Ann: March 2018 Quarterly Report clarification, page-10

The extra ORE mined makes it harder to work out pricing, not knowing how much is being stockpiled. May be intentional? GXY would have known they wouldn't need to release too much this quarter due to becoming a producer / ASX rules.

It really does sound like part of the offtake agreement is to keep it quiet. I'm guessing there will be a good reason for all of it. Time will tell.
