Overview
Figure 1: Orpheus’ Marree Project and Native Title Determination Areas
Geology
The mineralisation model at the Marree project comprises both sediment-hosted and silcrete-hosted uranium mineralisation within Tertiary sediments, including the Eocene Eyre Formation and Miocene Namba Formation, both of which are known to host uranium mineralisation at the Honeymoon (Eyre Formation) and Beverley (Namba Formation) deposits.
Locally, at the nearby Jubilee prospect, uranium mineralisation is contained within silicified sandstone units of the Eyre Formation, at shallow depths within a paleochannel feature.
Exploration
Orpheus has compiled the historical datasets to derive mineralising models, and comprehend the exploration pathway for the tenure. These activities will define where future exploration activities are focused, establishing how the tenure fits within the current project pipeline and accompanying business strategy.
Orpheus has also worked closely with the local Native Title holders and other stakeholders to gain access to conduct exploration activities across the project area and lay the foundations for extending exploration programs beyond early-stage activities.
This includes:
- Executing an NTMA with The Dieri Aboriginal Corporation (TDAC), the Registered Native Title Body Corporate (RNTBC) for the Dieri Determination Area, which covers the northern areas of the Project.
- Executing an NTMA with the Adnyamathanha Traditional Lands Association (Aboriginal Corporation) Registered Native Title Body Corporate (ATLA), which covers the South-Eastern parts of the Maree Project.
These agreements allow Orpheus to pursue regulatory approvals and advance its mineral exploration programs to more advanced stages, including drilling, whilst respecting Native Title rights and cultural heritage.
