Samarco targets pellet export comeback by 2028

That would also mark a significant rehabilitation for a company still defined by the 2015 tailings dam collapse that shut the operation and triggered one of Brazil’s most expensive environmental and legal cleanups. BHP’s latest filings show Samarco remains a non-operated joint venture owned 50-50 by BHP and Vale, underscoring how much the restart matters for both miners’ Brazilian portfolios and longer-term capital allocation.

The strategic bet comes as both owners face pressure to keep iron-ore businesses competitive while funding growth in copper and other transition-linked commodities. Vale has separately been pushing a copper expansion target to about 700,000 tonnes a year by 2035, while peers across the sector are using strong commodity pricing to reshape portfolios. MinRes’s move toward copper highlights that broader industry pivot, with capital chasing future-facing metals even as mature bulk commodities continue to fund dividends and buybacks.

For investors, Samarco’s comeback is less about a near-term earnings swing than about the durability of future supply and the reliability of execution. A successful ramp-up would support BHP and Vale’s Brazilian optionality, but any delay would keep a lid on expected cash flows and revive questions about operational risk, permitting and the pace of environmental remediation. In a market where high-grade iron ore and pellets command a premium, the 2028 target is as much a test of confidence as a production forecast.

The key watchpoints are whether Samarco can meet its restart milestones without incident, how quickly pellet exports recover against established producers, and whether demand for higher-grade raw materials stays firm enough to absorb additional supply. If the company delivers, it will not only reclaim market share but also complete one of mining’s most closely watched turnaround stories.
