Wheaton Precious Metals Finalizes Silver Stream Agreement with BHP for Antamina Mine
On April 1, 2026, Wheaton Precious Metals Corp. announced a pivotal advancement in its operational strategy with the successful closure of a silver stream agreement with BHP Group Limited. This agreement pertains specifically to the Antamina Mine located in Peru, marking a notable occasion for both companies involved in the precious metals sector.
Wheaton's wholly-owned subsidiary, Wheaton Precious Metals International Ltd. (WPMI), will now purchase the equivalent of 33.75% of the payable silver produced at Antamina. This arrangement will remain in place until a cumulative total of 100 million ounces of silver has been delivered. Thereafter, WPMI will secure rights to purchase 22.5% of the payable silver for the remaining life of the mine. The pricing mechanism involves a fixed payable factor set at 90%, ensuring predictable returns for Wheaton.
In the context of this agreement, WPMI has committed an upfront payment totaling USD 4.3 billion. Furthermore, for each silver ounce delivered, WPMI will provide ongoing payments equivalent to 20% of the current spot price of silver. This investment underscores Wheaton's strategy of leveraging stable cash flows while maintaining a lower risk profile compared to conventional mining operations.
For investors, this transaction exemplifies Wheaton’s commitment to enhancing its profitable portfolio of long-life, low-cost assets. The Company’s business model effectively allows stakeholders to gain from rising commodity prices while mitigating risks typically associated with more traditional mining ventures. As highlighted by their focus on high cash operating margins, Wheaton continually seeks to sustain a competitive dividend and pursue opportune acquisitions that align with its growth objectives.
Moreover, whey companies engage in partnerships especially within the mining industry, best practices surrounding environmental sustainability and social responsibility take on added significance. Wheaton has made it a priority to implement strong environmental, social, and governance (ESG) measures, reaffirming its intention to contribute positively to the communities within which it operates. This not only fosters goodwill but also improves operational sustainability in the long term.
This new silver stream agreement with BHP comes just a few months after Wheaton had previously announced an expansion of its silver streaming portfolio, indicating an ongoing trend of aggressive growth fueled by sound business practices. The details of this strategic acquisition were elaborated upon in a previous press release dated February 16, 2026, where Wheaton highlighted the broader implications of its partnership with BHP and the anticipated benefits from expanded silver production.
In essence, this agreement represents more than just a transactional milestone; it is a forward-looking pivot for Wheaton. By aligning with a major player like BHP at a renowned site such as Antamina, Wheaton accelerates its pathway to solidifying its leadership position in the precious metals streaming sector. As both companies navigate the complexities of global markets and commodity fluctuations, their partnership stands as a testament to aligning shared interests for mutual benefit.
The industry can expect that developments from this strategic alignment will positively influence Wheaton's production metrics and overall cash flow profile. Given the volatile nature of commodity markets, managing risks effectively while capitalizing on synergistic agreements like this is crucial.
As Wheaton Precious Metals continues to forge ahead, stakeholders, investors, and market watchers alike will be keenly observing how this silver stream transaction unfolds, particularly in light of its potential to significantly bolster Wheaton's competitive edge and market sustainability. The Company’s strategic foresight and its ability to execute such complex agreements will likely serve as a model within the realm of precious metals streaming— a field that promises both challenges and opportunities for those who navigate it wisely.
