The above 1D model at 2.5 Hz shows the two very low resistivity areas at a depth of 300-500m (located by yellow circles). The black sands/gravels were encountered trenching at UTM 802000 which is the relationship we were seeking to correlate. The geophysics data was changed to 0 to 20 ohm-m, rather than 0 to 100, and was modified in order to better highlight zones of very low resistivity, and to better differentiate the resistivity within the 0 to 10 ohm-m range.
