PERTH, March 7 (Reuters) - Fortescue Metals Group has trimmed its March quarter production guidance to a range of 8.5-9.0 million tonnes, down 0.5 million tonnes, after heavy rains hit its mining operations in the Pilbara area of Western Australia.
The company said in a statement it was working to maximise production throughout the rest of the quarter.
Rio Tinto , which also mines iron ore in the region, said its operations had been impacted by adverse weather conditions during the first quarter, but that it will announce any impact in its quarterly production report.
Earlier this month, Rio said its coastal operations had been hampered by cyclone-related weather, resulting in a likely impact to shipped tonnage for the first quarter.
"The weather conditions are certainly better now than they were two weeks ago," Rio Tinto spokesman Gervase Greene said on Monday.
"That said, obviously there was a fair bit of ground to catch up," he said.
A spokeswoman for BHP Billiton said the company had not put out any new guidance on its iron ore operations. (Reporting by Rebekah Kebede and Ed Davies in Sydney,sourced:Reuters)
