GEOLOGICAL SURVEY OF DIAMOND
The diamond mining industry is one of the mainstays of Sierra Leone’s
economy. In 1968 diamonds accounted for 62% of the total value of exports. For
1969 the percentage will probably be higher, judging from the monthly purchases by
the Government diamond Office which buys nearly all of the diamonds produced
under the Alluvial diamond Mining Scheme.

Because of the prominence of diamond mining in Sierra Leone, this Bulletin,
which represents the outcome of seven years extensive fieldwork by the author, is of
major importance. In it Mr. Hall gives a comprehensive review of the history of
diamond mining in Sierra Leone and also of mining practice, in addition to a detail
account of the geology and geomorphology of the diamond fields.
