Samphire uranium project: ISR field trials and 2030 schedule lens for engineers
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Alligator Energy is pushing its Samphire in-situ recovery uranium project near Whyalla towards a potential 2030 start, following a 67 per cent increase in mineral resources and ongoing infill and step-out drilling across the Blackbush and Plumbush deposits. The company is progressing a pre-feasibility study, hydrogeological testwork and leach trials to refine wellfield design, acid consumption and recovery factors, while advancing environmental and Native Title approvals. For engineers, the timetable hinges on ISR field trials confirming suitable sandstone permeability and groundwater behaviour in the Eyre Formation aquifer.
Technical Brief
- Environmental approvals will hinge on demonstrating ISR containment, aquifer restoration and minimal surface disturbance.
Our Take
The 67 per cent mineral resource increase at the Samphire uranium project materially strengthens the bankable feasibility study that Alligator Energy kicked off in early 2026, improving the likelihood of a robust reserve conversion ahead of the 2030 production target.
Our database shows several recent uranium items but only a handful tied to South Australian in-situ recovery projects, so Samphire’s ISR field-leach successes in 2026 position Alligator Energy as one of the more advanced ISR proponents in that jurisdiction.
The confirmation of ISR performance in the 2026 field trials near Whyalla reduces technical risk around groundwater behaviour and leach recovery, which is critical for securing financing and approvals on the timeline implied by the 2030 uranium production goal.
