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 Mba?ki 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.
