Study Predicts 15 Year Mine Life with Average Annual Gold Production of 385,000 Ounces.
At Current Gold Prices,Estimated Pre-Tax NPV is US$1.1 Billion at a 5% Discount Rate.

Toronto, Canada...Seabridge Gold announced today the results of its first Preliminary Feasibility Study ("PFS") for its 100%-owned Courageous Lake project located in Canada's Northwest Territories. The study demonstrates that Courageous Lake is an economic project at the current gold price while also offering substantial leverage to higher gold prices. The PFS was prepared by Tetra Tech Wardrop ("Tetra Tech"). The PFS Executive Summary can be found at www.seabridgegold.net/CL_ExecSum_2012.pdf. The complete PFS will be filed at www.sedar.com within 45 days.

Commenting on the study, Seabridge Chairman and CEO Rudi Fronk said: "Our business plan from inception has been to grow gold resources and reserves while minimizing equity dilution. With an estimated 6.5 million ounces of newly defined proven and probable reserves at Courageous Lake, combined with the 38.2 million ounces of gold reserves estimated at our KSM project, we now report total proven and probable gold reserves of 44.7 million ounces. Not only does this rank Seabridge among the top ten companies in the world with respect to gold reserves, but with only 43.4 million common shares outstanding, we provide our shareholders with more than one ounce of gold reserves per common share outstanding. Furthermore, this entire reserve base is located in Canada, one of the safest and most mining-friendly jurisdictions in the world." Proven and probable reserves at KSM are estimated at 2.2 billion tonnes grading 0.55 grams per tonne gold, 0.21% copper and 2.74 grams per tonne silver.

Mr. Fronk noted that Seabridge will continue to optimize the Courageous Lake project. "We believe the most cost effective way to improve project economics is to add to reserves. We are now drilling some highly prospective targets which could be accessed easily by the operation proposed in the PFS."

The Courageous Lake PFS is based on a single open-pit mining operation with on-site processing. A base case scenario was developed for the project incorporating an estimated 91.1 million tonnes of proven and probable reserves at an estimated average grade of 2.20 grams of gold per tonne feeding a 17,500 tonnes per day operation (6.1 million tonnes per year annual average throughput). This yields a projected 15 year operation with average estimated annual production of 385,000 ounces of gold at a projected life of mine average cash operating cost of US$780 per ounce recovered (US$674 in years one to five). Start-up capital costs for the project are estimated at US$1.52 billion, including a contingency of US$187 million.

At a gold price of US$1,384 per ounce (the 3 year trailing average gold price at July 3, 2012), the base case has an estimated US$1.5 billion pre-tax net cash flow, a US$303 million net present value at a 5% discount rate and an internal rate of return of 7.3%. This base case is consistent with the requirements of securities regulators. At a gold price of US$1,618 (the spot price on July 3, 2012), the estimated total pre-tax net cash flow nearly doubles that of the base case to US$2.8 billion, the net present value at a 5% discount rate more than triples to US$1.1 billion and the internal rate of return increases to 12.5%. To demonstrate the leverage to gold price, an alternative case was run using last year's gold price high of $1,925 per ounce which yielded a pre-tax net cash flow of $4.5 billion, a net present value at a 5% discount rate of $2.1 billion and an internal rate of return of 18.7%.

The PFS also identifies several opportunities that could significantly improve the overall project economics. First, the current design incorporates a combination of diesel and wind generated power resulting in a projected power generation cost of Cdn$0.184 per kilowatt hour which is nearly 40% lower than power generation by diesel fuel alone. Seabridge is evaluating nearby potential hydro-electric sources which would also provide reliable, sustainable and lower-cost clean energy source and significantly reduce the requirement for diesel fuel at the site. Secondly, access to the project under the current design is by winter road which is limited to less than three months per year. It is during this period that almost all of the project's supplies are transported to site. The Tibbitt to Contwoyto Winter Road Joint Venture proposes extending the winter road seasonal use by at least another month with a 150 km extension from the permanent road access at Tibbitt Lake to Lockhart camp. While this would result in some reduction in both operating and capital costs for Courageous Lake, an all-season access road from the Bathhurst Inlet would provide considerably more benefit to Courageous Lake economics. Seabridge will continue to investigate these options as the project moves forward.

Mine Planning

Lerchs-Grossman ("LG") pit shell optimizations were used to define the mine plans in the PFS. The pit optimizations incorporated estimated costs for mining, processing, tailings management, general and administrative and gold recovery rates. Waste to ore cut-offs were determined using a gold price of US$1,244 per ounce. Estimated in-pit diluted proven and probable reserves, including mining dilution within the ultimate pit limit based on a Cdn$20.10 per tonne cut-off, are as follows:

Unit Operating Costs

Proven and probable reserves are derived from estimated total undiluted measured and indicated resources of 8.0 million ounces of gold (107 million tonnes at an average grade of 2.31 grams of gold per tonne).

Mineral Processing

Seabridge has conducted five major metallurgical testing programs since 2003. The comminution proposed for Courageous Lake uses an energy efficient process including: (i) primary crushing by gyratory crusher; (ii) secondary crushing by cone crusher; (iii) tertiary crushing by high pressure grinding rolls; and (iv) final grinding by ball mills. The recovery process includes conventional flotation, flotation concentrate pressure oxidation, cyanidation and gold refining circuits. Overall gold recovery is projected at 89.4%.

Capital Costs

Start-up capital costs (including contingencies of US$187 million) are estimated at US$1.52 billion and are summarized as follows:


Start-up Capital Costs

Operating Costs

Average mine, process and G&A operating costs over the project's life (including waste mining) are estimated at US$47.35 per tonne milled. A breakdown of estimated unit operating costs is as follows:

Economic Analysis

A base case economic evaluation was undertaken incorporating historical three-year trailing averages for gold prices and currency exchange rates as of July 3, 2012. This approach is consistent with the guidance of the United States Securities and Exchange Commission, adheres to National Instrument 43-101 and is consistent with industry practice. A spot price case was prepared using the July 3, 2012 spot gold price and currency exchange rates. To demonstrate the leverage to gold price, a third case was prepared using last year's gold price high of $1,925 per ounce. Pre-tax economic results for all three cases are as follows:
