Timing of pmts to service the debt vs. ability to make those pmts, and then what cash/liquidity position would look like after servicing the debt.
That is why BAA needs $100M, ASAP. They can not grow or mine their way out of it. They "may" have been able to if Namoya went online without a hitch - we all know how that turned out...
I'm interested to see how this all shakes out. I personally hope they use Twangiza as leverage as there is far less uncertainty there vs. Namoya. We shall see...
