Orpheus Uranium Secures 2,513km² Marree Expansion in Executed Sale Agreement
Orpheus Uranium has executed the Sale Agreement with Adavale Resources (ASX: ADD) to acquire up to seven exploration licences covering approximately 2,513 km² contiguous with its existing Marree Uranium Project tenure. The execution, announced 14 August 2026, follows the binding agreement entered 11 June 2026 and materially expands the Company’s footprint in a region known to host sedimentary-style uranium mineralisation.
What the acquisition means for the Marree Uranium Project
The acquisition consolidates prospective ground and strengthens Orpheus’ exploration portfolio in a region known to host sedimentary-style uranium mineralisation. Orpheus or a wholly owned subsidiary will assume operatorship of the tenements ahead of completion, enabling permitted exploration activities to advance the licences to a drill-ready position. This interim work is intended to allow drilling as soon as practicable following receipt of necessary approvals.
The Company continues to assess opportunities to both expand and rationalise tenure within the broader project area, targeting consolidation of the most prospective ground.

Understanding sedimentary-style uranium
Sedimentary-hosted uranium mineralisation refers to uranium concentrated within sedimentary basin rock layers. This style of deposit is often amenable to lower-cost extraction methods compared to hard-rock uranium deposits. The Marree region is known to host sedimentary-style uranium, making the expanded tenure prospective for this deposit type.
The licences are contiguous with Orpheus’ existing Marree Uranium Project tenure, and the Company is targeting consolidation of the most prospective ground.

Conditions precedent and next steps
The transaction is subject to conditions precedent before completion. The acquisition has not yet completed and remains conditional on regulatory and stakeholder approvals.
- Assignment of two Native Title Mining Agreements (“NTMAs”) relating to exploration activities.
- Completion of regulatory processes to transfer tenements to Orpheus or a wholly owned subsidiary.
- Interim operatorship and permitted exploration work to reach drill-ready status.
- Drilling to commence as soon as practicable following necessary approvals.
The Marree expansion forms part of a broader tenure-growth strategy. Orpheus recently extended into Western Australia via the Oobagooma Uranium Project, with the sale agreement executed and progressing to completion. The Company now holds tenure across South Australia, the Northern Territory, and Western Australia, all jurisdictions permitting uranium exploration and development.
According to the announcement, this acquisition will significantly expand the Company’s Marree Uranium Project and provide Orpheus with additional prospective tenure in a region known to host sedimentary-style uranium mineralisation.
