Inductive Source Resisitivity (ISR)

Lamontagne Geophysics Ltd. is the only provider of Inductive Source Resistivity measurements. ISR has been shown to be sensitive to conductive and resistive alteration, and as such can be applied to exploration over mineral, geothermal or petroleum prospects where alteration is associated with emplacement processes. Mineralized targets include epigenetic and Carlin-type gold deposits, porphyries, roll front and Athabasca uranium, and VMS. Because ISR is sensitive to vertical resistivity contacts, it is effective in detecting dipping chromite, scheelite and silica mineralization, or salt diapirs and intrusions within sedimentary packages.
