BHP Billiton says Olympic Dam repairs on track

SYDNEY, Nov 6 (Reuters) - Repair work to Australia's Olympic Dam uranium and copper mine is on track for a resumption of full production between January and March next year, mine owner BHP Billiton (BHP.AX) (BLT.L) said on Friday.

The company also reaffirmed its Oct. 21 statement that the mine was now running at 25 percent of ore-haulage capacity. A mechanical failure last month forced the mine to shut down its main haulage shaft and to switch to a smaller backup shaft. Olympic Dam is the world's fourth-largest copper deposit, the largest known uranium deposit and the fifth-largest gold deposit. (Reporting by Mark Bendeich; Editing by Jonathan Standing)
