High-grade uranium mineralisation confirmed at Eridani

Lincoln Minerals has confirmed uranium mineralisation at its Eridani project located on the Eyre Peninsula in South Australia.

The company conducted a first-pass reconnaissance sampling program as part of its uranium prospect review, which identified high levels of carnotite uranium mineralisation through portable X-ray fluorescence (pXRF) analysis.

Notable pXRF results included hits of 9250 parts per million (ppm) uranium at MQ12, 6219ppm uranium at UMQ11 and 6890ppm uranium at UMQ10.

Eridani is located around an abandoned quarry shut down by the South Australian Government in 1944 due to high surface radioactivity.

“The alteration occurs along fault and shear zones 2km southeast of the quarry and is proximal to Hiltaba Suite granite intrusions,” Lincoln said.

“The drill holes, initially part of Centrex Metals’ 2007–11 iron ore exploration program, were not previously assayed for uranium; however, recent discoveries of uranium mineralisation by Alligator Energy, northeast of the Eridani project area, have prompted further investigation.”

Lincoln’s recent pXRF analysis support Centrex and Alligator’s findings, providing a foundation for further exploration efforts.

Samples have been submitted for laboratory analysis, with results expected in October 2024.

Lincoln aims to conduct additional exploration, including mapping, sampling, and geophysical data review to plan out potential drilling campaigns.

Succeeding phases of the exploration program will involve re-assaying historic drill core such as Centrex’s drill holes to further understand the extent and grade of the uranium mineralisation to assist with target generation.
