High-Resolution Airborne Survey Completed at
Music Valley HREE Project
Highlights
• 2,172 line kilometre survey completed: The helicopter-borne magnetic and radiometric survey
has been completed over the expanded Music Valley HREE Project area, ahead of schedule.
• Low level = high resolution: The survey was completed on 50 metre line spacings at a flight
height of 30 metres, which will generate a high-resolution dataset for processing and interpreting.
• Data Analysis Underway: The survey data has been provided to Mitre Geophysics for
processing, inversions and analysis.
• Mapping and Sampling Underway: Dateline’s consulting REE and structural geology specialists
are in the field, mapping and rock chip sampling across the expanded Music Valley HREE Project
area.
Dateline Resources Limited (ASX: DTR, OTCQB: DTREF, FSE: YE1) (Dateline or the Company) is
pleased to announce the completion of the geophysical survey covering the Music Valley Heavy Rare
Earth Project (Music Valley), located in Riverside and San Bernardino Counties, California, USA.
The magnetic and radiometric survey included all of the 20,520 acres highlighted in the expanded
Music Valley Project announcement (ASX Announcement 11 March 2026).
The helicopter-borne survey was undertaken by Precision GeoSurveys based in Reno, Nevada. The
2,172 line kilometre survey was flown on 50m spaced lines at a height of 30m using state of the art
equipment.
Dateline’s Managing Director, Stephen Baghdadi, commented:
“Completion of the Music Valley airborne survey represents a step in Dateline’s systematic
exploration of this emerging heavy rare earth district. The data will now be processed and integrated
with field mapping and rock chip sampling to refine the Company’s geological model and guide the
next phase of exploration.”

Dateline Secures Second Rig to Fast-Track Colosseum Program

Highlights
• Second rig acquired: Dateline has purchased a diamond drill rig to supplement the contracted
rig currently drilling the rare earth targets at Colosseum.
• Rig mobilised to site: The rig has been mobilised to site and has undergone final safety
inspections before commencing drilling.
• Gold and REE targets: The two diamond rigs will work in tandem to complete the regional gold
and REE targets as well as test the northeast extension of the North Pipe mineralisation.
Dateline Resources Limited (ASX: DTR, OTCQB: DTREF, FSE: YE1) (Dateline or the Company) is
pleased to announce the arrival and commencement of drilling of the second diamond drill rig at
Colosseum. Given the expected scale of the drilling program ahead, Dateline took the opportunity
to acquire a suitable track-mounted drill rig that is capable of drilling holes to 1200 metres depth.
The second rig will work in tandem with the Major Drilling rig on site to complete the 12-hole REE
program before being deployed to test the other gold and REE targets within the project area.
Depending on timing and requirements, the second rig may also be mobilised to undertake drilling
programs at Music Valley and/ or Argos.
Dateline’s Managing Director, Stephen Baghdadi, commented:
“The acquisition of the drill rig makes strong commercial sense given the expected scale of drilling over
the coming years.
“Securing another owner-operated, track-mounted rig provides greater flexibility to drill a wider range of
targets, particularly in areas where conventional truck-mounted rigs cannot access.
“In addition, our Company owned third rig is also being deployed to support additional drilling aimed at
expanding what we believe has the potential to evolve into an underground gold mineral resource after
open pit mining is completed.
“With multiple rigs operating, we expect a meaningful increase in both REE and gold-related news-flow
over the coming period.”
