Other mercury-bearing minerals identified from the mineralized veins include montroydite, schuetteite, calomel, gianellaite, mosesite, terlinguaite, eglestonite, metacinnabar, cinnabar, native mercury and the second world occurrence of donharrisite.
Eglestonite occurs as deeply striated cubic and dodecahedral crystals with a blocky habit, and as thinly elongated spears with apparent twinning.
It is generally associated with cinnabar, edgarbaileyite, eglestonite, montroydite, mosesite, szymanskiite and wattersite.
It is most commonly observed covering or attached to wattersite, native mercury, edgarbaileyite, eglestonite and cinnabar.
It generally occurs as dark-brown masses of subhedral crystals, although at least two euhedral, prismatic crystals have been found associated with eglestonite and montroydite in the lower workings.
Wattersite is commonly associated with native mercury, edgarbaileyite, montroydite and eglestonite.
Subsequent to this initial mineralization, small amounts of montroydite, eglestonite, wattersite, deanesmithite, edoylerite, edgarbaileyite, CCUK-8, and szymanskiite formed.
Here, the opalized serpentinite rocks contain thin coatings and veins of cinnabar with isolated native mercury and small quantities of eglestonite and edgarbaileyite.
Mercury minerals identified from the lower workings that probably formed after the cinnabar include eglestonite, hanawaltite, peterbaylissite, clearcreekite, calomel, terlinguaite, wattersite, edoylerite, deanesmithite, szymanskiite, and seven unnamed minerals.
When these mineralized silica veins are opened, they often reveal abundant native mercury and cinnabar, with minor edgarbaileyite, eglestonite, montroydite and wattersite filling irregular cavities.
