How long has the Mbalam-Nababa saga been running, and why is it that no one in two decades has been able to convert it? It's clearly one of the more complicated projects to convert, given it's magnitude. You don't extract 40Mt p.a over 15 or so years of DSO in a volatile African Nation without difficulty. ANS has been on the scene for less than 2 years putting together a China backed consortium to get the job done. It has NOT failed, so hold your venom until it has failed and you've lost your investment.
Because when they get this done, you're sitting on a multi-bagger of EPIC proportions. Maybe you don't want that outcome...
