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
COMPANY ACQUISITION HISTORY NOTES TO TIMELINE 15. Comprised of $16 million paid to date and $138 million to be payable on an installment basis to partially fund construction of the mine. Following the delivery of certain feasibility documentation or after December 31, 2017 if the feasibility documentation has not been delivered to Wheaton Precious Metals by such date, Wheaton Precious Metals may elect not to proceed with the agreement or not pay the balance of the upfront consideration and reduce the gold stream percentage from 10% to 0.909% and the silver stream percentage from 50% to nil. If Wheaton Precious Metals elects to terminate, Wheaton Precious Metals will be entitled to a return of the amounts advanced less $2 million which is non-refundable on the occurrence of certain events. If Wheaton Precious Metals elects to reduce the streams, Gold X Mining Corp. may return the amount of the deposit already advanced less $2 million to Wheaton Precious Metals and terminate the agreement. 16. Glencore owns 33.75% of the Antamina mine through a joint venture. Wheaton Precious Metals is entitled to Glencore’s portion of the silver production. 17.
