Wheaton Precious Metals Corp. has finalized a major silver streaming agreement with BHP for the Antamina mine in Peru, securing long-term silver production rights through a $4.3 billion upfront payment that positions the company for enhanced cash flow and production stability.

Wheaton Precious Metals Corp. (NYSE: WPM) (TSX: WPM) announced that its subsidiary Wheaton Precious Metals International Ltd. has completed a silver stream transaction with BHP related to the Antamina mine in Peru. The agreement secures Wheaton's rights to 33.75% of payable silver until 100 million ounces are delivered, followed by 22.5% for the life of the mine. This transaction includes a substantial $4.3 billion upfront payment and ongoing payments equal to 20% of the spot silver price, positioning Wheaton to enhance long-term production and cash flow through one of the world's largest copper mines.
The importance of this deal lies in its scale and strategic positioning within the precious metals streaming industry. With a $4.3 billion upfront commitment, this represents one of the largest streaming transactions in recent history and demonstrates Wheaton's continued expansion in securing long-life, high-quality assets. The Antamina mine, as one of the world's largest copper operations, provides Wheaton with exposure to significant silver byproduct production from a well-established mining operation with proven reserves and infrastructure already in place.
This transaction matters because it strengthens Wheaton's portfolio of streaming agreements at a time when silver demand continues to grow across multiple sectors, including industrial applications, technology, and investment. By securing rights to a substantial portion of Antamina's silver production, Wheaton ensures predictable future revenue streams while minimizing the capital expenditures and operational risks typically associated with traditional mining operations. The structure of the deal—with initial higher percentage rights transitioning to long-term lower percentage rights—balances immediate production benefits with sustained long-term exposure.
The implications extend beyond Wheaton's immediate financial metrics to broader industry trends. Streaming companies like Wheaton provide mining operators like BHP with significant upfront capital that can be deployed for mine development, expansion, or debt reduction without diluting equity. This partnership model enables large-scale mining projects to proceed with reduced financial risk while giving streaming companies like Wheaton predictable, low-cost exposure to precious metals production. The transaction's scale suggests confidence in both the Antamina mine's long-term viability and silver's future market fundamentals.
For investors, this deal reinforces Wheaton's position as a leading precious metals streaming company with a growing portfolio of high-quality assets. The company's shares trade on multiple exchanges including the Toronto Stock Exchange, New York Stock Exchange, and London Stock Exchange under the symbol WPM. Additional information about the company is available through its corporate communications, though specific details about this transaction can be found in the original announcement available at https://ibn.fm/y20gR. This strategic move comes at a time when streaming agreements are becoming increasingly important in the mining finance ecosystem, providing alternative capital sources for mining companies while offering investors exposure to commodity prices with reduced operational risk.
