Dec 07, 2005 (C Papertzian) - The geology is described by Guillet, 1964, Industrial Mineral Report # 12: 'The two veins are exposed at the water's edge near the tip of the southernmost peninsula on the north side of the lake. They are about 200 feet apart and have parallel strikes of N. 50 degrees West. The country rock is a banded cram, grey, or buff Grenville marble with quartzitic interbeds, trending northeasterly to easterly with steep northerly dip. Jointing is the Grenville rocks is closely spaced in a direction parallel to the veins. Strong hematite staining is locally developed in areas of intense jointing. ' The east vein material has been described as 'being mainly fluorspar and barite.' The west vein is a calcite-fluorite vein.

Geologist: C Papertzian
Notes: This deposit consists of an east and west vein system. They are very narrow. The east vein material is 6 to 18 inches in width, trending north 40 degrees west. The dimensions of the excavation is 90 feet long, 3 to 5 feet wide and 1 to 18 feet deep. An old timbered shaft was located in the cut approximately 40 feet north of the lake. The West vein material measures 4 to 18 inches wide. The excavation measures 40 feet long, 3 feet wide and 5 feet deep. This property was visited on March 18, 2004. There is no evidence of any workings remaining. They have probably all been filled in to accomodate the construction of cottages. The shaft on the west vein is covered by a tennis court. At one time 15 men were employed the mine site. Excessive water was a constant problem underground (personal communication Mrs. G. Kramp). Production from the Coe mine was approximately 114 tons.
