Wheaton completes $4.3B silver streaming deal with BHP for Peru's Antamina mine

Wheaton Precious Metals' subsidiary finalized a $4.3 billion silver streaming agreement with BHP for the Antamina mine in Peru. Starting April 1, 2026, Wheaton will purchase 33.75% of the mine's payable silver until 100 million ounces are delivered, then 22.5% for the mine's life. Wheaton pays 20% of the silver spot price on delivery, providing long-term exposure to silver with lower risk than traditional mining. This deal strengthens Wheaton's portfolio and cash flow potential.
