Adds details and background from paragraph 2 onwards

May 8 (Reuters) - Freeport-McMoRan FCX.N has pushed back restart of its flagship Grasberg copper mine in Indonesia by a year, and is now targeting a return to full production by early 2028, Bloomberg News reported on Thursday.

Reuters could not immediately verify the report.

Freeport-McMoRan did not immediately respond to a Reuters request for comment.

Grasberg operations were hit by a severe mudflow last September, after which CEO Tony Wenas said the mine was only expected to return to full production by 2027.

The delay is linked to changes Freeport is making to equipment used to load ore onto trains, the company said in April, after underground ore became wetter due to groundwater infiltration following the mine's shutdown in September.
