BIDOU PROJECT : A MULTI-METAL DEPOSIT AT THE NW BORDER OF

CONGO CRATON IN CAMEROON

STREAM SEDIMENTS FOLLOW-UP

Proposed sampling points for stream sediments follow up

2

Stream sediment sampling points completed during the follow up

3

Sampling points which yield visible Gold grains in the pan concentrates

4

Sampling points which yield particular black minerals (?) in the pan concentrates

5

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
