GW - I would say you nailed it! Sounds about right to me.

"So what they are saying blatantly is..."we get the gringoes to build the mine...mine the gold...force them to sell 70% of it to the Vz bank at the absurdly low currency exchange rate....then the bank turns around and sells it for dollars on the open market thereby taking the profit that rightfully belonged to the gringoes that built the mine...the sewers..the hospital...the clinic...etc., etc." Of course the gringoes did all of the mine development, environmental impact studies and social projects without a dime from Vz under the false belief that they would actually make a profit down the road before the rules of the game were changed at the last minute after delays that drove them to the brink of bankruptcy."
