BHP unlocks billions from Antamina silver stream as copper-led strategy gains momentum

Mining heavyweight BHP Group Ltd (ASX: BHP) has reinforced its strategic pivot toward future-facing commodities, announcing a landmark US$4.3 billion silver streaming agreement tied to its share of production from Peru’s Antamina mine. The transaction, among the largest precious metals streaming deals globally, signals a deeper reshaping of the company’s portfolio as copper becomes an increasingly dominant earnings driver.

Under the agreement, BHP will receive an upfront payment of US$4.3 billion from Wheaton Precious Metals in exchange for delivering a portion of future silver output attributable to its 33.75% stake in Antamina, while retaining full exposure to copper, zinc, and lead production. 

The structure allows BHP to monetise a non-core by-product commodity while preserving leverage to base metals that are central to electrification, infrastructure development, and energy transition demand.

Chief Executive Officer Mike Henry described the deal as a disciplined step in extracting additional value from a long-standing asset, noting that Antamina has historically delivered strong copper performance and continues to remain a cornerstone of the company’s base metals portfolio. 

Chief Financial Officer Vandita Pant added that the upfront proceeds, combined with recent capital initiatives, could unlock more than US$6 billion in cash, strengthening financial flexibility and supporting long-term value creation initiatives.

Copper takes centre stage in BHP’s earnings profile

The timing of the transaction reflects a broader transformation underway within BHP. For the first time in its history, copper contributed the majority of group earnings, underscoring how demand linked to electrification, renewable energy systems, and expanding power infrastructure is reshaping the mining sector’s profit landscape.

Industry analysts increasingly view diversified miners through the lens of their exposure to transition metals rather than traditional bulk commodities alone. With copper production continuing to expand and global supply growth constrained by permitting challenges and declining grades in mature districts, long-life operations such as Antamina remain strategically important.

Management commentary has also pointed to a shift in long-term demand geography, with India emerging as a key growth engine alongside China, reflecting evolving global industrial dynamics and infrastructure expansion trends.

Why the streaming deal matters

Streaming agreements are commonly used in the mining sector as a financing tool that converts future metal production into immediate capital. In BHP’s case, the structure effectively unlocks value from silver, which is produced as a by-product at Antamina, without increasing debt levels or affecting existing customer contracts. 

The agreement will see BHP deliver the equivalent of 33.75% of Antamina’s silver production initially, later reducing to 22.5% after a defined delivery threshold is met, while Wheaton pays ongoing transfer payments tied to silver prices. 

For shareholders, the strategic rationale is straightforward. The company receives substantial upfront capital that can be redeployed into higher-return growth projects, including copper expansions and future-facing commodities, while maintaining operational exposure to the mine’s primary revenue streams.

Market reaction and strategic outlook

Shares in BHP have strengthened following the announcement, reflecting market approval of the company’s capital management strategy and its clearer alignment with metals expected to benefit from long-term electrification trends.

The combination of stronger copper earnings contribution, proactive portfolio optimisation, and disciplined capital recycling suggests the miner is entering a new phase where growth is less dependent on bulk commodity cycles and increasingly linked to global energy transition demand.

Looking ahead, the Antamina streaming transaction highlights how large diversified miners are reshaping portfolios not only through acquisitions and expansions but also through innovative financial structures that release capital while maintaining operational leverage. 

For BHP, the message is clear: copper and future-facing metals are now central to the company’s growth narrative, and capital allocation decisions are increasingly being designed around that strategic shift.
