Seabridge Gold is a Toronto-based North American resource exploration company. It owns Kerr Sulphurets Mitchell (KSM), a copper-gold-silver-molybdenum porphyry project in northern British Columbia. KSM's proven-probable reserves amount to 38.2 million ounces of gold, 191 million ounces of silver, 9.988 billion pounds of copper and 213 million pounds of molybdenum. Gold reserves at the Courageous Lake deposit total 6.5 million ounces. The property is part of a bigger deposit containing another gold project known as Snowfield (Pretium Resources); the entire deposit is the largest undeveloped gold deposit in North America. The KSM project will cost more than $4.7 billion to build but funding is not yet in place.
