Production Of Calcined Magnesite

GABBS, Nev., in Nye County, is 140 miles southeast of Reno and about 31 miles north of the Southern Pacific railroad at Luning. The townsite lies at the eastern edge of Gabbs Valley, and plant and quarry operations are in the foothills of the Paradise Range at elevations from 5000 to 5900 ft. Hard-surfaced roads connect with main U. S. high- ways on the north and south. Historical Background: Brucite, a magnesium hydroxide mineral, was discovered in the Gabbs area in 1927 and magnesite, the magnesium carbonate, was found later on claims originally staked and worked for the tungsten mineral scheelite. The brucite is on a granodiorite contact and the magnesite is usually some distance away from the granodiorite
