## 4 Research on the Effectiveness of Mineral Exploration
### Anomaly Characteristics of the Known Profile  
(1) The geo-electrochemical extraction anomalies of U, As, Th, and W exhibited a single-peak pattern, while the Pb and Mo anomalies displayed a rabbit-ear-shaped configuration, predominantly distributed between points 15 and 32, with a composite anomaly width of approximately 425 m. The peak concentration of U, the primary ore-forming element, reached 2.84 \(\times\) 10\({}^{-6}\), representing 6.8 times the background value, which provides a clear indicator for the lower segment of the KT4-11 uranium orebody at depths of \(-\)400 to \(-\)480 m. The associated element Mo showed an anomaly intensity ranging from 0.03 \(\times\) 10\({}^{-6}\) to 1.22 \(\times\) 10\({}^{-6}\), corresponding to 1.31-4.69 times the background value. Among all of the elements analyzed via geo-electrochemical extraction, Mo exhibited the strongest spatial correlation with the two underlying mineralized zones of the known orebody;  
(2) The soil ionic conductivity anomalies occurred between points 9 and 18, exhibiting a lambda-shaped morphology locally, with a peak value of 34.78 \(\upmu\)s/cm and a composite anomaly width of approximately 250 m. These anomalies correlate well with the upper segment of the KT4-11 uranium orebody and the industrial-grade tungsten ore body at depths of 0 to \(-\)160 m. While the soil thermally released mercury anomalies did not dis-play distinct peaks above the two uranium orebody segments, the general trend of the anomaly curve indicated elevated values relative to the background, forming an anomaly zone that is spatially consistent with the overlying mineralization;  
(3) Between the two orebody segments, the anomalous peaks of various elements were observed. It is inferred that mobile ions extracted through geo-electrochemical methods not only migrated vertically upward from the ore-hosting positions but also ascended along interlayer fractured zones to reach the surface. However, the known profile along Line L00 exhibited a negative topographic depression characterized by elevated peripheries and a depressed central area. Consequently, mineralization-related components may have been transported under the combined effects of rainwater runoff, chemical leaching, and gravitational forces, ultimately accumulating in the topographically low areas to form superimposed strong anomalies through enrichment processes;  
(4) At points 32-45, where engineering control was absent, the anomalies of elements such as U, Th, Mo, and Pb were observed, along with anomalies in soil ionic conductivity and thermally released soil mercury. Two possible reasons for these anomalies can be inferred: first, the upward migration of elements from the underground areas to the surface through fracture zones may have resulted in the formation of anomalies; second, there might have been undiscovered uranium ore bodies beneath these points [38].  
The results of the feasibility test indicate that the abnormal patterns and characteristics detected by the three methods effectively reflect the location of deep ore bodies. This demonstrates that geo-electrochemical integrated technology is both feasible and efficient for exploring concealed uranium deposits in this region [39].
