GlencoreXstrata has announced it will close its Mount Margaret operations as it finishes work at its last remaining open pit, E1 North, in March. It started mining at the operations in July 2012, after it acquired the E1 and Monakoff copper tenements from Exco Resources. At the time Xstrata said production from these deposits would make an "incremental contribution" to Ernest Henry's production profile from the second half of 2012, and were designated as satellite operations to Ernest Henry.
