Nov 06, 2013 (A Wilson) - A graphite gneiss has been traced from a possible width of 200 ft in an east-west direction. It is bounded to the east and west by coarse pegmatite. The gneiss trends N75W with a dip of 45º S on the hill south of the valley to N5W with a vertical dip on the north slope of the valley. The gneiss is metaluminous to marginally peraluminous alaskite with augen structure and relict augen structure.

Nov 06, 2013 (A Wilson) - The graphite flakes on the south side of the valley range from 1/20 to ¼ of an inch in diameter and form, on the average, 8-10% of the rock. To the north, the percentage of graphite is lower and it is doubtful from grab samples if it would average 5% graphite.
