The ship, the seventh in De Beers' fleet, will increase annual output from the country by 35%, and will cost $468 million to build. AngloAmerican, the miner's parent company, will contribute $234 million, and theNamibian government - De Beers' 50:50 joint partner in the water-based venture -will fund the other half. "Some of the highest-quality diamonds in the world are foundat sea, off the Namibian coast," said De Beers CEO Bruce Cleaver. "With thisinvestment, we will be able to optimize new technology to find and recoverdiamonds more efficiently and meet growing consumer demand across the globe."
