Location and accuracy	This prospect is about two miles from Kukak Bay in an unnamed drainage that enters the northwest side of the bay. The prospect is in sec. 27, T. 21 S., R. 31 W., of the Seward Meridian. This is location 1 of MacKevett and Holloway (1977). The location is accurate.

Geologic setting

Geologic description Martin (1920) described a copper prospect at Kukak Bay on which some work was done about the time of World War I. The 'ore' reportedly assayed 4 to 6 percent copper, $1.50 to $4.60 in gold, and as much as 36 ounces of silver per ton. A shaft (winze) was sunk 10 feet from a point 40 feet from the portal of a tunnel 180 feet long (Cobb, 1980). Church, Riehle, and Goldfarb (1993) describe the Kukak Bay prospect as chalcopyrite-bearing quartz veins and breccias in a Tertiary pluton.
