WHEATON PRECIOUS METALS ANNOUNCES PROPOSED PRECIOUS

METALS STREAM WITH CALDAS GOLD ON THE MARMATO PROJECT

Wheaton Precious Metals™ Corp. (“Wheaton” or the “Company”) is pleased to announce that

its wholly -owned subsidiary, Wheaton Precious Metals International Ltd . (“Wheaton

International”) has signed a non-binding term sheet with Caldas Gold Corp. ( “Caldas Gold”)

(TSX-V: CGC) to enter into a Precious Metals Purchase Agreement (the “Precious Metal s

Stream”) for the Marmat o Project located in Col ombia. The Marmato Project comprises an

operating Upper Mine and the Marmato Deeps Zone (“MDZ”) development, both of which are

covered by the Precious Metals Stream.

“Wheaton is excited to partner with Caldas Gold in developing the Marmato Project. The

strength and potential upside of this project was especially apparent during our onsite due

diligence trip, prior to t ravel restrictions being put into place,” said Randy Smallwood,

President and Chief Executive Officer of Wheaton Precious Metals. “We remain unwavering

in our focus on delivering the highest quality portfolio of precious metals production to our

shareholders through our top tier asset base, strong organic growth profile and acquisition of

accretive growth opportunities such as Marmato. As can be seen, Wheaton continues to be

very active on the corporate development front despite limitations resulting from t he current

global COVID-19 pandemic.”

Upon entering into the Precious Metals Stream, Wheaton International will purchase 6.5% of

the gold production and 100% of the silver production until 190,000 ounces of gold and 2.15

million ounces of silver have been delivered, after which the stream drops to 3.25% of the gold

production and 50% of the silver production for the life of mine. Under the proposed Precious

Metals Stream, Wheaton International will pay a total cash consideration of $110 million1, $38

million of which is payable upon closing 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. In addition, Wheaton International will make ongoing payments

equal to 18% of the spot gold and silver price until the uncredited portion of the upfront

payment is reduced to zero, and 22% of the spot gold and silver price thereafter. The entering

into of the Precious Metals Stream is subject to , among other matters, the negotiation and

completion of definitive documentation.2

As part of the Precious Metals Stream, Caldas Gold has agreed to provide funding to support

the local communities around the Marmato Project.

About the Marmato Project

Caldas Gold’s Marmato Project comprises the existing producing underground gold and

silver mine in the Upper Zone, the existing 1,200 tonnes per day (“tpd”) processing plant and

the area encompassing the MDZ. The current mine has been in operation since 1991. The

Marmato Project has excellent infrastructure as it is located by the Pan American Highway

with access to Medellin to the north and Manizales to the south, and has access to the

national electricity grid, which runs near the property.

The Preliminary Economic Ass essment completed in 2019 charts a path for expansion of

mining operations at the Marmato Project, ultimately comprised of two distinct operations,

the existing Upper Mine operation and the MDZ project, which sits directly below the Upper

Zone vein system. In 2019, the Upper Mine produced 25,750 ounces of gold and 39,560

ounces of silver . Implementation of a mine optimization program in the Upper Mine is

expected to increase gold production starting in 2020 and reduce total cash costs per ounce.

A Prefeasib ility Study, currently in process and expected to be completed mid -2020, is

focused on the development of mining operations in the MDZ, including construction of an

additional 4,000 tpd plant and new dry stack tailings storage facilities. Mechanized mining ,

using an underground longhole stoping method, in the MDZ is expected to further increase

production commencing by 2023.
