Oct 29, 2013 (C Papertzian) - The property is located within an inlier of Grenville rocks surrounded by Paleozoic sandstone. Graphite occurs in silicified bands of Grenville marble which strike N70E and dip 50-60º NW. The marble is intruded by pegmatite and enclosed by diopside-pyroxenite to diopside-calcite bearing feldspathic gneisses. The main ore zone has been traced along strike for approximately 400 feet. The ore zone lies on the drag folded north limb of an anticline. The Z-shaped drag-fold pitches vertically. Drilling on the down-plunge extension of the main graphite zone has indicated that the mineralization extends to a vertical depth of at least 300 feet. However, the thickness and grade are somewhat less than at surface, where up to 40 feet of 15% graphite was reported from the old workings. The strike length of the zone would also appear to shorten slightly with increasing depth. On the basis of the present drill results, it is provisionally estimated that perhaps 50,000 tons grading in the region of 7% graphite might remain in the deposit below the mined-out portion, to the 300 ft. level. This mineralization is divided between up to four separate zones, which would tend to make mining difficult and expensive.

Oct 29, 2013 (A Wilson) - The graphite ore occurs in three narrow bands separated by narrow graphite-poor marble bands. The maximum ore width on the crest of the drag fold was 40 feet. The ore grade was estimated to be15-25% C in 1920. The graphite occurs predominantly as equidimensional flake, averaging between 0.5 and 1.0 mm in diameter and as small bodies of “needle flake” wherein the length of each needle may be 5 to 6 times its width. The mineralization is divided among 4 zones. Graphite-rich zones containing up to 20% graphite are separated by medium- to low-grade marble bands. Grab samples collected from the northeast end of Pit 1 by the OGS in 1989 returned values of 8.14% and 13.85 % graphitic carbon. Graphite at the No 1 pit is described as lensey, with bulges forming two main zones. The east lens has a length of 250 feet and a width of approximately 7.5 feet. To the west, the zone narrows to 4 feet for a distance of 70 feet and then bulges out to 8 ft for a distance of 90 feet. At the crest of the fold the graphite zone reached a thickness of 40 feet. Two graphite zones reportedly occur at the base of the 250 foot shaft. The zones are 1 and 2 feet in width and are separated by 15 feet of marble. The grade of the limestone and the graphitic zones averaged 7.1% C over 18 feet.
