support and on site accommodation and training to local farmers and employees wishing to improve their farming skills and practices. Upon completion of the course, each participant was assisted with seed, fertilizer and technical advice for two planting seasons. Farmer groups were also established to provide ongoing support to village farmers. Post mine closure the training centre has been converted into an Agricultural High School with boarding facilities which currently has over 100 students enrolled from surrounding villages who are completing a nationally recognized 3 year course for Senior High School. In addition to the training centre, KEM in cooperation with local farmers also supported the establishment of approximately 450 ha of rice plantings prior to the closure of the operation. There was considered necessary due to high risk of food shortages which were predicted to occur around closure due to the dependency on mine income and decrease in rice farming which had occurred during the operation of the mine. A post closure Endowment Trust Fund of US$13.4M has been established in an off-shore account in Singapore which generates approximately US$600,000 per year. This fund is used to support the ongoing activities associated with monitoring and maintenance of permanent mining-associated structures within Protected Forest and also to provide ongoing administrative and maintenance support to the Agricultural High School. It is intended that these funds will operate in perpetuity in accordance with the agreements and governance arrangements negotiated by the Mine Closure Steering Committee.

Closure planning The quality of mine closure planning will become apparent once the last tonne of ore is passed through the crusher and it is turned off. At this stage the key people on site will be (ideally) the closure manager and the closure team, including the planner who created the master plan, sequencing all of the activities, tasks and resources required. The key for a successful implementation is to follow the plan. By continually reviewing the plan, and rescheduling activities and resources, the deadlines can be met and, more importantly, costs controlled. This will ensure the closure tasks can be completed on time and within budget. At most sites, all infrastructure and plant will be removed, the site re-contoured and revegetated, with a small team remaining to carry out ongoing environmental monitoring and maintenance programs. An example of good planning, team building and cooperative partnerships with the community is the closure of the Mt McClure gold mine in Western Australia. The Mt McClure project had several owners before it came under the control of Newmont in 2002. The mining operations consisted of a standard carbon-in-leach processing plant with multiple pits and two tailings storage facilities. In planning for the full decommissioning of the project, a risk assessment was undertaken by the closure management team with external consultants to focus on key issues and form the basis of the closure plan. This was followed by a stakeholder consultation process to further develop the plan and the creation of a process map that outlined in detail the planning steps and sequences (see LP Closure p.44).
