The wurtzite came from Block D of the mining area, and was associated with tanzanite or alabandite (a manganese sulphide, MnS).
Manganese sulphide occurs as the mineral alabandite (MnS) in concentrations from 11-20%.
Pale yellow dodecahedrons of spessartine to about 1 mm and black veins of alabandite are commonly found on these specimens.
Occurrence: Associated minerals are: enstatite, ferroan alabandite, troilite and daubreelite.
Relationship to o ther species: An hexagonal polymorph of alabandite.
Alabandite was first reported from the Butte district by Hewett and Pardee (1933).
Alabandite has been found at the Molinello mine, in the deepest part of the deposit.
Associated minerals are: pyrrhotite (Ti- and V-rich), ferroan alabandite, marcasite (Ti- and V-rich), wurtzite-2H (Mn- and Fe-rich), corundum, phlogopite, rutile, monazite-(Ce) and a graphite-like mineral.
Massive black alabandite has been found in a tunnel connecting the Verchniy and Nikolaevskiy mines.
3) Sulfosalt stage: alabandite, marcasite, pyrite, arsenopyrite, quartz, manganaxinite, clinozoisite, stibnite, robinsonite, jamesonite, barite, orpiment, realgar, hutchinsonite, geocronite, native arsenic, seligmannite, Pb-As-S glass ("revoredite," not a true mineral).
Late-stage mineralization on the northern margin of the deposit is represented by Fe-Mn-rich sphalerite, wurtzite (both the sphalerite and the wurtzite are deep brown in color), alabandite, rhodochrosite and rhodonite.
