Early, I do not think both circuits are operational - one is with 600K? Last I read, there wasn't enough ore to run this one circuit at 24/7?

When you read this para with the next one, what they seem to be saying is that they are trying to establish sufficient ore supply to maintain continuous production at the plant. When you read these two paras together I think what they are saying is:

a) both circuits are now operational (ie 1m tonnes pa)
b) there is not enough ore supply to maintain 24/7 production at the plant
c) they are trying to get the ore (which is there) to feed the plant 24/7

That is why I was after pre-listing documentation to tell us whether the plant was running 24/7 (600K at 24/7 will be ok for now) and exactly what resources we have.
