Seabridge Gold Reports Final 2008 Drill Results From Mitchell Zone

Updated NI 43-101 Resource Estimate Expected in February 2009

TORONTO, CANADA--(Marketwire - Dec. 22, 2008) - Seabridge Gold Inc. (TSX:SEA)(NYSE ALTERNEXT US:SA)

Results have been received from the final 13 holes drilled this summer on the Mitchell zone at the KSM project including two exploration holes to intersect the northern plunge of a higher grade zone, three in-fill holes to upgrade inferred resources to the indicated category and eight geotechnical holes designed to test the slope stability of the north and south walls in the proposed Mitchell pit (see attached plan map for drill hole locations). All 13 drill holes successfully met their objectives. Results from two more holes drilled this year at the Sulphurets zone have yet to be released.

Seabridge Gold President and CEO Rudi Fronk said the new results "enhance confidence in our resource model. We believe the results of the 2008 program should upgrade a significant portion of Mitchell's in pit inferred resources to the indicated category. We now have two more successful tests of the higher grade northern extension which should enable us to incorporate this feature into the next iteration of our resource model. Meanwhile, the geotechnical program could allow us to convert a significant amount of waste material into a mineable resource in addition to helping us define appropriate slopes for the Mitchell pit."

Assay data and descriptions for the final two exploration and three infill holes at the Mitchell zone are as follows:

All of the above listed intersections are believed to be true widths.

M-08-90: An in-fill hole drilled at 230 degrees azimuth, -60 degrees dip. This hole was designed to be drilled perpendicular to the northwest plunging main resource. This hole encountered higher than expected copper values.

M-08-91: Deep north exploration hole in western portion of the Mitchell resource drilled at 10 degrees azimuth, -80 degrees dip.

M-08-92: An in-fill hole drilled at 50 degrees azimuth, -60 degrees dip on the western end of the Mitchell resource. This hole had a similar objective as hole M-08-90, to drill perpendicularly across the plunge of the main resource.

M-08-93: Deep north hole drilled at 0 degrees azimuth and -85 degrees dip in the east end of the Mitchell resource. Moderately altered volcanic rocks produced a 500 meter intersect of average Mitchell gold and copper grades. This further illustrates the northerly dip to the main resource area.

M-08-94: An in-fill hole drilled at 180 degrees azimuth, -47 degrees dip designed to twin S91-395 which was drilled by Newhawk Resources in 1991. This hole was designed to verify the results of the historical drill hole, and to extend the hole below the proposed pit bottom. M-08-94 intersected higher gold grades in the top 190.5 meters than predicted by the historic drill hole. These results will eliminate an interpreted lower grade area in the resource that was created by incorporating this historical drill hole into the model.

The Mitchell zone is now defined as a continuously mineralized zone between 300 and 800 meters thick, 1000 meters in a northeast-southwest direction and 1600 meters in a northwest-southeast direction. The zone remains open to the northwest along the recently confirmed plunge of the core higher grade zone. The relationship of these new drill holes to the existing block model is available as a link on the Seabridge Gold website (www.seabridgegold.net 3D views of KSM).

True widths for the intersections reported in the geotechnical holes are not known at this time.

M-08-81: A vertical geotechnical hole drilled on the western end of the proposed north pit wall. The drill hole encountered metamorphosed andesite and altered intrusive rocks typical of the styles above the Mitchell thrust.

M-08-82: A vertical geotechnical hole drilled in the central portion of the proposed pit wall on the north side of the Mitchell resource.

M-08-83: Also a north pit wall drill hole. This drill hole was vertical, collared in the upper plate above the Mitchell thrust, and penetrated the fault zone at 122 meters.

M-08-84: A geotechnical drill hole drilled in the proposed south pit wall. This hole was drilled at 190 degrees azimuth and -65 degrees dip and was designed to penetrate through the pit wall. This drillhole was abandoned at 63 meters and was re-drilled as hole M-08-87.

M-08-85: A geotechnical hole drilled vertical on the eastern end of the proposed north side pit wall. This hole encountered metamorphosed sedimentary and volcanic rock above the Mitchell thrust fault with copper grades slightly higher than are typically found in the upper plate.

M-08-87: The second hole drilled from the site of M-08-84. This hole was steepened to -70 degrees dip along the original 190 degrees azimuth and completed as planned. This geotechnical hole was drilled to test the western end of the proposed south pit wall.

M-08-88: A geotechnical hole drilled at 190 degrees azimuth and -70 degrees dip in the central portion of the proposed south pit wall.

M-08-89: A geotechnical hole drilled at 190 degrees azimuth and -65 degrees dip on the eastern end of the proposed south pit wall. This hole encountered altered volcanic and sedimentary rocks in the top 232 meters above the Mitchell thrust with higher than average copper grades from the surface down to 213 meters.

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.
