Canadian Shield Intersects a Total of 42 Metres Grading 104.9 g/t Silver and 1.06 g/t Gold at La Estrella

Canadian Shield Resources Inc. (TSX VENTURE:CSP) ("Canadian Shield" or the
"Company") is pleased to announce the first assay results from Phase II diamond
drilling at the La Estrella Gold-Silver-Copper Property located in
Hucancavelica, Central Peru.


HIGHLIGHTS 

- DDH-E12, the first hole in the program, intersected 23 metres averaging 1.17
grams per tonne gold (g/t Au) and 143 grams per tonne silver (g/t Ag). This hole
is the extension of Phase I drill hole RC-E11, which was stopped at a depth of
163 metres due to difficult ground conditions. RC-E11 ended in 19 metres of 0.93
g/t Au, and 58.8 g/t Ag, or a Silver Equivalent (AgEq) of 110 g/t Ag.


- Combining the data from both holes, RC-E11 and DDH-E12, the mineralized
interval extends for 42 metres (from 144m in RC-E11 to 186m in DDH-E12) and
averages 1.06 g/t Au and 104.9 g/t Ag, (163.2 g/t AgEq).


- Gold values within this combined interval range from 0.125 g/t Au to 13.61 g/t
Au, while silver values vary from 24.6 g/t Ag to 1,401 g/t Ag (1.4 kilograms per
tonne silver) from 1-metre core samples.


- Hole DDH-E12 was stopped at a total depth of 245 metres in weakly-altered
volcanic sediments. Split core samples from the remaining 59 metres of the hole
have been submitted to the lab and results are expected shortly.


The Phase II Drill Program consists of a minimum of 1,500 metres of diamond core
drilling in 7-10 holes. The Company is presently drilling DDH-E14, the 3rd hole
of the program. Hole DDH-E13 was drilled as a twin to hole RC-E10, completed in
Phase I drilling, which intersected 107m of 99.1 g/t AgEq (see press release of
November 23, 2007). Results from the twinned hole will be used to compare assay
dependability between reverse circulation drilling in Phase I and core drilling
in the present program.


"We are off to an excellent start. These results double the length of the
intercept and upgrade the gold and silver values," says Phil Anderson, Canadian
Shield's VP Exploration. "The high grades are especially encouraging because
they suggest that we're still exploring the precious metal rich portion of the
system and now confirm that gold values continue with depth."


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.
