Dateline Resources Identifies Promising Carbonatite Targets at Colosseum Project

Dateline Resources Limited has announced significant progress in its Colosseum Project in California, identifying large carbonatite rare earth element (REE) targets through integrated geophysical datasets. Three distinct targets have been identified, with two targets ready for diamond drilling programs.

The drilling conducted in late 2025 confirmed mantle-derived REE signatures at the site, with the RC25-038 drill hole intersecting the margin of Target 1. This finding aligns with geophysical and geochemical data, supporting the presence of a carbonatite system similar to the nearby Mountain Pass carbonatite system.

The focus is now on an approved 12-hole diamond drill program targeting the Clark Mountain Fault Zone and Eastern Gravity anomalies. This approach aims to explore deeper into these anomalies, enhancing the understanding of the project's REE potential. Surface sampling indicates minimal oxidation, suggesting a well-preserved sulfide system, which bolsters confidence in the project's prospects.
