I am starting to wonder whether we will have a Trading Halt tomorrow, or if it was a success, simply an Ann with a declaration of discovery?
I am sure by now they know what they have down there, on many layers and I have a feeling that by open tomorrow, the samples will be to surface. (If they are not already?) Timing would suggest we are right at the point end now.
If they know, what is the point of halting?
Just a rookie question really - but interested in the opinions of you lads and ladies who know far more than me!
