Canadian Shield Resources Ltd. (TSX VENTURE:EXP) ("Canadian Shield" or the
"Company") is pleased to provide an update on the Estrella Project located in
central Peru, and the Colpayoc Project, located in the Yanacocha District of
northern Peru. Canadian Shield has recently completed a review of all
exploration data generated on these projects, including all trenches, rock
samples and drill hole cross sections.


The Estrella property has been drilled by the Company and prior operators and
the Colpayoc property has received historic trenching and drilling by prior
operators (1996-2007). In each case the Company has developed Exploration Target
Models for each project and Canadian Shield will prepare NI 43-101 technical
reports for each property. The exploration targets contain tonnages and grades
which are conceptual in nature. There is insufficient exploration to define a
mineral resource as defined by NI 43-101 and it is uncertain if further
exploration will result in discovery of a mineral resource. The Company has
previously released all significant drilling intercepts in news releases (see
www.canadianshieldresources.com).


The Estrella property contains a volcanic-hosted epithermal gold-silver system,
containing associated base-metal mineralization, hosted within a north-south
trending graben. Gold assays from outcrops and drill holes in the exploration
target range from 0.2 - 54.0 g/t and average 0.44 g/t gold. Silver
mineralization within the exploration target has assays which range from 15.0 -
1,400 g/t and average 21.15 g/t silver. The Estrella exploration target contains
a minimum of 35 million metric tonnes of mineralization and may contain up to 55
million metric tonnes or more of mineralization. The mineralized area is at
least 1,200 meters long (north-south) and approximately 200 meters wide
(east-west). The main area of mineralization occurs in a west dipping zone (-45
degrees), which is cross cut by sub-vertical, mineralized zones. In the
west-dipping zone, the mineralization remains open up-dip, down-dip, and along
trend to the north and south. Mineralization hosted in the near-vertical zones
remains open at depth, and along strike in both directions. These estimates are
intentionally conservative, and provide a clear indication of the location,
grade variation, and trend of the mineralization.


The Colpayoc property contains a central gold-copper porphyry system at the
Daylight Zone, and 5 additional target areas in the surrounding area with
epithermal gold-silver and skarn-hosted targets. The Daylight Zone has received
the largest amount of work. Assay results from trench and drill holes in the
main exploration target area range from 0.2 - 2.9 g/t gold with an average grade
of 0.50 g/t. The Daylight Zone exploration target contains a minimum of 25
million metric tonnes of mineralization and may contain up to 50 million metric
tonnes or more. Gold mineralization is hosted within an intrusive rock which is
exposed in a semi-circular area measuring roughly 400 meters in diameter,
surrounded by sedimentary rocks. Mineralization forms a nearly continuous
circular zone within the intrusion. Oxidation extends to a depth of
approximately 45 meters. Copper mineralization is present but has not been
evaluated in detail. The mineralized areas remain open at depth, in all
directions.


Estrella Property: The property contains 2,300 hectares and is located 130 km
south of Huancayo in the Department of Juancavalica. The property is accessed
via 65 km of high quality paved roads, and 65 km of high quality gravel roads.
The Company has a 90% interest in the property, with 10% owned by Anderson Peru
Mining and Exploration S.A.C. The property contains an outcropping, multiple
phase epithermal, intermediate sulfidation gold-silver system hosted in felsic
and intermediate volcanic and sub-volcanic intrusive rocks of probable Tertiary
age. Mineralization occurs with pervasive sericite (illite), clay, and lesser
silica alteration. The volcanic rocks overly limestone of Permo-Triassic age and
are hosted within a distinctive north-trending, fault-bounded graben.
Mineralization occurs in at least three different styles which are present
within a 1,200 meter north-south by 200 meter east-west zone. The largest area
of mineralization occurs as a north-south trending, west dipping, irregular,
stratabound zone made up of one to three sub-zones, which cumulatively measure
50 - 150 meters in thickness. The stratabound zones contain variable grade gold
and silver mineralization which occurs with disseminated and vein hosted pyrite,
tetrahedrite, galena and sphalerite. The zone has been intersected along strike
for 600 meters, and remains open for additional expansion to the north and
south. The stratabound zone also remains open up-dip, to the projected sub-crop
(beneath Quaternary alluvium), and down-dip. The second type of mineralization
occurs as a flat-lying tabular zone that ranges from 10 - 25 meters in
thickness, and is located at or near surface. The flat lying zone covers an area
that is approximately 200 meters east-west and 130 meters north-south, and
occurs above the west-dipping stratabound zone. The third type of mineralization
occurs as north trending, sub-vertical fault zones, containing silver and gold
mineralization, which cut both the west-dipping stratabound zone and the
flat-lying near surface mineralization.

This third type of mineralization outcrops at surface and has been intersected
in drill holes, extending north of the stratabound zone for a distance of 600
meters (north-south). The sub-vertical zone consists of multiple 3-15 meter wide
individual zones that occur within broader 60 - 80 meter wide zone. The
sub-vertical mineralization is topographically higher than the west-dipping
stratabound zone, which may be present at depth, below existing drilling. The
sub-vertical zone locally contains some of the highest grade mineralization on
the property, including drill intersections up to 11 meters @ 311.2 g/t silver
and 0.59 g/t gold (RC-E10 from 43-54 m). The sub-vertical mineralization also
remains open for expansion along trend to the north and south and at depth. The
overall depth of oxidation on the Estrella property is very near surface (less
than 5.0 m). The Company plans to undertake additional drilling to expand the
area of mineralization and in areas of higher grade mineralization. Drilling
will be planned to facilitate preparation of a NI 43-101 technical report.


Colpayoc Property: The property contains 4,200 hectares and is located 15 km
west of the city of Cajamarca and 15 km south of the Yanacocha mine complex,
operated by Newmont Mining Corporation. The Company has an option to acquire a
100% interest, subject to a 2% NSR royalty in the property. The property is
accessed along a 29 km improved gravel road from Cajamarca. The property
contains oxidized, outcropping gold and copper mineralization hosted within a
felsic intrusive, typical of a porphyry gold-copper system. The intrusion is
nested within two similar intrusions, all of which have intruded and are hosted
within Cretaceous age, massive limestone, calc-arenite, and siltstone. The
intrusions are circular and form a 400 meter diameter area of discontinuous
outcrop, surrounded by the sedimentary host rocks. Alteration consists of
variable density quartz-magnetite-pyrite-chalcopyrite stockwork and
sericitization within the intrusions, and variable skarn development and
decalcification within the sedimentary rocks. Mineralization, host rocks, and
alteration are similar to the Cerro Corona deposit, located in the northern
Yanacocha district. The property contains northwest trending fault zones, and
northeast trending fault zones within the sedimentary rocks. In several places,
these structures host variably brecciated felsic volcanics (possible vent
breccias), with precious metal mineralization, including gold assays up to 10
g/t and silver assays up 912 g/t reported from surface rock samples. These areas
have received only preliminary sampling at this time, and more systematic work
is required to assess the distribution of this mineralization. In summary, the
property contains three types of mineralization, which occur in six separate
target areas. The main area of mineralization, which has been explored and
evaluated (as described above) is the Daylight Zone/porphyry gold-copper
mineralization. Epithermal silver-gold mineralization is present within felsic
volcanics and skarn mineralization may be present, associated with a series of
magnetic anomalies within the sedimentary rocks, at depth. Canadian Shield plans
additional drilling to prepare a mineral resource estimate. Recently the Company
received opposition to its planned drilling program, from a community, located
adjacent to the Colpayoc Property. Canadian Shield is expanding its Community
Relations program and is negotiating an additional agreement.
