The Company announced results from a National Instrument 43-101 compliant Preliminary Feasibility Study
("PFS") of its 100% owned KSM project located in northern British Columbia, Canada. The PFS was prepared
by Wardrop, a Tetra Tech Company. The Executive Summary from the PFS can be found at
www.seabridgegold.net/KSM-PFS.pdf. The complete PFS will be filed on SEDAR at www.sedar.com within
The PFS reports reserves of 30.2 million ounces of gold, 7.0 billion pounds of copper, 133 million ounces of
silver and 210 million pounds of molybdenum. The Study also estimates a base case life of mine cash operating
costs of $144 per ounce of gold produced (net of base metal credits).
The PFS envisages a large tonnage open-pit mining operation at 120,000 metric tonnes per day of ore fed to a
flotation mill which would produce a combined gold/copper/silver concentrate for transport by truck to the
nearby deep-water sea port at Stewart, B.C. A separate molybdenum concentrate and gold-silver dore would
be produced at the processing facility.
