Did anyone else notice the bit about permeability on slide 18, where for the Leichhardt colliery coal shrinkage on production results in permeability going from 0.1 to 500 mD !!!!
They suggest Blackwater might do the same thing!!!
Probably unwise at this stage for those of us geologically and coalwise illiterate to read too into the "low permeability" descriptors - better to let the reserves cert. progress do the talking.
