Seabridge Gold Moving Deep Kerr Towards High-Grade Resource

New intercepts include 315 meters of 0.65% copper and 0.45 g/T gold

TORONTO, CANADA--(Marketwired - Oct 8, 2013) - Seabridge Gold (TSX:SEA) (NYSE:SA) announced today it has received additional exceptional drill results from the high-grade Deep Kerr core zone, confirming the likelihood of being able to calculate a sizeable resource estimate for the new discovery after just one season of drilling. Of 29 holes drilled at Deep Kerr this summer, 26 have hit the high-grade zone. Assays have been received to date for 15 of these 26 holes; all 15 have intersected wide intervals grading at or above 0.5% copper and 13 have major intercepts averaging above 0.6% copper.

Five diamond core drill rigs were deployed on the Deep Kerr target during most of the field season, generating 24,000 meters of core. Initially, the program explored the dip projection of the 1,800 meter long Kerr deposit. Preliminary evaluation of the target indicates that the strike potential of the core zone is at least 1,600 meters long, between 200 and 300 meters wide and at least 700 meters vertically; however Deep Kerr remains open along strike and vertically. In August, drilling was focused on about 1,000 meters of the strike potential to generate data for an initial resource estimate.

The Deep Kerr core zone is defined by a distinctive set of minerals and textures that include:

• Anhydrite, potassium feldspar and magnetite as alteration minerals.
• Abundant chalcopyrite and locally bornite with an observable decrease in pyrite.
• Intense fine shattering of quartz veins filled with copper minerals.

These features can be traced over the 1,000 meters of strike and 700 meters of vertical projection where drilling was concentrated during the season. Within the defined core zone, copper concentrations typically exceed 0.5% while the inner bornite-rich zone typically grades more than 1.0% copper. Gold concentrations, which are generally lower in the Kerr deposit, are significantly higher within the Deep Kerr core zone. Additional drilling will be required to determine if grades improve up-dip or down-dip from the 700 meter high vertical dimension drilled to date.

Chairman and CEO, Rudi Fronk commented that "the consistency of the Deep Kerr zone is surprising and very gratifying. Although much work needs to be done, deposits like this lend themselves to efficient and cost-effective mining. The grade continues to exceed our expectations and the overall size appears to be much larger than we originally anticipated."

Assay results from the next three core holes drilled at Deep Kerr this year are:

Drilling at Deep Kerr is employing state-of-the-art directional drilling tools operated by TECH Directional Services that enable additional holes to be started part way down a previously drilled hole. The Devico directional core barrel provided by TECH ensures that the new hole deviates from the first in a predictable manner to provide multiple intersections of the target, off-set from the original intercept. This technology significantly reduces the amount of drilling required to achieve a new intercept of the target zone as the top 400 to 800 meters of the hole is not re-drilled. The above-reported drill holes with a letter designation after the hole number represent wedged drill holes completed from holes that have been previously reported (i.e. K-13-23 and K-13-28). Drill hole K-13-23C was wedged from K-13-23 at 500 meters. Hole K-13-28A was wedged at 550 meters from K-13-28.

The above-reported drill holes were designed to intersect mineralized zones as close as technically feasible to a perpendicular angle to their strike. Therefore, the true widths of this mineralization are believed to be 75% or greater of the reported intercepts.

During the 2013 program, one hole, K-13-27, was terminated before intersecting the core zone. This hole did not deviate as expected and would not have been suitable for subsequent directional drilling. It was re-started and completed as drill hole K-13-28. Drill hole K-13-33 could not get through a fault zone and was abandoned; it was redrilled as K-13-34 and assays are pending. The southern limit for this year's program was established by drill hole K-13-26. The characteristic mineralogy and textures of the Deep Kerr core zone were not encountered in this drill hole and copper grades were low. Time constraints did not permit further investigation of this part of the system. K-13-26 could terminate the mineral system to the south but additional work is required to reach this conclusion. The system does extend an unknown distance to the north.

The KSM Project contains one of the largest undeveloped gold and copper reserves in the world. Its composite intrusive complex hosts four distinct hydrothermal cells that each produced large gold-copper porphyry deposits. Several of these hydrothermal cells show a direct genetic link to epithermal vein deposits including the neighboring Brucejack/Valley of the Kings development owned by Pretium Resources. The KSM mining district was joined to the North American continent well after the mineralizing event creating enormous deformation of the rocks that host deposits. As a consequence of this deformation the porphyry systems have been significantly modified and partly concealed. Seabridge continues to unravel this complex history of the district in order to discover additional mineralizing systems.

Proven and probable reserves at KSM are as follows:

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 2013 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 using fire assay atomic adsorption methods for gold, total digestion ICP methods for other elements, and atomic adsorption methods for Cu, Ag, Mo, Pb, Zn and As on samples with >0.5% Cu, by ALS Minerals Canada Ltd. in North Vancouver, B.C.

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.
