SYDNEY--Australia's Macmahon Holdings Ltd. (MAH.AU) said a unit of Glencore Xstrata PLC (GLEN.LN) had prematurely terminated a contract for mining services at the CSA copper mine in New South Wales.

The Perth-based contractor said it was seeking an explanation for the early termination.

The shaft-sinking project at the mine was expected to contribute about 6 million Australian dollars (US$5.8 million) to company revenue this month, and A$80 million over the upcoming fiscal year, Macmahon said.
