Lithology Comments

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.

Mineralization Comments

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.
