Operation type: Unknown
Development status: Prospect
ore: Cassiterite, Chalcopyrite, Galena, Sphalerite, Stannite
gangue: Calcite, Fluorite, Idocrase, Magnetite, Pyrite, Pyrrhotite
model: 43: Sn skarn
alteration: All of the veining in the area can be considered a type of alteration in the outer fringes of a significant hydrothermal system. This includes fluorite, laminar magnetite-fluorite-idocrase, and the sulfide-rich veins. Dolomitization is also locally devloped but it is not known how this is related to mineralization.
