Location and accuracy The Lucky Tuesday prospect is at an elevation of about 2500 feet, about 1/2 mile north of the top of Busia Mountain. It is about 4000 feet east of the center of section 23, T. 16 S., R. 18 W., Fairbanks Meridian. The location is probably accurate within 500 feet. The prospect is number 7 of Bundtzen, Smith, and Tosdal (1976) and Bundtzen (1981), 18 of MacKevett and Holloway (1977), KX 66-105 of Hawley and Associates (1978), and 22 of Thornsberry, McKee, and Salisbury (1984).

Geologic setting

Geologic description

The country rock at the Lucky Tuesday prospect is weakly ironstained quartz-sericite schist of the Birch Creek Schist (T. K. Hinderman in Thornsberry, McKee, Salisbury, 1984, v. 2, occurrence 22). The deposit consists of poorly explosed quartz-stibnite veins up to about 3 feet thick. The veins apparently strike E-W to about N 30 E. Grab samples from high-grade ore piles and a sloughed pit contain as much as 54.2 percent antimony. Small amounts of gold and silver are present; samples assay up to 0.07 ounce of gold per ton and 0.21 ounce of silver per ton. Lead is abundant enough in one sample (0.31 percent) to be present as galena or a lead sulfosalt.

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 MM091).
Alteration of deposit Weak iron staining.

Production and reserves

Workings or exploration The prospect was developed by one pit, probably excavated by Jim Fuksa, who owned two Lucky Tuesday claims. The pit is sloughed.
Indication of production Undetermined

Additional comments

The prospect is in Denali National Park and Preserve.
