|Location and accuracy||The Home Lode (Cobb, 1980 [OFR 80-363]) prospect is at an elevation of about 2500 feet on the south side of the valley of Crevice Creek. It is about 0.1 mile southeast of the center of section 24, T. 15 S., R. 17 W., Fairbanks Meridian. The location is approximate; it probably is accurate within 0.2 mile. The prospect is location 23 of Cobb (1972 [MF 366]), 51a of Bundtzen, Smith, and Tosdal (1976), 227 of Hawley and Associates (1978), 63a of Bundtzen (1981), and 73 of Thornsberry, McKee, and Salisbury (1984).|
Geologic descriptionThe country rocks in the area of the Home Lode prospect are micaceous schist and quartzite of the upper Precambrian Birch Creek Schist (Bundtzen, 1981) The schist strikes NE and dips W (Thornsberry, McKee, and Salisbury, 1984). The deposit consists of a brecciated quartz vein that is cemented by a second generation of quartz containing small amounts of stibnite (Wells, 1933, p. 377). The quartz is stained with iron oxides and with a yellow secondary antimony mineral, probably stibiconite. No assays have been made public.
|Geologic map unit||(-150.754387336955, 63.5990981500027)|
|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||Oxidation of iron and antimony minerals.|
|Workings or exploration||The Home Lode was discovered and staked by William Julian, a miner who prospected in the Caribou Creek area for many years. When the prospect was visited by Wells (1933) in 1931, the pits were sloughed. The prospect may not have been visited since then.|
|Indication of production||None|
Additional commentsThe prospect is in Denali National Park and Preserve.
