Cornerstone Notified by Vale Exploration Canada Inc. of Planned Diamond Drilling Program on the Red Cliff Copper Property in Newfoundland

MOUNT PEARL, NEWFOUNDLAND--(Marketwire - Sept. 27, 2010) - Cornerstone Capital Resources Inc. ("Cornerstone") (TSX VENTURE:CGP) (PINK SHEETS:CTNXF) (FRANKFURT:GWN) (BERLIN:GWN) is pleased to announce that it has been notified by Vale Exploration Canada Inc. ("VEC"), a wholly-owned subsidiary of Vale S.A. (NYSE-VALE) ("Vale"), that it will commence a 1,500 metre diamond drilling program on the Red Cliff copper property in mid-October. As previously announced (see news release dated May 04, 2010), VEC has the option to acquire a 60% interest in Cornerstone's Red Cliff and Deer Harbour properties which are located on the Bonavista Peninsula in eastern Newfoundland. VEC is the operator of the exploration programs during the option period in consultation with Cornerstone. The properties are targeting sediment-hosted stratiform copper (SSC) deposits similar to those of the prolific Central African Copperbelt, also of Late Neoproterozoic age.

Up to ten (10) drill holes ranging in length from 100 m to 250 m are planned to test the prospective Blue Point Horizon in three separate areas: 1) North of Duntara (6 holes, 850 m); 2) South of Duntara (1 hole, 200 m); and 3) east of Swibbs Cove Pond (3 holes, 450 m). Previous drill testing of the Blue Point Horizon in 2001 returned significant copper grades and thicknesses including 0.8% Cu and 7.7 g/t Ag over 9.69 m in hole RC-01-01 and 1.0% Cu and 12.1 g/t Ag over 14.25 m in hole RC-01-02.

Glen McKay, Cornerstone's President & CEO, commented "We are delighted with Vale's decision to further evaluate the potential of the Blue Point Horizon. Previous drilling by Cornerstone has encountered both economic grade and thickness for this deposit type and demonstrated the potential for bulk tonnage copper deposits in the Red Cliff project area."

Logistically, the Red Cliff property is very well located. The provincial capital of St. John's is situated only 270 road km to the east, and the property is located directly on tidewater, has good road access and is in close proximity to power and water supplies. The Government of Newfoundland and Labrador is strongly supportive of mineral exploration and responsible mine development, and local residents are receptive to new developments and eager to support economic growth.

This press release was prepared by Terry Brace, P.Geo., Cornerstone's VP Exploration and a Qualified Person in accordance with National Instrument 43-101. Exploration work on the Red Cliff project is being carried out under the supervision of Cameron Bowie, P.Geo., VEC's Principal Geologist for North American Exploration and a Qualified Person in accordance with National Instrument 43-101.
