Dec 07, 2005 (C Papertzian) - Mineral location [ poor ].
| Rock Type | Rank | Composition | Texture | Relationship | Paragneiss | 1 | Biotite-Quartz | Adjacent |
|---|---|---|---|---|
| Limestone | 2 | Calcitic | Crystalline | Host |
| Pegmatite | 3 | Syenitic | Adjacent |
May 04, 2011 (A Wilson) - The biotite paragneiss in the pit strikes N35°E and dips 20°SE. A small dump adjacent to the shaft reportedly consisted of fragments of pink and grey hybrid gneiss. The best mineralized material appears to have come from a lens of crystalline limestone containing coarse mica pyroxenite and granite-pegmatite. The metasediments are cut on the northeast face of the pit by a dike or sill of syenite.

May 04, 2011 (A Wilson) - The molybdenite was reportedly taken from the decomposed surface of the host rocks. A grab sample collected by the OGS in 1978 returned 945 ppm Mo, 33 ppm Cu and < 10 ppb Au (sample 78-K-1050)
