Geophysical Imaging of a "Blind" Zn-Pb-Ag Deposit

Properly constraining the shape and size of an ore body requires a comprehensive database of petrophysical, geophysical and geological information derived from both surface and borehole data. An integrated borehole and surface dc resistivity study enabled us to detect and delineate shallow Zn-Pb-Ag mineralization beneath thick overburden at the Nash Creek exploration area, New Brunswick, Canada. The 2D and 3D conductivity models are supported by downhole resistivity data and geochemical assay data from exploration boreholes.
