Other/historical names associated with this locality:
Anderson Claims; Blue Star; NBMG Sample Sites 2863, 2864
Deposit: Discovery year: wwi shafts on top of hill along parallel nw-striking veins associated with fissure-filling vein systems possibly along- joint sets. Copper minerals and uranium occur along strike of veins. Zone of strongest cu-u mineralization was reported to be 300-400 ft west of main open pit, where a remnant of auld lang syne sediments is preserved As a roof pendant. The zones of strongest mineralization are those which are the most calcareous. Three samples from the nure program assayed between 144 and 334 ppm u; these samples came from calcareous sediments. Sample 2864 is from the contact-type deposit of tactite . Uranium is spotty with high-grade individual pieces, but mining would lower ore grade below economic levels
Deposit type: W skarn
Development: Originally developed for copper, but proved to be of lo W economic value. Mined intermittently until 1961. Recently staked by pbc mining co. (1984) . Tungsten mineralization was discovered about 1917 and the property was controlled by gold, silver,and tungsten, inc, the owner of the nightingale mine. In 1944 it was acquired by rare metals corp.and during 1944-1955, several thousand tons of ore were mined and concentrated at the toulon mill, most of which was mined from an open pit
Geology: Ore in south edge of small roof pendant in granodiorite, As lenses composed of garnet and epidote associated with quartz and limonite. Scheelite occurs As disseminated crystals up to 2 1/2 inches, with malachite staining. Two bodies of tactite in the steeply dipping calcsilicate hornfels, one 250 feet long with max width of 30 feet at the center dividing into layers that lens out. Scheelite is unevenly distributed some bands 1-2 feet wide with more than 1% wo3, average content is 4% wo4. The second tactite body, 220 feet long, average 20 feet wide, with low wo3 content.
Ore(s): Calcareous Rocks Near Intrusion.
