Project Overview

Vale’s Sudbury mines, located in Ontario, Canada, have an operating history dating back to 1885. Sudbury is one of the largest nickel producing areas globally and Vale's operations in Sudbury are among the largest in the world. The Sudbury gold stream covers five producing mines, the Coleman, Copper Cliff, Creighton, Garson, and Totten mines, and one development stage project, the Victor Mine Project (“Sudbury mines”). All ore bodies contain a mix of nickel, copper, platinum group metals, cobalt, gold, and silver.

In Sudbury, Vale also has a central concentrator, and a smelter and refinery complex, making this one of the largest integrated mining operations in the world. Vale is currently pursuing two key infrastructure initiatives in Sudbury, the Clean Atmospheric Emissions Reduction (“Clean AER”) project and Copper Cliff’s single furnace strategy. While the Clean AER project will not directly impact Wheaton Precious Metals' stream, we applaud Vale’s efforts to significantly cut emissions from their operations in Sudbury. The Copper Cliff’s single furnace strategy could have a marginally positive impact on Wheaton Precious Metals' attributable production as Vale notes that the initiative will improve production yields of copper and nickel. Vale has announced that the Stobie mine will be placed on care and maintenance later in 2017.

Precious Metal Purchase Agreement

On February 28, 2013, Wheaton Precious Metals entered into an agreement to acquire from Vale an amount of gold equal to 70% of the payable gold production from the Sudbury mines for a period of 20 years.

Wheaton Precious Metals paid Vale total cash consideration of US$570 million, plus 10 million Wheaton Precious Metals warrants with a strike price of US$65 and a term of 10 years (subsequently the strike price was reduced to US$43.75 as part of consideration for the third tranche of the 75% Salobo gold stream announced August 2, 2016). Wheaton Precious Metals will make ongoing payments of the lesser of US$400 and the prevailing market price, for each ounce of gold delivered under the agreement.
