Location and accuracy This occurrence is at an elevation of about 3250 feet, on the crest of a ridge approximately one mile southwest of the junction of Canyon Creek and Moonlight Creek. It is approximately at the midpoint of the section line between sections 21 and 28, T. 14 S., R. 15 W., Fairbanks Meridian. The site coincides with number 64 of Bundtzen, Smith, and Tosdal (1976), 102 of Thornsberry, McKee, and Salisbury (1984), and 25 of MacKevett and Holloway (1977).

Geologic setting

Geologic description

This occurrence consists of a stibnite-quartz gash vein in Birch Creek Schist, near a contact with the Keevy Peak Formation (Bundtzen, 1981). The vein is roughly parallel to the schistosity of the country rocks. It is less than a foot thick and is exposed in outcrop for about 6 feet. Assays of the vein
show a trace of gold, as much as 0.33 ounce of silver per ton, 65 percent antimony, and 0.74 percent lead, and detectable copper, lead, and zinc (Bundtzen, Smith, and Tosdal, 1976).

Mineral deposit model Simple stibnite deposit (Cox and Singer, 1986; model 27d).
Mineral deposit model number 27d
Age of mineralization The deposit is assumed to be Eocene (see record DN091).

Production and reserves

Workings or exploration The deposit was discovered during mapping of the Kantishna district by the Alaska Division of Geological & Geophysical Surveys (Bundtzen, Smith, and Tosdal, 1976). There are no workings.
Indication of production None
