Many of the abandoned buildings and old infrastructure at the Mount Morgan Mine are now beyond
repair, given prolonged exposure to the elements. Wet and dry rot in timber structures, corrosion of
steel structures, termite attack and building collapse have been observed in various structures.
6.8.2.2. Impact Assessment
Historic heritage sites are present within Mount Morgan MLs however not within the Upper Mundic Gully
TSF footprint. All landscape within the heritage listed area is subject to heritage exemption approval as
detailed in the Heritage Agreement currently in preparation.
6.8.2.3. Management Practices
The Heritage Management Agreement sets requirements for undertaking operational activities at the
Mount Morgan Mine. Heritage Minerals will comply with all requirements of the Heritage Management
Agreement.
6.9. Nature Conservation
The flora and fauna impact assessment is only applicable to the amendment relating to the Upper
Mundic Gully TSF. The two other amendments will have no impact on flora and fauna.
6.9.1. Significant Residual Impact Assessment
With consideration given to each species overall distribution, the regional availability of suitable habitat,
the historical disturbance of both the project area and its immediate vicinity, and the proposed actions
to mitigate residual impacts, the project is not anticipated to result in a significant impact on any state
listed flora or fauna species assessed. However, the project is likely to have a significant impact on
Regulated Vegetation – Category B ‘Of Concern’ RE 11.10.2 present within the project area.
Significant Residual Impact (SRI) assessments were undertaken for MSES threatened species that
were ‘Known’ to occur or considered “ Likely” to occur or has a ‘ Possibility’ to occur within the project
area. One MNES species, Northern Quoll, was assessed under the federal significant impact guidelines.
These matters, their likelihood of occurrence, and the result of their significant residual impact
assessment are discussed in Table 43 below. All impact assessments are available in Appendix M.
As stated in the Queensland Environmental Offsets Policy: Significant Residual Impact Guideline (DES,
2014), an action is likely to have a significant impact on endangered or vulnerable wildlife if the impact
on the habitat is likely to:
• Lead to a long-term decrease in the size of a local population; or
• Reduce the extent of occurrence of the species; or
Fragment an existing population; or
•
• Result in genetically distinct populations forming as a result of habitat isolation; or
• Result in invasive species that are harmful to an endangered or vulnerable species becoming
established in the endangered or vulnerable species’ habitat; or
• Introduce disease that may cause the population to decline; or
