Cornerstone and Altius Form Alliance to Explore for Copper in the Labrador Trough

MOUNT PEARL, NEWFOUNDLAND AND LABRADOR--(Marketwire - June 11, 2008) - Cornerstone Capital Resources Inc. (TSX VENTURE:CGP) (PINK SHEETS:CTNXF) (FRANKFURT:GWN) (BERLIN:GWN) and Altius Resources Inc. ("Altius") announce that they have signed a joint venture agreement to explore primarily for Sediment-hosted Stratiform Copper (SSC) deposits in the Labrador Trough of western Labrador and southeastern Quebec.

Agreement Summary

- The 50-50 Joint Venture will cover 51 mineral exploration licences totaling 1032 km2 in the province of Newfoundland and Labrador.

- Both companies contribute their respective mineral land holdings and have conjointly staked additional claims.

- Both companies will contribute equally to fund exploration programs.

- Primary exploration targets are Sediment-hosted Stratiform Copper (SSC) deposits analogous to those found in the prolific Zambian Copperbelt.

- First year program includes an airborne magnetics and radiometrics survey and a two month field program.

- Cornerstone is the project operator.

- Major partner being sought.

The property covers a 100 km strike length of favourable stratigraphy considered highly prospective for hosting SSC-type deposits.

The companies are soliciting expressions of interest from major mining companies as prospective joint venture partners to undertake exploration on this large, highly prospective and under-explored property. View map at http://www.cornerstoneresources.com/s/Labrador.asp?ReportID=305332.

The Labrador Trough (or New Quebec Orogen) represents a 1600 km long by 160 km wide linear fold belt that comprises predominantly meta-sedimentary and volcanic rocks originally deposited in an Early to Middle Proterozoic continental-rift environment, the ideal geological setting for SSC-type deposits. The Labrador Trough represents one of the least explored SSC opportunities within this type of environment in the world today. Numerous copper occurrences throughout the property support the geological model for SSC-type deposits and indicate the potential for discovery of new mineralization is high.

Cornerstone has been exploring for SSC-type deposits for several years and as such its technical team has developed considerable expertise in these geological environments. Cornerstone has generated several SSC-type projects of merit in Newfoundland and New Brunswick and been successful in attracting senior joint venture partners such as Noranda and Phelps Dodge to finance the exploration of these projects (Princess, Redcliff, Codroy and Dorchester). In particular, Phelps Dodge (Freeport McMoran) has entered into three separate joint venture/earn-in agreements on three individual SSC-type projects. Cornerstone will utilize this comprehensive experience to prioritize targets and to manage and operate the exploration program on behalf of the alliance.
