Report on EL 5046 Mt Osborne year ending 06-01-1988

Abstract

Exploration Licence 5046 is in the southeastern sector of a synclinorial region lying between major domes at Brocks Creek and Golden Dyke. It is underlain by greywackes and siltstones of the Burrell Creek Formation apart from a small area of Mt Bonnie Formation banded iron formation and black slate in an anticlinal core in the extreme southeast of the area. A gold exploration programme, carried out between July and December 1967, comprised geological reconnaissance and soil stream sediment and rock-chip geochemistry and was completed at a cost of $11,693. This work disclosed anomalous gold values associated with a zone of quartz-hematite mineralisation in Burrell Creek Formation in the southwest and with the banded iron formations in the southeast. Proposals are made for follow-up mapping and sampling at an estimated cost of $15,400.
