Jan 13, 2016 (Therese Pettigrew) - Carbonate-diopside rock is at the south contact of sedimentary rock and the north contact of the -ipper mafic rock unit. This rock is khaki green on weathered surface and contains coarsely crystalline green, brown and white minerals thought to be diopside, andalusite or vesuviante and calcite respectively. Calcite occurs in patches, lenses and veins. Black, zoned tourmaline, 1.0 to 1.5 cm long is an accessory mineral. Carbonate-diopside unit varies in outcrop thickness from 1 to 20 m. The south part of this unit is more chlorite-rich, schistose and free of cross-cutting calcite veinlets whereas the north part contains gently folded bands of diopside and andalusite or vesuvianite with up to 5% carbonate occurring as cross-cutting veinlets, dolomitic to calcitic layers and feathery patches along layering.

Jan 13, 2016 (Therese Pettigrew) - Disseminated pyrite and blebs of molybdenum. No assays (M2614). Molybdenite is the predominant sulphide at the north part of the carbonate-diopside unit and occurs as disseminated blebs in andalusite or vesuvianite or as platey layers along the contact between diopside and andalusite or vesuvianite. In both cases calcite is associated with the sulphide (AFRI 42C12NW0039).
