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) 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.
Dateline Resources (OTCQB:DTREF) completed a $35.0M institutional placement at $0.31 per share, issuing 112.9M new ordinary shares and increasing cash to over $58M as of January 23, 2026.
Proceeds will fund an accelerated Colosseum development program including deeper REE and gold drilling (two diamond rigs mobilizing), completion of a Bankable Feasibility Study, expanded site works, and ordering long‑lead items. Senior management and directors committed $1.35M to the placement (director allocations subject to shareholder approval). The company is progressing a transition to U.S. reporting standards and has appointed K&L Gates to advise on legal matters.
Dateline Resources (OTCQB:DTREF) reports the Colosseum Bankable Feasibility Study (BFS) is in final stages with major workstreams advanced. Metallurgical test-work confirms 91–92% gold recovery at 106µm grind, matching prior Scoping Study assumptions. Geotechnical studies support improved open pit design and a potentially reduced strip ratio. Historic concrete processing foundations were uncovered, which may cut construction time and capital. The project will adopt a closed-loop dry-stack tailings approach with a prioritized filter plant (long-lead). Key long-lead equipment orders are being negotiated. The Company notes the gold price has risen from the May 2025 assumption of US$2,900/oz to >US$4,600/oz, expected to materially improve project economics. BFS completion will incorporate final engineering, scheduling and cost estimates.
Dateline Resources (OTCQB:DTREF) reported drilling results at its 100%‑owned Colosseum gold and rare earth project, San Bernardino County, California. Multiple RC and diamond holes returned wide, near‑surface gold intercepts, including 295.64m @ 1.04 g/t Au and 300.21m @ 0.66 g/t Au. Intercepts extend beyond the current mineral resource envelope and the felsite breccia pipe remains open to the northeast and at depth. MT conductivity data aligns with new intercepts, supporting targeting. RC holes reached ~300m depth (practical RC limit); diamond core drilling will test deeper continuity.
Dateline Resources (OTCQB:DTREF) appointed George Brack and Phillips Baker Jr as Non-Executive Directors effective January 5, 2026, strengthening the company’s North American board presence.
Mr Brack brings over 30 years in mining finance and corporate development, including 16 years on the Wheaton Precious Metals board. Mr Baker served as CEO of Hecla Mining from 2001–2024 (23 years) and received the 2017 William Lawrence Saunders Gold Medal from AIME. The appointments are aligned with Dateline’s plan to advance the Colosseum Gold-REE Project and expand U.S. critical minerals activities, and are intended to support management as the project progresses toward feasibility and development.
Dateline Resources (OTCQB:DTREF) reported further high‑grade reverse circulation drilling results at its 100%‑owned Colosseum gold and REE project in San Bernardino County, California on December 15, 2025. New assays from 12 RC holes below the South and North Pits improve continuity and, in places, exceed the existing mineral resource grade.
Key assay highlights include RC25-002: 62.48m @ 2.52 g/t Au (incl. 10.67m @ 7.27 g/t), RC25-006: 108.20m @ 1.18 g/t Au (incl. 13.72m @ 4.48 g/t), and RC25-020: 117.34m @ 1.01 g/t Au. The North Pit remains planned as the first mining area; company commentary says added high‑grade ounces could improve early production.
Dateline Resources (OTCQB:DTREF / ASX:DTR) reported further reverse circulation drilling results at its 100% owned Colosseum Gold‑REE Project in San Bernardino County, California on December 3, 2025. Two holes beneath the North Pit returned intercepts that exceed the current Indicated block grades and are expected to improve nearby mineral resource grades in a new estimate planned for early 2026.
Key intercepts: RC25‑001: 64.0m @ 1.24 g/t Au from 0m (incl. 7.66m @ 3.16 g/t Au from 53.34m). RC25‑004: 132.58m @ 0.95 g/t Au from 3.05m (incl. 3.05m @ 7.09 g/t Au from 112.8m). Drilling paused for Thanksgiving and will resume shortly; a bankable feasibility study continues.
Dateline Resources (OTCQB:DTREF) updated on drilling at its 100%‑owned Colosseum Gold‑REE Project, California, dated October 27, 2025. Three rigs (one diamond, two RC) are active; a sonic rig completed tailings work and was demobilised. The compact BFS infill/extensional program is 67% complete (32 holes, 4,257 m) with an estimated finish of November 7, 2025. Approximately 1 Mt of historical stockpiles grading ~1 g/t Au (~30,000 oz) will be RC drilled to confirm inclusion in the mine plan. Sonic drilling confirmed the TSF foundation is suitable for future dry‑stack lifts. New high‑priority gold Targets 1, 5, 6 and REE Target 2200N are next.

Stockpile: ~1 Mt historical stockpile at ~1.0 g/t Au (~30,000 oz) will be RC drilled to confirm grade for inclusion in the mine plan. Tailings: sonic drilling confirmed foundation stability suitable for dry‑stack lifts. >1,400 samples are at the lab; follow‑up drilling will test high‑priority gold targets 1,5,6 and REE target 2200N.
Dateline Resources (OTCQB:DTREF) completed an independent 3D geophysical review of the Colosseum project on Oct 20, 2025, ranking six breccia-pipe gold targets to guide drilling.
All six targets show coincident gravity lows and low-resistivity signatures; Target 1 is top-ranked, Target 5 shows a conductive zone to ~900m with resistivity 500 Ω·m, and Target 6 has a 300m×300m "bullseye" with continuity to ~700m. The company plans phased drilling of highest-ranked gold and REE targets to target growth of the 1.1 Moz Colosseum resource.
