Personally, I would not touch any stock in Africa at the moment. Simply due to the real risk of political, linked to religious, unrest. Or even worse, outright civil war. No one knows where the turmoil in the Middle East/North Africa will lead - and if they say they do, they should be working for the CIA.
With SSN, that is another risk you do not have to worry about.
By the way, I have thought of doing similar - except that I deliberately put all my money in O & G stocks and all in either the USA or Australia. So it is hard to sell anything, even for SSN at these bargain basement prices. I will give it more thought though.
