Seabridge drilling confirms Iron Cap as major new gold-copper deposit
New fourth KSM zone could significantly improve project economics

Monday, 26th July 2010

Toronto, Canada - Results from the first eight holes drilled by Seabridge at the Iron Cap target have confirmed a new, large potentially bulk minable deposit at KSM which could substantially improve project economics. Results to date include wide intercepts of gold, copper and silver grades above the KSM average. Infill drilling will now proceed at Iron Cap with the aim of establishing new proven and probable reserves to be included in mine plans for the project.  

Seabridge President Rudi Fronk commented that "results from our eight holes and five holes drilled by previous operators  have identified a new deposit that is at least 900 meters in strike length, 400 meters wide and up to 350 meters thick,  located immediately adjacent to the Mitchell zone [see attached maps]. What is most encouraging is that Iron Cap appears to have zones of higher grade copper which could be blended with ore from Mitchell to maintain our targeted 0.20% average copper grade to the mill. This average head grade is important because it generates a higher grade concentrate without sacrificing recoveries, which in turn commands better smelter returns and reduces shipping costs. The current mine plan calls for the early development of the more distant Kerr and Sulphurets zones to maintain copper head grades to the mill. Sequencing Iron Cap before Kerr and Sulphurets could have multiple potential benefits including lower operating and capital costs, deferring significant expenditures and extending mine life." Results from Seabridge's initial eight holes from Iron Cap are as follows:

 Iron Cap Drill Hole Results

Geologic descriptions of the eight holes are as follows:

IC-10-006:  Eastern part of Iron Cap zone, drilled at azimuth 135º with an inclination of minus 70º. The drill pierced thermally and hydrothermally altered sedimentary rocks with narrow intrusive and breccia bodies. Silicic alteration with intense quartz veinlets indicative of shattering by fluid pressure characterizes the rocks in this drill hole. Sulfide minerals are abundant and concentrated in the quartz veinlets.

IC-10-007:  North central part of Iron Cap, orientated at azimuth 135º and a minus 80º inclination. This hole collared in shattered and veined silicically altered and thermally metamorphosed sedimentary rocks. It passed into a shattered and veined intrusion with intense silica alteration. Numerous intervals of silica altered breccia with abundant sulfide minerals were recognized within the intrusion.

IC-10-008:  Central part of Iron Cap, drilled at azimuth 135º and a minus 80º inclination. Extensive silica alteration of tuffaceous and sedimentary rocks was encountered in the upper part of the drill hole. Deeper sections of the hole contained quartz-sericite altered intrusion and silica altered breccia.

IC-10-009:  North central part of Iron Cap, drilled at azimuth 135º and a minus 80º inclination. The hole encountered diorite to monzonite intrusion through most of its length. To about 174 meters, alteration intensity increases beginning with moderate-intensity chlorite alteration grading to intense silica and potassic alteration. Below 174 meters, intensity of silica alteration remains consistent to the end of the hole, with veining and sulfide abundance decreasing at depth.

IC-10-010:  North central part of Iron Cap, drilled at azimuth 135º and a minus 80º inclination. The drill hole encountered breccia through most of its length. The breccia generally has intensely altered fragments in a matrix of silica and sulfide minerals, with occasional zones of intense veining superimposed on the brecciated rock.

IC-10-011:  Northeast part of Iron Cap, orientated at azimuth 135º with an inclination of minus 70º. The drill hole collared in brecciated rock, passed into a section of silicically altered pyritic sedimentary rocks and then into a fine grained intrusion. The breccia and intrusive rocks are dominantly sericite altered. The highest grade gold zone straddles the contact between the intrusion and sedimentary rocks.

IC-10-012:   Far northeast part of Iron Cap, drilled at azimuth 135º and a minus 70º inclination. The upper parts of this drill hole are alternating intervals of sedimentary and tuffaceous rocks with diorite intrusion. Alteration is principally silica with abundant stockwork veins. The lower third of the drill hole encountered silicic and pyritic sedimentary rocks and very fine grained felsic volcanic rocks.

IC-10-013: North central part of Iron Cap, orientated at azimuth 135º and minus 80º inclination. The entire drill hole displays low intensity alteration in a porphyritic intrusive rock. The upper third of the hole is dominated by silicic alteration with patchy potassic alteration. Below a distinct fault zone in the hole, the lower 2/3 is altered in alternating intervals to chlorite-rich and silica-rich alteration assemblages.

The above reported drill holes were designed to intersect the true width of the Iron Cap zone.

The 100% owned KSM project, located near Stewart, British Columbia, Canada, is one of the world's largest undeveloped gold/copper projects. Proven and probable reserves for the KSM project (see news release dated March 31, 2010 for details) using a gold price of US$850 per ounce and a copper price of US$2.25 per pound are as follows:

KSM Proven and Probable Reserves

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. Mr. Threlkeld has reviewed and approved this news release. An ongoing and rigorous quality control/quality assurance protocol is being employed during the 2010 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 Company's principal assets are the KSM property located near Stewart, British Columbia, Canada and the Courageous Lake gold project located in Canada's Northwest Territories.

All reserve and resource estimates reported by the Corporation were calculated in accordance with the Canadian National Instrument 43-101 and the Canadian Institute of Mining and Metallurgy Classification system. These standards differ significantly from the requirements of the U.S. Securities and Exchange Commission. Mineral resources which are not mineral reserves do not have demonstrated economic viability.
