I thnk you are right in saying that OW offtake is applicable to the output of the MPP (60%), I don't think that an offtake agreement is in place for the native copper
BUT
I a very dubious about the possibility of there being 3mt of DSO available at Rocklands. The reference to a Sinosteel offtake agreement for 3mt is clearly a mistake and was in reference to the contract for the 3mt MPP
