ABSTRACT
The Uranium
exploration history of the Central African Republic (CAR) extends on two
periods separated by the independence in 1960, of the ex-Ubangi-Chari, a colony
of French Equatorial Africa. The uranium research is contemporary of the
French Atomic Energy Commission (CEA) implementation in this country in 1947
and done by the CEA. There began the first period. The second period started
after the 1960 year. Before the independence, the exploration works
were realized in two stages from 1947 to 1957 and from 1958 to 1961. The first
stage regarded the recognizing of uranium occurrences in the magmatic and
pegmatitic formations. For this, three missions were organized in the east of
the CAR. The first mission took place from March to July 1947. The second mission was realized from April to
June 1949, and the third mission from November to April 1956. The second stage had concerned the uranium
research in sedimentary basins by the prospecting Mbaïki Series (January
1958-January 1960) and Fouroumbala Series
(August 1959-June 1961). These series offered the chance to CEA to discover the
Bakouma uranium deposits. After this discovery in 1965, the falls of prices of
the uranium provoked altered stoppings and resumptions of
works with the following societies: the Company of uranium ores of Bakouma
(URBA) 1969; Centralafrican uranium (URCA) in 1975 but dissolved in 1981; in 1989-1991, the Japanese Nuclear Power Corporation (PNC) for a deposit
re-examination; URAMIN Centrafrique in 2004-2005 and AREVA Resources Centrafrique
in 2007. The last-mentioned had stopped works since 2012.
