Abstract

During the period 1982-1987 604 stream sediment samples were collected and investigated for scheelite and the concentrates the heavy mineral concentrates analysed for various elements.

The regional sediment sampling programme has shown that scheelite occurs in most of the supracrustal rocks which appear as enclaves in gneisses over an area of about 40,000 km².

Follow-up by ultra-violet light has revealed that scheelite occurs as stratabound mineralisation in banded amphibolite, in skarn horizons and in tourmalinite. The scheelite mineralised horizons are up to 4 m wide and can be traced with intervals for up to 3 km along strike.

Some of the heavy mineral concentrates have been analysed for gold and some anomalies have emerged. It is determined that gold and tungsten are closelycorrelated.
