Localities

At the type locality, the Kawazu mine, Rendaiji, Shimoda City, Shizuoka Prefecture, Japan, kinichilite occurs as a hexagonal prism less than 2 mm long in the oxidation zone of a low-temperature gold - silver - tellurium quartz vein (AM 67.621-624, Mindat).

At the Upper dumps, North Star Mine, Mammoth, Tintic Mining District, Juab County, Utah, USA, a single specimen of kinichilite was found. The purplish brown crystals range from tiny bundles of fibrous crystals to single, elongated hexagonal prisms (MinRec 55.2.209).
