Our Global Assets

Precious Metals Streaming

Precious metals streaming allows Silver Wheaton to purchase, in exchange for an upfront payment, the by-product silver or gold production of a mine that it does not own or operate. The operating costs that Silver Wheaton pays for future production are pre-determined in the agreements, typically between US$4 to US$6 per ounce of silver and US$400 per ounce of gold produced, with a small inflationary adjustment in most contracts. This amount offsets our partners’ typical cost to produce an ounce of silver or gold.

Fixed costs reduce our shareholders’ downside risk while at the same time providing the upside to increases in the precious metals price. As well, other than the initial upfront cash payment, Silver Wheaton typically does not contribute to future capital expenditures or exploration costs invested by the mine; yet  it benefits from the production and exploration growth that results from these expenditures. This business model often translates into significant value creation for Silver Wheaton shareholders.
