Detailed Mineral List:

Baryte
Formula: BaSO4
Calcite
Formula: CaCO3
Cerussite
Formula: PbCO3
Habit: Small prismatic crystals and small clusters, the later almost always twinned.
Colour: Usually chalky dull white on surface from weathering, translucent grey-white interior.
Description: Likely more prevalent and better specimens in active mining days. Collecting on the small remaining dumps yielding obvious but not impressive specimens.
Chalcocite
Formula: Cu2S
Chalcopyrite
Formula: CuFeS2
'Chert var. Novaculite' ?
Description: The cited reference gives a question mark after the term "novaculite". See my messageboard discussion for May 20, 2019. The rock is highly improbable to be sedimentary, hence a variety of chert - a strictly sedimentary rock term - does not fit. Rather the abundant material being referred to is almost certain to be rhyolite. The largely uniform light grey color reduces the amount of interest in it as a lapidary material, but it can and has been used for that.
'Chlorite Group'
Covellite
Formula: CuS
'Freibergite Subgroup'
Formula: (Ag6,[Ag6]4+)(Cu4 C2+2)Sb4S12S0-1
Galena
Formula: PbS
Gold
Formula: Au
Malachite
Formula: Cu2(CO3)(OH)2
Muscovite
Formula: KAl2(AlSi3O10)(OH)2
Muscovite var. Sericite
Formula: KAl2(AlSi3O10)(OH)2
'Psilomelane'
Pyrite
Formula: FeS2
Pyromorphite
Formula: Pb5(PO4)3Cl
Habit: Highly diverse. Includes tabular with basal pinacoids all the way to slender prismatic with complete pyramid faces. Some of the later had yellow equant second-generation crystals attached epitaxially to the long colorless prism - "corn on the cob"! Also "spindles", "barrels", "rice grains", and acicular spheroids.
Colour: Every color reported for the species. Shades of green of course, also water-clear colorless, beige, tan, yellow, orange, white. But of special interest is the unique carnation pink crystals. Unfortunately these appear to be due to F-centers or lattice voids and not a chromophore. So they quickly fade in the sunlight.
Description: See details under habits and colors. This is a much smaller mine than the nearby Silver Hill Mine. But this mine surpasses Silver Hill in the amazing diversity of colors and habits of the pyromorphite.
Quartz
Formula: SiO2
Quartz var. Milky Quartz
Formula: SiO2
Siderite
Formula: FeCO3
Silver
Formula: Ag
Sphalerite
Formula: ZnS
Tremolite
Formula: ◻Ca2Mg5(Si8O22)(OH)2
