$35M Placement Positions Dateline for Colosseum Development

Highlights

• $35 million Institutional Placement Completed : Dateline has successfully secured $35 million through a strongly supported placement at $0.31 per share.

• Cash Reserves Strengthened: Following the placement, the Company’s total cash position has increased to over $58 million.

• IP Results Identify Coincident Anomalies: Coincident IP, conductivity and radiometric anomalies indicate deep sulphide targets - to be assessed with an imminent diamond drill campaign.

• Transition to U.S. reporting standards: To broaden its investor base and improve accessibility to U.S. investors, the Company is transitioning to U.S. reporting standards and related regulatory frameworks.

Dateline Resources Limited ( Dateline or the Company ) (ASX: DTR; OTCQB: DTREF, FSE: YE1) is pleased to announce that it has completed a $35 million placement which has increased the Company’s total available cash to over $58 million. The issue was well supported by new and existing institutional investors and was conducted at an issue price of $0.31 per share, resulting in the issuance of 112.9 million new Ordinary shares equating to 3.1% of the Company’s share capital ( Placement ). Shaw and Partners Limited acted as Sole Lead Manager and Bookrunner to the Placement. Dateline is now in its strongest financial position since acquiring the Colosseum Project.

Senior management and directors participated in the Placement with a total commitment of $1.35 million, including from the Company’s two recently appointed directors (subject to shareholder approval), further aligning management with shareholder outcomes.

The Company will use the funds to advance multiple parallel workstreams, including completion of the Bankable Feasibility Study, increased exploration capacity, expanded site works and the ordering of long-lead items required for the Colosseum mine restart.

Dateline’s Managing Director, Stephen Baghdadi, commented:

“ This capital enables us to act decisively in advancing development, expanding drilling, and testing deeper targets, while progressing a potential U.S. listing strategy. Our focus remains squarely on execution and value creation for shareholders. ”

Dateline now has converging technical datasets, together with the financial capacity, to pursue deeper REE and gold drilling. Two diamond drill rigs are mobilising to site, and Dateline is in the process of securing additional rigs, allowing for an accelerated and deeper drilling program.

About Dateline Resources Limited

Dateline Resources Limited (ASX: DTR, OTCQB: DTREF, FSE: YE1) is an Australian company focused on mining and exploration in North America. The Company owns 100% of the Colosseum Gold-REE Project in California.

The Colosseum Gold Mine is located in the Walker Lane Trend in East San Bernardino County, California. On 6 June 2024, the Company announced to the ASX that the Colosseum Gold mine has a JORC-2012 compliant Mineral Resource estimate of 27.1Mt @ 1.26g/t Au for 1.1Moz. Of the total Mineral Resource, 455koz @ 1.47/t Au (41%) are classified as Measured, 281koz @1.21g/t Au (26%) as Indicated and 364koz @ 1.10g/t Au (33%) as Inferred.

On 23 May 2025, Dateline announced that updated economics for the Colosseum Gold Project generated an NPV6.5 of US$550 million and an IRR of 61% using a gold price of US$2,900/oz.

The Colosseum is located less than 10km north of the Mountain Rare Earth mine. Planning has commenced on drill testing the REE potential at Colosseum.

Dateline owns 100% of the high-grade Argos Strontium Project, also located in San Bernardino County, California. Argos is reportedly the largest strontium deposit in the U.S. with previous celestite production grading 95%+ SrSO4.

	Criteria JORC Code explanation Commentary
	Drill hole Information • A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: o easting and northing of the drill hole collar o elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o hole length. • If the exclusion of this information is justified on the basis that the information is not Material, and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. • No drill hole information involved with the IP survey. • No information or results have been excluded from the attached table.
	Data aggregation methods • In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high-grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated. • No drill hole intercepts or weighting involved with the IP survey.
	Relationship between mineralisation widths and intercept lengths • These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). • IP survey lines laid out East-West according to industry standard practice and site specific details for Colosseum Mine by KLM Geophysics in Reno, NV.

	Criteria JORC Code explanation Commentary
	Diagrams • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. • Supporting figures have been included within the body of this release.
	Balanced reporting • Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced avoiding misleading reporting of Exploration Results. • No grades reported within this release.
	Other substantive exploration data • Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. • Multi-element analysis is being completed on 3 of the drillholes within the program. Waiting on results for analysis and interpretation. • Geotechnical & rock characteristics/structures were analysed in 4 of the core holes. • Geotechnical mapping was completed in both North and South Pits. • Downhole televiewer has been conducted on 3 diamond drilling core holes. • Groundwater level is being tested in every hole that intersects water, packer testing on some of the drillholes is also being evaluated. • IP geophysics was conducted over the claim boundary. Results are still being interpreted.
	Further work • The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. • At Colosseum, future work will include expanded drilling outside the North and South pits, deeper drilling in the North Pit, sampling of open pit benches, geological mapping, and further geophysical testing methods and analysis.
