These, first briefly described by Knopf (1914), included linarite, caledonite, anglesite, wulfenite, hemimorphite and cerussite.

Colorless, transparent, complex crystals (to 2.5 mm) of anglesite occur with brochantite, caledonite, chlorargyrite and linarite in cavities at the Reward mine.

Existing mineral nomenclature already displays a number of examples of unfortunately similar names that are easily confused; names such as celadonite and caledonite, or mallardite and malladrite can easily be misspelled; names such as rhodesite, rhodizite and rhodusite are euphonically very similar.

Moreover, many interesting copper and lead alteration minerals, such as susannite, caledonite, linarite, langite and shultenite (P.O., to be published) have been observed.

Veins of galena follow irregular fractures in the breccia, and minor amounts of copper sulfides associated with the galena are altered principally to linarite and caledonite. The galena shows lesser alteration to anglesite.
