$ 295
Yanacocha Mine
Cajamarca Mining District
Iron sulphide and/or Covellite
Mineral # 3056
The specimen has very distinct areas of black and gray.
The black mineralized patches are sulphide zones with pyrite and quartz with smaller amounts of enargite, sphalerite, and galena.
The gray areas show the rock that is supporting the minerals.
These gray areas are volcanic pyroclastic rock consisting of andesite, dactite, hornblend- pyroxine porphyry.
Expose this specimen in bright light some of the black mineralized areas are bright blue due to the presence of iron sulphide and/or covellite.
There could be some digenite along the edges of the ore.

Mineral # 3058
3 x 6.5 x 14 cm 680 grams
$ 695
This specimen is a half core. This specimen shows a good view of matrix rock in the Yanacocha Mine.
There are delicate veins of ore passing through the core and toward the one end this is a fine covellite exposure
which is always blue leaning toward purple. The best view of Yanacocha ore is seen by looking at the end of the
core specimen adjacent to the covellite exposure. This end view shows why this mine has been
so profitable. What you are seeing is bright mineralization composed of silver bearing enargite,
copper, and gold. Although gold is almost never seen outright in this mine due to its fineness, but gold
virtually present everywhere this mine.
