By the looks of it, not much! The previous Mariola Jorc announcement did quote
"A separate additional Exploration Target* of between 63.4 Mt to 80.6 Mt has been estimated in addition to the above Coal Resource, which represents considerable potential upside for the establishment of a further JORC Coal Resource at Mariola.", so maybe this is not a surprise and has been factored in (somehow!??). Could argue that they have not reached that estimate either.
