Drilling Confirms Likely Resource Enhancements at Seabridge Gold's Courageous Lake

TORONTO, CANADA--(Marketwire - Sept. 12, 2011) - Seabridge Gold Inc. (TSX:SEA)(NYSE Amex:SA) –

The second tranche of 2011 infill drill results from Seabridge Gold's 100% owned Courageous Lake Project are likely to expand the project's multi-million ounce gold resource, increase the average grade and upgrade inferred resources to higher categories. Assays from the latest 13 core holes (reported below) continue to confirm the project's resource model with some intercepts proving to be wider and better grade than predicted. In August, Seabridge reported results from the initial 10 core holes from this summer's infill drilling program which were also highly encouraging.

This year's $16 million program at Courageous Lake, located in Canada's Northwest Territories, is designed to generate the data required to complete a Preliminary Feasibility Study (PFS) in the second quarter of 2012. The drilling component of this program has four main objectives: (i) to upgrade inferred resources within the current FAT deposit pit plan by infill drilling, potentially qualifying them as reserves in the PFS; (ii) to complete geotechnical drilling required for pit slope and water management planning in the PFS; (iii) to condemn areas where project facilities will be located; and (iv) to look for new targets along the 53 kilometers of the Matthew's Lake greenstone belt held by Seabridge.

Assays have now been reported for 23 infill core holes totaling 7,460 meters drilled. Assays are awaited for another 25 infill holes totaling a further 6,060 meters drilled. An updated NI 43-101 compliant resource estimate is expected late this year incorporating the 2011 infill drilling results. Assays are also awaited for two promising new exploration targets drilled for the first time.

Seabridge President Rudi Fronk stated that the summer drill program is now complete and "we are more than satisfied that we have met our objectives. We are confident that we have upgraded a significant portion of the inferred resources which lie within the proposed pit and that these resources will therefore convert to reserves in our planned PFS. In addition, we are intrigued by the two new targets we drilled south of the FAT deposit. We own 53 kilometers – nearly the entire length – of a highly prospective greenstone belt which has gold occurrences all along it. As we move into the final stages of the FAT deposit PFS, we are beginning to expand our search for new deposits along the belt. We are excited to get back to exploration in such a promising geological environment."

Note: All assays have been capped at 10.1 grams of gold per tonne (g/T) True thicknesses of the above reported drill hole intercepts are estimated to be approximately 85-90% of the reported interval.

The FAT deposit is in the Slave Province, an extensive geological terrain in Canada's Northwest Territories. The deposit's name is an acronym for its dominant rock type, Felsic Ash Tuff. This gold occurrence, hosted by Archean greenstone rocks, was formed in a rhyolite/dacite dome complex that measures about 2km along strike and about 800m of stratigraphic section in width. Although tuffaceous rocks are the most common in the deposit there are also clear intervals of clastic and chemical sedimentary rocks and a few late intrusions.

In constructing a geological model for resource estimation, unique stratigraphic intervals were defined and labeled as domains 1 through 9 and domain 14. Each domain contains specific and unique tuff and sedimentary units arranged in particular stratigraphic sequences. The defined geological domains are relics of the depositional environment in which they were formed. Consequently, within these domains the style of rock types, hydrothermal alteration, vein occurrences and sulfide mineralogy are generally consistent across the length and breadth of each specific domain. Distribution of gold within a domain and the surrounding rock is treated differently from other domains in resource modeling. Although ten separate geological domains have been recognized in the FAT deposit, domains 3, 4 and 5 contain about 90% of the gold in the deposit.

Descriptions of the above reported holes are as follows:

CL-139: Drilled to the east in the south-central part of the deposit, this hole was designed to fill an un-tested portion of zone 5 and upgrade resources in zone 4. A variety of lithologies were encountered in this hole, including felsic ash tuff with varying crystal and lithic fragments and intercalations of thinly laminated siltstone. Sericite and silicic alteration were dominant and usually found together. Results from zone 5 were better than predicted by the model, but consistent with results from holes earlier this year. Zone 4 mineralization was broader and lower grade than expected, but should upgrade the class of resources in this area.

CL-140: Collared on the west side and drilled to the east, the hole was designed to test a gap in zone 5 and upgrade inferred resources in zone 4. This hole consisted of predominantly lithic felsic tuff with several narrow intervals of porphyritic tuff. Carbonate veining is common throughout this drill hole with mineralized intervals associated to sericite alteration. Mineralization in zone 5 compared well with holes drilled earlier this year and coupled with them should create new resources. Zone 4 mineralization was weaker than predicted by the model but will improve the classification of resources on this section.

