Abstract

In surface geophysical surveys, resistivity contrast between the ore and host rock plays a vital role in the success ratio of the surveys. To overcome the problem of insufficient resistivity contrast, a modified method, Mise-a-la-masse, as tried and found to be very effective in tracing the extensions of polymetallic sulphides intersected in a borehole. The method was applied to Pb-Zn and sulphide hosted gold prospects in Rajasthan and the results obtained indicate that Mise-a-la-masse method can be successfully employed for delineating subsurface extension of polymetallic sulphide deposits.
