Silver Wheaton is one of the largest metals streaming company in the world. The company currently has fourteen silver purchase agreements and two precious metals agreements where, in exchange for an upfront payment, it has the right to purchase all or a portion of the silver production, at a low fixed cost, from high-quality mines located in politically stable regions. Based upon its current agreements, forecast 2011 attributable production is 25 to 26 million silver equivalent ounces, including 15,000 ounces of gold.

By 2015, annual attributable production is anticipated to increase significantly to approximately 43 million silver equivalent ounces, including 35,000 ounces of gold. Beyond the initial upfront payment, no ongoing capital expenditures are required to generate this growth and Silver Wheaton does not hedge its silver production.
