Highlights
• Strong gold intercepts confirm the continuity of mineralisation at depth in the North Pipe:
o RC25-001 returned 64.0m @ 1.24 g/t Au from 0m (beneath the existing north pit)
• Incl. 1.52m @ 3.17g/t Au from 3.05m
• And 1.52m @ 5.68g/t Au from 30.48m
• And 7.66m @ 3.16g/t Au from 53.34m
o RC25-004 returned 132.58m @ 0.95 g/t Au from 3.05m
• Incl. 3.05m @ 3.25g/t Au from 27.43m
• Incl 3.05m @ 7.09g/t Au from 112.8m
Dateline Resources Limited (ASX: DTR, OTCQB: DTREF, FSE: YE1) (Dateline or the Company) is pleased to announce further drilling results at its 100%-owned Colosseum Gold and Rare Earth Element (REE) Project in San Bernardino County, California. The results from a further two reverse circulation (RC) holes drilled below the North Pit have provided gold assay results that exceed the mineral resource grade for the Indicated blocks that they intercepted, with the expectation that this result will improve the mineral resource grade for the blocks in the vicinity when a new mineral resource estimate is undertaken early in 2026.
RC25-001 returned a broad intercept of 64.0m @ 1.24g/t Au from surface, including a high-grade zone of 7.66m @ 3.16g/t Au from 53.34m.
RC25-004 had a broad intercept of 132.58m @ 0.95g/t Au from 3.05m. incl 3.05m @ 3.25g/t Au from 27.43m and 3.05m @ 7.09g/t Au from 112.8m).
Both of these holes have returned higher grades than currently estimated in the Indicated mineral resource blocks they intercepted.
Drilling was suspended for the Thanksgiving holiday in the United States and is planned to recommence in the coming days.
Dateline will continue to update shareholders as additional assay results are received and as the Bankable Feasibility Study progresses. The Company remains confident that the drilling program will confirm the feasibility of the Colosseum Gold-REE Project by better defining the mineral resource base and de-risking the path to production.

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.
