The site is in Denali National Park and Preserve.
Location: The Chlorine prospect is on a patented claim at an elevation of about 3600 feet on the south end of hill 3835, about two miles east of Wickersham Dome. It is in the NE1/4 SW1/4 section 4, T. 16 S., R. 17 W., Fairbanks Meridian. The location is at the approximate center of the east endline of the Chlorine claim (Hawley and Associates, 1978). The location is accurate within 500 feet. There is no public description of the deposit on the Chlorine claim. This record describes a deposit on the Saddle claim, which apparently adjoins the Chlorine claim on the south (Thornsberry, McKee, and Salisbury, 1984, no. 57; Bundtzen, Smith, and Tosdal, 1976, no. 39; Bundtzen, 1981, no. 47).
Geology: The country rocks in the area of this site are mainly metafelsite and marble of the lower Paleozoic Spruce Creek sequence. The rocks strike east-northeast and are cut by a Tertiary basaltic dike (Bundtzen, 1981; Thornsberry, McKee, and Salisbury, 1984, fig. K-2). No mineral deposit data have been published on the Chlorine claim. In this record, information about the Saddle prospect is assumed to apply generally to the Chlorine and Grizzly prospects. The deposit at the Saddle prospect is a sparsely mineralized quartzose shear zone about 8 feet wide exposed for about 100 feet. Pyrite- and arsenopyrite-bearing samples of the zone assayed up to 0.01 ounce of gold per ton, 0.09 ounce of silver per ton, and 5720 ppm arsenic (Thorsberry, McKee, and Salisbury, 1984, occurrence 57).
Workings: The Chlorine deposit probably was prospected by discovery pits. Prospecting on the Saddle claim was limited to trenches, some of which did not penetrate the overburden.
Age: Uncertain, probably Eocene (see record MM091).
Alteration: Silicification of metafelsite.
Commodities (Major) - Au; (Minor) - Ag, As
Development Status: None
Deposit Model: Low-sulfide Au-quartz vein (Cox and Singer, 1986; model 36a).
