|Location and accuracy||Approximate location is about 2 mi (3.2 km) southeast of Mt. Dutton, near Belkofski Bay. Anomaly no. 71 of Christie (1974) and no. 11 of MacKevett and Holloway (1977, p. 9).|
Geologic descriptionChristie (1974) described a color anomaly and associated gossan developed in hornfelsed andesite and dacite east of a contact with a fresh, medium-grained, unpyritized quartz diorite pluton. Gossan forms an oval, roughly 2,000 by 1,200 ft (1,500 by 900 m), but it is not fully delineated. Within the color anomaly, there are several thin breccia zones which are highly leached. Color anomaly is due to the weathering of pyrite, which is disseminated or localized in fractures in concentrations up to 8 percent. Northwest of the gossan, very recent volcanic debris and young flows from Mt. Dutton cover a hidden gossan as evidenced by bright orange seeps and strong iron-oxide staining in creek.

|Mineral deposit model||Epithermal gold vein|
|Mineral deposit model number||25|
|Age of mineralization||Pliocene or younger|
|Alteration of deposit||Alteration is absent to weakly propylitic as evidenced by the presence of epidote and chlorite.|
|Workings or exploration||Brief reconnaissance geologic mapping and collection of a few soil and silt samples reported by Christie (1974). Gold, silver, zinc, copper, and molybdenum were at background levels.|
|Indication of production||None|
Additional commentsSampling probably not adequate to evaluate for epithermal gold vein mineralization.
