2.5.1. Previous Site Disturbance
Mount Morgan Mine has a long history spanning from the commencement of mining operations in 1882
and was the primary reason for the establishment of the adjacent Mount Morgan township. From 1882
to 1990, 133 Mt of waste rock and tailings were generated during the extraction of 250 t of gold and
360,000 t of copper (AARC, 2017). There have been various types of operations and mining lease
holders over this period which have resulted in impacts to environmental values at the site and receiving
environment including the Dee River. Overall, the disturbance on site is widespread and water sources
on site are contaminated primarily due to acid mine drainage making them unhabitable to both local
and migratory species.
Criterion (f) for a minor
EA amendment application is satisfied if the application involves an addition to the surface area for the
relevant activity of no more than 10% of the existing area.
The EP Act defines 'relevant activity' for an environmental authority as the environmentally relevant
activity the subject of the authority. Environmentally relevant activities include resource activities, which
include mining activities authorised under a mining tenement under the Mineral Resources Act 1989
(Qld) (MR Act). Under section 19A of the EP Act, activities related to or connected with a resource
activity are authorised by the issue of the environmental authority for the resource activity. Accordingly,
the issue of the EA authorises related and connected activities which support the mining activities in
the mine domains set out in Table A1 of the EA, and which can be carried out by Heritage Minerals on
areas with surface rights granted under the MR Act.
