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 Red Wing prospect is about 0.7 mile east of the mouth of Spruce Creek at the head of Windham Bay; it is about 0.4 mile northwest of the center of section 25, T. 49 S., R. 75 E. The location is accurate.
Geology: The Red Wing 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 a caved adit at least 75 feet long that extends to a stope that has been mined vertically for less than 10 feet (Kimble and others, 1984). There is also the remains of a small mill on the property. The deposit consists of several thin quartz veins that contain pyrite, pyrrhotite, sphalerite, galena, and chalcopyrite. Kimble and others (1984) sampled veins in the old stope. A channel sample across a 1-foot-long quartz vein contained 30 parts per million (ppm) silver and 0.70 ppm 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: An adit at least 75 feet long and a small stope.
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.
Production: The presence of a small stope and a mill on the property suggests that there was production of a small amount of gold.
