Dateline Resources says a gravity survey at its Colosseum gold claims in California has revealed multiple rare earth drill targets. 

The study has highlighted a gravity high, about 1km from the Colosseum open pit, which strikes north-northwest over 2,000m and varies in width between 200m and 450m.

Dateline Resources (ASX:DTR) says the density range achieved in the unconstrained 3D inversion is similar to the mineralized carbonatite at the nearby Mountain Pass Rare Earth Mine.

Just 10kms away, Mountain Pass is the richest rare earth mine in the world and is the only operating rare earth mine in the USA.

Potential for underground access

The company believes there’s potential to develop underground access to the target from the base of the Colosseum open pit mine.

“This is a very encouraging result,” MD Stephen Baghdadi said.

“The gravity data confirms there are several areas of interest and there exists the potential for more than one carbonatite dyke within the claim boundary,”

“The first zone targeted for drilling is ~2km in strike and trends NNW.”

The target is parallel to a thorium signature on the west and mantle derived rocks on the east, with an estimated depth of 150-250m below the surface.

“Other targets are north of the pit and are immediately adjacent to fenitised outcrops,” he said.

Drill testing plans underway

Dateline will now develop an initial drilling campaign to fully assess the strike extent of the dense unit to determine if it is a rare earth bearing carbonatite.

It will be the first systematic exploration program across the claims in more than 25 years.
