Seabridge Gold Reports Major Expansion of Mitchell Resource

Wednesday March 11, 8:00 am ET

TORONTO, CANADA--(MARKET WIRE)--Mar 11, 2009 -- Seabridge Gold (Toronto:SEA.TO -
News)(AMEX:SA - News) announced today that Resource Modeling Inc. ("RMI") has
completed an updated independent National Instrument 43-101 mineral resource
estimate for the Mitchell zone at its 100% owned KSM project. Measured and
indicated gold resources at Mitchell have increased by 89% over the previous
estimate to more than 30 million ounces. Measured and indicated copper resources
increased by 105% to nearly 6.0 billion pounds. Updated resource estimates for
the Sulphurets and Kerr zones will be announced shortly and a new NI-43-101
Technical Report covering all three zones will be filed on SEDAR within 45 days.

The updated independent resource estimate incorporates results from 34 core
holes totaling approximately 15,416 meters drilled by Seabridge at the Mitchell
zone during 2008. The 2008 drill program successfully upgraded almost all of the
667 million tonne inferred mineral resource in the 2008 estimate to the measured
or indicated category and also found extensions of the deposit to the south,
north and at depth.


The following table summarizes RMI's new updated global mineral resource
estimate as of March 9, 2009 with a comparison to their 2008 estimate:

Seabridge Gold President and CEO Rudi Fronk noted that "the Mitchell zone has
now become one of the world's largest undeveloped gold/copper deposits. We
successfully moved over 13 million ounces of inferred gold resources to the
measured or indicated category in 2008 and we found an additional 8 million
ounces of inferred gold resources, some of which may be upgraded in the 2009
program. Although the new inferred resources are somewhat lower grade than the
core of the Mitchell deposit, some of these resources represent a conversion of
material previously classified as waste in the upper benches of the mine plan
which should have a positive impact on the project."

RMI estimated gold and copper grades using inverse distance weighting methods
within gold and copper grade envelopes that were constructed for the Mitchell
zone. RMI notes that kriging results compare very favorably with the inverse
distance estimate. The grade models were validated visually and by comparisons
with nearest neighbor models. The estimated block grades were classified into
measured, indicated and inferred mineral resource categories based on
mineralized continuity that was determined both visually and statistically (i.e.
variogram ranges) together with the proximity to drill hole data. Recoverable
gold equivalent grades were calculated using a $650 gold price with a 70%
recovery rate and a $2.00 copper price with an 85% recovery rate.

The database for the Mitchell zone now incorporates 102 core holes totaling
40,060 meters of drilling. Seabridge Gold collected 90% of the Mitchell drill
hole data from its 2006, 2007 and 2008 drilling campaigns. RMI has reviewed the
quality assurance/quality control (QA/QC) protocols and results from Seabridge's
2006, 2007 and 2008 Mitchell drilling programs and has deemed that the number
and type of gold and copper standard reference materials (standards, blanks, and
duplicates) were reasonable. Based on the performance of those standard
reference materials, RMI believes that the Seabridge drill samples are
reproducible and suitable for estimating mineral resources.

Mineral resources for the Mitchell zone are summarized in the tables below at a
variety of recoverable gold equivalent cutoff grades.

RMI is an independent consulting firm under the direction of Michael J. Lechner,
Licensed Registered Geologist (Arizona) #37753, P.Geo. (British Columbia)
#155344, AIPG CPG #10690 and a Qualified Person under NI-43-101. Mr. Lechner
reviewed this news release.

Seabridge holds a 100% interest in several North American gold resource
projects. The Company's principal assets are the KSM property located near
Stewart, British Columbia, Canada (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 Seabridge's mineral resources by
project and resource category please visit the Company's website at
http://www.seabridgegold.net/resource.php.

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.

Statements relating to the estimated or expected future production and operating
results and costs and financial condition of Seabridge, planned work at the
Corporation's projects and the expected results of such work are forward-looking
statements within the meaning of the United States Private Securities Litigation
Reform Act of 1995. Forward-looking statements are statements that are not
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
www.sedar.com) for the year ended December 31, 2007 and in the Corporation's
Annual Report Form 20-F filed with the U.S. Securities and Exchange Commission
on EDGAR (available at www.sec.gov/edgar.shtml).
