Same coal quality, as expected. Things like ash content can change laterally within a deposit depending on depositional environment but this coal quality is dominated by its low rank, which isn't going to change much. It will be similar coal quality all over the deposit.

What I liked was those trench photos. That coal appears to be within 5m of the surface. If they can find a decent thickness of coal that close to surface they might have a project.
