Extractive Industries

Oil and Gas

Congo-Brazzaville produced about 2.5% of Africa's total crude oil output p.a.  When taken alongside natural gas extraction, combined petroleum earnings have supplanted forestry as the mainstay of the economy, with the government's annual budget significantly part-funded through borrowing against future, expected, petroleum earnings.   Global price reductions from 2014/5, however, have reduced the amount of revenue accruing to the government, increasing strains on the national budget. 

Mining

Diamond, gold, base-metals and construction materials were produced in addition to hydrocarbons. Artisanal diamond production in 2014 was reported to be valued at c.$1.5m, a decease from a figure of c.$5.25m in 2008, the first year following Congo-Brazzaville’s re-admittance as a participant in the Kimberley Process in November 2007.

The country's undeveloped mineral resources include potash, lead, zinc, uranium, copper, phosphates, gold and magnesium.
