|Location and accuracy||Approximate location is given as 2 to 3 mi (3.2 to 5 km) southeast of site of village of Morzhovoi at headwaters of creek flowing north into Traders Cove. Anomaly no. 51 of Christie (1974) and no. 5 of MacKevett and Holloway (1977, p. 11).|
Geologic descriptionChristie (1974) briefly examined an oval color anomaly (gossan) 8,000 by 6,000 ft (2.4 by 1.8 km) in size developed within volcanic and plutonic rocks. Pyrite is disseminated within discrete 50 to 200 ft (15 to 60 m) wide zones in bleached volcanic rocks at the outer margin of the gossan. Pyrite may be more pervasive in rocks underlying the drift covered valley floor, an area covering 1.2 by 0.9 km. A diorite pluton intrudes the volcanic rocks and the sulfide zone is localized within and adjacent to pluton. Minor amounts of sulfides are localized in fractures and quartz veins fill some fractures in a stockwork. Minor breccia is found in float and is characterized by tourmaline rosettes developed in proximity to pyrite grains.

|Mineral deposit model||Epithermal gold vein|
|Mineral deposit model number||25|
|Age of mineralization||Miocene or younger|
|Alteration of deposit||Propylitic alteration is developed in the diorite as evidenced by the presence of chlorite and epidote. Hydrothermal feldspar and clay is mentioned as present within the color anomaly but not otherwise described.|
|Workings or exploration||Brief reconnaissance geologic mapping and a few silt samples collected by Christie (1974). Two of eight samples had 0.02 ppm gold; it does not appear occurrence is adequately examined for epithermal gold vein potential.|
|Indication of production||None|
Additional commentsQuartz veining is briefly mentioned which supports the potential for epithermal gold veins.
