It was situated on the north side of Loch Nevis, 1100 yards south 12 degrees east of the summit of Sgurr Coire nan Gobhar, 7.5 miles due east of Mallaig. The deposit was the most extensive and most valuable source of mica known in the Western Highlands. Books of mica up to 2 feet in diameter and crystals a foot or more were common. The mica is excellent quality and is graded as a good fair-stained ruby. Mica-bearing pegmatites are common throughout the Highlands, however, commercial grade and quality are comparatively rare. During the Second World War mica deposits of economic potential were looked at in the Strathgarve district of eastern Rossshire and western Invernessshire and north-west Argyll, along a north-south belt extending from Loch Sunart across Loch Shiel and Loch Nevis into Knoydart.
