Dateline Resources (ASX:DTR) has announced the expansion of the Music Valley Heavy Rare Earth Project in California, US, which now consists of 1,026 claims across 20,520 acres.
New claims were staked in 2025 with the Bureau of Land Management (BLM) confirming the lodgement of 969 claims across 19,380 acres.
The expanded Music Valley project now includes between 8 to 9km of the Pinto Gneiss unit, an area prospective for heavy rare earth elements.
Managing Director Stephen Baghdadi says that Music Valley “provides Dateline with district-scale exposure to a geological unit where heavy rare earth mineralisation was first documented by USGS geologists more than seventy years ago”.
“Our approach is to build on that historical work using modern exploration techniques,” Baghdadi says.
“Airborne geophysics, detailed mapping, and systematic sampling are already underway, allowing us to quickly generate and prioritise drill targets across the consolidated land position.”
Dateline is now working to expand the current program at Music Valley, with detailed geological mapping and rock chip sampling already having commenced.
Initial assays are expected later in Q1 2026.
Dateline also has a project-wide magnetics and radiometric survey underway. The company will review and interpret the results prior to planning its summer exploration program.
Dateline Resources is an Australian company focused on mining and exploration in North America.
