2012 Minerals Yearbook CONGO (BRAZZAVILLE) U.S. Department of the Interior May 2015 U.S. Geological Survey THE MINERAL INDUSTRY OF CONGO (BRAZZAVILLE) By Philip M. Mobbs The economy of the Republic of the Congo, also known as of the Extractive Industries Transparency Initiative (Extractive Congo (Brazzaville), was based primarily on the production of Industries Transparency Initiative, 2012, p. 3). crude oil, which was estimated to account for about 65% of the nominal gross domestic product in 2012. Many of the oilfields Commodity Review were mature, but decreased production from the older fields was Metals expected to be offset in the short term by new offshore fields. International interest in the development of the nonfuel mineral Chromium, Copper, Gold, Lead, and Zinc.—Luyuan des resources of Congo (Brazzaville) has increased in recent years, Mines Congo evaluated the Moukassi prospect for chromite and much of the focus of multinational mining companies occurrences. The joint venture of MMG Exploration Holdings was on the country’s gold, iron ore, and potash resources Ltd. and Sanu Resources Ltd. explored the Kingouala and (International Monetary Fund, 2013, p. 19). the Reneville license areas for base-metal deposits.
