Deposit: Water must be obtained from wells and power generated at the site. The present access road needs improvement. General location is about 82 km NE of wells. General size of ore body is large.

Deposit type: W veins

Development: Diamond drilling done

Geology: Indian springs tungsten deposit is located on the gamble ranch, near indian springs, on the eastern slope of the delano mts. Most of the high-temperature pneumatolytic quartz veins occur on eastern contact of the indian springs stock. The bulk of the scheelite occurs in the quartz veins rather than the nearby tactites. Diamond drill cores from the easier contact zone have shown quartz veins containing abundant pyrite and some molybdenite in pegmatite lenses, and near zones of potassic and sericitic alteration. Minor amounts of chalcopyrite are also present. Mineral exploration is currently being carried on on the property by utah international, a division of general electric corp. Scheelite in quartz veins
