Whitehaven Coal Limited : Annual Report 2012
Whitehaven Coal Limited -- Annual Report 2012 15 OPEN CUT OPERATIONS The Gunnedah operations include the Tarrawonga (70% owned by Whitehaven), Rocglen (100% owned by Whitehaven), and Sunnyside (100% owned by Whitehaven) open cut mines and the Gunnedah coal handling and preparation plant and train load out facility ('CHPP') (100% owned by Whitehaven). The Werris Creek mine is 100% owned by Whitehaven. Our open cut operations produced a solid result, although production was below planned levels due to exceptionally wet weather in both the December and March quarters. Floodwaters associated with high rainfall caused road damage, mine closures and significant in-pit water. Whitehaven's mines and equipment did not incur any direct damage and all mines were quickly brought back into production as floodwaters receded. Water management required ongoing changes to mine scheduling. In addition, planned mining was interrupted and production of coal reduced due to the reduction in explosives deliveries as a result of the Orica plant shutdown in Newcastle in November 2011. The Werris Creek mine was the most adversely impacted operation in terms of both weather and explosives supply. However, production at Werris Creek is improving steadily and production of approximately 2.0 Mt is expected in FY 2013. Following a substantial upgrade to coal resources and reserves and the extension of the Tarrawonga Joint Venture, an application has been lodged for modification to the existing Project Approval for Tarrawonga. This would allow production to increase from 2 Mtpa to 3 Mtpa and would cover mining of the full JORC reserve over more than 15 years. This application is progressing through the NSW planning process. A revised Project Approval was received from the NSW Minister for Planning for extension of the Werris Creek mine life, to cover the full JORC reserve at up to 2.5 Mtpa over 20 years. Approval has also been received to modify the Rocglen Project Approval to take account of modified geological information.
