Canadian Shield Expands Target for Phase II Drilling at La Estrella Property

Canadian Shield Resources Inc. (TSX VENTURE:CSP) ("Canadian Shield" or the
"Company") is pleased to announce that Phase II drilling is underway on an
expanded target area at the La Estrella epithermal gold, silver and base metal
property in central Peru. Results from completed Phase I Drilling included: 107
metres of 99.1 gram per tonne Silver Equivalent (g/t AgEq) in hole RC-E10, which
included 21 metres of 250.3 g/t AgEq (see press release of November 23, 2007).


The Phase II Diamond Drill Program consists of 1,500 metres in 7-10 core holes
designed to follow-up results obtained in the October 2007 Phase I Drill
Program. The results of a soil sampling survey conducted after the completion of
Phase I drilling significantly expanded the area of potential Au and Ag
mineralization.


"La Estrella is one of our highest-priority projects and we are excited about
this new development," said Phil Anderson, VP Exploration of Canadian Shield.
"The mineralization is structurally-controlled and trends north-south. The soil
sampling survey was designed to test the extension of the mineralized zone under
cover north of hole RC-E10 and to better understand localized lithological
controls. The assay results are significant throughout our sampling grid."


The table below summarizes the results of the soil survey. The sampling covered
a triangular area, roughly 400 metres on a side where 112 soil samples were
collected at 20-meter intervals along east-west grid lines. The northernmost
sample line averaged 0.67 grams per tonne gold (g/t Au) across 340 metres with
values ranging from 0.199 g/t Au to 1.463 g/t Au in soil. Of the total 112
samples, 18 (16%) ran over 0.60 g/t Au with one especially high value of 13.47
g/t Au occurring along strike 200 metres northeast of drill holes RC-E10 &
RC-E11. Furthermore, 26 samples (23%) ran between 0.10 and 0.59 g/t Au, 30
samples (27%) ran between 0.03 and 0.09 g/t Au, while the remainder of the
samples returned values under 0.03 g/t Au.

Silver and copper values are also highly anomalous. Silver values range from 1
to 30.4 g/t Ag. Copper values range from 8.2 to 442.5 ppm. The erratic
distribution of silver and copper values is the result of localized leaching. As
the pyrite-rich host rock weathers, the surface environment becomes increasingly
acidic and oxidizing. Both silver and copper are easily leached or depleted
under these conditions. In contrast, gold has clearly been enriched in
near-surface soils and forms a broader, more homogenous anomaly.


"Our drill results from Phase I suggest that we are exploring a gold-bearing
silver system or the silver-rich part of a gold-silver polymetallic epithermal
system. The fact that these soils are so enriched in gold is a very good sign,"
says Anderson. "As our working model for the property has evolved, we find that
we can now use gold as a key exploration guide to track mineralization."
