AR3 Commences 5,000m Drilling Program Targeting Uranium at Overland Project

Exploration Momentum Builds at Overland Uranium Project

Australian Rare Earths Limited (ASX: AR3) has officially kicked off its 2025 drilling program at the Overland Uranium Project in South Australia, marking a pivotal step in advancing this frontier uranium exploration play. The campaign, which commenced in late January, plans for approximately 5,000 metres of drilling through to the end of March, with the company committed to providing regular updates to shareholders.

The initial focus is on detailed mapping of a newly defined palaeovalley within Exploration Licence EL7001. This palaeovalley, identified during the 2024 program, hosts thick sequences of Murray group stratigraphy interspersed with sands, clays, and abundant lignite horizons, geological features that are considered key indicators for sedimentary-hosted uranium deposits.

Targeting High-Priority Zones with Proven Potential

Following the palaeovalley mapping, drilling will concentrate on the western margin where previous exploration intersected multiple lignite horizons accompanied by anomalous downhole natural gamma readings. These anomalies suggest significant uranium mineralisation potential, elevating the prospect from greenfields to a compelling exploration opportunity.

Complementing this, Australian Rare Earths has secured ministerial consent to acquire a 100% interest in the sedimentary-hosted uranium rights of EL6678 through the Sheer Gold Farm-In agreement. This approval unlocks an additional ~1,000 square kilometres of prospective tenure, with drilling slated to commence imminently on three high-priority target areas within this licence.

Awaiting Assay Results to Validate Exploration Model

Crucially, assay results from the 2024 drilling program are expected imminently. The company anticipates these results will provide valuable correlation with initial gamma and portable XRF data, offering greater confidence in the geological model and guiding subsequent exploration phases. These next steps may include further drilling and geophysical surveys planned for the June quarter.

Australian Rare Earths’ Managing Director and CEO, Travis Beinke, emphasised the significance of the current drilling campaign: "It's great to be out in the field and commencing our 2025 drilling program at the Overland Uranium Project, kicking off what will be an active year of drilling in a frontier uranium exploration play. Starting with drilling on western margins palaeovalley and its high-priority targets, we plan to have the rig turning on multiple targets across this highly prospective project area in the coming months."

Strategic Positioning in the Energy Transition Metals Sector

Australian Rare Earths is positioning itself as a key player in the energy transition metals sector, with its flagship Koppamurra Project focused on rare earth elements critical for electric vehicles and renewable energy technologies. The Overland Uranium Project complements this strategy by targeting uranium, a metal gaining renewed interest amid global shifts toward low-carbon energy sources.

With regulatory approvals in place and a robust drilling program underway, AR3 is advancing its exploration footprint in South Australia’s uranium-rich geological provinces. The coming months will be critical as assay results and drilling outcomes shape the project's trajectory and potential resource definition.
