Good observations. You're probably right about a general press release when the DP moves to Lemba. I'd expect the JDA to relase info too, especially if it's positive. Their's might be more informative and probably with a positive spin. Also, STP wants the attention (if oil results are positive) to feed into their EEZ auction which may come out next year.
One way or the other, official news will come out when it does and of course rumors too. IMO, if the wells prove up like we hope, ERHE will be considering a buyout offer inside the next 6 months.
Best to you,
