There may be patented claims or private holdings on this and other properties at the head of Windham Bay but most of the area is part of the Chuck River Wilderness Area which is closed to prospecting and mining.
Location: The Jenny Reed prospect is about 0.7 mile northeast of the mouth of Spruce Creek at the head of Windham Bay. It is about 0.7 mile northwest of the center of section 25, T. 49 S., R. 75 E.
Geology: The Jenny Reed prospect is one of many auriferous lodes at the head of Windham Bay, most of which have been known since at least 1904 (Wright and Wright, 1906; Kimble and others, 1984). The prospect consists of two adits: the longest is about 165 feet long and the other is about 20 feet long (Kimble and others, 1984). The host rocks are muscovite schist and phyllite of Cretaceous age (Brew and Grybeck, 1984). The deposit trends along the long adit (Kimble and others, 1984; figure 32); it consists of a quartz-stringer zone with disseminated pyrite, sphalerite, and chalcopyrite. The zone is parallel to the foliation of the schist and phyllite. The richest sample collected by Kimble and others (1984) was a 7.4-foot-long channel sample that contained 1.0 part per million gold. The deposits at the nearby Marty prospect (SD041) and the Sumdum Chief Mine (SD028) have been dated at about 55 million years (Goldfarb and others, 1997). This prospect is geologically similar and probably of the same age. Goldfarb and others (1997) also propose that most gold-quartz vein deposits along the Juneau Gold Belt such as this one were formed from fluids generated by Cretaceous metamorphism and then forced to the site of deposition by the emplacement of the Coast Range Batholith.
Workings: The workings consist of two adits, one about 165 feet long and the other about 20 feet long. There was some exploration in the area in the 1970's but the workings date from before WW I.
Age: The deposits at the nearby Marty prospect (SD041) and the Sumdum Chief Mine (SD028) have been dated at about 55 million years (Goldfarb and others, 1997). This prospect is geologically similar and probably of the same age.
