I'd say Lokichoggio and maybe a small part of Loima are in Block 11A. And the aerial exploration may be referring to Adamantine/Bowleven in 11B. I think they might be closer to that then ERHC.
apparently it was ERHC that will be starting aerial testing as mentioned in that Kenyan newspaper.
Unfortunately, the timing of this news has me concerned for the general health of the farm-out negotiations. But it's good to see ERHC is pressing ahead in order to secure the best deal possible, either with the current party or someone else.
