Maca for open pit and Pybar for underground are excellent choices IMHO. I know nothing about the contractors for the tailings dam construction and the power station contract. Anybody know anything about them? Regardless, the mining operators are more important.

As an aside, I note that Pybar is certainly throwing their net wide and far over the last 12 months. Bad luck they are a private company otherwise I would buy some shares in them.

Cheers