CL-141: Drilled to the east in the north-central portion of the deposit and designed to upgrade inferred resources in zone 4 between previous drill holes. The hole intercepted felsic ash tuff and lapilli tuff sections typical of the FAT deposit. Mineralization is associated with strataform quartz veins and sericite alteration. The interval in zone 4 was higher-grade and slightly broader than predicted by the model, and will increase the volume of mineralized material in this area.

CL-142: Collared in the north-central part of the deposit and drilled to the east, this hole was designed to upgrade inferred resources in zones 5, 4 and 3. Felsic tuffs comprise the bulk of lithologies encountered. Alteration consisted of localized zones of quartz veining, silicic and sericite alteration. The predicted interval in zone 5 was not encountered, but the moderate grade and erratic distribution in zones 4 and 3 are as expected. This hole will push out the indicated resource limits to the near the edges of the defined deposit.

CL-143: Oriented to the east and located in the east-central portion of the deposit, this hole was designed to upgrade resources in zones 3 and 2. The dominant lithology encountered was felsic tuff with rare intercalations of siltstone. The top of the hole cut zone 4 and confirms the indicated blocks that were modeled in that location. The tightly constrained mineralization encountered in zone 3 is consistent with the model. A fourth unexpected interval in zone 3 seems to straddle the boundary between zones 3 and 2. The interval in zone 2 is as expected.

CL-144: Drilled to the east in the south central area of the deposit, this hole was designed to upgrade a gap in zone 4. Lithologies encountered alternate between felsic ash tuff and lithic tuff. Sericite alteration and quartz veining is most closely associated with mineralized zones. The mineralization in zone 5 was narrower than expected but significantly higher grade, while zone 4 was broader and slightly lower in grade than the model predicted. Overall both intercepts will upgrade the classification of resources.

CL-145: Located on the far western margin of the deposit and drilled to the northeast, the hole targeted inferred resources in zone 8. The top of the hole is characterized by felsic tuffs with intense carbonate alteration. The lower portion of the hole is dominated by sedimentary rocks. The mineralized section is stratigraphically above a graphitic unit that is heavily sheared. The mineralized zone was in line with expectations for width and location, but at more than twice the grade expected. This hole will upgrade inferred resources to the indicated category.

CL-146: Targeting zone 8 on the far west side of the deposit, this hole was designed to upgrade inferred resources. The top of the hole is in felsic tuff intensely altered carbonates, while the lower portion of the hole is dominated by sedimentary units. Dividing the two sections is a graphitic layer that is intensely sheared. Mineralization was less continuous in this hole than predicted by the model, but at higher grades. Inferred resources will be upgraded to the indicated category by this hole.

CL-147: Drilled to the east from the north-western side of the deposit, this hole was designed to upgrade inferred blocks in zone 4. A variety of lithologies were encountered including felsic ash tuff, intercalations of siltstone and volcaniclastic conglomerate. Mineralization exhibited a close spatial relationship with quartz veining and sericite alteration. The top 50 meters of the hole cut zone 9, with thicker and higher grades than predicted by the model. Mineralization in zone 4 was narrower and slightly lower grade than predicted by the model, but will upgrade the classification of inferred resources on this section.

CL-148: Collared in the south-central part of the deposit and drilled to the east, the hole was designed to upgrade inferred blocks in zone 4. The top portion of this hole begins in clastic sedimentary rocks and grading into felsic ash tuff. Quartz veins are common in conjunction with sericite alteration. Mineralization in general was very low-grade, broad and located in the predicted interval. The hole confirms the continuity of the zone, but does not enhance the grade of the resources.

CL-149: Drilled to the east and located in the east central part of the deposit, this hole was designed to test and upgrade resources in the zones 2 and 1. The lithologies of hole are predominantly felsic ash tuff, with infrequent thinly laminated siltstone. Gold mineralization is predominantly associated with quartz veining. Scattered narrow low-grade intervals in zone 2 were consistent with model predictions. The interval is zone 1 was narrower and lower grade than expected, but will still upgrade resources.

CL-150: Collared on the east side of the deposit and drilled to the west, this hole targeted inferred blocks near the bottom of the proposed pit in zones 3 and 4. The dominant lithology is lithic tuff. Mineralization is generally associated with moderate to intense sericite alteration and quartz veining. The mineralized intervals in zone 3 were both wider and higher grade than predicted by the model, and will upgrade and increase resources on this section. Results in zone 4 were as predicted, and will upgrade inferred resources to higher categories.

CL-151: Drilled to the east this hole was located on the south east side of the deposit and targeted zones 2 and 1. This hole is composed of felsic ash tuff, with thin volcaniclastic intercalations. Mineralization is associated with quartz veins and sericite alteration. The mineralized intervals in both zone 2 and 1 are slightly narrower than predicted by the model but at higher grades.
