Oct 30, 2013 (A Wilson) - Graphite is found within medium- to coarse-grained, gneissic, silicic marble containing thinly intercalated units of amphibole-rich metasedimentary rocks. Some areas of light to dark green skarn also have been observed in the area. The graphitic units are typically 4-7 feet in width.

Oct 31, 2013 (A Wilson) - Flake graphite has been observed in the gneissic rock. A representative grab sample from the property by J. Thomson contained 5.3% graphite. To the north of this showing a 5 m long adit was driven into the side of a ridge to expose a zone of disseminated graphite in a "leached gneiss" host rock. A chip sample taken by Thompson across the zone reportedly returned 6.4% graphite over 3.7 m. The adit was reportedly on the south half of Lot 24 or 25 concession 11. The graphite in the adit reportedly occurred over a true width of 3.6 - 4 m. Graphitic mineralization on the Herschel property is present in two distinct styles. The economically most significant is fine- to medium-flake disseminated graphite hosted in fine-grained, quartzo-feldspathic paragneisses. Assays in these units range from less than 1% Cg to 10.56% Cg. Distribution of grade is erratic and may vary by an order-of-magnitude within a single pit; however, semi-continuous horizons in excess of 200 m in length can be inferred. The second style of mineralization consists of medium-coarse graphite flake hosted in calcite marbles. This mineralization is located in the northernmost property area, and appears to be restricted to a single, laterally continuous marble over at least 400 m. Within this unit, mineralization is discontinuous, and all assays are less than 2%Cg. Grab samples collected by the ODM in 1943 returned 5.3% Cg near the main pit and a chip sample taken across a true width in the adit returned 6.4% Cg.
