Sulphurets Zone Grows at Seabridge Gold's KSM Project

Seabridge Gold Inc. (TSX:SEA)(AMEX:SA) - 

Results of an off-set drill hole on the Sulphurets zone from this summer's
program at the Kerr-Sulphurets-Mitchell ("KSM") project confirms the extension
of a higher grade breccia zone in the Sulphurets resource area, prompting
Seabridge to drill two more off-set holes in this year's program. The Sulphurets
drilling appears likely to expand the Sulphurets resource model down-dip and
along strike to the northwest and northeast.


Seabridge Gold President and CEO Rudi Fronk said that the expansion of the
Sulphurets higher grade breccia zone "opens up the possibility of new
development options at KSM. If the results from S-08-06 are confirmed in the
next two holes, we believe that the Sulphurets and Mitchell Zones may merge and
could be exploited in a single pit."

Drill hole S-08-06 was collared in volcanic rock above the Sulphurets Thrust
Fault at azimuth 140 degrees and inclination -65 degrees. The aim was to
intersect the down-dip extension of the breccia zone 200 meters below S-06-04 at
right angles (see link). The intersections reported above are therefore believed
to be true widths. S-08-06 drilled through the Main Cu Target and encountered
the Sulphurets Thrust Fault at 301 meters down hole. Below the thrust fault, a
variable section of chlorite alteration in volcanic and intrusive rock and
silicic-hornfels in sedimentary rocks was encountered. Local brecciation of the
rock and abundant quartz-filled fractures appear to represent a down-dip
projection of the upper zone intersected in drill hole S-06-04. Additional
drilling this year will test for further down-dip and strike extensions of this
zone.


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 February 20, 2008 for details).

Based on results of this year's and previous drilling, Seabridge believes that
the Sulphurets zone is a continuously mineralized, moderately dipping, roughly
tabular gold-copper deposit measuring approximately 1,300 meters along strike
and up to 170 meters thick which remains open down-dip and along strike.


Exploration activities at Kerr-Sulphurets 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 resources by project and resource
category please visit the Corporation's website at

All resource estimates reported by the Corporation were calculated in accordance
with the Canadian National Instrument 43-101 and the Canadian Institute of
Mining and Metallurgy Classification system. These standards differ
significantly from the requirements of the U.S. Securities and Exchange
Commission. Mineral resources which are not mineral reserves do not have
demonstrated economic viability.

historical facts and are generally, but not always, identified by words such as
the following: expects, plans, anticipates, believes, intends, estimates,
projects, assumes, potential and similar expressions. Forward-looking statements
also include reference to events or conditions that will, would, may, could or
should occur. Information concerning exploration results and mineral reserve and
resource estimates may also be deemed to be forward-looking statements, as it
constitutes a prediction of what might be found to be present when and if a
project is actually developed. These forward-looking statements are necessarily
based upon a number of estimates and assumptions that, while considered
reasonable at the time they are made, are inherently subject to a variety of
risks and uncertainties which could cause actual events or results to differ
materially from those reflected in the forward-looking statements, including,
without limitation: uncertainties related to raising sufficient financing to
fund the planned work in a timely manner and on acceptable terms; changes in
planned work resulting from logistical, technical or other factors; the
possibility that results of work will not fulfill projections/expectations and
realize the perceived potential of the Corporation's projects; uncertainties
involved in the interpretation of drilling results and other tests and the
estimation of gold reserves and resources; risk of accidents, equipment
breakdowns and labour disputes or other unanticipated difficulties or
interruptions; the possibility of environmental issues at the Corporation's
projects; the possibility of cost overruns or unanticipated expenses in work
programs; the need to obtain permits and comply with environmental laws and
regulations and other government requirements; fluctuations in the price of gold
and other risks and uncertainties, including those described in the
Corporation's Annual Information Form filed with SEDAR in Canada (available at
