We believe that South Africa is a prime exploration destination. We have had 52 exploration applications outstanding for a long time and now we’ve had 16 of those 52 licences granted and we are working hard to get the others approved. One of the strengths that we’ve got is that we have a database with fairly reliable information from about the mid-1950s onwards. Using that database we then apply the latest thinking and the latest technology. So a lot of our focus is around Kimberley where we used to mine.
