Drilling Upgrades and Expands Gold Resources at Seabridge's Courageous Lake Project

New results could add measurably to a mineral reserve estimate expected in second quarter of 2012

TORONTO, CANADA--(Marketwire - Aug. 9, 2011) - Seabridge Gold Inc. (TSX:SEA)(NYSE Amex:SA)

Results from the first 10 infill core holes drilled this summer at Seabridge Gold's 100% owned Courageous Lake Project are likely to expand and upgrade the project's multi-million ounce gold resource. Another 38 infill holes will be drilled before the program ends this September.

This year's $16 million program at Courageous Lake is designed to generate the data required to complete a Preliminary Feasibility Study (PFS) 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.

Seabridge President Rudi Fronk commented that "the infill drilling this year is once again confirming the reliability of our resource model for the FAT deposit. Last year's similarly-sized program upgraded 2.5 million ounces of inferred gold resources to higher categories and also added new resources. Based on the first 10 holes drilled this year, we expect a similar result, which will have a significant positive impact on the project." An updated NI 43-101 compliant resource estimate is expected late this year incorporating the 2011 drilling results.

Note: All assays have been capped at 10.0 grams per tonne gold. True thickness of the above reported 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 initial ten holes drilled this year at Courageous Lake are as follows:

CL-129: Collared in the west-central part of the FAT deposit, this east directed drill hole was designed to upgrade inferred resource blocks in zones 5 and 4. The hole intercepted a diverse package of felsic volcanic rocks including lapilli-rich, crystal-rich and ash tuff units. Sericite was the most common alteration style but locally abundant carbonate and chlorite alteration with sulfide replacement of lapilli fragments was also identified. Results from zone 4 were about as expected, however zone 5 contained a much broader zone of mineralization. New gold resources are expected to emerge from zone 5 and within zone 4 resource blocks will be upgraded to the indicated category.

CL-130: The hole was drilled to the east and designed to fill an untested gap in zone 5 and upgrade inferred resource blocks in zone 4 between other existing drill holes. At 10.5 meters the hole encountered lapilli and ash tuff with variable sericite alteration. In zone 5 more tuffaceous material then usual was intersected, with the width of grade intervals about as expected but at much higher grades. Zone 4 contained narrower zones at average grades. Inferred blocks should be upgraded from zone 4 and new resources are expected from zone 5.

CL-131: Collared in the central part of the deposit targeting the shallow parts of zones 4, 3 and 2 with the intent of upgrading inferred resource blocks. This hole encountered lapilli tuff through zones 4 and 3 then passing into textureless ash tuff below 175 meters at the top of zone 3 and into zone 2. Sericite and silica-sericite alteration dominate throughout the mineralized zones. Zones 4 and 3 contained broader and higher grade zones than predicted in these shallow parts of the resource model. Grades in zone 2 were about as predicted but shifted west of the projected interval. This hole will fill the gap of inferred blocks in the shallow parts of zones 4 and 3 and should extend grades deeper in zone 2.

CL-132: Drilled from west to east in the south-central part of the FAT deposit, the hole was designed to upgrade inferred resource blocks in zones 5 and 4. This drill hole intersected several fault and fracture zones within a lapilli tuff package. Sericite alteration is dominant in the tuff units whereas silica alteration characterizes the broken fault zones. Results from zone 5 indicate that the grades within the mineralized zone split into two discreet bands that will modify our resource model in this area. Continuity of grades was established in zone 4 between surface and underground drill holes along this section. Results from this hole will upgrade inferred resource blocks in both zones and establish better control on metal distribution in the deposit.

CL-133: Designed to upgrade the shallow parts of zones 5 and 4, the hole was drilled from the west in the south central part of the deposit. Lapilli tuff with sericite alteration is the bulk of the rock encountered in the drill hole and is typical of these mineralized zones. In zone 5, three discreet intervals were intersected with the second zone containing much better grade than predicted and the third zone was unexpected. Zone 4 encountered an unexpected interval at about 156 meters, but the remaining part of the zone indicates grades are diminishing toward the surface. The hole was successful in both zones 5 and 4 in upgrading inferred resource blocks and confirming the absence of significant mineralization near the surface as predicted.

CL-134: Collared in the south central part of the deposit and drilled to the east, the hole was designed to extend and upgrade resources in the shallow parts of zones 5 and 4. The hole encountered lapilli tuff with intense sericite alteration and local zones of silica or chlorite alteration. In zone 5 grades were above those predicted by the model. Zone 4 contained multiple intervals rather than the predicted continuous zone, but grades were about those predicted or higher. Continuity of indicated blocks should be established in zone 4 and all categories of resource blocks should be increased in zone 5.

CL-135: The hole was designed to upgrade inferred blocks in zones 5, 4 and 3 within the designed pit limits and was drilled from west to east in the south central part of the deposit. The tuff lithologies encountered in each of the mineralized zones were as predicted, with intense sericite alteration throughout. In zone 5 multiple unexpected grade intervals were encountered and the predicted interval was broader and higher grade than anticipated. In the zones 4 and 3 results were about as expected. Inferred resources blocks should be converted to indicated classification along this section.

CL-136: Drilled in the southern part of the deposit and oriented to the east, it was designed to upgrade shallow inferred blocks in zone 5 and fill gaps in zones 4 and 3. Lithologies and textures were consistent with the modeled zones in this part of the deposit, though alteration was weaker than anticipated. Results from zone 5 were slightly lower grade than expected but will still upgrade and add blocks. Results from zone 4 were better than predicted, where only scattered low-grade mineralization was expected. In zone 3 only low-grade intercepts were encountered as predicted by the model. Overall this hole will upgrade inferred and add new indicated blocks to the model.

CL-137: Drilled from the west in the south-central part of the FAT deposit, this hole was designed to fill a gap in zone 5 and upgrade inferred blocks in zones 4 and 3. The hole encountered sericite altered felsic tuff units throughout its length. Textures of the tuff varied between lapilli-rich, lapilli-poor and block sized fragments, consistent with the styles of tuff identified in the mineralized zones. Results from zone 5 were not predicted in the current resource model. Zone 4 contained narrower or similar width intervals to that predicted but at much higher grade and zone 3 showed that grades had become slightly narrower and shifted eastward from the model prediction. This hole will upgrade inferred and add new resources to the model.

CL-138: Designed to upgrade inferred blocks in zone 5 and 4, this hole was drilled on an east orientation in the south central part of the deposit. Typical felsic tuffs with variable lapilli content and sericitic and silicic alteration were encountered in both mineral zones as expected. Mineralization in zone 5 exceeded expectations in both grade and width of the mineralized interval. The interval in zone 4 was narrower than expected but at more than twice the grade predicted. Overall this hole will upgrade inferred and add new resources to the model.
