Dateline’s Dual Gold-REE Ambitions Face Key Assay and Feasibility Milestones

Colosseum Project Momentum

Dateline Resources Limited (ASX – DTR) has delivered a comprehensive update on its 100%-owned Colosseum Gold-Rare Earth Elements (REE) Project in California, underscoring significant progress across exploration, feasibility, and corporate fronts. The company’s ongoing 10,000-metre drilling campaign is designed to underpin a Bankable Feasibility Study (BFS) targeting an average annual gold production of approximately 75,000 ounces over an initial 8.5-year mine life.

Recent geophysical surveys have identified six new gold breccia pipe targets, some comparable or larger than the existing 1.1 million ounce gold mineral resource, alongside three promising REE targets. These REE anomalies exhibit geophysical signatures akin to the nearby Mountain Pass mine, a world-class carbonatite-hosted rare earth deposit, suggesting compelling upside potential for dual-commodity development.

Feasibility Study and Operational Advances

The BFS remains on schedule, with GR Engineering Services appointed to manage the study. Key milestones include confirmation of mining contract pricing consistent with prior scoping assumptions, commencement of metallurgical testwork, and identification of long lead processing plant equipment. Infrastructure upgrades, such as the 10-kilometre access road, have been completed to support heavy haulage logistics.

Drilling activities are progressing with a combination of infill, extensional, and exploration holes, including sonic drilling to assess tailings storage facility integrity. The campaign is supported by a fleet of diamond and reverse circulation rigs, with over 1,400 samples dispatched for assay, ensuring a robust data set to inform mine design and resource updates.

Strategic Corporate Developments

On the corporate side, Dateline successfully completed a strongly supported A$25 million institutional placement, lifting cash reserves to over A$31 million and enabling accelerated development activities. The company also converted a significant number of options, further strengthening its balance sheet and repaying all outstanding debt.

Dateline secured 100% ownership of the Argos Strontium Project, a high-grade deposit located 100 kilometres from Colosseum, enhancing its portfolio of critical minerals. The Argos Project is notable for its historical celestite production and strategic importance given the U.S. reliance on imported strontium.

Further elevating its market profile, Dateline was added to the S&P/ASX All Ordinaries Index, reflecting its growing market capitalisation and investor interest. The company also initiated voluntary U.S. SEC reporting to align with the expectations of its substantial U.S. shareholder base, which now comprises approximately 37% of its register. Additionally, shares commenced trading on the Frankfurt Stock Exchange, broadening access to European investors.

Outlook and Next Steps

Looking ahead, Dateline plans to continue drilling through 2025 and into 2026, focusing on both gold and REE targets to unlock the full potential of the Colosseum system. The BFS is expected to complete early next year, paving the way for construction commencement. Concurrently, gravity data interpretation at Argos will inform forthcoming drilling campaigns aimed at defining a mineral resource estimate.

With strong government support underscoring the strategic importance of domestic critical mineral supply chains, Dateline is well positioned to advance its dual-commodity project in a jurisdiction favourable to mining development.
