1 cave was expected early 2018 the other waiting on an update . they've mobilised more jumbo's for remedial work
basically as i understand block cave is literally that they undermine a huge area then controlled blast or similar for it to collapse upon itself , a heap of structural engineers will be working on it at the moment which think the next update is end of this month , early next
