Seabridge Gold's KSM Project Continues to Expand

TORONTO, CANADA, Oct 23 (MARKET WIRE) --
Seabridge Gold Inc. (TSX: SEA)(AMEX: SA)

Results from another nine holes drilled this summer at the
Kerr-Sulphurets-Mitchell ("KSM") project continue to confirm the
geological model and extend the resource area to the north and at depth.
Five of these were successful infill drill holes which are expected to
upgrade a significant portion of the project's inferred resources to the
indicated category. Hole M-08-73, a deep drill test following the
northwest plunge of the Mitchell zone, confirms the continuity of this
zone beyond the current model. Three geotechnical holes drilled to test
the proposed north and south pit walls identified several zones of
mineralization within the conceptual pit which had been classified in the
geological model as waste. To view the drill plan map, please visit the

To date, Seabridge has reported on 19 holes drilled this summer at KSM of
which five are exploratory, 11 are infill and three are geotechnical
(intended to evaluate slope stability for mining operations). Results
from another 11 holes are awaited. A total of 17,000 meters were drilled
in the now completed program.

Seabridge Gold President and CEO Rudi Fronk said the new results have
"exceeded our expectations. We will now need to expand our geological
model to incorporate extensions of the high grade plunge of the Mitchell
zone and to redefine material in the pit slopes that is currently
classified as waste. In addition, the success of our infill program
should mean a significant conversion of inferred resources into the
measured and indicated category."

The relationship of these new drill holes to the existing 3D model is
available as a link on the Seabridge Gold website (www.seabridgegold.net).

The Mitchell zone is now defined vertically as a continuously mineralized
body between 300 and 800 meters thick. The minimum dimensions of the
Mitchell zone have been established to be 1000 meters in a
northeast-southwest direction and 1600 meters in a northwest-southeast
direction. Mitchell remains open to the northwest along the recently
confirmed plunge of the higher grade core zone. All exploration and
infill holes were drilled to intersect the Mitchell zone perpendicular to
strike and are therefore believed to be true widths. True widths for the
intersections reported in the geotechnical holes are not known at this
time.

Descriptions of the nine new holes are as follows:

M-08-70: Infill drill hole in the central part of Mitchell at azimuth 190
degrees and inclination of -75 degrees. The hole intersected typical
Mitchell grades as predicted, but over a wider interval than expected.
Molybdenite abundance increases downhole,

M-08-71: Infill drill hole collared at 190 degrees with an inclination of
-55 degrees. This hole is on the eastern margin of the Mitchell zone and
contains Mitchell-style alteration and grades in the upper part of the
drill hole. Below 150 meters the drill hole passes into marginal
alteration styles and intensity marking the eastern margin of the
Mitchell zone.

M-08-72: Infill hole on the eastern margin of the deposit drilled at
azimuth 190 degrees and inclination of -55 degrees. The drill hole
encountered the predicted grade and alteration style from the geological
model in the upper 140 meters. The lower half of the drill hole
encountered less intense Mitchell-style alteration, further establishing
the eastern limit of the zone.

M-08-73: Deep north test in the western part of the zone, drilled at
azimuth 010 degrees and inclination of -85 degrees. Copper grades and
alteration are similar to those predicted in the geological model up
plunge from the pierce point of this hole. Slightly higher gold than
expected is observed in the middle of the intersection from about 100 to
450 meters. The drill hole confirms the continuity at depth beyond the
existing model and verifies the northwest plunge on the Mitchell zone.

M-08-75: Geotechnical drill hole on the north wall of the conceptual pit
design, drilled at azimuth 180 degrees and inclination -55 degrees. The
objective of this drill hole was to provide a vertical profile along the
north pit wall above the main Mitchell zone. Slope stability measurements
were collected from the drill hole as well as geochemical samples for
previously unrecognized mineral zones in the stripping profile of the
conceptual pit wall and above the upper limit of the Mitchell zone.
Multiple intervals of copper dominated mineral zones were encountered.
These zones are associated with the margins of intrusions and hosted in
sedimentary rocks or intrusive rocks. Styles of alteration and
mineralization are characteristic of occurrences above the Mitchell
Thrust Fault and can be best described as deep porphyry-style or
skarn-style targets. While these types of targets will likely not change
the exploration and development plans for the Mitchell zone, they may
convert waste material to ore in the north pit wall, potentially lowering
strip ratios and improving project economics.

M-08-76: Infill drill hole near the center of the Mitchell zone, collared
at azimuth 190 degrees inclination of -60 degrees. The drill hole
encountered the geology and alteration predicted by the geological model
but grades were slightly higher than the statistical model predicted.
Results from this hole are expected to upgrade inferred resources.

M-08-77: Infill drill hole at azimuth 190 degrees and -65 degrees
inclination in the south-central part of the Mitchell zone. A short
interval was drilled above the Mitchell Thrust Fault in moderately
mineralized rock. Well-veined and altered Mitchell zone rocks were
intersected immediately below the fault to the end of the hole, with vein
density and mineralization gradually diminishing with depth. Results were
similar to the model with slightly higher copper grades.

M-08-79: A north wall geotechnical hole drilled vertically in the upper
part of the conceptual north pit wall. The drill hole encountered
thermally metamorphosed andesite and intrusive rock. Mineral zones in
this part of the system are copper dominated skarn-style occurrences
associated with abundant magnetite. The drill hole was extended well
beyond its intended target to follow the magnetite skarn occurrence and
was terminated in the mineral zone.

M-08-80: Geotechnical drill test on the south conceptual pit wall
collared at 010 degrees azimuth and inclination of -67 degrees. The
objective of this drill hole was to provide a vertical profile along the
south pit wall above the main Mitchell zone. Slope stability measurements
were collected from the drill hole as well as geochemical samples for
previously unrecognized mineral zones in the stripping profile of the
conceptual pit wall and above the upper limit of the Mitchell zone.
Several narrow (less than 6 meters) gold-rich intervals were encountered
in the drill hole. The upper part of the hole contains a continuous
intersection of copper dominated mineralization that corresponds with and
overlaps a contact zone between intrusive and volcanic rocks. The 100%
owned KSM project, located near Stewart, British Columbia, Canada, is one
of the world's largest undeveloped gold/copper projects. The following
table summarizes NI 43-101 compliant mineral resources for all three
zones at the KSM project using a 0.50 gram per tonne (g/t) gold
equivalent cut-off grade (see news releases dated January 10, 2008 and

Exploration activities at KSM are being conducted by Seabridge
personnel under the supervision of William E. Threlkeld, Senior Vice
President of Seabridge and a Qualified Person as defined by National
Instrument 43-101. An ongoing and rigorous quality control/quality
assurance protocol is being employed during the 2008 program including
blank and reference standards in every batch of assays. Cross-check
analyses are being conducted at a second external laboratory on 10% of
the samples. Samples are being assayed at Eco Tech Laboratory Ltd.,
Kamloops, B.C., using fire assay atomic adsorption methods for gold and
total digestion ICP methods for other elements.

Seabridge holds a 100% interest in several North American gold resource
projects. The Corporation's principal assets are the KSM property in
British Columbia, one of the world's largest undeveloped gold/copper
projects, and the Courageous Lake gold project located in Canada's
Northwest Territories. For a breakdown of the Corporation's mineral
