Star Metro - Dateline Delivers Further High-Grade Intercepts from North Pipe at Colosseum

Of note, RC25-002 and RC25-006 were drilled on the south-east side of the North Pit mineral resource, not far from RC25-001 and RC25-004 that were recently reported (see Figures 1 and 2). This area demonstrates a broad zone of mineralisation with grades comparable with the existing mineral resource but contains a high-grade core (RC25-002 - 10.67m @ 7.27g/t Au, RC25-006 - 13.72m @ 4.48g/t Au) with grades that are significantly higher than the mineral resource.

Highlights

• High-grade gold intercepts further strengthen the mineralisation model in the North Pipe:

  • RC25-002 returned 62.48m @ 2.52 g/t Au from 25.91m

    • Incl. 10.67m @ 7.27g/t Au from 39.62m

  • RC25-006 returned 108.20m @ 1.18 g/t Au from 9.14m

    • Incl. 13.72m @ 4.48g/t Au from 56.39m

  • RC25-020 returned 117.34m @ 1.01 g/t Au from 0m

    • Incl. 9.14m @ 1.84g/t Au from 36.57m

Commenting on the new results, Dateline's Managing Director, Stephen Baghdadi, commented:

"These newly reported results come from an area that was sparsely populated in the previous mineral resource model. The overall mineralised envelope and grade matches what we anticipated in this area and the high-grade core has delivered excellent grades and widths.

"The North Pit is currently scheduled to be the first area to be mined in the schedule and the addition of high-grade ounces could improve the mine production in the early years of the project."

Following the Thanksgiving break, drilling has resumed with one rig before the scheduled Christmas-New Years break.

Assay results will continue to be released as they are received and analysed.

Dateline Resources Limited (ASX:DTR)(OTCQB:DTREF)(FSE:YE1.F) 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 Pass Rare Earth mine. Planning has commenced on drill testing the REE potential at Colosseum.

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