Application of Boreholes Redox Mapping Technique for Sandstone-Type Uranium Exploration in Arlit, Niger

Exploration is a key fundamental step in the process of any uranium mining activity. Moreover, new deposit has been discovered context mine development. The objective present research studies to apply borehole redox mapping technique as guide for exploration sedimentary environment. Tarat formation study area Arlit divided into four units (U4, U3, U2, and U1) such Unit4 (U4) consists reduced gray fine consolidated sandstone alternating clay-silt; Unit 3 (U3) composed coarse medium with increasing presence micro-conglomerate towards bottom; 2 (U2) characterized by kaolinitic cement 1 (U1) sandstone. results oxyhydroxides distribution maps show high radiometric accumulation low zones (U3), while less zones. Therefore, generalized oxyhydroxide whole Formation that moderate fewer oxidation are suitable mineralization. In contrast, intense poorly mineralized.
