Canadian Shield Moves To Drill New Copper Discovery-September 15, 2005

TORONTO, ONTARIO--(CCNMatthews - Sept. 15, 2005) - Canadian Shield Resources Inc. (TSX VENTURE:CSP) (the "Company" or "Canadian Shield") is moving a drill rig onto its Cerro Cori Copper-Gold Property in order to test the recent discovery of copper mineralization.

A recent grab sample from an outcrop of altered brecciated monzonite, containing copper oxides, returned 4.63% copper. Elsewhere on the property an exposure of semi-massive sulphide was located during prospecting.

Canadian Shield recently expanded its land position at Cerro Cori and acquired the licence for an additional 1,000 hectares. The property now covers 3,994 hectares and other mining companies hold most of the surrounding mineral rights. The four Cerro Cori licences are located 500 km southeast of Lima, off the paved road between Lima and Cusco, at elevations between 4,400 to 4,700 metres.

Previous exploration by North Mining Inc. on the Cerro Cori Copper-Gold Property was sufficiently encouraging that they established a series of sites in preparation of drilling. North Mining Inc. was acquired by the Rio Tinto Group and the licenses lapsed. Subsequent work by Gallant Minerals Peru S.A. ("Gallant") prior to the involvement of Canadian Shield included geological mapping and geochemical sampling. The sampling identified areas anomalous in copper and molybdenum.

The prominent feature in this otherwise flat landscape is a hill of hematite boxwork, which at its peak is over 150 metres high, covering an area 500 metres long by 300 m wide. Similar boxworks are a characteristic of major copper porphyry deposits such as those operating in southern Peru.

The drill rig will be moved to Cerro Cori following the completion of the planned 1,500-metre program at the Humajala Gold Property, also located in southern Peru. Of the almost 1,000 metres of drilling completed to date at the Humajala Gold Property, several holes intersected intervals of up to 50 metres of intensely silicified breccia containing 2% to 10% visible sulphides or penetrative iron oxides. Gold assays are pending.

An induced polarisation and resistivity geophysical survey using a multi-separation pole-dipole array with an estimated depth of penetration of 300 m is in progress by the Peruvian subsidiary of Val D'Or Geophysics, in order to identify additional drill targets at the Humajala Gold Property in those areas which are covered by landslides and glacial debris.

The Humajala Gold Property and the Cerro Cori Copper-Gold Property are both held 100% by Gallant. Canadian Shield announced that ownership of Gallant had been increased to 66% on September 2, 2005 and the Company retains the right to increase ownership to 90% under the terms outlined in the press release of September 1, 2004.

Canadian Shield Resources Inc. is focused on the acquisition, exploration and development of precious metal and base metal properties in Peru. The Company's shares are listed on the TSX Venture Exchange (Trading Symbol CSP:TSX V).
