“Company”) is pleased to announce that 2018 estimated production exceeded guidance as

detailed in the table below and provide production guidance for 2019 and the estimated

average annual attributable production over the five year period ending with 2023. Wheaton

will provide full production and financial details with the release of its 2018 fourth quarter and

“Our portfolio once again delivered a very strong performance in 2018 with p roduction

significantly exceeding our expectations for all precious metals ,” said Randy Smallwood,

Wheaton’s President and Chief Executive Officer. “The strong operational results cap a n

exceptionally successful year in which Wheaton strengthened its existing portfolio, added two

new streams from top-tier mines and settled our longstanding tax dispute , creating a

foundation for future growth. With the tax dispute behind us, we look forward to our company

once again being valued solely based on the virtues of our diverse portfolio of high-quality

assets which continue to deliver strong margins and the highest operating cash flow amongst

our peers.”

2018 Production Results

In 2018, production exceeded guidance primarily as a result of stronger than expected

production from the Salobo and Stillwater mines partially offset by weaker than expected

production from Peñasquito.

2019 and Long-Term Production Forecast

Wheaton’s estimated attributable precious metals production in 201 9 is forecast to be

approximately 365,000 ounces of gold, 24.5 million ounces of silver and 22,000 ounces of

palladium, resulting in gold equivalent production2 of approximately 690,000 ounces. For the

five year period ending in 2023, the Company estimates that average, annual gold equivalent

production will amount to 750,000 ounces.

In 2019, forecast silver production growth from Peñasquito is expected to be partially offset

by the change in the San Dimas stream from silver to gold as well as the cessation, in 2018,

of production from assets with fixed terms. Gold production in 2019 is expected to be slightly

below 2018 as a result of lower grades at Salobo due to mine sequencing (most pronounced

in the first quarter of 2019) being partially offset by increased attributable gold production

from the San Dimas mine. At Constancia, Hudbay Minerals Inc. (“Hudbay”) expects to begin

mining the Pampacancha satellite deposit later in 2019 , which has significantly higher

precious metals grades than what is currently being mined ; however, given the lack of a

definitive schedule at this point, f orecast gold production in 2019 does not include any

contribution from the Pampacancha deposit 3. Palladium production is expected to increase

in 2019 as the Company has its first full year of production from the Stillwater stream, which

was acquired in July of 2018.

Average production over the next five years is expected to increase primarily due to continued

production growth from Peñasquito, Constancia and Stillwater as well as the commencement

of the Voisey’s Bay stream in 2021. At Peñasquito, grades are expected to increase and the

addition of the pyrite leach plant should improve recoveries. At Constancia, production from

the Pampacancha deposit is included in Wheaton’s five year production average. Palladium

and gold production from Stillwater is expected to increase with the continued ramp up of the

Blitz project which is expected to reach full capacity in 2021. In addition, effective January 1,

2021, Wheaton will be entitled to receive from Vale an amount of cobalt equal to 42.4% of

the Voisey's Bay mine cobalt production . And lastly, Wheaton does not include any

production from Barrick Gold Corp.’s Pascua-Lama project or Hudbay’s Rosemont project in

its estimated average five-year production guidance4.

Tax Dispute Settlement impact on Fourth Quarter and Year End 2018 Results

As a reminder, on December 13, 2018, Wheaton announced that it had reached a settlement

with the Canada Revenue Agency (“CRA”) which provides for a final resolution of Wheaton’s

tax appeal in connection with the reassessment of the 2005 to 2010 taxation years. The terms

of the settlement provide that foreign income on earnings generated by Wheaton’s wholly-

owned foreign subsidiaries will not be subject to tax in Canada 5. In addition, the settlement

provided for Wheaton to increase fees for the services rendered to its foreign subsidiaries by,

first, including the third -party costs incurred by Wheaton directly associated with raising

capital that was used to fund investments made by its foreign subsidiaries in precious metals

purchase agreements and secondly, increasing the markup on costs incurred by the parent

company that are charged to the foreign subsidiaries, including attributable capital -raising

costs, from 20% to 30%.

The application of the settlement, after applying non-capital losses otherwise available, will

result in no additional cash taxes for the 2005 to 2010 taxation years. The application of the

principles of the settlement to the 2011 to 2017 taxation years is expected to result in cash

taxes payable of approximately $5 million. The net result is a cash outlay for all past taxation

years of approximately $10 million, including ancillary interest.

- 3 -

From an accounting perspective, share issue costs reduce share capital rather than being

deducted as an expense in the Statement of Earnings. Accordingly, the tax benefit related to

these costs, which are deducted for tax purposes over a 5-year period, is also recognized in

share capital. As a result, in recognizing the tax benefit of the non -capital losses utilized to

offset the additional taxable income arising from the settlement, a significant component of

which relate to share issue costs, we anticipate recording a deferred tax expense of

approximately $15 million in the Statement of Earnings with an offsetting deferred tax

recovery reflected directly in the Statement of Shareholders' Equity.

As we've previously indicated, the impact of the settlement will be reflected in the company's

financial results for the three months and year ended December 31, 2018. The total impact

of the settlement on Wheaton’s fourth quarter 2018 after-tax earnings, including current and

deferred taxes, ancillary interest and associated legal expenses is esti mated to be $30

million, of which approximately $15 million would relate to a deferred tax expense.

End Notes

1 Ounces produced represent the quantity of silver, gold and palladium contained in concentrate or

doré prior to smelting or refining deductions. Production figures and average payable rates are

based on information provided by the operators of the mining operations to which the silver, gold or

palladium interests relate or management estimates in those situations where other information is

not available. Certain production figures may be updated in future periods as additional information

is received.

2 Gold equivalent ounces for 2018 actual production and sales are calculated by converting silver to

a gold equivalent by using the ratio of the average price of silver to the average price of gold and by

converting palladium to a gold equivalent by using the average price of palladium to the average

price of gold, with all figures being as per the London Bullion Metal Exchange during 2018. Gold

equivalent production forecasts for 2018, 2019 and the five-year average are based on the following

commodity price assumptions: $1,300 / ounce gold, $16 / ounce silver, $1,350 / ounce palladium,

and $21 / pound of cobalt.

3 As per Wheaton’s precious metals purchase agreement with Hudbay, Wheaton is entitled to a

delay payment payable in gold ounces from Hudbay as a result of the delay in mining the

Pampacancha zone. The gold ounces delivered to Wheaton are included in the Co mpany’s

production guidance.

4 In preparing the long-term production forecast, Wheaton has considered the impact of Vale’s

recently announced approval of the Salobo III copper project, a brownfield expansion, which if

completed as proposed, would increase processing throughput capacity from 24 Mtpa to 36 Mtpa

once fully ramped up (the “Salobo Expansion”). However, readers are cautioned that Vale has not

finalized its mine plan and as such, Wheaton has not included any production growth as a result of

the Salobo Expansion.

5 The application of the settlement to years after 2010 (including the 2011 to 2015 taxation years

which are currently under audit) is limited to transfer pricing and will be subject to there being no

material change in facts or change in law or jurisprudence.
