Black coatings of metacinnabar, some of it selenian
, have been identified at the lower workings by XRD where it is associated with cinnabar.
Other closely associated minerals are cuprian and palladian trogtalite, selenian
digenite and selenian
The most common silver-bearing species, a selenian
miargyrite, has been verified by both electron microprobe and X-ray diffraction techniques on samples from the 282-meter level.
