EL 6946 (Foelsche), annual report for the period 9-11-1991 to 8-11-1992

Abstract

The second phase of follow-up in the second year of tenure concentrated on the area of the one sample from the reconnaissance sampling programme which contained 28 chromite grains. 6 drainage samples and a 1 tonne bulk sample were collected in an attempt to pin down a source area for the chromites and to determine wether the source of the chromites contained diamonds. A re-appraisal of air-borne magnetic data covering this area was also completed but no significant anomalies were located. Sampling results indicate a source within the restricted catchment of a small gully. No diamonds were recovered from the bulk sample. Results from the follow-up geochemical sampling which took place during the first year of tenure have confirmed the original anomalous result and indicate gold/base metal mineralisation of limited extent in the dolomitic sediments of the Tawallah Group. Secondary copper mineralisation has also been noted in the McArthur Group sediments.
