Lihir 4th quarter production higher

This was a result of higher mill and autoclave throughput, and improved recovery.

Newcrest Mining says in its December 2016 Report that this was partially offset by lower grade.

“Recovery was higher due to improved autoclave availability and utilisation following completion of the total plant shut in the September quarter, during which material bypassed the autoclave circuit and was fed directly into the NCA circuit to maximise throughput levels with consequential recovery losses.
