|Location and accuracy||Kimble and others (1984) sampled several altered zones along the west side of Tracy Arm west of its prominent elbow. The sample sites are centered about 0.4 mile south of the center of section 33, T. 45 S., R. 73 E.|
Geologic descriptionThis occurrence consists of several areas of weathered, iron-stained schist with disseminated pyrite and irregular quartz stringers that were sampled by Kimble and others (1984). Several claims were were reported in the area before 1900 and several others were staked between 1915 and 1920, but their locations are obscure. Kimble and others (1984) collected two samples across 40 feet of iron-stained schist; both contained 0.5 part per million silver and 20 ppm molybdenum.

|Mineral deposit model||Iron-stained schist with disseminated pyrite and barely anomalous silver and molybdenum.|
|Alteration of deposit||Iron staining, probably due to weathering of disseminated pyrite.|
|Workings or exploration||Only sampling by government engineers.|
|Indication of production||None|
Additional commentsThe occurrence is in the Tracy Arm-Fords Terror Wilderness Area which is closed to mineral exploration and mining.
