The Wauseca Mine is the type locality for the Wauseca Pyritic member of the Dunn Creek Slate. This pyrite- and graphite-rich black slate signals the bottom end of the iron-formation throughout the region. It oxidizes rapidly when exposed to air, so that stored drill cores of it turn to dust. It had been known to catch fire when exposed in mine workings, and its dust was damaging to miners' lungs.
