Dateline Resources (OTCQB:DTREF) commented on media coverage dated April 16, 2026 about legal proceedings in the United States related to the Colosseum Gold and Rare Earths Project.
The proceedings were commenced by the National Parks Conservation Association and name U.S. federal agencies; the Company was not named. According to the company, reporting omitted historical context about valid existing rights. Dateline says permitted activities at Colosseum continue under its Plan of Operations and it will monitor developments and inform shareholders of material updates.
Dateline Resources (OTCQB:DTREF ASX:DTR) completed an A$50.0 million institutional placement at A$0.40 per share, issuing 125,000,000 new shares and increasing cash to approximately A$96 million.
Funds will accelerate enabling works at the Colosseum project, support procurement, final optimization, exploration and provide equity for a future project finance facility; BFS due April 2026.
Dateline Resources (OTCQB:DTREF) has acquired and mobilised a second diamond drill rig to Colosseum to fast-track a planned 12-hole rare earth element (REE) program. The track-mounted rig can drill to 3,900 feet and will operate alongside a contracted rig to accelerate regional gold and REE testing.
Dateline also plans to deploy the rig to Music Valley and Argos as needed, while a company-owned third rig will support additional drilling aimed at expanding potential underground gold resources.
Dateline Resources (OTCQB:DTREF) completed a 2,172 line-kilometre helicopter-borne magnetic and radiometric survey over the expanded Music Valley HREE Project (20,520 acres) on 50m line spacings at 30m height.
Survey data has been sent to Mitre Geophysics for processing; field mapping and rock chip sampling are underway, with assay results expected in 5–7 weeks. The company noted 252 of 969 claims are subject to Federal Court proceedings.
Dateline Resources (OTCQB:DTREF) commenced exploration at the newly acquired Music Valley HREE Project in Riverside County, California on March 3, 2026. A 2,172 line-kilometre helicopter-borne magnetic and radiometric survey will start next week, flown at 30m height with 50m line spacing and expected to take 8–10 days.
REE specialist Tony Mariano Jr and structural geologist Dr Russell Mason will begin mapping and rock-chip sampling to target Pinto Gneiss outcrops and prioritize follow-up sampling.
Dateline Resources (OTCQB:DTREF) acquired the Music Valley HREE Project in Riverside County, California: 57 claims totaling 1,140 acres with historical USGS rock-chip results showing 6.69%–15.04% TREO and elevated yttrium, dysprosium and other HREEs.
Dateline also completed a US$1.0M strategic equity investment in Fermi Critical Minerals, gaining 4 million shares (of ~45 million) and exposure to eight U.S. projects; planned work will include mapping, confirmatory sampling, geophysics and target definition funded from cash of >US$53M.
Dateline Resources (OTCQB:DTREF) reports integrated high-resolution geophysics, geochemistry and drilling at the Colosseum Project that identify three carbonatite-style REE targets. Drill hole RC25-038 intersected mantle-derived rare earth elements at ~40 meters with elevated Ba, Sr, Ca, P, Th and U. A 12-hole diamond program is approved to test Target 1 (Clark Mountain Fault, ~1.2km by 150–200m) and Target 2 (Eastern Gravity High), with several holes planned beyond 750 meters.
The combined gravity, magnetics, radiometrics, IP and MT datasets, plus surface chemistry, increase confidence in a preserved, subsurface carbonatite system and refine drill locations.
Dateline Resources (OTCQB:DTREF) reported diamond hole CM25-41 at Colosseum returned 149.65 m @ 1.39 g/t Au from surface, including 55.2 m @ 2.83 g/t Au. The hole ended in mineralisation, confirming the North Pipe northeast extension remains open at depth.
The project hosts a JORC 2012 resource of 27.1 Mt @ 1.26 g/t Au (1.1 Moz); a May 2025 scoping study modelled an ~8.5-year open-pit with a 61% IRR at US$2,900/oz.
Dateline Resources (OTCQB:DTREF) completed infill gravity, magnetic and radiometric surveys at its 100%‑owned Colosseum Gold and Rare Earth Project, following an IP survey in Dec 2025. The datasets (543 gravity stations; 8.6 km² magnetic/radiometrics) are being integrated to refine targets before diamond drilling scheduled to start next week.
The integrated interpretation aims to finalise priority targets at depths of approximately 500–1,000 metres, with Mitre Geophysics assisting data integration and drill planning ongoing.
Dateline Resources (OTCQB:DTREF) completed a five-line ground induced polarization (IP) survey at its 100%‑owned Colosseum Gold and Rare Earth Project, California, during the December quarter. The IP program used a pole‑dipole array with 100 m dipole spacing, totaling ~13 line‑kilometres, and identified elevated chargeability zones at shallow and deeper levels. Preliminary IP anomalies are spatially coincident with magnetotelluric (MT) conductivity highs, a USGS radiometric thorium trend and a mapped northwest fault zone, prompting prioritization of drill targets where datasets converge. Mitre Geophysics is performing detailed inversion and interpretation; infill gravity and aeromagnetic surveys have been commissioned to refine targeting ahead of an expanded, deeper drilling program.
