I can't comment on which would be better out of investing 11M in chocolate startups or 11M in MBN to continue production, I would have to see the terms first. Objectively if they have very limited funds they should choose what is best for the region (since it is assumed they don't HAVE to pay it out)
It is without doubt that 11M in chocolate is a long term pay off, it will take time to transition, 11M to save a large mine and significant tax payer now to weather the current storm that may subside is significant, as you said it is only 3% of the 2014 profit (I haven't verified), it would seem that therefore a small outlay now would continue to deliver money to locals in saleries and contracts immediately, and, provide possibilities for large returns in taxes over the coming years.
I hope the best for the locals and the mine. And selfishly for me.
I appreciate you bringing balance to the debate though @jantimont
