Ivory Coast, the world's top cocoa producer, is seeking to diversify revenues by increasing gold output from 25 tonnes last year to 50 tonnes between 2020 and 2025, said Daniel Kablan Duncan at the opening of an ECOWAS meeting on mining and petroleum in the commercial capital Abidjan.

Mining sector turnover rose by 11.5 percent in 2017, an increase achieved mainly via exports of gold, manganese and nickel.
