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. The Sudbury gold stream covers the five producing mines, Coleman, Copper Cliff, Creighton, Garson, and Totten mines and one development stage project, the Victor Mine Project (“Sudbury Mines”).

The Sudbury Impact Basin represents the site of a 1.85-billion year old meteor impact that created a 200-250 km sized crater in the Earth's crust, and led to the development of the Sudbury Igneous Complex (SIC), a layered, impact melt sheet roughly 60 km by 30 km by 2.5 km thick. Magmatic Ni-Cu-PGE sulfide minerals, crystallised from mafic melts, sank due to density contrasts and formed as embayments in the footwall rocks of the SIC. The SIC represents the largest source of magmatic nickel in the world.

Vale also has a central concentrator and a smelter and refinery complex located in Sudbury, making this one of the largest integrated mining operations in the world. Vale has completed two key infrastructure initiatives in Sudbury, the Clean Atmospheric Emissions Reduction (“Clean AER”) project and Copper Cliff’s single furnace strategy.

*Comprised of the operating Coleman, Copper Cliff, Garson, Creighton, Totten and Stobie gold interests as well as the non-operating Victor gold interest. As of June 30, 2025, the Company has received approximately $344 million of operating cash flows from the Sudbury stream. Should the market value of gold delivered to Wheaton through the 20-year term of the contract, net of the per ounce cash payment, be lower than the initial $670 million refundable deposit, the Company will be entitled to a refund of the difference at the conclusion of the term. The term of the Sudbury PMPA ends on May 11, 2033.
