Cornerstone Capital Resources Inc.: Clarification of August 29, 2007 News Release

MOUNT PEARL, NEWFOUNDLAND--(Marketwire - Aug. 30, 2007) - Cornerstone Capital Resources Inc. (TSX VENTURE:CGP) (FRANKFURT:GWN) (BERLIN:GWN) (PINK SHEETS:CTNXF) wishes to clarify information provided in the News Release of August 29, 2007 detailing the historic resources of the Dorchester Deposit and the Goshen Copper Prospect.

Dorchester Deposit

The statement describing the Dorchester Deposit's historic resource of 6 million tonnes low-grade copper, previously reported in the August 29th News Release, is corrected below.

An historic estimate of 2.3 million tonnes 2.0% Cu was reported by Kirkham R.V. utilizing a private report prepared in 1974 by Canerpa-Amax. They classified the resource estimate as a 'possible reserve' using 'questionable data' which does not follow the guidelines in sections 1.2 and 1.3 of National Instrument 43-101.

The historic resource category of possible reserve is not a valid resource
classification under the current CIM categories. As no current feasibility
study has been done on the Dorchester Deposit's historic resource there is no assurance that the deposit will be found to be economically viable. As such the historic resource should not be considered as a reserve under the current CIM categories.

An additional historic estimate was filed in a work assessment report with the New Brunswick Department of Natural Resources by Gulf Minerals (Boyd,1977. They estimated 9,577,367 tons of 0.73% Cu which was not classified according to National Instrument 43-101.

Goshen Copper Prospect

An historic estimate of 25,000 tons 2.25% Cu was provided by Hawkins(1958) in his M.Sc. thesis utilizing a series of drill holes reported in the thesis. No classification of this historic estimate was provided by the author.

A qualified person has not done sufficient work with either the Dorchester Deposit or the Goshen Prospect to classify the historical estimate as current mineral resources or mineral reserves and the issuer is not treating either historical estimate as current mineral resources or mineral reserves as defined in sections 1.2 and 1.3 of National Instrument 43-101.

The historical estimates provided here should not be relied upon. They are provided to illustrate the occurrence of copper mineralization hosted within Maritimes Basin stratigraphy in southern New Brunswick.
