A monstrous specimen with the largest chalcopyrites I have yet seen from the locality. Perched upon them are disc-shaped, lustrous brown siderite crystals and spiking out from the chalcos are several fine quartz points. An EXCEPTIONALLY LARGE specimen for the locality and in remarkably good shape! What is more, it displays nicely despite its size. Somebody took a lot of care getting it out!
