|Location and accuracy||This occurrence is at an elevation of about 3,800 feet south of upper Blind Creek, a tributary of the West Fork Chulitna River. It is in the NE1/4 of sec. 5, T. 20 S., R. 11 W., of the Fairbanks Meridian. Accuracy is to within 1,000 feet. The site is shown in Hawley and Clark (1968), and Hawley and Clark (1974).|
Geologic descriptionThe country rocks in the area of this occurrence are Triassic sedimentary strata that have been strongly faulted along a strand of the Blind Creek fault. The fault zone is up to 200 feet wide and approximately 3000 feet long; it is locally pyritized and limonite stained. The deposit consists of quartz-pyrite veins. The quartz is colloform in places. Surface samples from a quartz vein contained 0.06 ppm to 0.30 ppm gold and 0.5 to 1.5 ppm silver (Hawley and Clark, 1968).

|Mineral deposit model number||22c, 25a|
|Alteration of deposit||Pyritization; iron-staining.|
|Workings or exploration||Surface samples only. Surface samples from a quartz vein contained 0.06 ppm to 0.30 ppm gold and 0.5 to 1.5 ppm silver (Hawley and Clark, 1968).|
|Indication of production||None|
Additional commentsThis deposit is similar in some ways to the Bunkhouse and Lupin deposits (HE039 and HE038).
