Dateline Resources (ASX:DTR) has completed a geophysical interpretation at its Music Valley Heavy Rare Earth Element Project in California, identifying three priority prospects for follow-up exploration.
The magnetic and radiometric survey interpretation by Mitre Geophysics highlights ‘significant’ structural detail across the 20,520 acre project area.
It also shows thorium-rich domains appearing as the best proxy for heavy rare earth element (HREE) mineralisation, with local faulting and contact with younger diorite intrusions identified as the most prospective targets for exploration.
Dateline notes that future mapping, sampling, and drilling campaigns will focus on the coincidence of these features.
Managing Director Stephen Baghdadi says Music Valley has always had the makings of a “significant heavy rare earth district”.
“The interpretation has identified a series of structurally complex zones associated with elevated thorium signatures and favourable Pinto Gneiss geology,” Baghdadi says.
“These are precisely the types of settings where we would expect rare earth mineralisation to be concentrated.
“Rather than searching across a large land package, we are now focusing on a small number of highly prospective target areas.”
All three priority prospects are located outside the 252 claims currently subject to court proceedings, and are therefore unaffected by current litigation.
Ground truth mapping of the priority prospects is currently underway, with a larger-scale rock chip sampling program planned as part of the campaign.
The company expects further information on these priority prospects in the next two weeks.
Dateline Resources is focused on mining and exploration in North America.
