Overview
About Dateline Resources
Dateline Resources Limited (ASX: DTR; OTCQB: DTREF) is an Australian gold and rare-earths development company headquartered in Sydney, focused on the 100%-owned Colosseum Gold-Rare Earths Project in San Bernardino County, California, approximately 10 kilometres north of MP Materials’ Mountain Pass rare-earth mine. The company has completed a bankable feasibility study targeting gold production from Colosseum, while pursuing the project’s rare-earth potential.
Mapping, geophysics and geochemistry have confirmed a geological link between Colosseum and Mountain Pass, and in 2025 the U.S. Department of the Interior publicly described Colosseum as America’s second rare earth mine, highlighting neodymium-praseodymium magnet-metal potential. Dateline has expanded its U.S. footprint with additional mining claims and advanced development plans, positioning Colosseum as a strategic domestic asset within efforts to rebuild United States rare-earth and gold supply.
