Cerro Rico's Silver production has never been matched.......

When one compares Cerro Rico to other BPV deposits, three features stand out as being exceptional:

* The phenomenal silver resource. Cerro Rico has produced almost five times more silver than any other BPV deposit.

* Development of a thick acid-sulfate lithocap. The acid-sulfate lithocap at Cerro Rico is at least twice as thick as any other described from a BPV deposit.

* Development and preservation of a particularly deep zone of oxidation. This is almost four times as thick as any other developed at a BPV deposit.
