Notes:
1 The estimated exploration target coal quantity and quality is conceptual in nature, there has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
2 The quality are preliminary and conceptual, ranges are only based on sample qualities that were sampled from 7 boreholes, 7 coal outcrops and 3 test pits.

Mt = Million tonnes
ar = as received
