Detailed Mineral List:
| ✪ Azurite Formula: Cu3(CO3)2(OH)2 Habit: Tabular to tapered groups Colour: Very dark blue Description: Mostly massive, found in massive quartz with massive chalcocite, malachite, fluorite. |
| ✪ Baryte Formula: BaSO4 Habit: massive tabular, subparallel overgrowths with curved faces, short prismatic to acicular Colour: white, creamy tan, blue, yellow, colorless Fluorescence: rarely yellow-white, or blue-green primarily under SW Description: There appear to be three generations of baryte crystallization: 1) an initial coarse-grained, tabular to massive, opaque white phase in massive quartz and fluorite, 2) a translucent, creamy tan overgrowth phase usually in subparallel orientation on the white barite in voids within the previous matrix, some from the dissolution of fluorite, and 3) a transparent, colorless to blue overgrowth phase on either phase 1 or 2 baryte crystals, or isolated. All three phases of crystals can show varying degrees of surface etching. Small tabular white crystals and yellow, transparent, acicular crystals are also known. |
| ⓘ Chalcocite Formula: Cu2S Habit: massive Colour: black Description: Associated with massive quartz, fluorite, romanechite and copper secondary minerals. |
| ⓘ Chalcopyrite Formula: CuFeS2 Habit: massive Colour: brassy Description: small blebs |
| ⓘ Chrysocolla Formula: Cu2-xAlx(H2-xSi2O5)(OH)4 · nH2O, x < 1 |
| ✪ Fluorite Formula: CaF2 Habit: cubic with tetrahexahedral overgrowths Colour: colorless, pale blue, purple, green |
| ⓘ Goethite Formula: α-Fe3+O(OH) Habit: massive, earthy Colour: dark brown |
| ⓘ Hematite Formula: Fe2O3 Colour: red Description: earthy red massive material, dissolved in HCl with positive results for iron (as opposed to copper) |
| ⓘ Malachite Formula: Cu2(CO3)(OH)2 Habit: radiating acicular, mossy aggregates Colour: green Description: alteration of chalcocite, typically with azurite in massive quartz and fluorite |
| ⓘ Pyrite Formula: FeS2 |
| ⓘ Quartz Formula: SiO2 Habit: drusy Colour: white Description: Massive matrix for much of the mineralization but despite its abundance, only tiny drusy crystals present |
| ⓘ Romanèchite Formula: (Ba,H2O)2(Mn4+,Mn3+)5O10 Habit: botryoidal Colour: very dark brown to black Description: As masses with conchoidal fracture and black streak in quartz with azurite and malachite. Analyzed 2016 by Peter Cristofono and Tom Mortimer using EDS. Closest other analytical possibility is hollandite, which has a slightly higher Ba:Mn ratio, and doesn't match the physical properties of this material as well as romanechite does. |
| ⓘ 'Soapstone' |
| ⓘ Talc Formula: Mg3Si4O10(OH)2 |
