If there is any relative over/under valuations between them I can see traders jumping ship, i.e. sell UKOG on a spike, pile in STG as it hasn't risen as much.
UKOG will get the news first? I think you'll find all HH plays will RNS at the same time.
They've gone extremely quiet on the gold front, inc. on Twitter when asked. To me that means RNS imminent 
Imagine if HH spud and gold RNS next week. This will rocket.
Clear run of good weather for over a week now. Should be a matter of days before rig is onsite and they will issue an update then imo.
There has been no new tweets from Lenigas today and none about HH for a while now.
