Updates also address Dateline's 100%-owned Argos Strontium Project in San Bernardino County and the Music Valley heavy rare earth project in Riverside County, California. Recurring disclosures include exploration programs, mineralized target areas, capital raises, strategic mineral exposure and corporate responses to matters affecting mining rights and project activity.
Dateline Resources (OTCQB:DTREF) appointed Vancouver-based GenCap Mining Advisory to lead financing for the Colosseum Gold Project in San Bernardino County, California. GenCap will manage the existing financing process and seek additional financiers.
According to Dateline, a recent Bankable Feasibility Study features accelerated mining of higher-grade ore, strong operating margins, and a short payback period, which the company expects will appeal to lenders and support a move into construction after financing.
Dateline Resources (OTCQB:DTREF) reported new drill results from the Colosseum Gold-REE Project in California, extending gold mineralization northeast of the North Pit and beyond the current Mineral Resource envelope.
Key intercepts include 287.3m @ 1.05g/t Au in CM25-41 and 214m @ 1.06g/t Au in CM26-42, both from surface, with higher-grade cores. Mineralization remains open at depth, supporting potential underground targets. Nearly 3,000m of REE-focused drilling is complete, the program is expanded to 18 holes, and specific gravity readings of 2.8–3.1g/cm³ align with gravity anomalies.
Dateline (OTCQB:DTREF) released a Bankable Feasibility Study for its 100%-owned Colosseum gold project in California, outlining strong economics from a technically simple open-pit restart.
At a US$4,200/oz base gold price, the project delivers US$785M pre-tax NPV5, 49.5% pre-tax IRR, 573koz production over 10.4 years, and US$1,825/oz AISC, with US$249M start-up capital plus US$25M contingency.
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.
