Introduction 1.1 Background The Proponent, Newmont Boddington Gold Pty Ltd (NBGPL) proposes to extend the life of the existing Newmont Boddington Goldmine (NBG). NBG is located in the Shire of Boddington, approximately 12 km northwest of the town of Boddington and 120 km southeast of Perth, Western Australia. The mine is situated in the Darling Range, within the catchment of Thirty Four Mile Brook (Figure 1). The gold and copper mining operations at Boddington first commenced operations in 1987, with mining of the shallower oxide material. The operations entered care and maintenance in 2001. Following a feasibility study, mining operations recommenced in 2006, involving the basement ore-mining phase, with an anticipated 15 – 20 year mine life.
