Orpheus Uranium Expands Marree Project with 2,513 km² Acquisition

Strategic Expansion of Uranium Footprint in South Australia

Orpheus Uranium Limited (ASX:ORP) has taken a decisive step to cement its position in one of Australia’s most prospective uranium provinces by agreeing to acquire seven exploration licences from Adavale Resources Limited (ASX:ADD). This deal, subject to customary conditions, will add approximately 2,513 square kilometres to Orpheus’ existing Marree Uranium Project tenure along the western margin of the Northern Flinders Ranges.

The acquisition not only significantly enlarges Orpheus’ landholding but also positions the company as the sole ASX-listed junior uranium explorer with district-scale tenure in a region otherwise dominated by established private and global players such as Heathgate Resources and Orano Mining Australia.

Historical Data Highlights Uranium Potential

The newly acquired licences come with a substantial historical exploration pedigree. Past drilling campaigns, notably by Cauldron Energy between 2008 and 2011, identified 36 drillholes with uranium equivalent grades exceeding 100 ppm eU₃O₈, with peak values surpassing 450 ppm. These results, primarily from the eastern portion of EL6553 encompassing the MacDonnell Creek and George Creek prospects, underscore the uranium fertility of the region.

George Creek, in particular, emerges as a near-term high-priority target due to its interpreted deepening sedimentary setting and redox transitions indicative of roll-front uranium mineralisation. The presence of palaeochannel-hosted sedimentary sequences, coupled with oxidised-to-reduced redox boundaries and elevated gamma responses, provides a compelling exploration model for the broader tenure package.

Native Title Agreements and Exploration Pathway

Crucially, the transaction includes existing Native Title Mining Agreements (NTMAs) with the Adnyamathanha Traditional Lands Association and The Dieri Aboriginal Corporation. These agreements offer a streamlined pathway for Orpheus to undertake future exploration activities, subject to appropriate consultations and regulatory approvals. The company also gains interim access rights to the acquired tenements pending final completion, enabling early-stage planning and preparatory work.

Transaction Structure and Funding

The consideration for the acquisition comprises an initial $50,000 non-refundable exclusivity payment, followed by two tranches each consisting of $300,000 cash and 2.5 million ORP shares subject to six-month escrow periods. The total cash outlay of $650,000 will be funded from Orpheus’ existing cash reserves, bolstered by prior asset sales.

Orpheus’ Managing Director Clinton Dubieniecki emphasised the strategic fit of the acquisition, noting it enhances the company’s uranium portfolio and provides opportunities to apply modern exploration techniques to unlock value from historical datasets.

Advancing Marree to Advanced Exploration Status

With the expanded tenure, the Marree Project graduates from greenfields to advanced exploration status within Orpheus’ project pipeline. The company plans to leverage existing datasets alongside new geophysical surveys and drilling campaigns to refine exploration targets. The focus will be on preserved Eyre Formation sediments beneath cover, aiming to delineate sediment-hosted roll-front uranium mineralisation.

This acquisition aligns with Orpheus’ broader strategy of consolidating high-quality uranium assets across Australia’s leading districts, positioning the company to capture value as exploration progresses in a jurisdiction with bipartisan support for uranium development.
