Abstract:
The Challenger gold mine (Challenger) is located in remote South Australia. Discovered in 1995, mining commenced in 2002. As a relatively new site with no mining legacies, Challenger provided an ideal site to plan the full lifecycle of mining based on digital mine planning, learnings from successful rehabilitation elsewhere, and the full awareness of industry legacy issues such as acid mine drainage, tailings storage and long term landform stability. This paper describes the key aspects that will impact the Challenger site post-mining, including: • Remote site. • Minimising the disturbance footprint. • Integrated management of tailings and waste rock. • Consideration of waste rock properties for landform construction. A key success factor for the Challenger site has been the progressive support of management towards sustainable mining. By adopting a life-of-mine approach, environmental considerations were incorporated at the inception of the project and have been actively managed during the life of the mine to the satisfaction of internal and external stakeholders. As a result, the operation has a very clear and concise plan as the operation matures and eventually moves towards closure. Adopting a fit-for-purpose, consistent approach to sustainable mining has resulted in cost-efficient environmental activities and confidence around the cost for mine closure.
