Q&A with Xuan Nyugen - Mine Rehabilitation begins during Feasibility Study Stage

  1. 1. Mine Rehabilitation begins during Feasibility Study Stage Transcript of Interview with Xuan Nguyen, Senior Environmental Manager at WA Department of Mines and PetroleumMining IQMine closure today is less of a technical challenge, and more of amanagement one. One part of this evolution is the integration of mineclosure practices to everyday practices. What are the best practices tothis?The best practice principles for mine closure planning are outlined in the StrategicFramework for Mine Closure (ANZMEC/MCA 2000). In addition to being anintegrated process, mine closure planning should start upfront during the feasibilitystage of a mining project. The planning process involves internal/externalstakeholder consultation, provision of financial resources, progressive rehabilitationand a risk based approach.How do we actually forecast the long term and hidden costs involved inthe closing and rehabilitation of a mine site?Mine closure costing should be estimated up front as part of the closure planningprocess using a transparent and verifiable methodology and process, and the costingshould be updated regularly and further refined as the mining operation progressesand more information become available. Costing should allow for hidden costs suchas project management costs, research and trials, post closure monitoring andmaintenance (including mobilisation of equipment).Where are you looking towards for case studies or successful examplesof mine closure and rehabilitation?There are some examples of successful mine closure and rehabilitation of bauxitemines in the Southwest of WA.How do we measure the sustainability of a mine’s environment duringoperations? What do you think are the best tools and strategies here?The presence of a mine closure planning process and how well this process inintegrated into the mine planning and operational planning processes. ICMMprovided a tools kit for mine closure planning (2008)
  2. 2. How do you successful communicate with external stakeholders toovercome adversity in mine closures?Identification of agreed post-mining land use and closure objectives upfront, on-going engagement with stakeholders throughout the life of a mine and a good riskcommunication strategy in place to ensure a meaningful consultation processThere’s constant change in the legislations relating to closure plans,how are you keeping up to date on this and how do ensure your internalstakeholders comply with regulations?On-going communication/dialogue with regulators and internal stakeholdersthroughout the life of mine.What do you think are the major obstacles to successful mine closureand rehabilitation? How can companies overcome these?Lack of proper closure planning process up-front, so not enough time or budget todeal with closure issues before a mine is closed, or cost blow out at the end.Xuan Nguyen is speaking at the Mine Rehabilitation and Closure to beheld in Brisbane in June 2011.
