mine / mine Mines often take the form of a hole in the earth. Once earth materials are removed, sorted, refined, and reified into minerals they have commercial value. Things with this kind of value can be owned. Things that are mined can become mine. In Washington County, Utah there are a number of gypsum mines. Also there, is the Dwarf Bearclaw-Poppy, a plant endemic to that area. It grows only there in gypsum-rich soils and, partly due to gypsum mining, was one of the first federally listed endangered species in the U.S.
