- Dateline Resources (DTREF, Financial) achieves 70% completion in its geophysical survey and 50% in geochemical sampling at the Colosseum Gold-REE Project.
- Project situated less than 10 kilometers from the Mountain Pass REE mine aims to bolster U.S. mineral supply.
- Initial assay results from collected samples expected in July 2025, with comprehensive data integration to guide future drilling.
Dateline Resources Limited (ASX: DTR, OTCQB: DTREF), an exploration company based in Australia, has announced significant advancements in its ongoing exploration program at the Colosseum Gold and Rare Earth Elements Project in California. The project is strategically located in the Walker Lane Trend of San Bernardino County, near the Mountain Pass REE mine, a significant global source of rare earth elements.
The magneto telluric (MT) geophysical survey is progressing well, with 119 out of 167 planned stations surveyed, marking a 70% completion rate. This survey aims to map deep subsurface resistivity, which could indicate the presence of REE-bearing mineralized structures. Preliminary resistivity inversions suggest promising contrasts that may correlate with subsurface geological features, with a comprehensive 3D inversion expected shortly after survey completion.
In tandem, the geochemical sampling program has reached 50% completion, having collected 599 out of 1,207 planned samples. These samples are being analyzed for a suite of rare earth elements and other geochemical markers, with the first assay results anticipated in early July 2025. This data will be crucial for refining drill targets as part of Dateline's "stacked evidence" methodology, integrating various geological data types for a comprehensive exploration strategy.
Managing Director Stephen Baghdadi expressed optimism about the ongoing progress and the potential of the Colosseum Project. He highlighted the strategic significance of the project in fulfilling U.S. initiatives aimed at strengthening domestic rare earth element production, thus reducing reliance on foreign mineral sources. The project’s advancements are expected to contribute significantly to the U.S. critical minerals supply chain.
