"Is there anyone on this board that will be able to have a look at the BFS and have a good idea about what an approx. fair buy out price would be.... Or is there still not enough info in that to be be determined "

The BFS should provide the absolute minimum of what SC is worth. And then like the other posters said, there is the question of TCK's backin percentage, value of additional metals in areas outside of SC, other considerations such as stable political environment etc. etc. that would not be in the BFS.
