Capstone Announces Closing of $150 Million Silver Stream Agreement with Wheaton Precious Metals; Achieves Net Cash Position

(All amounts in US$ unless otherwise specified)

VANCOUVER, British Columbia--()--Capstone Mining Corp. (“Capstone” or the “Company”) (TSX:CS) is pleased to announce that it has closed the previously announced Precious Metals Purchase Agreement (the “Stream Agreement”) with Wheaton Precious Metals International Ltd., a wholly-owned subsidiary of Wheaton Precious Metals Corp. (collectively, “Wheaton”). All conditions to complete the Stream Agreement have been fulfilled and Capstone has received $150 million from Wheaton for 50% of the silver production until 10 million ounces have been delivered, thereafter dropping to 33% of silver production, for the life of mine from the Company’s Cozamin Mine in Zacatecas, Mexico (“Cozamin”). Wheaton will make ongoing payments equal to 10% of the spot silver price at the time of delivery for each ounce delivered to them.

“With a current net cash position, this transaction gives Capstone one of the strongest balance sheets amongst its peers,” said Darren Pylot, President & CEO of Capstone. “Additionally, we are expecting around one billion dollars of after-tax operating cash flow over the next three years in the current $4.00 copper price environment. We look forward to strengthening our partnership with Wheaton as we continue advanced discussions for a potential gold stream on Santo Domingo.”

For more details on the Stream Agreement, please refer to Capstone’s news release of December 11, 2020 available at https://capstonemining.com/news/2020/default.aspx.
