Samples of mica almost certainly from the Ardarie deposit located on the north side of Loch Sunart 630 yards north 20 degrees east of Ardarie, at an altitude of 700 feet, one-third of a mile from Ardarie Farm and approximately four miles west of Strontian, Argyllshire. British Geological Survey Petrology Collection sample number MC 7437. The mica deposit is a quartz-rich pegmatite vein which runs in a general north and south direction and can be traced along the strike for 30 yards. Books of mica up to twelve inches in diameter have been found closely crowded together resulting in mutual interference, bending and distortion of a large percentage of the mica. Because of this it was thought that most material would have been suitable only for grinding or pulping rather than higher quality sheet mica.
