Location and accuracy The Water Level prospect, on a patented claim, is at an elevation of almost 2000 feet in the canyon of Eureka Creek, about one mile above its mouth. It is in the SE1/4 SE1/4 section 12, T. 16 S., R. 18 W, Fairbanks Meridian. The location is accurate within 500 feet. The prospect is number 21 of Hawley and Associates (1978), 32 of Bundtzen (1981), and 37 of Thornsberry, McKee, and Salisbury (1984).

Geologic setting

Geologic description

The country rock at the Water Level prospect is south-dipping quartzitic schist of the Birch Creek Schist (Thornsberry, McKee, and Salisbury, 1984, fig. K-2). The deposit consists of mineralized quartz-siderite veins. Davis (1923, p. 130) described a 3-foot-thick, galena-bearing vein that assayed 30 to 40 ounces of silver per ton. Bundtzen (1981, location 32) described a vein that strikes ENE and dips steeply to the NW. It is 3 to 6 feet thick, strongly sheared and oxidized, and contains galena, pyrite(?), cerussite, and limonite. Float near or at the prospect assayed up to about 77 ounces of silver per ton (Seraphim, 1962), and Hawley and Associates (1978) collected a soil sample that assayed about 0.1 ounce of gold per ton.

Mineral deposit model Polymetallic vein (Cox and Singer, 1986; model 22c).
Mineral deposit model number 22c
Age of mineralization The deposit is assumed to be Eocene (see record MM091).
Alteration of deposit Surface oxidation of iron and lead minerals.

Production and reserves

Workings or exploration Most of the work at the prospect appears to have been done before 1922 (Davis, 1923). Moneta-Porcupine prospected at and near the prospect in 1960, and the prospect was examined by Bundtzen (1981). Little work has been done since 1922.
Indication of production None

Additional comments

The prospect is in Denali National Park and Preserve.
