Abstract
Two dimensional geoelectric resistivity survey was conducted at the mining site in Pingel
village, MagamaGumau, Bauchi state, Nigeria. The survey was undertaken to characterize
the cassiterite bearing layer in the area. A test profile was conducted along a point with an
exposed subsurface that reveals different layers of the earth, including that rich in
cassiterite, to detect the best configuration to be used. Based on the result obtained from the
test profile, the Schlumberger array proved to be a better representation of the layering of
the study area. A total of five profiles were then taken and the result of the 2D resistivity
survey revealed the occurrence of three to four layers in the geoelectric models. The top
layer consists of earth materials with resistivity values mostly less than 120 Ωm, inferred to
consist of mainly clayey sand and laterite with an approximate thickness of 4.5 m. The
second layer has resistivity range of 60 Ωm to 250 Ωm and may consist of weathered and
fracture rocks with cassiterite composition at approximately 7.0 m depth. The third layer is
composed of highly resistive materials, generally greater than 800 Ωm, at a depth stretching
beyond 7 m. The high resistivity values could be associated with the fresh basement.
