Alligator Energy Limited, an Australian uranium exploration company, has recommenced its drilling program at the Big Lake Uranium Project in the Lake Eyre BasinSouth Australia. This resumption follows a hiatus caused by persistent rainfall after the initial discovery success in 2026.
The Big Lake Project is strategically located in the northern extensions of a proven uranium-bearing sedimentary system. This system hosts several significant uranium operations, including Beverley, Four Mile, and Honeymoon ISR uranium projects. The project shares key characteristics with world-class hydrocarbon-related ISR uranium districts, making it a promising area for exploration.
The 2026 Discovery at Site 10
In Alligator Energy’s frontier drilling at Site 10 yielded a significant exploration success. The drilling intersected substantial thicknesses of anomalous uranium mineralization within interbedded sand units of the Namba Formation. This discovery provided the first proof-of-concept for the presence of significant uranium mineralization within the Lake Eyre Basin sediments.
The discovery validated the company’s exploration model and highlighted the potential for the basin to host a new sedimentary uranium district. Andrea Marsland-Smith, Alligator’s CEO and Managing Director, emphasized the importance of this discovery, stating, “Our discovery at Site 10 in 2026 provided the first tangible evidence that the Lake Eyre Basin sediments can host uranium mineralization, validating a geological model that has the potential to unlock a completely new uranium district.”
Resuming Exploration in 2026
Following the 2026 discovery, persistent wet weather conditions limited the company’s ability to return to Site 10. However, with the resumption of exploration activities in 2026, Alligator Energy is now poised to follow up on this discovery and further assess its scale and potential. Marsland-Smith noted, “This upcoming program is particularly exciting as we now have the opportunity to follow up the discovery and further assess its scale and potential.”
The company is entering a highly active phase of exploration, with the upcoming drilling program representing an important step in assessing the scale and continuity of the Site 10 discovery. Additionally, the program will test a pipeline of prospective targets across EL 6367. Marsland-Smith added, “The success achieved by the team to date reinforces our view that Big Lake has the potential to become a strategically important uranium project within Alligator Energy’s growing portfolio of advanced uranium assets.”
Alligator Energy’s resumption of exploration activities at the Big Lake Uranium Project marks an exciting phase in the company’s quest to unlock the potential of the Lake Eyre Basin. With the promising discoveries made in 2026 and the resumption of exploration in 2026, the company is well-positioned to make significant strides in uranium exploration in South Australia.
