Acquisition Of New Silver Stream From Capstone's Cozamin Mine

VANCOUVER - Wheaton Precious Metals Corp. reported that its wholly-owned subsidiary, Wheaton Precious Metals International Ltd.has entered into a definitive Precious Metal Purchase Agreement with Capstone Mining Corp. in respect to the Cozamin Mine located in Zacatecas, Mexico.

"Wheaton has a long history with Capstone and Cozamin and welcomes the opportunity to bring back this first quartile mine into our portfolio of low-cost, long-life assets. Over the past few years, Capstone has conducted an extensive and successful exploration and drill program, which has significantly increased Cozamin's mine life.  We believe, as does Capstone, that the best is yet to come for Cozamin," said Randy Smallwood, President and Chief Executive Officer. "In addition, Wheaton is in advanced discussions with Capstone regarding a potential gold stream on their Santo Domingo project, which would provide additional near-term growth for the Company."

The underground Cozamin copper-silver-lead-zinc mine was commissioned in 2006 and has undergone two successful expansions since that time. The mill produces copper, zinc, and lead concentrates that are shipped to the port of Manzanillo for export to world markets. Exploration success has led to significant resource increases and excellent potential exists to continue this expansion. As part of the Silverstone Resources acquisition in 2009, Wheaton acquired a precious metals stream on Cozamin, which subsequently expired in 2017.
