As received moisture is 7.8 Note : Coal qualities reported for Coal Reserves vary from the qualities reported for Coal Resources see Table 4.2 due to two principal factors. Firstly, the Coal Resource qualities are based on the total Coal Resource while Coal Reserves qualities are only for coal within the Mineable Pit Shell. Secondly, Coal Reserve qualities have also been modified by coal losses and dilution factors. A-52
