Electrical and electromagnetic exploration of sulfide ore deposit in Ishiagu, Ebonyi state, Nigeria


Chinenye Edeani, Chukwudi. C. Ezeh and Ejiofor Ezike

Spontaneous Potential (SP) and Electromagnetic (EM) methods have been used to delineate and evaluate the sulfide ore bodies in Ishiagu area, Ebonyi State, Nigeria. The study area lies between latitude 0505613011N to 0505714511N and Longitude 0703010011E to 0703110011E, and covers an area of 5078527.16m2. The ABEM terrameter SAS 300 and ABEM WADI, VLF type 9133001869 were used to measure the S.P and the E.M. respectively. The results were plotted using excel 2007, Karous-Hjelt and fraser software. The points of negative anomaly in S.P were correlated with that of E.M points. The results show that the most promising sites for exploitation are located within the area underlain by the Asu-River group where the estimated overburden thickness from S.P anomaly averages 69m thick.
