2.0 PRE-DEVELOPMENT: MINERAL EXPLORATION AND FEASIBILITY Figure 2.1 – Exploration drilling can produce significant sustainability impacts (photo – Roberts – DMR - http://www.mining.unsw.edu.au/kcmi/Govern/NSW_DMR_2.pdf) Key Messages a focus on community engagement and support during this stage will pay dividends for any future operation if the community engagement process is flawed, the approval to mine process will be delayed or threatened cross-cultural skills are essential in the early phases of a potential mining project mine planning and design needs to integrate social, environmental as well as economic considerations mine closure planning needs to begin in the early stages the earlier the life of mine planning begins, the fewer the problems later EIA and SIA studies should be completed in parallel with prefeasibility and later feasibility studies A GUIDE TO LEADING PRACTICE SUSTAINABLE DEVELOPMENT IN MINING 19
effectively applying risk management principles early lays the foundation for good relationships throughout the whole mine life cycle baseline studies need to be undertaken for – biodiversity – noise, air quality – water the potential for acid drainage needs to be assessed as early as possible and mitigation strategies planned. Introduction This Chapter introduces Leading Practice (LP) as a tool that, if used at the very beginning of the mining cycle, will set the scene for success in implementing LP throughout the subsequent development, operational and closure cycles. Topics covered include the mineral exploration and the feasibility study phases. Mineral exploration covers the initial phases of a prospective mine’s life. At this stage of the mining cycle, there are no guarantees that a mine will eventuate. In fact, mineral exploration rarely results in the development of a mine. However, in most cases, there will be environmental and social impacts that will need to be addressed including access tracks, drill pads, disposal of wastes, and community concerns and expectations. Mineral exploration and evaluation techniques range from the most environmentally benign, such as remote sensing from satellites, to the more invasive, such as close spaced intensive drilling. Environmental planning and management offer their greatest benefit when preventing, or at least minimising, environmental impacts by: promoting environmental awareness within exploration companies; educating and training employees and contractors; and developing and applying industry codes of practice (Environment Australia 1995). Exploration activities have the potential to adversely impact on the environment if they are not managed appropriately. Aspects that require management include: Clearing of vegetation and other types of disturbance to fauna. Soil erosion and stream sedimentation. Spreading of weeds. Noise, light and dust level. Disturbance to culturally significant sites. Disruption to other land users, such as farmers and the local community. Contamination of soil and water and. Injury to, or detrimental effects on the health and wellbeing of employees, other persons at work and the public. 20 LEADING PRACTICE SUSTAINABLE DEVELOPMENT PROGRAM FOR THE MINING INDUSTRY
