Wheal Jane at Kea was one of the few Cornish mines to produce large Pyrite crystals, mainly during mining operations in the 1970s and 1980s. This dense, solid aggregate of quite sizeable (up to 2.8 cm on edge) cubic crystals is not without some damage (chipping) to the corners, but it is remarkably fresh and still bright golden metallic, making it a fine survivor from this mine. Minor brown Siderite can be seen coating some surfaces of the Pyrite crystals and extending inside between crystals. Most of the outer surfaces of Siderite are brusied, or the crystals poorly formed.
