Priority targets confirmed in the field
SAN BERNARDINO, CA / ACCESS Newswire / June 22, 2026 / Dateline Resources Limited (ASX:DTR)(OTCQB:DTREF)(FSE:YE1) (Dateline or the Company) is pleased to announce that it has added an additional 66 claims covering ~1,300 acres to the Music Valley Heavy Rare Earth Project (Music Valley), located in Riverside and San Bernardino Counties, California, USA.
The new claims are in the NW of the project area, located approximately six kilometres southeast of the town of Twentynine Palms. The new claims cover an extension of the NW geophysical target.
Field mapping and sampling by the Company's HREE and structural consultants, Tony Mariano Jr and Russell Mason, identified outcropping zones of the targeted Pinto Gneiss unit that correlates with the Thorium anomaly identified in the geophysical surveys.
The Pinto Gneiss unit was also identified in outcrops in the southern target area within the claims acquired by the Company in February 2026.
All priority prospects are located outside the 252 claims that are the subject of court proceedings.
Dateline's Managing Director, Stephen Baghdadi, commented:
"The addition of these claims further enhances the scale and strategic position of the Music Valley Project, while securing ground that hosts an extension of one of our priority geophysical targets.
"The identification of extensive outcropping Pinto Gneiss within both the northwest and southern target areas is an encouraging development. This unit is recognised as the principal host to heavy rare earth mineralisation in the district and was the focus of historic USGS sampling that returned high-grade HREE results.
"As mapping and sampling continue, we are rapidly advancing our understanding of the project and building the geological framework required to support a maiden drill program."
New Claims
Dateline has staked 66 claims for ~1,300 acres in the northwest of the Music Valley HREE Project, securing district-wide control of the area. The Company has now either acquired or staked and registered claims over all the available land in the area.
Field Mapping Program
Dateline's HREE and structural consultants, Tony Mariano Jr and Russell Mason, have undertaken field mapping across two of the three geophysical targets.
At the Northwest target area, there are extensive exposures of outcropping rock, with little to no cover material in this area. The biotite-rich Pinto Gneiss unit, which was identified by the United States Geological Survey (USGS) as the host unit for HREE mineralisation in the area, was mapped in several different locations in this area.
The southern target area, which is located within the tenements acquired by Dateline in February 2026, was also visited by Mariano Jr and Mason. The Pinto Gneiss in this area seems to have a number of sub-units with different geological properties.
