My industry - that's how it was in the UK 40 or 50 years back, though most of the real metal, me included, were doing DOHA or Saudi in a Ford Transcontinental. Anyway Dai, Dirty Lyle still probably has our backs here...
I'm assuming you mean pre-TD, as opposed to drill. Reaching TD will be no SP mover imo, unless positive helium show RNS towards the end of next week. It's the third week that'll really count imo and certainly from Wednesday 11th.
I have to say I have never managed to get a quote, on any exploration stock that has gone feverous on the opening bell after a very positive RNS. As RJ says, by the time you've got a quote it's already 30+% up. Yeah, no risk if you can get in, but stuff that...
Indeed re the 'Discovery' part. Reference is drawn to the shocking Desire Petroleum oil to water scenario some 13 years back, which was a classic (and most definitely intentional) misrepresentation of reality and thus lead the market 'up the garden path'. They should've been in court for that imo!
