COMPANY ACQUISITION HISTORY
     NOTES TO TIMELINE
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 $4.24 per ounce, subject to an annual inflationary factor.
3. 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.
4. In March 2017, the Company amended its silver purchase agreement with Alexco Resource Corp. (“Alexco”) to make the production payment a function of the silver head grade and silver spot
    price in the month in which the silver is produced. In addition, the area of interest was expanded to include properties currently owned by Alexco and properties acquired by Alexco in the future
    which fall within a one kilometer radius of existing Alexco holdings in the Keno Hill Silver District. As consideration of the amendments, Alexco issued 3,000,000 shares to Wheaton Precious
    Metals.
5. Wheaton Precious Metals only has the rights to silver contained in concentrate containing less than 15% copper at the Aljustrel mine.
6. Comprised of $11 million allocated to the silver interest upon the Company’s acquisition of Silverstone Resources Corp. in addition to a contingent liability of $32 million, payable upon the
    satisfaction of certain conditions, including Pan American receiving all necessary permits to proceed with the mine construction.
7. Definitive terms of the agreement to be finalized.
8. The upfront consideration is net of the $373 million cash flows received relative to silver deliveries from the Lagunas Norte, Veladero, and Pierina mines.
9. The upfront consideration is currently reflected as a contingent obligation, payable on an installment basis to partially fund construction of the Rosemont mine once certain milestones are
    achieved, including the receipt of key permits and securing the necessary financing to complete construction of the mine.
10. 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. Should there be a delay
    in achieving completion or mining the Pampacancha deposit beyond the end of 2018, Wheaton Precious Metals would be entitled to additional compensation in respect of the gold stream.
11. Subject to an increase to $9.90 per ounce of silver and $550 per ounce of gold after the initial 40 year term.
12. Vale has completed the expansion of the mill throughput capacity at the Salobo mine to 24 million tonnes per annum (“Mtpa”) from its previous 12 Mtpa. If actual throughput is expanded above
    28 Mtpa within a predetermined period, and depending on the grade of material processed, Wheaton Precious Metals will be required to make an additional payment to Vale based on a set fee
    schedule ranging from $113 million if throughput is expanded beyond 28 Mtpa by January 1, 2036, up to $953 million if throughput is expanded beyond 40 Mtpa by January 1, 2021.
13. Upfront payment consisted of $800 million cash & the amendment of the 10mil Wheaton Precious Metals common share purchase warrants previously issued to Vale in connection with the
    Sudbury precious metal purchase agreement which expire on Feb. 28, 2023 to reduce the strike price from $65 to $43.75 per common share. The amendment to these warrants was valued at
    $29 million using a Black-Scholes option pricing model.
14. Includes Coleman, Copper Cliff, Garson, Stobie, Creighton, Totten & Victor gold interests. Upfront payment consisted of $570 million cash plus 10 million Wheaton Precious Metals common
    share purchase warrants with a $65 strike and 10 year term.

                                                                                                                                                                               Appendix            32

23. 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
24. Wheaton International will pay a total cash consideration of US$110M, US$38M of which is payable within six months subject to customary conditions, and the remaining portion of which is
    payable during the construction of the MDZ project subject to receipt of required permits and licenses, sufficient financing having been obtained to cover total expected capital expenditures, and
    other customary conditions. The stream is effective July 1, 2020. Production payment is set at 18% of the gold and silver spot price until the value of the upfront cash consideration is reduced to

25. The Company has amended the Minto PMPA such that the per ounce cash payment per ounce of gold delivered will be 75% of the spot price of gold for each ounce of gold delivered under the
    Minto PMPA. This amended pricing will end on the earlier of (i) 14 months after the first delivery is due; or (ii) once 11,000 ounces of gold have been delivered to the Company. Once this
    amended pricing ends, the per ounce cash payment per ounce of gold delivered will be $325, subject to an increase in periods where the market price of copper is lower than $2.50 per pound.

RESOLUTION OF THE CANADIAN TAX DISPUTE
 REASSESSMENT FOR 2005-2010 SETTLED ON DECEMBER 13, 2018
Background10 ▪     CRA reassessed Wheaton in September 2015 for tax years 2005-2010:
                   • CRA’s position was that income earned by Wheaton’s foreign subsidiaries (Wheaton
                     International) outside of Canada from mines located outside of Canada should be taxable in
                     Canada on the basis of transfer pricing
                   • Total potential liability for 2005 - 2017 was over US$1bn
Settlement10   ▪   Foreign income on earnings generated by Wheaton International will not be subject to
                   tax in Canada under transfer pricing rules10
               ▪   The service fee charged by Wheaton for the services provided to Wheaton International will be
                   adjusted to include capital-raising costs and the mark-up will be increased from 20% to 30%.
                   • This additional service fee will result in increased income generated by Wheaton in Canada
                      that is subject to Canadian tax.
               ▪   The transfer pricing principles reached in the settlement principles will apply to taxation years
                   after 2010 subject to there being no material change in facts or change in law or jurisprudence
               ▪   Total expenses of $29 million in respect of the 2005-2017 taxation years reflected in the Q4
                   2018 Statement of Earnings and includes a non-cash income tax expense of $16 million
                   • Net cash expense of $13 million comprised of (i) $4 million of current income taxes; (ii) $4
                      million of interest and penalties; and (iii) $5 million of professional fees.
        The tax settlement resulted in less than $10 million in cash taxes & interest through 2017
