Firstly Loutcrop just for the record my brother would have forgotten more about geology than you would ever dreamed of knowing, secondly he's continually stressed to me about the difficulty of making a commercial discovery however he's also said MRD are a chance because they're continually getting the right rocks and some good indications.
They have some very good people working on their geological and analysis teams so taking all those factors into account they're a better chance than most but it's still exploration which is never easy if it was there would be mines everywhere.
Personally, right or wrongly, I have always just had a gut feeling they'll eventually find something and I prefer to remain positive rather than negative.
I have no idea what they've done but there's no doubt that to request a trading halt for the reasons that they did the news can only be positive so forgive me if I'm sick of Richard craniums either deathriding us or with an axe to grind continually running us down for no bloody reason currently.
