A review of mise a la masse surveys at Elura

Abstract

Only limited mise à la masse (applied potential) surveys were conducted at Elura during exploration drilling because the holes usually collapsed immediately after casing removal. This prevented the implanting of mise à la masse current electrodes into the massive sulphide intersections and the logging of holes with electrical tools. A surface survey (Ogilvy, 1976) was conducted by the Bureau of Mineral Resources in 1974 using the sulphide intersection in DDHE2 to energise the orebody. Hole to hole measurements between energised intersections in DDHE2 and DDHE3 and potential measurement hole DDHE5 were also conducted by the Geological Survey of N.S.W. in 1974 (Tyne, 1975).
