MOUNT PEARL, NEWFOUNDLAND AND LABRADOR--(Marketwire - July 25, 2008) - Cornerstone Capital Resources Inc. (TSX VENTURE: CGP.V) (PINK SHEETS: CTNXF.PK) (FRANKFURT: GWN.F) (BERLIN: GWN.BE) and 50% joint venture partner Thundermin Resources Inc. announce that they have intersected an interval of predominantly massive to semi-massive sulphide mineralization on the Little Deer property that assays 2.2% Cu over a core length of 16.8 m, including an interval of 3.9% Cu over 5.9 m. The true widths of these intervals have yet to be determined. The mineralized zone, which was intersected by deepening hole LD-08-10, contains three separate intervals comprising up to 80-90% pyrrhotite-chalcopyrite mineralization within moderately to intensely altered mafic volcanic rocks and is the westernmost intersection of copper mineralization to date in the Little Deer drilling program. (see Table 1 and Figure 1 - http://cornerstoneresources.com/s/Image.asp?i=maps/properties_nfld_littledeerlongsec.jpg).

Holes LD-08-09 and LD-08-10 were drilled previously in the western portion of the Little Deer property to test the projection of a surface DEEPEM geophysical conductor which is coincident with high grade copper mineralization in the eastern portion of the property. Borehole Pulse EM geophysical surveys completed on both of these holes revealed strong, 20 channel, off-hole responses at the bottom of both holes suggesting the presence of a conductive source beyond the end of each hole. The recent deepening of hole LD-08-10 has resulted in the discovery of a zone containing massive to semi-massive pyrrhotite-chalcopyrite mineralization at a vertical depth of approximately 700 m. This intersection, which is approximately 475 m west of the intersection in historical hole LD-00-12 that assayed 3.8% Cu over a core length of 10.8 m, is the westernmost and deepest intersection on the property and contains the most massive sulphide mineralization intersected to date. High-grade copper mineralization has now been intersected on the Little Deer property over a strike length of approximately 900 m, between a vertical depth of 250 m to 700 m. Also, the surface DEEPEM conductor that is coincident with the copper mineralization is interpreted to extend at least another 300 m southwest of the intersection in hole LD-08-10A.

Hole LD-07-01A was deepened to test the westward extension of the recently released intersection in hole LD-98-07D that assayed 2.2% Cu over a core length of 74 m, including an interval of 6.5% Cu over 8.6 m (news release dated June 17, 2008). This hole, which is located approximately 100 m to the west, intersected several high-grade, but relatively narrow, chalcopyrite-pyrrhotite stringers and minor disseminated sphalerite within moderately to strongly altered mafic volcanics. The best intervals include 6.0% Cu over 2.2 m and 6.0% Cu over 0.5 m. Hole LD-08-11 was drilled approximately 50 m west of hole LD-98-07D. This hole also intersected minor chalcopyrite and sphalerite mineralization within moderately to intensely altered mafic volcanics but failed to intersect significant copper mineralization. Assays are awaited for this hole. Additional drilling is required in this area to determine the extent and orientation of the high-grade copper mineralization intersected in hole LD-98-07D.

Thundermin and Cornerstone have approved an approximately $1,000,000 exploration budget for the remainder of 2008. This budget will provide for an estimated 6,500 m of diamond drilling, borehole Pulse EM surveys, 3-D modeling of all diamond drill holes and reconnaissance follow-up on any conductors that may have been detected during a recently completed 225 km VTEM airborne EM survey covering prospective ground lying immediately east of the Little Deer and Whalesback copper deposits. Diamond drilling during the remainder of 2008 will focus on the delineation of the high-grade copper mineralization intersected in holes LD-08-10A, LD-98-07D, historical hole LD-00-12 and the deepening of hole LD-08-09 with the view of being able to undertake a preliminary resource calculation for the property by the end of the year.

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 and June 17, 2008 and on Thundermin's and Cornerstone'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. Terry Brace, V.P. Exploration for Cornerstone, is the qualified person that has reviewed and approved the contents of this release. All 2007 and 2008 drill holes are NQ in size. Specific gravity, 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 the above referenced diamond drilling program.
