Interim results from a recent field sampling program at Lincoln Minerals’ 100 per cent-owned Eridani uranium project have confirmed historic accounts of carnotite uranium mineralisation.
The sampling program was conducted as part of Lincoln’s uranium portfolio prospectivity review, which commenced in early 2024.
The sampling program was part of an initial assessment of the tenement to determine the attractiveness of the geological setting and to assess mineralisation potential in this known uranium region.
A recent review of historic data by Lincoln indicated accounts of carnotite uranium mineralisation at the abandoned Minbrie West talc and marble quarry, located on Exploration Licence 5851 (of which LML has 100 per cent ownership of all mineral rights excluding iron ore).
Lincoln took 12 outcrop samples from the quarry to confirm the historic carnotite mineralisation. The samples were then analysed using pXRF, which targeted the yellow mineralisation coating on the rock chips, now confirmed to be carnotite.
The Eridani uranium project focuses on the Minbrie West quarry, initially mined for marble and talc in 1919. The site was decommissioned following the discovery of carnotite, a secondary mineral usually formed from the weathering of uraninite.
The initial pXRF results will assist in future exploration, planned for 4Q CY24, including additional mapping and sampling along the identified fault zone. Subsequent phases of the investigation will involve re-assaying historic drill core, specifically Centrex Metals 2007-2011 drill holes located 2km SE of the project area, to further understand the extent and grade of the uranium mineralisation and to assist in target generation.
