This was recorded likely in the back half of 2010 sometime

Also, there is a separate print interview of Hassan made last fall which goes into a bit more detail regarding the oil seeps, how they were found, etc. While I can't provide a direct html link for that one in particular due to it's complexity, you can easily find the article by google searching the terms " Hassan Hassan" and "Simba" together. It was part of a light promotional effort by stockpedia.com UK
I checked the youtube link posted above and I while I believe the URL is correct for some darned reason it's not working, But the TV interview is out in "youtube land" someplace. If you google search Hassan / Simba Energy / youtube videos, I'm sure you'll find it fast if you've a mind to.
