Corporate Updates 

On March 30, 2017, the Company and Alexco Resources Corp. ("Alexco") agreed to amend the Alexco Silver Purchase Agreement to adjust the silver production payment from US$3.90 per ounce of silver delivered to Silver Wheaton to a percentage of the spot silver price that increases with lower mill silver head grades and lower silver prices, and decreases with higher mill silver head grades and higher silver prices, subject to certain ceiling and floor grades and prices. The increased production payments in lower silver price and/or lower silver grade environments increases the flexibility of Alexco to process lower grade ore and sustain mining operations during periods of lower silver prices and does so without limiting the upside opportunity of either Alexco or Silver Wheaton in higher price and grade environments.  As consideration, Alexco has agreed, subject to TSX and NYSE-MKT approval, to issue Silver Wheaton three million common shares of Alexco. The area of interest now includes properties currently owned by Alexco and properties acquired by Alexco in the future which fall within a one kilometre radius of existing Alexco holdings in the Keno Hill Silver District. 

On March 30, 2017, Silver Wheaton and certain of its subsidiaries provided a guarantee to the lenders under Primero Mining Corp.'s ("Primero") existing revolving credit facility (the "Primero Facility"), capped at a maximum of $81.5 million, plus interest, fees and expenses (the "Guarantee"). As a result of the Guarantee, Primero has obtained certain concessions from the lenders, including in respect of financial covenants and a six-month extension to the term of the Primero Facility. Primero will pay Silver Wheaton a fee of 5% per annum in connection with the Guarantee. Silver Wheaton believes that the Guarantee will assist Primero as it seeks to resolve the outstanding strike action, resume operations at the San Dimas mine, streamline its organization, and completes its strategic review process. However, there can be no assurance that the provision of the Guarantee or Primero's efforts will result in success in these initiatives.
