Russia's second-largest gold producer Peter Hambro Mining Plc (POG.L) said on Tuesday it bought $40 million of its gold exchangeable bonds due 2012, leaving $53 million of the bonds outstanding.

The London-listed miner, which is a FTSE-250 share index constituent following its acquisition of cash rich iron ore producer Aricom Plc, purchased $87 million of its gold exchangeable bonds in February.

The firm had $180 million worth of the bonds with an initial redemption date in October, which had worried some investors about the firm's exposure amid the credit crisis. (Reporting by Julie Crust; Editing by Greg Mahlich)© Thomson Reuters 2009 All rights reserved
