Chile’s worst civil unrest in decades means the Democratic Republic of Congo is a more attractive proposition for mining investment, according to billionaire Robert Friedland. While Chile, the world’s top copper producer, seeks measures to quell the social unrest that exploded last month, the election of President Felix Tshisekedi earlier this year has improved the prospects in Congo, Friedland said at the Mines and Money conference in London on Monday. Ivanhoe Mines, founded by Friedland, is developing the world’s second-largest copper-mining project in Congo, with production due to start in 2021.
