Location: This district is in northeastern Kern County about 15 miles N of Randsburg, 10 miles S of Inyokern and 5 miles S of Ridgecrest. It was organized in the 1890's, and the most active period was in the early 1900's.

Geology: The area is underlain by Mesozoic granitic rocks containing small pendants of metamorphic rocks and cut by many dikes. Acidic dikes are most common to the E but become more basic to the W. Numerous faults are present. A number of narrow, north-trending quartz veins often cut the dikes. The ore contains free gold with varying amounts of sulfides and manganese oxide. Milling-ore usually averages ½ ounce or less of gold per ton, and the ore shoots usually are narrow with short stoping lengths.

Mines: Apple Green, Bellflower, Broken Axle, Butte, Crown Cons., Gold Bug, Gold Pass, Hillside, Huntington, Indian Wells Valley, Jerry, Lehigh Valley, Lost Keys, Northern View, Prize, Rademacher, Red Wing, Stardust, Star Lode, Stellar Group, Townsend, Vera Queens, White Star, Wildcat, Yellow Treasure.
