Daily Mining Update (May 24, 2026) — A major Chilean court decision has reopened scrutiny on a key water-supply permit at one of the world’s largest copper mines, while drill results and corporate transactions continue to shape the precious-metals and critical-minerals space.
Chile copper: Collahuasi expansion permit overturned
- Chile’s Second Environmental Court annulled the environmental authorization for Collahuasi’s desalination-plant project, citing concerns tied to Indigenous communities and marine impacts, and ordered Chile’s environmental authority (SEA) to reassess parts of the project. MINING.COM
- Collahuasi is owned by Anglo American, Glencore, and a Japanese consortium led by Mitsui; MINING.COM notes it is the world’s sixth-largest copper mine and produced more than 404,000 tonnes of copper last year. MINING.COM
Silver exploration: GR Silver reports “best ever” San Marcial drill result

Context: Permitting and financing remain key catalysts
- Regulatory decisions (like water and environmental permits) can materially change timelines and capital requirements for large copper operations, while junior explorers often rely on staged financings and new asset deals to keep programs moving.
