DOJ defends Dateline Colosseum mine rights

The U.S. Department of Justice filed an opposition motion on July 6, 2026, in the U.S. District Court for the Central District of California, defending the United States — National Park Service's April 2025 recognition of Dateline Resources Limited's Valid Existing Rights at the Colosseum Mine. The DOJ argues that the existing Plan of Operations remains operative and that the NPCA's challenge is unlikely to succeed. Dateline Resources, as an intervenor, supports the government's position. The case was initiated by the National Parks Conservation Association against the DOI and NPS.
