Dateline Resources Limited (ASX: DTR, OTCQB: DTREF, FSE: YE1) is focused on the development of the Colosseum Gold-Rare Earths Project in San Bernardino County, California, USA.

Colosseum was previously mined for gold between 1988-1993 with 344,000 ounces out of a 1.1Moz resource recovered before Barrick Gold Corporation closed the mine due to a low gold price of US$340 per ounce.

Nearly 30 years later, Dateline acquired the dormant Colosseum Project from Barrick, undertaking a significant data verification and digitization process before commencing a large-scale exploration program.

Exploration by Dateline successfully confirmed the remnant mineral resources and then further added to them, with the current JORC-2012 mineral resource standing at 1.1Moz of gold.

A Scoping Study in 2024, utilizing 5 years of actual production data, resulted in excellent economic results that are currently the focus of a Bankable Feasibility Study. Pending a positive BFS outcome, the Company aims to commence construction of a 2Mtpa processing plant in 2026 and generate 75,000+ ounces of gold per annum from Colosseum.

In addition, Dateline’s rare earth experts have confirmed the geology, geophysics and geochemistry at Colosseum is genetically linked to Mountain Pass, located 10km to the south of Colosseum. Mountain Pass is currently the only operating rare earth mine in the US. Dateline is finalizing plans for a large-scale exploration drilling campaign at Colosseum in 2025.

In September 2025, Dateline moved to 100% ownership of the Argos Strontium Project, also located in San Bernardino County. Argos contains the largest known strontium deposit in the United States. With uses including magnets for EVs and defence applications, Argos is a strategic asset for the company.
