If they can prove up a resource at 1.1% and 80% recovery they should produce about 145kt of spod.
Opex of $350/tonne and sale price of $880 gives $102m per year. Half of which belongs to TAW. Take out prepayments from the revenue that theoretically would have been received, corporate costs etc and tax and you are probably ending up somewhere in that region of $25-30m a year. So I think that is a reasonable assessment.
