Sep 05, 2013 (A Wilson) - The marble unit trends 020 and dips steeply to the west. Gneissosity is indicated by bands of different composition, by trains of inclusions and disseminated silicate minerals. Rusty amphibolitic inclusions are commonly observed in the southwestern part of the stripped area. Two main types of marble were mapped: a pure, coarse-grained variety and an impure type with disseminated silicate minerals. The marble is described as being very white and coarse grained and the inclusions are smaller and more evenly dispersed throughout the body of the marble. The predominant inclusions throughout the stripped area is a white augite-bearing granite, with minor amphibolite, quartzite, diopsidic granite and biotite syenite inclusions

Sep 05, 2013 (A Wilson) - The material was originally designated as being suitable as a filler in rubber carpet backing material. A variety of non-carbonate minerals disseminated in the marble include quartz, scapolite, phlogopite, plagioclase, potassium feldspar, clinopyroxene, tremolite, magnetite, titanite, pyrite, apatite and graphite. Three samples were collected for beneficiation studies by the OGS. Flotation of sample “impure S” yielded a product containing 91.6% calcite with a recovery of 92.7% while a production containing 96.8% calcite at a recover of 89.7% was made from sample L.
