NTS Grid: 52F03SW
Point Location Description: Occurrence
Location Method: Conversion from MDI
Access Description: The occurrence lies along the western shore of the southern bay of Sucan Lake, 55 km north of the town of Fort Frances. The occurrence is accessible from Sucan Lake. Sucan Lake may be reached from Straw Lake, which is reached by portage from Thompson Bay of Pipestone Lake. Pipestone Lake is accessible by boat via Burditt lake from the north end of Highway 615, 45 km northwest of Fort Frances.
There is no record of exploratory work for soapstone at this location. Diamond drilling was carried out in the vicinity of the occurrence in 1969 by the Canadian Nickel Company Limited during copper exploration. (Resident Geologist's Files, MNDM, Kenora).

Dec 07, 2005 (R Degagne) - The area was mapped by Thomson (1934) and Edwards (1983b). The occurrence was described by Storey (in press). Edwards notes that the area south of Sucan Lake is underlain by a roughly crescent-shaped stock-like composite mafic to ultramafic body which intrudes mafic flows and felsic tuff and lapilli tuff. The occurrence consists of altered (talcose, serpentinized) peridotite within this body.

Dec 07, 2005 (R Degagne) - STONE DESCRIPTION: Storey (in press) notes that the talcose rock is blue-grey in colour, soft and fine grained with no obvious foliation. The rock varies in hardness. It contains ankerite which results in a rusty weathered surface. X-ray diffraction mineral analysis, reported by Storey, indicates that the rock consists primarily of talc with chlorite and dolomite and minor magnetite and amphibole.
