Abstract: Nigeria is rich in mineral resources. In the past mineral exploration is mainly focused on oil and gas, Au and Tin and now exploitation of Li has been the hot point. Based on geological survey in a Li deposit in Nasarawa area IP ladder survey and audio magnetotelluric sounding survey are used to conduct profile test and prove the validity on the known ore body. Result of the test shows that the two geophysical techniques are effective to locate Li-bearing pegmatite. Combined with geological data the geophysical data can be used to optimally lineate target in the deposit.
