Jul 12, 2012 (A Wilson) - Visually estimated grades on hand samples of 20-35% are present. These visual estimates correlate well with the binocular microscope point-count testing of the coarser grain size fraction (-20 to +42 mesh). The main mineralogy of the samples consists of orange-red, often rounded garnets, black hornblende and pyroxene, and white to clear plagioclase, quartz and possibly K-feldspar. Biotite is uncommon and magnetite is present in trace amounts. Pale green-yellow olivine is present in one sample. The calculated garnet content of the three Mattawan P property samples ranges from 14.6% to 21.4%.
