Thundermin and Cornerstone intersect 2.5% Cu over 5.5 m at the Little Deer deposit

Mount Pearl, NL, Canada - October 31, 2007:   Cornerstone Capital Resources Inc. (TSXV-CGP) (F-GWN) (B-GWN) (OTC-CTNFN) and 50% joint venture partner Thundermin Resources Inc. (TSX-THR) announce that they have intersected sulphide mineralization grading 1.24% Cu over 25.5 m, including a higher grade interval of 2.5% Cu over 5.5 m, at an approximate vertical depth of -625 m on the Little Deer copper deposit (see Table 1 below). This intersection is approximately 110 m deeper than any historical intersection within the Little Deer deposit and demonstrates there is good continuity of high grade copper mineralization below and along strike from areas that were mined during the 1970s.

Based on widely spaced drilling, comprising 14 Diamond drill holes, the Little Deer deposit is interpreted to form a semi-continuous sheet of mineralization, starting from a vertical depth of  -250 m, extending to a depth of -625 m, over a horizontal distance of approximately 500 m.  The current Diamond drilling program comprising approximately 5,300 m of drilling in 8 to 9 holes is designed to extend the mineralization both at depth and along strike of the deposit.

To date, 3,098 m of drilling in five holes has been completed. LD-07-01 was collared to intersect the Little Deer mineralized horizon at the -550 m elevation approximately midway between historical holes LD-00-12 and LD-98-07 (see Figure 2 accompanying News Release dated May 1, 2007). Hole LD-00-12 is the deepest westerly hole drilled on the property to date. Hole LD-07-01 intersected two, narrow, high grade copper intervals that assayed 8.90% Cu over 0.1 m and 3.20% Cu over 0.6 m. These zones are interpreted to be the upper edge of the copper mineralization in this area of the deposit. Additional drilling will be required in this area to further define the extent of the copper mineralization in holes LD-00-12 and LD-98-07.

Hole LD-07-02 intersected a 50.4 m zone of altered volcanics containing variable amounts of pyrite-pyrrhotite-chalcopyrite stringer mineralization. A 25.5 m interval within this zone assayed 1.24% Cu, including 5.5 m of semi-massive pyrrhotite-chalcopyrite-pyrite from 644.5 to 650.0 that assays 2.5% Cu and 6.0 m of stringer sulphides from 664.0 to 670.0 that assays 1.75% Cu.  The intersection in hole LD-07-02 is very significant in that it occurs approximately 110 m below historical hole LD-98-04 that assayed 4.3% Cu over 9.6 m and demonstrates that the Little Deer copper deposit in this area remains open at depth below -625 m.

Hole LD-07-03 was collared to intersect the mineralized horizon at the -550 m elevation approximately 75 m west and slightly deeper than historical hole LD-98-04. Hole LD-07-03 was lost at 768 m due to drilling problems. This hole has been lined with PVC pipe to accommodate a future borehole Pulse EM survey.

Hole LD-07-04 was collared to intersect the mineralized horizon approximately 50 m below historical hole LD-98-06 which assayed 1.1% Cu over 16.9 m. This hole was abandoned at 422 m due to excessive deviation.

Hole LD-07-05 was collared to intersect the mineralized horizon at the -460 m elevation between historical holes LD-98-03 and LD-98-08 which assayed 3.1% Cu over 12.9 m and 1.6% Cu over 38.7 m respectively. This 2007 hole intersected a 73 m interval of intermediate volcanic rocks from 456 to 529 m, containing variable amounts of disseminated and stringer sulphide mineralization similar in character to that intersected in LD-07-02. Included is a zone of semi-massive sulphide mineralization from 516.4 to 519.25 m. Assays for the mineralized intervals are pending.

Hole LD-07-06 was collared to intersect the mineralized horizon approximately 100 m below hole LD-07-05 on the -575 m elevation between historical hole LD-98-04 and current hole LD-07-02. This hole is in progress at 200 m depth.

Cornerstone and Thundermin have the option, on a 50/50 basis with Thundermin as operator, to earn a 100% interest in the Little Deer copper deposit and adjacent property from Weyburn Investments Ltd. ("Weyburn"). Details of the terms of the agreement with Weyburn and the results of historical exploration programs undertaken on the Little Deer copper deposit are contained in news releases issued by Cornerstone and Thundermin dated May 1, June 21 and July 10, 2007. This information can also be found on Cornerstone's and Thundermin's respective websites at www.cornerstoneresources.com and www.thundermin.com.

Andrew Hussey, PGeo., Project Geologist and Lands Manager, Cornerstone Resources Inc., is responsible for supervising the drilling program for the purposes of National Instrument 43-101. All 2007 drill holes are NQ in size. Specific gravity, rock quality determinations and photographic logging of significant mineralized intersections are systematically performed 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, Newfoundland. The remaining half of the core is kept for future reference. Blanks, duplicates and standards are routinely used as part of the assay procedures.

This press release was prepared by Andrew Hussey, PGeo, and Bruce Mitton, PGeo, Exploration Manager Canada for Cornerstone who are Qualified Persons as per National Instrument 43-101.

On Behalf of the Board,
Glen H. McKay
President & CEO
