CANADIAN SHIELD INTERSECTS 107 METRES GRADING 99.1 g/t SILVER EQUIVALENT AT LA ESTRELLA

Toronto, Canada, November 23, 2007 – Canadian Shield Resources Inc. (TSX V:CSP) (“Canadian Shield" or the “Company”) is pleased to announce results from the Phase I drill program recently completed at the La Estrella Gold- Silver-Copper Property located in the Department of Huancavelica, Central Peru.

HIGHLIGHTS

- Drill Hole RC-E10 intersected 107 metres of 77.7 grams per tonne (g/t) silver and 0.39 g/t gold, a Silver Equivalent (AgEq) grade of 99.1 g/t or Gold Equivalent (AuEq) grade of 1.81 g/t, from 30 to 137 metres depth. o High Grade IntervaI includes 21 metres grading 0.62 g/t gold, 216.6 g/t silver or 250.3 g/t Silver Equivalent (AgEq) from 38 to 59 metres depth. Within this high grade zone, grades range from 36 g/t to 913 g/t silver and 0.211 g/t to 1.27 g/t gold from individual one metre sample intervals

- In Drill Hole RC-E11, the last 19 metres of that hole ended in 0.93 g/t gold, 58.8 g/t silver or 2 g/t Gold Equivalent (AuEq) or 109.5 g/t Silver Equivalent (AgEq). Grades range from 0.347 g/t to 1.77 g/t gold and from 17.8 g/t to 244 g/t silver over this uniformly mineralized interval to the bottom of the hole. RC-E11 was stopped at 163 metres due to difficult ground conditions.

The property comprises 1,300 hectares and hosts multi-episodic, low to intermediate sulfidation, epithermal gold-silver +/- copper +/- lead +/- zinc (polymetallic) mineralization. La Estrella is one of three properties that Canadian Shield acquired through its 90% acquisition of Anderson Peru Mining and Exploration S.A.C.

The table below summarizes drill results and displays continuity and multiplicity of higher-grade mineralized zones contained within a broad zone of disseminated, low-grade mineralization. Significant mineralization was encountered in 10 of the 11 drill holes. All intercepts are reported in drill length and do not represent true thickness which is to be determined. Furthermore, the intervals shown have been derived from a first pass analysis of the results and do not represent a rigorous economic evaluation. Gold Equivalent and Silver Equivalent were calculated assuming a 55 to 1 ratio of Gold to Silver. Although present in economically significant amounts in some holes, copper and lead are not factored into the gold and silver equivalent values.
