Jan 12, 2012 (A Wilson) - A rusty gossan approximately 90m wide along the north side of Highway 17 marks the main graphitic horizon in this claim group. The mineralized zone trends northwesterly and dips at about 4O° to the northeast.

Jan 12, 2012 (A Wilson) - Disseminated flake graphite visually estimated to range between 2% and 6%, occurs in thinly laminated graphite-quartz-plagioclase-biotite-sillimanite metapelite. This same graphitic horizon may be traceable for up to 500m in a northerly direction, as similar mineralization was observed in outcrop along this trend. Flake size varies from 1mm to 2mm in the cleaner sandy facies and is up to 6mm in size in the more biotite-feldspar-quartz facies. Thin quartz-feldspar segregations commonly have coarse flake and composite flake (smears) developed along mineral segregation interfaces. There are well mineralized sections up to 8 m thick interbedded with thin (1m to 3m) relatively barren, gneisses exposed along the highway section. Graphite analyses from the trenches returned values of 5.75%, 4.98% and 5.80% graphite. The best grades of pulverized ore from these trenches are found on the 35m, 65m and 100m sizes {3.91%, 6.33% and 4.52%, respectively). The grades of most trenches peak at the 65m size.
