A sedimentary iron ore occurrence located in secs. 27, 34 & 35, T.9N., R.15½E. on the East slope of Chediski Ridge/Butte, between Lost Tank & Mountain Lion Canyons, about 3 miles down Canyon Creek from the Apache deposit. Discovered in 1895. The USGS MRDS database stated accuracy for this location is 500 meters.

Mineralization is an Fe deposit (Mineral occurrence model information: Model code: 241; USGS model code: 34a; BC deposit profile: F10; Deposit model name: Superior Fe [BC name is Lake Superior & Rapitan types iron-formation]) near the top of the silicified middle member of the Mescal Limestone (Neoproterozoic quartzite, shale, sandstone, limestone and chert of the Mescal Limestone), and is overlain by the Chadiski Sandstone. The ore body has a depth-to-top of 500 meters with a minimum of 300 meters, width of 18 meters, length of 5,500 meters. It is stratiform & tabular. The primary mode of origin was sedimentation. Primary ore control was bedding. Wallrock alteration is silicification. Hematite ore occurs in tabular, irregular masses with silicification as an alteration product. The hematite zone is near the boundary between the white Chediski sandstone of the Troy Formation and the Mescal Limestone, just below a silicified algal zone. The ore ranges from nearly pure, red to bluish-black hematite with some specularite to beds that are interlayered and mixed with chert, jasperoid, sandstone, and shale. Iron mineralization appears to be related to the silicification in the Middle Member of the Mescal Limestone. Local rocks include Middle Proterozoic sedimentary rocks.

The average composition of the Chediski ore (plus 35 percent iron). exclusive of interbedded low-grade material and waste, is as follows: Fe: 48.92%; silica: 23.02%; P: 0.235%; S: 0.055%; lime: 1.01%; alumina: 2.26%; and, Mn: 0.10%.
