Seabridge Gold Drills Spectacular Intercept Within Deep Kerr Deposit at KSM

TORONTO, CANADA--(Marketwired - Nov. 5, 2013) - Seabridge Gold SEASA today announced extraordinary results from hole K13-34 drilled into the recently-discovered Deep Kerr deposit on its 100%-owned KSM Project in north western British Columbia, Canada. A 640 meter wide intercept, the widest yet drilled at Deep Kerr, returned an exceptional average copper grade of 0.85% and 0.42 g/T of gold and exhibited at its center the highest grade core zone mineralization encountered to date.

Drill holes in the northern part of the Deep Kerr system, which were completed at the end of the 2013 program, have shown increasing widths and more abundant copper minerals. Early indications are that K13-34 could have encountered the overlap of multiple mineralizing phases which had been postulated by the Seabridge geological team based upon data from previous holes. These extraordinary results point to the potential for a substantially thicker, higher-grade zone within the Deep Kerr deposit with continuity along strike to the north and at depth. Results from the final five Deep Kerr drill holes are expected shortly. (For a drill hole location map and cross section of K13-34, see www.seabridgegold.net/DKmap6.pdf.)

Seabridge announced on August 12, 2013 that a higher-grade copper-gold core zone named Deep Kerr had been discovered beneath the Kerr porphyry deposit (see news release). A core zone discovery at Deep Kerr was the primary objective of this year's exploration program. 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, up to 300 meters wide and at least 700 meters vertically. In August, drilling was focused on about 1,000 meters of the strike potential to generate data for an initial resource estimate. Deep Kerr remains open along strike to the north and vertically. Assay results from drill hole K-13-34 are as follows:

Drill hole K-13-34 was drilled perpendicular to the strike of the Deep Kerr zone and was intended to intersect the true width of the body. We believe this intersection likely approximates true width but additional work and results from pending drill holes are required to confirm this interpretation.

The KSM Project contains one of the largest undeveloped gold and copper reserves in the world. Its composite intrusive complex hosts four large gold-copper porphyry deposits (Kerr, Sulphurets, Mitchell and Iron Cap) with direct genetic links to nearby epithermal vein deposits. The KSM mining district has undergone immense deformation as the rocks that host the four known porphyry deposits were bonded onto the North American continent during Cretaceous time. Seabridge has unravelled some of the complex history of the district which has led to the discovery of the Deep Kerr zone. These results are being incorporated into ongoing exploration for deep magmatic sources (known as core zones) elsewhere in the KSM district with the expectation of making additional high-grade discoveries.

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 greater than 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.

This information and these statements, referred to herein as "forward-looking statements" are made as of the date of this document. Forward-looking statements relate to future events or future performance and reflect current estimates, predictions, expectations or beliefs regarding future events and include, but are not limited to, statements with respect to: (i) the potential size of the Deep Kerr core zone along strike, vertically and in width; (ii) the proximity of intercepts to true widths; (iii) the increased widths and abundance of copper minerals to the north within Deep Kerr and the potential for a substantially thicker, higher-grade zone having continuity to the north and at depth; (iv) the possibility that drilling encountered the overlap of multiple mineralizing phases; (v) the estimated amount and grade of mineral reserves and mineral resources; (v) estimates of capital costs of constructing mine facilities and bringing a mine into production, including financing payback periods; (vi) the amount of future production; and (vii) estimates of operating costs, net cash flow and economic returns from an operating mine. Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives or future events or performance (often, but not always, using words or phrases such as "expects", "anticipates", "plans", "projects", "estimates", "envisages", "assumes", "intends", "strategy", "goals", "objectives" or variations thereof or stating that certain actions, events or results "may", "could", "would", "might" or "will" be taken, occur or be achieved, or the negative of any of these terms and similar expressions) are not statements of historical fact and may be forward-looking statements.

All forward-looking statements are based on Seabridge's or its consultants' current beliefs as well as various assumptions made by them and information currently available to them.
