but attempts
to recover the actual drill logs from the historical files have been
unsuccessful.


Most of the BRINEX holes were drilled from a cross-cut from the past-producing Whalesback Mine, which is located on joint venture property approximately 1,000 m to the north of the Little Deer copper deposit. These holes intersected the copper-bearing zone from a vertical elevation of -210 m to -380 m and the recorded intersections represent close to true widths. Of significance, is the excellent continuity of copper grades in this area of the deposit along with the potential for increased tonnages in the area of holes 8-146, 147, 150, 151, 161 and 170. In addition, the intersections in holes 8-173, 174, 175 and 180 suggest that the copper mineralization extends farther to the east than previously thought.

Priority targets for the current drill program, which will commence immediately and run through the end of June 2009, include the area around holes LD-98-07D (2.2% Cu over a core length of 74.0 m) and LD-08-15 (2.7% Cu over 46.6 m); the area east and west of hole LD-08-10A (2.2% Cu over 16.8 m); a new and previously untested, VTEM airborne conductor situated along the northwest shore of Little Deer Pond; and on the - 400 m elevation below historical holes LD-66-136 (2.0% Cu over 6.1 m) and LD-66-122 (1.6% Cu over 2.6 m) (Figure 1).

The thick zone of copper mineralization intersected in holes LD-98-07D and LD-08-15 appears to occur to the north of the main zone mineralization where it remains open down dip (plunge?) and to the east. The exact relationship of this mineralization to the main zone mineralization is unknown at the present time as only a few holes have been drilled this far north at this elevation. Likewise, the copper mineralization intersected in hole LD-08-10A remains open to the east, west and at depth. Both of these areas offer opportunities to expand the mineralized zone and require additional drilling to further define the extent and significance of the copper mineralization.

A geophysical conductor was identified on adjacent 100 m spaced flight lines along the northwest side of Little Deer Pond during a VTEM electromagnetic and magnetic survey flown in the fall of 2008. This conductor, which occurs at a vertical depth of approximately 350 m exhibits good conductivity and has not been drill tested. The conductor may represent a new zone of copper-bearing sulphide mineralization or it could be a faulted or folded extension of the Little Deer mineralization.

The Little Deer property also appears to have potential at shallower depths. A couple of wide-spaced holes on the 400 m elevation are planned to further evaluate the area immediately west of the main area of drilling. Here there are two 1966 holes which intersected copper mineralization that require follow-up.

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 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 and November 26, 2008 and 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 2008 drill holes 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.

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.
