That mining is for additional ore beyond what is already on the blastpad that is being processed through the plant now and trucked to Esperance for shipment on the 29th.
There was still another 90kt on the blast pad if I recall correctly. Previously there was 230kt if my memory servers me right. That tells me they're on track to do a good job of filling the ship
and may have some left over for a second in January.
Yes - we're gonna make it.
