The Killarney is a gold mine located in Alaska.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.
Mine Info
Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Production): Production Notes = About 180 tons of ore was mined from the Killarney workings during 1932; the ore was processed at the Saint (St.) Paul mill (Stewart, 1933, p. 141).
Comment (Deposit): Model Name = Schist-hosted gold-quartz vein
Comment (Geology): Geologic Description = About 180 tons of gold was produced from the Killarney mine, which consists of fractured and re-cemented gold-bearing quartz veins in micaceous schist (Chapman and Foster, 1969, p. D18; Stewart, 1933, p. 140-141). The veins are oriented N. 5 E., 75 W. and are intersected at intervals by faults that trend at a shallow angle to the strike and dip of the veins (Stewart, 1933, p. 141). Two types of quartz were observed in the vein (Stewart, 1933, p. 141). One type is low-grade ore, has a sugary texture, and is unfractured. The other is somewhat translucent, grayish quartz that has been fractured into segments from one-quarter inch to one-half inch in length that were was subsequently recemented. In the second type of quartz, free gold is visible in particles as large as a pinhead. Workings consisted of a 94-foot shaft with three drifts (Stewart, 1933, p. 140-141).
Comment (Workings): Workings / Exploration = In January of 1932, a vertical shaft was started that eventually reached a depth of 94 feet by 1933 (Stewart, 1933, p. 140). At the 90-foot level, drifts were extended both north and south along the vein. The north drift was driven a distance of about 60 feet from the shaft where it encountered a fault. The south drift was driven for about 165 feet from the shaft. Another drift at the 30-foot level was driven northward toward the fault (Stewart, 1933, p. 140-141).
