As for the DD squad from Oz: a second opinion is always a prudent idea. But Hebei is not some dumb Chinese company that needs the Aussie engineers to tell them what to do.
Unlike some other Chinese steelmakers Hebei is in fact an iron ore miner. They know the business. They produced nearly 8 MTA of iron ore concentrate in 2012 from deposits that averaged 30% FE. Interesting that those numbers correspond exactly with Kami's production profile. Hebei must see something very familiar about the Kami deposit.
