Lithology Comments

Nov 07, 2013 (C Papertzian) - The calcitic marble strikes N42ºE and dips 66ºNW and is interbedded with grey and white biotite-syenite gneiss. Graphite (flake and amorphous) occurs in a calcitic white-grey, medium-coarse grained micaceous (up to 15 % phlogopite) marble which has been intruded by syenite/monzonite and pegmatite.

Mineralization Comments

Nov 07, 2013 (A Wilson) - Graphite occurs as disseminated flakes and graphite seams. The graphite seams ranged up to 4 inches in thickness. The graphite reportedly ran as high as 76% Cg with an average of 50% Cg. The graphite was shipped in lump form. In the main pit, graphite occurs as disseminated flakes in both the marble and pegmatite. It also occurs as very fine grains in 1 cm or less shear zones in the marble.
