Colosseum Drilling Yields 64m @ 1.24g/t and 133m @ 0.95g/t Gold Intercepts
Dateline Resources reports robust gold intercepts from recent drilling at its Colosseum Gold-REE Project in California, exceeding current resource grades and supporting an updated mineral resource estimate and ongoing feasibility study.
- Broad gold intercepts exceed current Indicated resource grades
- 64m @ 1.24 g/t Au and 133m @ 0.95 g/t Au from recent drilling
- Mineralisation remains open at depth, supporting resource expansion
- Bankable Feasibility Study underway with strong project economics
- Rare earth element potential linked to nearby Mountain Pass geology
Strong Drilling Results Reinforce Resource Confidence
Dateline Resources Limited (ASX, DTR) has announced encouraging assay results from its ongoing drilling campaign at the 100%-owned Colosseum Gold and Rare Earth Element (REE) Project in California. Two recent reverse circulation drill holes beneath the North Pit have returned broad gold intercepts that surpass the grades of the current Indicated mineral resource blocks, signalling potential for an upgraded resource estimate scheduled for early 2026.
The standout results include a 64-metre intercept grading 1.24 grams per tonne gold starting from surface, featuring higher-grade zones up to 3.16 g/t Au, and an even broader 133-metre intercept at 0.95 g/t Au with localized grades exceeding 7 g/t Au. These findings confirm the continuity of mineralisation at depth and suggest the deposit’s scale and quality may be greater than previously modelled.
Advancing Towards Production with Bankable Feasibility Study
These drilling outcomes come as Dateline progresses its Bankable Feasibility Study (BFS), a critical step in de-risking the project and defining the path to production. The Colosseum Project already boasts a JORC-compliant resource of 27.1 million tonnes at 1.26 g/t gold, equating to approximately 1.1 million ounces of gold, with over two-thirds classified as Measured and Indicated categories. Previous economic assessments have highlighted a robust net present value of US$550 million and an internal rate of return of 61% based on a gold price of US$2,900 per ounce.
Drilling activities paused briefly for the Thanksgiving holiday in the US but are set to resume imminently, with further assay results expected to refine the resource model and support the BFS conclusions. The company remains confident that these developments will underpin a compelling investment case and operational plan.
Rare Earth Elements Potential Adds Strategic Value
Beyond gold, the Colosseum Project holds promising potential for rare earth elements, given its geological similarities to the nearby Mountain Pass mine, the largest rare earth operation in the United States. While the rare earths component remains under evaluation, Dateline has initiated planning for drill testing to assess this opportunity. This diversification could enhance the project’s strategic importance amid growing demand for critical minerals.
Additionally, Dateline’s portfolio includes the Argos Strontium Project, also in San Bernardino County, which is noted as the largest strontium deposit in the US, further broadening the company’s exposure to specialty minerals.
Looking Ahead
As Dateline Resources advances its drilling program and feasibility study, investors will be watching closely for the updated mineral resource estimate and rare earth assay results. These milestones will be pivotal in shaping the project’s valuation and development trajectory in a competitive mining landscape.
Bottom Line?
Dateline’s latest drilling success at Colosseum strengthens its resource base and sets the stage for a decisive feasibility study update.
Questions in the middle?
- How will the upcoming mineral resource update impact the project’s valuation?
- What are the prospects and timelines for confirming rare earth element resources at Colosseum?
- How might evolving market conditions and regulatory factors influence the project’s development?
