Named in honor of Peter Godwin Embrey, an English mineralogist for the British Museum of Natural History in London, England. Embreyite is a rare mineral that occurs in Russia at the Berezovskoe gold deposit in the Urals region, in the Argent mine in South Africa, at the Callenberg North No.1 open cut in Saxony, Germany, and in the Le Cantonnier vein in Aquitaine, France. At its Russian locality it occurs on museum samples from the oxidized gold-bearing quartz veins. Associated minerals include crocoites, phoenicochroite, vauquelinite, cassedanneite, cerussite, fornacite, pyromorphite, and mimetite.

Named after Samuel Franklin Emmons, an American economic geologist formerly at the United States Geological Survey. Emmonsite is an uncommon mineral that occurs as a product of the alteration of tellurium minerals in oxidized, hydrothermal precious metal deposits. Localities for Emmonsite are in the United States including in the Clinton mine here in the Black Hills of South Dakota, Mexico, Honduras, Chile, and Armenia, among a few others.

Named for the Greek word enargis, meaning “vivid,” for its distinct cleavage. Enargite is a common and widespread mineral that occurs locally as an important copper ore. A few localities for well crystallized material include in Peru, Argentina, the Philippines, Taiwan, Japan, the United States, Austria, Italy, and Namibia. Enargite occurs in hydrothermal vein deposits and as a late-stage mineral in low-temperature deposits.
