Streaming

Streaming allows Wheaton to purchase generally by-product precious metals or cobalt production from a mine that it does not own or operate in exchange for an upfront payment plus an additional payment upon delivery of each ounce or pound. The operating costs that Wheaton pays for future production are pre-determined in the agreements with a small inflationary adjustment in most contracts. This amount offsets our partners’ typical cost to produce the silver, gold, palladium or cobalt. 

Predictable costs reduce our shareholders’ downside risk while at the same time providing the upside to increases in the precious metals or cobalt price. Other than the initial upfront cash payment, 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 Wheaton shareholders.

  1. Subject to an annual inflationary adjustment with the exception of Loma de La Plata and Sudbury.
  2. Should the prevailing market price for silver or gold be lower than this amount, the per ounce cash payment will be reduced to the prevailing market price, with the exception of Yauliyacu where the per ounce cash payment will not be reduced below $4.30 per ounce, subject to an annual inflationary factor.
  3. Wheaton Precious Metals is committed to purchase from Primero a per annum amount equal to the first 6 million ounces of payable silver produced at San Dimas and 50% of any excess.
  4. Gold recoveries will be set at 55% for the Constancia deposit and 70% for the Pampacancha deposit until 265,000 ounces of gold have been delivered to the Company.
  5. Subject to an increase to $9.90 per ounce of silver and $550 per ounce of gold after the initial 40 year term.
  6. Wheaton Precious Metals is committed to purchase from Glencore a per annum amount equal to the first 1.5 million ounces of payable silver produced at Yauliyacu and 50% of any excess.

Should the market price of silver exceed $20 per ounce, in addition to the $8.80 per ounce, the Company is committed to pay Glencore an additional amount for each ounce of silver delivered equal to 50% of the excess, to a maximum of $10 per ounce, such that when the market price of silver is $40 or above, the Company will pay Glencore $18.80 per ounce of silver delivered.
  8. In October 2015, in order to incentivize additional exploration and potentially extend the limited remaining mine life of Stratoni, Wheaton Precious Metals and Eldorado Gold agreed to modify the Stratoni silver purchase agreement. The primary modification is to increase the production price per ounce of silver delivered to Wheaton Precious Metals over the current fixed price by one of the following amounts: (i) $2.50 per ounce of silver delivered if 10,000 meters of drilling is completed outside of the existing ore body and within Wheaton Precious Metals’ defined area of interest (“Expansion Drilling”); (ii) $5.00 per ounce of silver delivered if 20,000 meters of Expansion Drilling is completed; and (iii) $7.00 per ounce of silver delivered if 30,000 meters of Expansion Drilling is completed. Drilling in all three cases must be completed by December 31, 2020, in order for the agreed upon increase in production price to be initiated.
  9. The Company is committed to acquire 100% of the first 30,000 ounces of gold produced per annum and 50% thereafter.
  10. In October 2017, in order to incentivize Capstone Mining Corp. (Capstone) to extend to Minto mine life, the Company agreed to amend the Minto precious metal purchase agreement. The primary modification is to increase the production payment per ounce of gold delivered to Wheaton Precious Metals over the current fixed price in periods where the market price of copper is lower than $2.50 per pound. In consideration for this contract amendment and certain other agreements made between the Company and Capstone, the Company received shares of Capstone with a value of $8 million.
  11. Wheaton Precious Metals only has the rights to silver contained in concentrate containing less than 15% copper at the Aljustrel mine.
  12. The production payment related to the Keno Hill silver interest is a function of the silver head grade and silver spot price in the month in which the silver is produced.
  13. As per Barrick’s disclosure, closure activities were initiated at Pierina in August 2013.
  14. Wheaton Precious Metals’ attributable silver production is subject to a maximum of 8% of the silver contained in the ore processed at Veladero during the period.
  15. Terms of the agreement not yet finalized.
  16. Once 90 million silver equivalent ounces attributable to Wheaton Precious Metals have been produced, the attributable production to be purchased will decrease to 66.67% of silver production and 16.67% of gold production for the life of mine.
  17. Once 51,000 ounces of gold and 5.6 million ounces of silver have been produced, the stream will decrease to 66.67% of silver and gold production for the life of mine.
  18. Stream is effective January 1, 2021. Once 31 million pounds of cobalt are delivered, the stream drops to 21.2% of cobalt for the life of mine. Production payment is set at 18% of the cobalt spot price until the value of the upfront cash consideration is reduced to zero, then the production payment is 22% of the cobalt spot price.
  19. Stream is effective July 1, 2018. Wheaton will be entitled to an amount of palladium equal to: 4.5% of Stillwater palladium production up to 375 Koz: 2.25% of Stillwater palladium production between 375 Koz to 550 Koz delivered: and 1% of Stillwater palladium production thereafter for the life of mine. Production payment is set at 18% of the gold and palladium spot price until the value of the upfront cash consideration is reduced to zero, then the production payment is 22% of the gold and palladium spot price.
