IMO timing is not right for NST to do that.
1. It would chew up valuable cash reserves which may be needed to develop POGO and added exploration
2. It would reduce their average profit margin - not a good look for existing NST shareholders
3. They don't need the infrastructure now. Maybe later.

NST will just keep a watching brief on EAR to see how they develop. EAR will need a much lower AISC in future or NST may need infrastructure to trigger a TO IMO.
