Whitehaven Coal Limited : Annual Report 2011
14 NARRABRI MINE Whitehaven (operator) 70.0%; Electric Power Development Co. Ltd 7.5%; EDF Trading 7.5%; Upper Horn Investments Limited 7.5%; Daewoo International Corporation and Korea Resources Corporation 7.5% Development of the Narrabri mine is proceeding as planned with construction of Stage 2 facilities and delivery of longwall and other equipment on schedule and budget. The Narrabri CHPP has begun commissioning and the upgraded ventilation fans and shaft are well advanced. Pre-drainage of CO2 from the coal seam is working well with confidence in gas extraction methods and gas modelling continuing to grow as the inventory of drained coal grows. Mining conditions underground are excellent and development rates have improved as skills and experience grow and as development has moved away from pit-bottom setup into normal main road and longwall gate road development. Some delays continue to be experienced in development as a result of the difficulty in recruiting experienced underground mine workers. However, at current development rates, commencement of longwall extraction is scheduled for February 2012. Development of the main gate and tail gate roads for the first longwall panel is on the critical path for commencement of longwall mining and progress against schedule is being monitored closely. Sales of more than 200 Kt of Narrabri coal have now been made, with coal stockpiling and handling systems working well and coal quality meeting expectations. Ongoing review of Stage 2 costs, including tendering for all major components of the work, has not identified any material change to the budget capital cost estimate of approximately $300 million (100% basis).
