Correct - extreme rain events take out a few (i can check but guess would be 10-14) days per year and very low levels in dry season (mostly July-October but random periods any time) take out 120-150 days per year hence need to get a stock pile started at Buntok ASAP.
We currently have regular barge access with small 800t barges between Krajan (Pit3) and Batu Tuhup. This also can be halted at very low levels. Road access is established from restoring old logging roads but grades mean volume per trip is suboptimal at present and road improvements will involve lessening steep sections or bypass. I'll add that IMHO the major bridge on the road will also need upgrading once high volumes are moving
