Mining Disputes Insights Series 2026

Mining projects and deals take shape through a fast‑moving mix of legal and commercial pressures, including cross‑border claims, constitutional and Indigenous law developments, and more frequent disputes across the project and transaction lifecycle.
Our Mining Disputes Insights Series highlights recent court decisions, legal developments and policy shifts that are influencing how capital is deployed, how transactions are structured, and how projects are advanced and defended when challenged. Each article offers focused insight on a specific pressure point or recent development, with an emphasis on practical consequences for mining companies, investors, and other market participants. Across the series, we explore questions that matter to both operational and deal teams.
