yes, have invested in NSE previously.
There are a few in this space.
BUL caught my interest years back when they said hey had the 2nd highest acreage (junior explorers) in QLD CSG after PURE.
But they have suffered from very slow progress imo.
I am now looking closely at WCL and MPO as my top picks, close to low 30s.
BUL I have crossed off list.
