Gold mining and exploration company Dateline Resources (DTR) has appointed rare earth elements (REE) and carbonatite experts Dr Anthony N. Mariano, PhD and Anthony Mariano Jr to advise on REE exploration of the Colosseum mine area.

Dr Mariano and Mr Mariano Jr are mineral exploration geologists who specialise in the geology and mineralogy of rare elements on a world level.

The duo have extensive experience with the Mountain Pass mine located 10 kilometres to the south of the Colosseum mine in south-eastern California, and they have been mapping, sampling and advising on REEs in the Mountain Pass-Colosseum area for over 50 years.

“Realising the close relationship between mineralised carbonatite bodies at the Mountain Pass mine and their genetically related alkaline rocks, the need for further exploration in the Mountain Pass-Colosseum corridor is obvious and cannot be over emphasised,” said Dr Mariano.

The company had retained the pair to undertake a brief field program to measure radiometric readings and collect samples for analyses following a review of USGS geophysics data indicating a marked increase in radioactivity relative to normal crustal rocks.

A brief field investigation was conducted in September 2021 to measure ground radiometric readings and observe the rock units associated with the trends within the Colosseum claims.

Further surface geological mapping, rock sampling and petrographic analyses will be completed in Q2 2022, with a structural geologist contracted to provide detailed structural mapping of the Colosseum claims.

In order to ensure the REE program is executed to the highest level, Dateline has retained the Marianos as senior REE expert advisers to the exploration program.

Dateline said it has raised working capital of $810,000 via loans and a placement, which it will use to fund its exploration program.

DTR shares were up 12.5 per cent, trading at 13.5 cents as of 1:17 pm AEST.
