Further to BHP’s announcement on 17 February 2026, BHP, through a wholly owned subsidiary, has completed its long-term silver streaming transaction with Wheaton Precious Metals International Ltd. (a wholly owned subsidiary of Wheaton Precious Metals Corp.) (Wheaton) relating to BHP’s share of silver production from the Antamina Mine in Peru.

Under the silver streaming agreement (the Agreement), BHP has received total upfront consideration of US$4.3 billion (Upfront Consideration) from Wheaton.

In return for the Upfront Consideration and ongoing production transfer payments (payable at 20% of the spot silver price per ounce of silver delivered pursuant to the Agreement), BHP will deliver to Wheaton the equivalent of 33.75% of the silver produced by Antamina (subject to a fixed payable rate of 90%).  After 100 million ounces of silver have been delivered to Wheaton, the stream will be reduced and BHP will deliver the equivalent of 22.5% of silver produced by Antamina over the remaining life of mine. The settlement of the stream is completed via metal credits with no physical delivery of silver to Wheaton.
