Exploration and site history

• Loc_Pt: "The Apex Mine (also called the Dixie Mine) is located on the east flank of the Beaver Dam Mountains in Washington County, Utah, about 22.5 km west of St. George and 9 km north of the Arizona border. The main adit is at an elevation of 1,656 m, lat 37?4'11"N. and long 113?48'14" W. (NE 1/4 SW 1/4 sec. 6, T. 43 S., R. 17 W.)." (Bernstein (1986))
• Loc_Pt: “The old mine workings consisted of 2 adits, eight levels of tunnels, an inclined shaft and a vertical shaft. The mine was developed to a depth of 1440 feet below the vein outcrop.” (Olsen and others (1988))
• Active — The mine was in intermittent operations from 1884 to 1962, producing Cu-Pb-Ag with minor amounts of Au, Zn (unreported), 1884–1986 (Bernstein (1986))
• Discovery — Significant amounts of Ga-Ge were discovered in the 1950s, 1950–1959 (Olsen and others (1988))
• Active — The mine went into operation as the world's first primary producer of Ga-Ge, 1985–1986 (Olsen and others (1988))
