Abstract

This paper deals with an experimental programme carried out with a gold analyser in the period June to September 1979 at Loraine Gold Mines. Under reasonable assumptions, the use of the detector in the selective mining of low-grade narrow reefs such as the Basal Reef at Loraine Gold Mines, when compared with the conventional chip sampling method, can result in a saving of as high as R40 million over the life of a project. The difference could be even larger in a highly variable reef like the B Reef at the mine.
