A relatively common and widespread late-stage mineral, gypsum occurs as small vein-fillings, crusts, and rarely as colorless, twinned, prismatic crystals up to 5 mm long, typically associated with goethite, melanterite, jarosite and hexahydrite.

A common post-mining deposition in old workings of the mine, hexahydrite is found as thin, opaque, white crusts and powdery coatings associated with starkeyite and epsomite.

Hexahydrite occurs as opaque white pseudomorphs and powdery masses after epsomite, which readily re-hydrate to epsomite.
