DiamondProspection Systematic prospection of great areas |
|
|
|
| « South-African » method.With this method, which is very much used, we do
not search the diamond itself, but heavy materials which accompany it and which are in
greater numbers. |
Littoral prospection.The coastal prospection
consists in searching the deposits which are at the edge of the littoral and on the beaches.The marine prospection is made by boats equipped with pumps in order
to sample the diamantiferous gravel. |

| Alluvial prospectionContrary to the
« South-African » method, the traditional alluvial prospection is characterized by the
direct search of diamond in the alluvial gravels. The major disadvantage of this
method is that it cannot be used in dry season, for a maximum of 5 months per year.
Indeed, it is necessary to sample the rivers by digging small wells, which are very
spaced at the beginning, then getting closer. |
Alluvial prospection in dense environmentWe could call this method the
« Belgian method ». We search for diamonds directly. It is very much
used in the Congo area, but the access to the deposits is made very difficult because
of the dense forests and the absence of dry season. It is used in Zaire, in Central
Africa and in Gabon. |
