Structure: Intersecting High-And Low-Angle Faults Striking Nw And Sw, Exposed On Face Of The Open Pit; Shearing Parallel To Bedding

Alteration: Argillic, Bleaching, Silicification

Deposit: Skarn zone of which only minor remnants remain exposed along 3-5 benches. On the E and W sides. Tongues of the granite body extend into the limestone unit and are argillically altered, bleached, heavily iron-stained with limestone-hornfels along the contact. Skarn minerals include garnet, pyrite, bismuthinite (?), pyrrhotite, chalcopyrite, sphalerite, fluorite, calcite, and wollastonite. The iron-rich sulfides are altered to a greenish clayey material resembling nontronite. Western edge of skarn zone is more gossany; limonite-stained, and exhibits a greater degree of hydrothermal alteration with much slag-like material. A massive white quartz vein with abundant open spaces carrying oxidized pyrite grains and ghosts, cuts both the limestone and the skarn zone. Very fine tremolite crystals are intergrown in the limestone. Massive (up to several feet wide) veins/clots of crystalline calcite/siderite/manganosiderite occur in the limestone. Locally the limestone is silicified near and adjacent to the quartz veins. Workings east of the open pit near the saddle include another small rather deep and narrow open pit which excavated ore along the contact of the intrusive and the skarn zon

Deposit type: W skarn

Development: Southern-most workings of union carbide's property at tempiute. No production at time of examination in 1983. But development work, blasting, etc. Was bein continued.

Ore(s): Igneous Contact
