1. Introduction
1.1 Background The Mount Morgan Mine (the Project) is owned and operated by Heritage Minerals Pty Ltd (herein referred to as the proponent). The Mount Morgan Mine is located near the town/location of Mount Morgan, 38 kilometres southwest of Rockhampton in Central Queensland. A site locality map is provided in Figure 1 . Mount Morgan Mine is bound to the north and west by undulating hills and largely bound to the east by the Dee River. The Mount Morgan Mine is the subject of 30 mining leases. Although Heritage Minerals Pty Ltd is the holder of the Mining Leases (MLs), the site is managed by the Department of Natural Resources and Mines, Manufacturing and Regional and Rural Development (DNRMMRRD) through the Abandoned Mines Lands Program (AMLP). No other tenements exist over the site. The mine has a long history, starting in 1882 as an open-cut gold mine, converting to an underground copper and gold mine, and then in 1935 transitioning back to open-cut and continued until the mine closed in 1980. Then from 1982 to 1991 it ran as a tailings treatment operation recovering gold. And now the current owners intend to reinstate it as a gold and copper project. The project will directly impact on 67 individuals of Grevillea hockingsii , which is listed as vulnerable under the Queensland Nature Conservation Act 1992 (NC Act). The proponent intends to mitigate unavoidable impacts to the species by growing seedlings and planting these at a nearby recipient site. The general area where the impacted G. hockingsii are located has been determined to be disturbed remnant and “in the wild” by the Author who is under the Queensland Nature Conservation Act 1992 (NC Act) as a Suitably Qualified Person (SQP) to make such determinations. Qualifications can be found in Appendix A .
Proposed development
1.2
The project will involve the excavation and treatment of historical Acid Rock Drainage (ARD) generating mine waste and redeposition of processed tailings into the Sandstone Gully Tailings Storage Facility (TSF), Open Cut Pit (OCP) and the Upper Mundic Gully Tailings Storage Facility (TSF). This will result in the removal of the source of ARD generating material from across the site reducing recharge of and seepage from mine waste structures. This will reduce impacts from the Mount Morgan Mine to the receiving environment including the Dee River in accordance with the State’s Rehabilitation Plan (Unger et al, 2003) and Phase 2 Agreement.
