 | | The orebody at the Cerro de Pasco mine is estimated to have contained a total of 100 million tons of pyrite, 4 million tons of zinc, 2 million tons of lead (Petersen, 1965), in excess of 1 million tons of copper, 10 thousand tons of silver, and lesser amounts of gold and bismuth. |
 | | The Cerro de Pasco orebody is associated with a Tertiary volcanic vent which is located in the core of a broad, northplunging anticline composed of highly contorted shales, phyllites and quartzites belonging to the Devonian Excelsior Group (McLaughlin, 1924; Jenks, 1951). |
 | | Cerro de Pasco was noted for having fine specimens during the first half of this century, but only a few of them made their way into museums and private collections. |
