Drilling at Seabridge Gold's Kerr Deposit Yields Significant Metal Grades

Hole K-11-15 Intersects 34.3 Meters Grading 1.04 Grams Per Tonne Gold and 1.88% Copper

Seabridge Gold Inc. (TSX:SEA)(NYSE Amex:SA) -

Nine exploration holes drilled in 2011 at the Kerr deposit have returned some of the highest grades encountered to date at Seabridge Gold's 100%-owned KSM project in northwestern British Columbia. All nine of the core holes completed at Kerr (totaling 2,630 meters) intersected mineralization which is expected to add to resources and reserves and improve the project's economics.

Seabridge President and CEO Rudi Fronk commented that "this drilling has opened up the Kerr deposit down dip with better than expected grades. The results strongly suggest that we can add further higher-grade copper mineralization in future programs. Meanwhile, the holes drilled this year have likely upgraded inferred and unclassified material within the planned pit and should therefore contribute to reserve expansion in the new KSM Preliminary Feasibility Study planned for release in April 2012." (See attached cross-section).

An updated NI-43-101Mineral Resource Estimate for the entire KSM project and incorporating the Kerr drill results is scheduled for completion in the next 30 days.

Results from the nine Kerr holes drilled in the past year's program are as follows:

The above reported drill holes were designed to intersect the true width of the Kerr deposit, except where noted below. Several holes were drilled at oblique angles to the mineralized zone because of topographic constraints but results are considered to be meaningful as the drill holes were designed to pierce inferred resources and unclassified material contained within the planned Kerr pit. The reported assays have not been capped.

Descriptions of the above tabulated holes are as follows (see attached map for locations).

K-11-09: Located at the northwest end of the Kerr zone, drilled at an azimuth of 090° and inclined at -50°. Overburden to 5.1 meters, then an intensely bleached, foliated, quartz-sericite-pyrite altered rock and fault zone to 46 meters. The fault zone is interpreted to be a sub-horizontal break along which gravity induced slumping has occurred, placing a thin layer of unmineralized wall rocks over mineralized rocks. Fine disseminated chalcopyrite in similarly altered rocks below the fault to the hole bottom at 150 meters, except for intervals of late, barren mafic dykes from 117.9 to 127.2 and 146.5 to 146. The mineralization gradually decreases with depth as the hole transitions from the core of the Kerr zone to the footwall. This hole will convert unclassified and inferred material to indicated resources within the current pit model.

K-11-10: Targeted projected mineralization down-dip on the west side of the central Kerr zone, drilled at an azimuth of 089° and inclined at -57.7°. From 5 to 217.9 meters the hole cut intensely quartz-sericite-pyrite altered igneous rocks with late, barren mafic dykes from 80.2 to 94.8 meters, 124.1 to 136.7 meters and 173.4 to 191.2 meters. A projected upper part of the Kerr zone occurs from about 70 to 135 meters, however in this area it has been partially displaced by the late barren dykes. The lower or main Kerr zone runs from 217.9 to the hole bottom at 252 meters, and is characterized by chlorite alteration and anhydrite veining. The hole terminated in the zone but at this point is well below the conceptual pit bottom. This hole will convert unclassified and inferred material to indicated resources within the current pit model.

K-11-11: Collared at the southwest side of the Kerr zone, drilled at an azimuth of 090° and inclined at -65°, designed to test projected mineralization down dip in both Kerr zones. As expected for this area of Kerr, fine disseminated and fracture controlled chalcopyrite is correlative with the intensity of chloritic and silicic alteration of host andesitic tuff. Results from this hole will convert above average grade unclassified and inferred material to indicated resources blocks within the current pit model. Above the upper Kerr zone, scattered sub-centimeter scale, gold bearing quartz-carbonate veinlets are common, and assays up to 12.1g/t Au over 1.5 meters have been obtained.

K-11-12: Located at the northwest end of the Kerr zone approximately 150 meters north of K-11-09, drilled at an azimuth of 089° and inclined at -50°. Fine grained chalcopyrite in strongly foliated, quartz-sericite-pyrite altered volcaniclastic rocks throughout the drill hole.

K-11-13: Targeted projected ore down dip at the west side of the north-central Kerr zone drilled at an azimuth of 090° and inclined at -70°. Mineralization correlates with intensity of veining and chloritic alteration in tuff, however it appears overprinting quartz-sericite-clay-pyrite alteration may have had a leaching effect and removed some metal. Results will convert unclassified and inferred material to indicated resources.

K-11-14: Collared at the west side of the central Kerr zone, drilled at an azimuth of 142° and inclined at -75°, to test the down dip projection of mineralization within the current pit. Due to topographic constraints on drill pad positioning, an oblique azimuth was necessary to reach the target area. The location is in high, steep terrain typically under heavy snow cover, and was not accessible for drilling in previous years. Disseminated, vein and fracture controlled chalcopyrite abundance correlates with intensity of chlorite and silicic alteration accompanied by quartz stockwork veining in volcaniclastic rocks. The upper and lower Kerr zones almost coalesce in this location. These results will convert unclassified and inferred material to above average grade indicated resources within the current pit model.

K-11-15: Collared from the same location as K-11-14, but drilled at an azimuth of 142° and inclined at -48°, designed to cover the same target as K-11-14 on the section 70 meters to the south using an oblique azimuth due to topographic constraints. The geology and mineralization are similar to K-11-14. The hole terminated in strong mineralization below the current pit model. These results will convert unclassified and inferred material to above average grade indicated resources within the current pit model.

K-11-16: Collared approximately 275 meters south of K-11-14 and 120 meters north of K-11-11, tested the same down dip projection of mineralization within the pit in the south central Kerr zone. The abundance of disseminated, vein and fracture filling chalcopyrite correlates with chloritic and silicic alteration and associated quartz stockwork vein density in foliated volcaniclastic rocks. The lower Kerr zone has a higher stockwork density typically with magnetite and/or anhydrite, characteristic of higher grade areas of the Kerr deposit. The hole terminated in mineralization below the current pit model. These results will convert unclassified and inferred material to above average grade indicated resources within the current pit model.

K-11-17: Collared from the same location as K-11-14, but drilled at an azimuth of 355° and inclined at -70°, designed to cover the same target as K-11-14 approximately 100 meters to the north using an oblique azimuth due to topographic constraints. The geology and mineralization are similar to K-11-14 but less intense. The hole was terminated before reaching the lower Kerr zone as it was well below the pit model. These results will convert unclassified and inferred material to indicated resources within the current pit model.
