Angular and subangular crystals of sulphide have been found in the
pan concentrates and even in the fresh rocks.
Kyanite have been found also in the stream sediments, inferring a
metasediments units in the area.
Other sub rounded particular black minerals were found in the stream sediments : what are they ? not tourmaline, not magnetite, not rutile ! Are they the sources of the high contents of REE in the 1st phase of stream
sediments geochemistry ?
Future works on the stream sediments will include :
1) Full elements geochemical analysis of all stream sediments samples from the follow-up program
2) Petrography (ore microscopy) and Microchemical of gold grains
and various heavy minerals found in the stream sediments
