Dateline Resources Files Motion Seeking Stay of Colosseum Injunction
Dateline Resources and Colosseum Rare Metals filed a motion in the US District Court for the Central District of California seeking a stay of the preliminary injunction affecting operations at the Colosseum project while an appeal is heard.
Dateline Resources Limited and its subsidiary Colosseum Rare Metals, Inc. have asked a US court to pause the preliminary injunction that currently prevents company operations within the Mojave National Preserve. The filing is intended to allow work at the Colosseum Gold and Rare Earth Project to resume while the appeal proceeds, but the source does not state that a stay has been granted or that operations have restarted.
Dateline and Colosseum Rare Metals filed the motion on 18 September 2026 (US time) in the US District Court for the Central District of California. The application seeks a stay pending appeal of an order issued on 10 August 2026.
That order granted a preliminary injunction and barred operations by the company within the Mojave National Preserve. The underlying proceedings were brought by the National Parks Conservation Association against the US Government.
On September 11, 2026, a Department of Justice trial attorney and Dateline’s attorney notified counsel for the National Parks Conservation Association that the Department of Justice, Colosseum Rare Metals and parent company Dateline Resources intended to seek a stay pending appeal.
A request of this type is initially considered by the judge who issued the injunction. The motion will be heard by Judge Christina A. Snyder, who issued the 10 August 2026 order.
Dateline describes the court filing as the first step towards resuming work at Colosseum. However, the announcement provides no outcome for the motion and does not say that the preliminary injunction has been lifted, paused or otherwise changed.
Dateline Resources Limited is identified in the announcement under the trading codes ASX:DTR, OTCID:DTREF and FSE:YE1. The company is focused on mining and exploration in North America and states that it owns 100% of the Colosseum Gold-REE Project in California.
The Colosseum Gold Mine is located 10km north of the Mountain Pass rare earth mine in East San Bernardino County, California. Dateline states that drill testing of the project’s HREE potential has commenced and that a Bankable Feasibility Study was completed in May 2026.
The company also states that it acquired the Argos Strontium Project in San Bernardino County and consolidated the Music Valley Heavy Rare Earth Project in Riverside and San Bernardino Counties in March 2026.
Dateline says its forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially. The announcement identifies future market conditions, changes in the regulatory environment and the behaviour of other market participants as examples. It also states that the company cannot give any assurance that those statements will prove correct.
