Canadian Shield Intersects a Total of 70.5 Metres Grading 71.8 g/t Silver and 0.842 g/t Gold at La Estrella

TORONTO, ONTARIO--(Marketwire - Feb. 27, 2008) - Canadian Shield Resources Inc. (TSX VENTURE:CSP) ("Canadian Shield" or the "Company") is pleased to announce the final assay results from Phase II drilling on hole DDH-E12 at the La Estrella Gold-Silver-Copper Property located in the Department of Huancavelica, Central Peru.

HIGHLIGHTS

- Total depth of DDH-E12 is 245 metres with significant mineralization occurring between 144 and 214.5 metres.

- This 70.5 metre section grades 0.842 grams per tonne gold (g/t Au) and 71.8 grams per tonne silver (g/t Ag), including a number of thinner, higher grade intersections noted in the table below.

- Hole DDH-E12 is the diamond core extension of Drill Hole RC-E11 which ended in 19 metres of 0.93 grams per tonne gold (g/t Au) and 58.8 grams per tonne silver (g/t Ag) from 144 to 163 metres depth (see November 23, 2007 and January 29, 2008 press releases).

"The property is living up to our expectations returning the grade and width of mineralization that we feel will make a mineable deposit. We have completed 9 holes in this Phase II program and all the holes are visibly mineralized, hosted by a complex system of mineralized structures, lithologic contacts, hydrothermal breccias, along with sheeted and stockwork veining. We are anxiously awaiting more geochemical analysis" said Phil Anderson, VP of Exploration for Canadian Shield.

QUALITY ASSURANCE AND QUALITY CONTROL MEASURES

Canadian Shield exercises a strict chain of sample custody in all programs. The Company's personnel removes core from the drill rig and delivers it to a senior project geologist who marks the core into 1 metre sample intervals. Canadian Shield's personnel supervise the immediate splitting, sawing and bagging of samples, and packaging of groups of samples for dispatch to the lab. The remainder of the split core remains on site.

The Company's staff transports batches of samples 130 kilometres to Huancayo, where they ship the samples directly to SGS Laboratory's facility in Lima. At the lab, the samples are prepared by crushing and pulverizing and a 30 gram charge is assayed for gold by conventional fire assay and/or atomic absorption methods. Multi-element ICP analysis is carried out using a multi-acid digestion process. All samples that contain silver and/or copper, lead, and zinc values that exceed the upper detection limits for ICP are reanalysed by conventional atomic absorption methods to determine the absolute values of these metals.

Silver Equivalent (AgEq) was calculated assuming a 55 to 1 ratio of Gold to Silver. Metallurgical recoveries and net smelter returns are assumed to be 100%.

Phil Anderson, a "Qualified Person" as defined by National Instrument 43-101, supervised the program and approved the technical aspects of this press release.
