The United States Interior Department has reconfirmed ASX-listed Dateline Resources’ rights to mine and explore for gold and rare earths at its flagship Colosseum project in California. The long-awaited decision paves the way for a dual-commodity future for the company, just 10km from the US’s only operating REE mine, Mountain Pass.
The United States Department of Interior (DOI) has reconfirmed ASX-listed Dateline Resources’ rights to mine and explore for gold and rare earth elements (REE) at its flagship Colosseum project in California.
The decision, announced in the US yesterday, paves the way for a dual-commodity future for the company, just 10 kilometres from the US’s only operating REE mine, Mountain Pass.
DOI highlighted the strategic importance of the historic Colosseum mine as America’s second REE operation under a Trump administration executive order to bolster domestic mineral production.
Dateline’s ongoing right to mine is locked in under the California’s Mining and Desert Protection Acts. The Colosseum project, which is in and adjacent to national parks, now has a green light to extract gold and pursue REEs across the project’s claim boundary.
The confirmation came after a successful legal effort, let by the company’s US lawyer Kerry Shapiro, from Jeffer Mangels Butler & Mitchell, to resolve any DOI concerns over the validity of the company’s mining rights.
Colosseum has 1.1 million ounces of gold resources - with an impressive 67 per cent in the measured and indicated categories. The company now plans to weave REE exploration into its ongoing development story.
Dateline Resources managing director Stephen Baghdadi said: “The Department of the Interior’s public support and confirmation of our rights provide a strong foundation for moving the Colosseum project forward. We are pleased that the United States government continues to recognise the strategic importance of domestic mineral development.”
Sitting in San Bernardino County along the mineral-rich Walker Lane Trend, the Colosseum project has a rich past. Gold was first scratched out of the ground in the late 1800s, but it wasn’t until the 1980s that modern mining really kicked into gear. Canadian outfit LAC Minerals churned out 344,000 ounces from two open pits between 1989 and 1993 before low gold prices halted operation.
Gold giant Barrick scooped up the asset in 1994, holding it for nearly two decades with minimal activity, before eventually handing the keys to Dateline, which took over exploration in 2021.
Since then, the company has redefined the resource, pushing it to 1.1M ounces with staggering standout hits, such as 76.2 metres at 8.62 grams per tonne (g/t) gold and 100.6m at 4.16g/t.
The company recently wrapped up a compelling scoping study for its gold deposit, which proposed an 8.3-year mine life producing a considerable 75,000 ounces annually at an all-in sustaining cost of US$1490 (A$2490) per ounce. It will deliver a net present value of US$235M and a 31 per cent internal rate of return at a now very conservative US$2200 per ounce gold price.
With today’s gold price hovering around US$3000 per ounce - some US$800 higher - the project’s economics look immensely juicier, projecting total sales of US$1.344 billion over its life, with US$900M dropping to the bottom line as net revenue.
The Trump administration seems evidently more interested in the project’s REE potential, referring to the project in a press release as “America’s second rare earth elements mine”.
President Donald Trump’s executive order earlier this year aims to slash US reliance on China, which controls about 70 per cent of global REE supply, for the critical minerals that power everything from electric vehicles to defence tech.
Colosseum sits less than 10km north of the globally significant Mountain Pass mine. Geological studies and gravity surveys suggest Colosseum shares the same mineralising event and rock types as its famous neighbour.
For a company sporting a market cap well below $20M, Dateline is attracting the attention of government heavyweights. The gold numbers are enticing thanks to all-time high prices, but a government-supported REE kicker could be the kickstart Colosseum needs to turn the corner from explorer to developer.
