Mine Closure - Feasibility Study
Western Australia
Calibre QuadR completed a feasibility study for the closure of an underground mine in July 2020. Outcomes of the feasibility study have contributed to a detailed plan for the closure of the underground mine to facilitate the relinquishment of the site. Calibre QuadR has since been engaged as the integrated delivery partner to deliver the underground mine execution project based on the completed feasibility study.
Closure execution activities reviewed during the Feasibility Study include but are not limited to the key activities outlined below:
- Demolition of all process and non-process infrastructure including disposal of demolition waste either offsite or in onsite landfill
- Waste rock dump (WRD) landform earthworks
- Tailings storage facility (TSF) landform earthworks
- Landform earthworks throughout the disturbed footprint of the site
- Investigation and remediation of contaminated sites
- Installation of seepage management infrastructure for the WRD and TSF
- Seed collection and production of tube stock
- Seed spreading
- Infill planting
