For clarity, there are no fee for announcements. ASX fees are allbased on number of shares on issue, nothing to do with individual or number of announcements.
I do not foresee anything material happening by 31 March (Quarterly), so agree with scottm the first announcement (excl the 1/4ly) will be whether Cronimet is in or not.
Quick ride down if not and sustained wild ride up if they are in!
