TORONTO, Feb. 18, 2014 /CNW/ - Seabridge Gold announced today that an independent mineral resource estimate for the recently discovered Deep Kerr Zone at its 100%-owned KSM Project in northwestern British Columbia, Canada contains an inferred resource of 515 million tonnes grading 0.53% copper and 0.36 g/T gold (5.9 million ounces of gold and 6.1 billion pounds of copper). The estimate is dated as at February 14, 2014. A National Instrument 43-101 compliant report is being prepared and will be filed on SEDAR at www.sedar.com within 45 days.

Seabridge Chairman and CEO Rudi Fronk noted that the Deep Kerr deposit is shaping up as a major copper-gold discovery. "Deep Kerr has the size and grade of a world class deposit and it is very well situated for low cost, efficient underground block cave mining. The resource model assumes this method of exploitation and is based on a set of realistic economic assumptions derived from similar deposits now in production. We therefore have a high degree of confidence that, with further work, Deep Kerr can mature into an outstanding opportunity for a large, high margin operation attractive to major mining companies."

Mr. Fronk also noted that the estimated Deep Kerr copper resource grade is more than two and one-half times the average of the KSM Project. "We set out last year to change the economic profile of KSM and we have succeeded in doing so. Before Deep Kerr, KSM was a gold project with a robust copper credit that would appeal primarily to gold miners as prospective partners. Now, KSM has a much stronger copper profile which, we believe, opens up the potential for a joint venture with a large base metal producer."

Key observations include:

• Excellent continuity of grade vertically and laterally within the deposit.
• Deep Kerr is wide open to the north and down dip, supporting the potential for substantial increases in both the size and grade of the mineralized envelope.
• Drilling completed to date indicates vertical zonation of sulfide minerals in the deposit and suggests that higher grade bornite could become more abundant than chalcopyrite down plunge. (Both bornite and chalcopyrite are copper minerals).

Resource Estimating Procedures:
Gold and copper grades were estimated by Resource Modeling Inc. ("RMI") using inverse distance weighting methods within geologically constrained gold and copper grade domains constructed for the Deep Kerr zone. The grade models were validated visually and by comparisons with nearest neighbor models. The drill hole database that was used for the estimate of mineral resources for the Deep Kerr Deposit consisted primarily of data collected from 32 core drill holes totaling approximately 35,000 meters of core drilling completed in 2012 and 2013. RMI reviewed the quality assurance/quality control protocols and results from Seabridge's 2012 and 2013 drilling program and has deemed that the number and type of gold and copper standard reference materials (standards, blanks, and duplicates) were reasonable. Based on the performance of those standard reference materials, RMI believes that the Seabridge drill samples are reproducible and suitable for estimating mineral resources.  Historical drill hole results were used in conjunction with the 32 recent Seabridge core holes to estimate block grades for the upper portion of the Deep Kerr resource.

The geological model for Deep Kerr used as the basis for the resource estimate defines a broad zone that is about 600 meters wide of altered rock believed to be a relict intrusion. Intensive alteration within this unique lithological zone contains the same alteration mineralogy seen in the district along with abundant anhydrite and magnetite. Coincident with this alteration, broad overlapping quartz stock work veins are dominated by chalcopyrite and locally bornite. The characteristic that distinguishes this zone from other KSM deposits is that pyrite is markedly decreased relative to copper-bearing minerals. These characteristics form a mineralized envelope that is consistent with a deep porphyry core deposit and were used to constrain the estimate of mineral resources.

Deep Kerr was treated as a block cave (bulk underground) mining target. The lateral and steep vertical continuity of the zone provides a geometric configuration that is likely to be amenable to these mining methods. Seabridge has retained Golder Associates and AMEC, both leading industry experts in underground mining, to undertake bulk underground mining studies for Deep Kerr. Resource estimation results were tested against possible underground mining shapes provided by Golder Associates culminating in mineral resources that were constrained within three dimensional wireframe shapes that represent potential underground mining limits. Resources were tabulated for three hypothetical draw point levels using various Net Smelter Return ("NSR") cut-off grades, which is a common industry practice for this type of a deposit. Evaluation of the economic potential of Deep Kerr was based on metal prices of $3.30 per pound of copper, $1250.00 per ounce gold, $23.00 per ounce silver, $14.40 per pound molybdenum and estimated metal recoveries from metallurgical test work. The resource estimate was further constrained by cost parameters derived from comparable operating block-cave mines around the globe, totaling $16.00 per tonne and consisting of $6.00 per tonne for mining and $10.00 per tonne for processing and G&A.

At this time, the Deep Kerr deposit is being evaluated as a stand-alone occurrence. To insure that the Deep Kerr resource does not overlap with the Kerr deposit which lies above it, the previously reported Kerr open pit resource was isolated by a fifty (50) meter buffer separating it from the new Deep Kerr resource. Additional drilling and advanced engineering analysis will be required before it is possible to evaluate whether or not Kerr and Deep Kerr can be combined in a single underground operation.

The above table reports undiluted inferred mineral resources above various NSR cut-off grades that are contained within a conceptual block cave shape. To be conservative, the initial Deep Kerr inferred resource is being reported at an NSR cut-off grade of $20 per tonne, as highlighted in the table above. The conceptual block cave shapes that were used to define the Deep Kerr inferred resources are based on a nominal 500 meter cave height.  Further engineering work will optimize the cave height to enhance overall project economics and reduce dilution. Infill drilling within the currently recognized inferred resource will be required to allow for detailed block cave optimization and a more accurate assessment of dilution. Mineral resources which are not mineral reserves do not have demonstrated economic viability. Inferred mineral resources have a high degree of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred resource will ever be upgraded to a higher category.

To indicate the potential significance of Deep Kerr, we have prepared the following table of proven and probable reserves reported by major producing copper-gold projects around the world. This data has been assembled from the latest available public disclosures by these companies:

Project	Owner	Location	Tonnes (millions)	Copper Grade (%)	Gold Grade (g/T)
Batu Hiju	Newmont	Indonesia	439	0.40	0.28
Bingham Canyon	Rio Tinto	United States	704	0.49	0.20
Cadia East	Newcrest Mining	Australia	1,600	0.29	0.49
Grasberg	Freeport	Indonesia	488	0.93	0.88
Oyu Tolgoi	Rio Tinto	Mongolia	1,040	0.46	0.31

The KSM project continues to expand. Exploration drilling planned for this year is designed to grow and improve the Deep Kerr resource.
