No, it does not mean they have necesarily reached the milestones.
Step 1: What they are issuing here are the performance rights
which were approved at the February 2018 shareholder meeting.
Step 2: Then when the performance conditions are met the performance rights will then vest,
which means that each performance right can be converted into 1 share.
This stage is not probably not yet reached.
The January 2018 explanatory memorandum for the Feb 2018 shareholder meeting states:
(Conversion): Once the relevant milestones have been satisfied, each Performance Right will, at the election of the holder, convert into one Share.
(my bold)
It's great that we will know on Wednesday 18th April how close they are to meeting any of the milestones.
I would hope that the most recent weeks of gold production would be meeting one or more of those milestone rates on a pro-rata basis.
