BHP Rises 2.9% After Testing New Copper Recovery Tech

BHP Group Limited ($BHP) rose 2.9% on Aug 20, 2026 after announcing a pilot with SiTration to test technology designed to recover copper from mining-impacted water at a historic Arizona site.

What BHP announced

BHP said a historic copper site in Arizona is serving as a real-world testing ground for technology that could help recover copper from mining-impacted water. The company is working with SiTration, an MIT spin-out backed by BHP Ventures, to deploy a two-stage pilot of SiTration’s copper recovery technology. The pilot will run on legacy mining water at BHP’s Copper Cities site in Arizona’s Globe-Miami mining district. In plain terms: BHP is testing whether a new process can pull usable copper out of water affected by past mining activity.

What it means for BHP

If the pilot performs as hoped, it could point to a new way to extract additional copper from existing, mining-impacted water streams rather than relying solely on traditional ore processing. That matters because it frames copper recovery as both a resource opportunity and a remediation-style project tied to legacy sites. Working with a venture-backed MIT spin-out also signals BHP’s interest in pushing earlier-stage technology into field conditions, where lab results meet operational reality. At minimum, the effort positions BHP to learn whether this approach can scale in a real mine-adjacent environment and how it fits into broader copper operations.
