Point Location Description: General
Location Method: Conversion from MDI
Access Description: The quarry is located on the eastern part of Cooke Point, on the southern shore of Lake Nipigon, west of the Virgin Islands. The point can be reached by boat from launches in the village of Macdiaramid and in South Bay.
1866 The deposit was identified and described as early as 1866 (Bell, 1869; Royal Commission Report, 1890; ODM, Vol. 17, 1908). 1930 James W. Lawrence and Robin Boyle of Toronto staked 26 claims to cover the deposit and shoreline. 1931 The Lake Nipigon Marble Corporation, Ltd. did work at the site that included the removal of test blocks and the construction of buildings. A storehouse, a bunkhouse, and a dining hall were erected at the site to accommodate 12 men. 1932 to 1954 Because of promising test results, Lawrence and Boyle attempted to develop the site as a source of ornamental stone. This failed due to the lack of a market. With the war in the 1940s, the two gentlemen began examining other possible uses for the marble. The stone was tested as a source of magnesium and as a flux material. The magnesium content was not high enough to support a magnesium market and the silica content was to high for use as a flux. In the 1950s the claims lapsed and no activity has been reported since that time. 1994 The quarry is currently unstaked. COMMENTS: The location of this quarry essentially eliminates any possibility of future development. The quarry is inaccessible by road and located on Lake Nipigon which is classed as a Forest Reserve. The stone is attractive, however, exposures observed by the author displayed thin beds and a thick cap of diabase which would make extraction difficult.
Province: Southern
Subprovince: Nipigon Basin
Formation Group: Sibley Group
Geological Age: Paleoproterozoic
Dec 07, 2005 (B Schnieders) - The quarry is located within calcareous sediments of the Proterozoic Sibley group. This unit is exposed at the base of a keweenawan diabase sill for about 1.6 km olong the lake shore, and rises 6 m above the water level. The unit is dolomitic limestone that is thinly bedded and gently folded. The quarry site is currently overgrown and is recognized by the presence of old railway steel and pieces of equipment in the water (Hinz et al. 1994 OFR 5890).

May 06, 2011 (N Bennett) - MINERALOGY:Coleman and Moore (1908) described the mineralogy of the marble: Thin sections show fine-grained, closely interlocking calcite, with small amounts of some turbid substance. JOINTING: Overall the unit is thinly bedded and has many vertical fractures. COLOUR: The stone is white or pale green in colour. There are some areas with a reddish tint. TEXTURE: The stone is very fine grained. PHYSICAL PROPERTIES: Weathering test: Asample was immersed in sodium sulphate for 24 hours, taken out of the solution, and heated for 24 hours. This cycle was done four consecutive times without sign of cracking or disintegration. Absorption test: A sample was dried for 24 hours then immersed in corn oil for24 hours, after which the sample was removed and weighed (absorption 0.98%) Compression test: Three samples (2 inch cubes) had lead weights applied at right angles to the face. These are the results: SAMPLE 1: 5750 Load per square inch. SAMPLE 2: 4250 Load per square inch. SAMPLE 3: 5882 Load per square inch. Average: 5294 Load per square inch. Tests performed by J.T. Donald and Co., Montreal (1931).
