       GOLD RESOURCES INCREASE BY 34% AT SEABRIDGE'S RED MOUNTAIN PROJECT
      NEW 43-101 TECHNICAL REPORT CONFIRMS POTENTIAL FOR FURTHER EXPANSION

TORONTO, CANADA... A new 43-101 Technical Report has been prepared by SRK
Consulting ("SRK") of Toronto on Seabridge Gold's 100% owned Red Mountain
project located in British Columbia, Canada. At a 1.0 gram per tonne ("gpt")
cut-off, SRK estimates an additional inferred resource of 1,729,000 tonnes at a
grade of 2.97 gpt gold (165,000 ounces) in close proximity to gold resources
previously reported by the Company for the project. SRK concludes that there is
excellent potential to further expand the gold resources at Red Mountain with
additional exploration drilling. The SRK Technical Report can be viewed at
www.seabridgegold.net/images/Red_Mtn_Tech_Report.pdf. With this addition, total
resources at Red Mountain are now stated as follows:

Red Mountain is a structurally-controlled, advanced-stage gold deposit located
18 kilometers east of Stewart, British Columbia. The deposit was originally
drilled by Bond Gold in the late 1980s, and was subsequently explored by Lac
Minerals and Royal Oak Mines. To date, approximately US$39 million has been
spent by previous owners at Red Mountain. Diamond drilling on the property has
totaled 127,000 meters in 467 holes. In addition, 2,000 meters of underground
workings have been excavated, including a 1,000-metre production-sized decline.

Previous resource estimates for Red Mountain concentrated on the Marc, AV and JW
zones. A Technical Report on these zones dated March 4, 2002 (available on
SEDAR) estimated measured resources of 1.26 million tonnes grading 8.01 grams of
gold per tonne (324,000 ounces) plus an indicated resource of 0.34 million
tonnes grading 7.04 grams of gold per tonne (76,000 ounces) for a total measured
and indicated gold resource of 400,000 ounces. In the inferred category, these
zones contain an additional 0.35 million tonnes grading 7.45 grams of gold per
tonne (83,000 ounces). In 2003, Seabridge commissioned SRK to undertake a
preliminary economic assessment of the stated resources at Red Mountain to
identify the best project development approach, and assess the potential
economics of the project. The study's preliminary projections included an 8 year
mine life with average cash operating costs of US$213 per ounce. (For details on
the preliminary economic assessment please see Seabridge's press release dated
September 23, 2003.)

The new SRK Technical Report addressed the 132 and 141 zones, which are located
in close proximity to the Marc, AV and JW zones. Data used by SRK in estimating
the Mineral Resources for Zones 132 and 141 include a sub-set of seventy-eight
boreholes totaling approximately 28,711 meters. Thirty-four of these holes have
intersected gold mineralization in Zones 132 and 141. The remaining forty-four
holes are peripheral to the Zones and were used to assist the interpretation of
geological data. Solid body models were created by SRK to encompass the gold and
silver mineralization above a 1.0 gpt gold cut-off. The original Gemcom block
model was expanded to accommodate Zones 132 and 141 by extending its western
boundary an additional 300 meters to the west and deepening it by another 100
meters. A bulk density of 2.91 was used to convert volumes into tonnages for all
blocks in the model for Zones 132 and 141. After statistical and geostatistical
modeling, SRK interpolated gold and silver grades into an expanded block model
by ordinary kriging. For comparison, gold and silver grades were also

interpolated using an inverse distance weighted cubed methodology. The Mineral
Resources estimated by SRK for Zones 132 and 141 of the Red Mountain gold
project are classified in the Inferred Mineral Resource category according to
the "CIM Standards on Mineral Resources and Reserves: Definitions and
Guidelines" (August, 2000). This classification is based primarily on the
drilling spacing and the lack of underground exploration data, which lower the
confidence in the lateral continuity of borehole data. This is consistent with
the classification used for the Marc, AV and JW zones.

The newly stated gold resource estimates were prepared by SRK under the
direction of Ron Deptuck, P.Geo, and including Kelly Sexsmith, P. Geo and
Jean-Francois Couture, P. Geo, all of whom are independent of Seabridge and are
Qualified Persons as defined by National Instrument 43-101. The newly stated
mineral resources do not have demonstrated economic viability and accordingly
are not mineral reserves.

Seabridge has been designed to provide its shareholders maximum leverage to the
price of gold. The Company has acquired a 100% interest in eight North American
gold projects which collectively contain an estimated 9.10 million ounces of
resources in the measured and indicated categories (246.3 million tonnes grading
1.15 grams of gold per tonne) plus an additional estimated 7.55 million ounces
of resources in the inferred category (203.1 million tonnes grading 1.16 grams
of gold per tonne). (See http://www.seabridgegold.net/gold_resources.htm for a
breakdown of these gold resources by project). The Company continues to seek
expansion of its gold resource base by acquisition of new projects and
exploration programs largely funded by partners.

WITH THE CANADIAN NATIONAL INSTRUMENT 43-101 AND THE CANADIAN INSTITUTE OF
MINING AND METALLURGY CLASSIFICATION SYSTEM. THESE STANDARDS DIFFER
