Petra Diamonds revenue slips as China, Hong Kong demand wanes

So far, copper prices have failed to react significantly to news of supply disruptions, remaining more responsive to news from China, the world’s largest consumer.

The Vancouver-based miner has sold 30% of the company to La Mancha Holding in a deal that will grant it a majority stake in the massive Ity gold mine, in Côte d’Ivoire.

But the company is on track to reach its longer-term target of about 5 million carats of diamond production a year by 2019.

"Blue Moon" is expected to fetch up to $55 million when it goes under Sotheby's hammer on Nov. 11, in Geneva.

The move aims to reduce the gold producer's dependence on unreliable electricity supply from state-run utility Eskom Holdings.

Number five is a single pit that produces 77 million tonnes of iron ore per year.

The alleged deals involve Glencore's Collahausi mine in Chile, as well as Antamina and Antapaccay copper mines in Peru.

Under the agreement with AngloGold, Randgold will lead and fund a development plan to rebuild the Obuasi gold mine in Ghana.

Carroll, who led Anglo American from 2007 to 2013, will chair the company’s Vedanta Resources Holdings Ltd. unit and advise the group’s chairman.
