Detailed Mineral List:

Antimony
Formula: Sb
Description: Small tin white microcrystalline masses associated with calcite, pyrrhotite, chalcopyrite, acicular stibnite and probable cubanite.
Reference: Ryan Eagle personal observation 2016
Arsenopyrite
Formula: FeAsS
Reference: Ryan Eagle Collection
Baryte
Formula: BaSO4
Reference: Ryan Eagle Collection
Bournonite
Formula: PbCuSbS3
Description: Usually as tiny tabular crystals associated with carbonate and clay in joint planes. Widespread but rare.
Reference: Ryan Eagle Collection
Calcite
Formula: CaCO3
Chalcopyrite
Formula: CuFeS2
Reference: Ryan Eagle Collection
Cubanite
Formula: CuFe2S3
Habit: Acicular
Colour: Brassy yellow
Description: Extremely fine matted aggregates of brassy yellow acicular crystals on pyrrhotite, chalcopyrite and native antimony. Initially suspected millerite, although SEM EDS analysis proved nickel to be absent.
Reference: Ryan Eagle personal observation 2016
Fluorapatite
Formula: Ca5(PO4)3F
Colour: Pale blue, white
Description: Found very rarely in quartz-carbonate veins. Usually very pale blue or white/colourless, only rarely displaying crystal faces due to lack of space to grow freely into. Fluorescent in LW UV.
Reference: Ryan Eagle Collection
Galena
Formula: PbS

Gold
Formula: Au

Pyrite
Formula: FeS2
Reference: Ryan Eagle Collection
Pyrrhotite
Formula: Fe7S8
