Ann: Colosseum REE Update, page-2

• Lab analysis confirms fenite outcrops within Colosseum claim boundary
• Multiple mantle derived rock outcrops observed over 1.6km
• Possibility of large underlying carbonatite occurrence
• Follow up program of detailed structural mapping, sampling, and petrography
underway
Dateline Resources Limited (ASX: DTR) (Dateline or the Company) is pleased to announce
the Company’s REE and carbonatite experts, Dr Anthony N. Mariano, PhD. and Mr Anthony
Mariano Jr, have reported their findings of the February 2022 field work to the Company.
The Mountain Pass REE mine is located ~10km south-east of the Colosseum mine. The
Mountain Pass REE mine is the only operating REE mine in the USA. Messrs Mariano have
been mapping, sampling and advising on REEs in the Mountain Pass area for over 50 years.
Commenting on the findings at Colosseum, Mr Mariano, said:
“The presence of lithologies associated with mantle derived systems such as the
Mountain Pass Alkaline-Carbonatite system have not only been confirmed to exist in the
Colosseum claim area, but additional previously unknown outcrop occurrences have
been found through this field investigation. The occurrence of multiple outcrops of these
lithologies at a distance of almost a mile apart within the Colosseum claims suggest the
possibility of a large underlying alkaline carbonatite occurrence”
