| MWTP Supporting Document |

Author: OTML Date: September 2006 This document was prepared to support the State's granting approval of a Change Notice, to permit OTML to proceed with the Mine Waste and Tailings project (MWTP). It discusses the issue to be addressed (the fragile nature of the river system and the perceived increase in sulphur (up to 8%S) in tailings in the future), the likely riverine response and the proposal by which sulphur will be drastically decreased to <1%S. This document describes the flotation process, the pyrite concentrate (PCon) pipeline and the subaqueous storage of the PCon material. It also addresses rehabilitation of the Bige site. (Note that, due to size limitations, drawings and appendices have not been included in this posting.)
