It seems to me that they hope to negotiate at a higher price if the product can achieve a quality above 58%-62%Fe，or so they hope（judging by the waste ore feed,20% transform up to 58.5%，they seem to think for a standard ore of 25%-35%，58%-62% is the baseline of the end result），I think they are in negotiation with BMM saying what if the product is above 62%，could we possibly and probably sell it to you a little bit higher than 52$?BMM said we will see about that，show us the product first，what`s why the PO was pushed back a week or two.
Just my opinion.
