Definitely the recent share price rise is a clue. And perhaps a part of the reason for a TH. I don't think they used a TH to announce the cement job mishap ... so if this is another mishap - why not just do the same as then and just announce it, without a TH.
The last TH this company did was prior to the "Largest Gas Find in Australian History" announcement!

Obviously they are doing some analysis regarding "deliverability" ... now that word does worry me a little when I look at it in isolation.
Why not say "size"....
Are they saying that the gas may not be deliverable?

I think the word "potential" helps. Why say "potential deliverability" - that word potential implies "size", so we may be getting a huge result here....
Without the word potential - I would be concerned - but with it - not so much!
