The Zeehan silver-lead-zinc field is in the West Coast Region of Tasmania. Following on the geophysical work carried out for Zeehan Explorations in 1947-1948, the Bureau was requested to carry out a survey on the Mariposa lease held by North Broken Hill Ltd. The purpose of the survey was to examine the Mariposa area for possible magnetic and gravity effects associated with the known mineralization and thence to determine the extent of this mineralization; and also to investigate the swamp covered limestone area for hidden mineralization. Further, it was considered that the results of the survey and behaviour of the instruments in the difficult terrain would serve as a guide to the usefulness of the magnetic and gravity methods in other similar prospecting areas in the Zeehan field. An account of the geophysical work and its results is given in this report.
