Alligator Energy’s Samphire BFS: ISR design and hydrogeology notes for engineers
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Alligator Energy has started a bankable feasibility study (BFS) on its Samphire uranium project near Whyalla in South Australia, moving the in‑situ recovery (ISR) development closer to a final investment decision as uranium prices trade near 15‑year highs. The BFS will refine wellfield layouts, leach chemistry and processing flowsheets for the Blackbush and Plumbush deposits, building on previous ISR field trials and updated JORC resources. For geotechnical and hydrogeological teams, the work will focus on aquifer characterisation, permeability controls and containment of lixiviant within the target sandstone units.
Technical Brief
- Bankable feasibility scope includes detailed costing, mine scheduling and ISR wellfield development sequencing for Samphire.
- Hydrogeological characterisation will focus on transmissive sandstone units and any low‑permeability barriers controlling lixiviant migration.
- BFS outputs are intended to support project finance, including lender due diligence on ISR technical risks.
- Regulatory engagement in South Australia will centre on groundwater protection, baseline monitoring networks and ISR closure criteria.
- For geotechnical teams, wellfield layout refinement will drive requirements for access tracks, pad foundations and drilling platforms.
Our Take
Uranium pieces are a small subset of our 1017 Mining stories and 1898 tag-matched items, so Samphire’s move towards bankability in South Australia stands out against a coverage base still dominated by bulk commodities and gold.
South Australia features far less frequently than Western Australia and Queensland in our project coverage, which suggests Samphire could become one of the state’s more visible benchmark uranium developments for permitting and infrastructure expectations.
With no other uranium items currently linked in our database for Alligator Energy, advancing the Samphire uranium project appears strategically important for the company’s identity, concentrating technical and financing risk into a single Australian asset rather than a diversified project pipeline.
