Dec 05, 2011 (A Wilson) - Fairly pure calcitic marble, with less than 5% of disseminated silicate minerals occurs as narrow bands interlayered with the predominate impure limestone. One wider band of clean limestone (3-4 m) can be traced northward from the main pit for approximately 60 m. When almost free of disseminated non-carbonate minerals, the rock is massive, equigranular and commonly weathers and disintegrates to a buff-coloured sand. This is most noticeable adjacent to inclusions of meta-diabase, and in the cores of isoclinal folds. A variety of inclusions occur within the marble band. Individual inclusions range up to 30 m long and 10 m wide. Most of these inclusions are lozenge-shaped and many of the smaller inclusions are tabular and contorted. The inclusions are typically mafic gneiss, scapolitic gneiss, granite and syenite.

Dec 05, 2011 (A Wilson) - Calcite occurs as interlocking grains ranging from 2-5mm in size. Marmont and Johnston observed 1-2% disseminated flake graphite within a 3-4 m wide band of pure marble. Channel samples collected by the OGS from the stripped area returned the following analyses: 86 CCM 0385 -43.96% CaO, 5.306% MgO, 0.450% Fe2O3, 0.035% MnO, 696 ppm Sr, 46.68% carbonate CO2 with a neutralizing value of 91.67. 86 CCM 0386 -48.02% CaO, 0.93% MgO, 0.307% Fe2O3, 0.022% MnO, 1020 ppm Sr, 39.03% carbonate CO2 with a neutralizing value of 88.07. 86 CCM 0387 -49.98% CaO, 0.963% MgO, 0.307% Fe2O3, 0.018% MnO, 1480 ppm Sr, 40.60% carbonate CO2 with a neutralizing value of 91.65. 86 CCM 0388 -51.24% CaO, 1.607% MgO, 0.286% Fe2O3, 0.017% MnO, 1460 ppm Sr, 42.28% carbonate CO2 with a neutralizing value of 95.50.
