Magnitude Mines and prospects


A former W mine located in the SE¼NW¼NE¼ sec. 14, T9N, R17W, SLM, 2 miles S of Rocky Pass, on patented (private) land within a Bureau of Land Management administered area. The USGS MRDS database stated accuracy for this locality is 100 meters.

Magnitude:

The Magnitude property in the Grouse Creek Range, Box Elder County, contains the oldest tungsten workings in the area and comprises a single claim owned by Urban Puyuelo. The claim is about 5 miles north from State Route 70 on the Rocky Pass mine road; this road is 1.2 miles east from the Lone Pine mine road. Several mine workings around the Magnitude mine were included with property known as the Frank Edison mine during World War I. Scheelite occurs in a tactite zone at the contact of quartz monzonite and limestone. The limestone is a thin member of a thicker sandstone-quartzite bed. Mine workings consist of several opencuts and a shaft 25 to 50 feet deep. Total production has been about 300 tons of ore containing an estimated 250 units of WO3. The mine was leased b y Massae Mining Co. between 1940 and 1944 and by Rocky Pass Mining Co. between 1952 and 1955. Urban Puyuelo sold 1,300 pounds of ore to C.W. Jones of Bishop, Calif., in 1954. No reserves have been developed, but ore has been obtained from the mine when the price was especially attractive, and probably small quantities of additional ore could be produced under favorable economic incentives.


Mineralization is a W deposit hosted in the Eureka Quartzite and limestone of the Pogonip Formation. The ore body is tabular at a thickness of 1.22 meters (4 feet) and with a depth to top of 0.0 meters. Controls for ore emplacement included favorable limestone beds along an igneous contact. K2 Compton and other (1977), call this intrusion granodiorite verging on adamellite. Associated rocks include Pliocene-Late Ordovician diorite of the Grouse Creek Pluton Or Emigrant Pass Intrusion. Local rocks include Devonian sedimentary rocks in western Utah.

Workings include surface and underground openings comprised of many short adits, open cuts, and shallow inclines scattered over 160 acres.

Production statistics: Year: 1973 (period = through 1973) (estimated): 223 metric tons of WO3.

Analytical data result: 2-foot chip sample yielded 0-.55% WO3.
