Petra Diamonds was always on the lookout for new mines, the London-listed producer said yesterday, as Anglo American, the owner of De Beers, holds a global review of its assets. “We are always aware of all other diamond mines in the world,” Petra chief executive Johan Dippenaar said. “We are always looking, but it will not distract our focus. We have an exciting growth profile.” Petra reported yesterday that full-year revenue grew 17 percent to $473 million (R5 billion) as it produced 3.1 million carats. – Bloomberg
