Hellyer Stringer Zone Project. Progress report No. 2 (CODES publication 21)

Abstract

INTRODUCTION The aim of the Hellyer Stringer Zone Project is to investigate the geology and geochemistry of the footwall stringer zone and associated alteration envelope, with the purpose of defining the physical and chemical processes involved in the formation of this zone, and their relation to the genesis of the overlying massive sulphide body. This report summarises the information obtained from January to June, 1989 and reports the results of the field work and analytical investigations concentrating on the distribution and mineralogical and geochemical characteristics of the alteration zone, as well as sulphur isotopic analyses of sulphide minerals within the stringer zone and stringer envelope zone. Dr. J. Bruce Gernmell spent 5 weeks at the Hellyer mine during the second quarter of the project and continued to log core of stringer zone, map underground development through the stringer zone, and collected samples for alteration and sulphur isotope studies.
