Seabridge Gold Drilling Expands and Upgrades KSM Project

TORONTO, CANADA--(Marketwire - Sept. 8, 2010) - Results from the 14 core holes drilled this summer at the Sulphurets deposit, part of Seabridge Gold's (TSX:SEA)(NYSE Amex:SA) 100% owned KSM Project, are likely to expand resources and upgrade resource classifications (see attached maps). This new data should allow for an increase in reserves in the updated Preliminary Feasibility Study ("PFS") scheduled for early 2011.

Seabridge President Rudi Fronk commented that "this program was designed to upgrade 68 million tonnes of inferred resources within the proposed Sulphurets pit to the measured and indicated categories thereby making them eligible for reserves classification. The drill results suggest that we have probably achieved this objective. Furthermore, the drilling encountered new mineralization which could add to resources and lead to a larger pit design for the Sulphurets deposit." 

Drilling continues at the Iron Cap zone with the aim of establishing a resource for this new target (see our news release dated July 26, 2010).

Results of the 14 holes drilled at Sulphurets are as follows:

Geologic descriptions of the 2010 Sulphurets drill holes are as follows:

S-10-16: A 351 meter infill hole on the west end of the Sulphurets deposit, drilled at 135° azimuth and minus 75° inclination to confirm a strike extension of the Sulphurets deposit to the west below the current proposed pit limits and to convert inferred resource blocks to the measured and indicated category. The hole confirmed the presence of altered volcanic strata consistent with the lower part of the Sulphurets deposit. This hole is likely to upgrade inferred resources to higher categories and extend the pit limits.

S-10-17: A 390 meter infill hole on the west end of the Sulphurets deposit drilled at 145° azimuth and minus 70° inclination to intercept the projection of two zones of gold and copper mineralization in the Sulphurets deposit that are currently classified as inferred resources. Both zones were intercepted in intense silica alteration with the upper zone narrower than predicted and the lower zone at the expected width with higher grades than predicted. Inferred resources are likely to be upgraded.

S-10-18: Drilled in the west end of the Sulphurets deposit to a total depth of 271.6 meters at azimuth 145° and inclination of minus 70°. A portion of the designed Sulphurets pit that did not contain any resource blocks was targeted by this hole. The continuation of ore zones from the east was confirmed in silicicly altered volcanic rocks, extending the gold and copper zones farther west than previously modeled. This hole is likely to add to resources.

S-10-19: A 276 meter infill hole at azimuth 145° and inclination of minus 70° into the west end of the Sulphurets deposit to target blocks of inferred resources. Alternating sedimentary and volcanic rocks were encountered with intense silica alteration and abundant quartz veins with sulfide minerals. This hole yielded higher gold and copper grades than predicted and should upgrade these resources from inferred to higher categories.

S-10-20: A 270 meter hole drilled on the west end of the Sulphurets deposit at azimuth 145° and inclination of minus 70°. The planned Sulphurets pit is currently limited in this area because of a large zone of inferred resource blocks which this hole was designed to upgrade. Sedimentary rocks interleaved with intrusions and volcanic rocks make up the sulfide and silica rich portions of this hole. Although the mineral zones were extended into this area, the intrusions may have been emplaced after the gold and copper mineralization, reducing the width of the zones. This hole is likely to upgrade inferred resources to higher categories and extend the pit limits.

S-10-21: A 432 meter vertical hole into the central part of the Sulphurets deposit to fill in an interval of inferred blocks above the main Sulphurets deposit, test the Main Copper zone above the Sulphurets Thrust Fault and provide geotechnical measurements for pit slope engineering. The porphyritic monzonite and hornfelsed rocks characteristic of the Main Copper target contained gold and copper grades higher than expected. In the upper zone of the Sulphurets deposit the projected intervals were encountered but contained lower grades than predicted; the lower Sulphurets zone was narrower but higher grade than predicted. Inferred resources are likely to be upgraded.

S-10-22: In the central part of Sulphurets this 369 meter hole was drilled at azimuth 325° and minus 80° inclination to target inferred resource blocks within the main Sulphurets deposit. Although the 68 meter width on the zone was narrower than expected, gold grades were in line with expectations while copper grades were substantially higher than the model. Inferred resources are likely to be upgraded.

S-10-23: A test of the deeper parts of the western limits of the Sulphurets deposits. This 531 meter hole was drilled at azimuth 145° and inclination of minus 70° to provide resource information beyond the western limit of the Sulphurets deposit, but within the designed pit shell. Three expected mineral zones were encountered with gold and copper grades typical of the Sulphurets deposit. Both the resource and reserve estimates should be expanded by these results.

S-10-24: A 351 meter hole drilled beyond the previous western limits of the Sulphurets deposit at azimuth 145° and minus 70° inclination to test the gap between the Sulphurets deposit and the Canyon target, which are thought to be a continuous zone separated by lack of drilling. An extensive section of altered sedimentary rock was encountered in this drill hole with intense silicic alteration and abundant sulfide minerals. Results in this hole demonstrate the continuity between Sulphurets and Canyon zones and should increase resources and extend the planned Sulphurets pit.

S-10-25: Drilled 303 meters at azimuth 145° and inclination of minus 70° between the Sulphurets and Canyon zones to fill in the gap between these two targets. Sulfide-bearing and intensely altered volcanic and sedimentary rocks were again intersected in this drill hole. Results continue to confirm the continuity of the Sulphurets and Canyon zones.

S-10-26:  A 399 meter hole on the eastern margin of the Canyon zone at 145° azimuth and inclination of minus 70° to expand the western limits of the Canyon zone and support the interpretation of continuity with the Sulphurets deposit. Abundant sulfide minerals and alteration correlate with the projection of the Canyon zone. Results will expand the Canyon target and eliminate the unclassified gap with the Sulphurets deposit.

S-10-27: A 508 meter hole in the southwest part of the Sulphurets deposit drilled at azimuth 025° and inclination of minus 70° to provide geotechnical measurements for the north side of the Sulphurets pit design. The upper mineral zones in this hole contain lower gold and copper grades than anticipated but this is well outside of the pit limits. The lower mineral zone contains gold and copper grade as expected.

S-10-28: A 300 meter down dip off-set on the Canyon zone drilled at azimuth 145° and inclination of minus 70° to expand the projected dip of the Canyon zone and demonstrate that its scale and continuity is consistent with the Sulphurets deposit. Abundant quartz-sulfide veins are characteristic of this hole, with the most intense veining on the projection of the Canyon mineral zone. Results are consistent with Sulphurets grades and should expand this deposit.

S-10-29: This 345 meter hole to the southwest of the Canyon zone at azimuth 145° and inclination of minus 70° tested the dip projection of the Canyon zone. Volcanic rocks predominate this hole with massive sulfide veins encountered within the projected Canyon zone interval. Broader than anticipated gold-copper intervals where encountered in this hole at grades typical of the Sulphurets deposit. Results from this hole demonstrate that the deposit is open along the southwest strike and down dip.

The above reported drill holes, with the exception of S-10-21 and S-10-27, were designed to intersect the true width of the Sulphurets deposit.
