Resident Geologist District: Kenora
NTS Grid: 52F04SW
Point Location Description: Map in OFR5764 p. 92
Location Method: Data Compilation
Access Description: The occurrence is located in Claxton Township, 60 km northwest of the town of Fort Frances. It is located on the east side of Highway 71, approximately 4 km south of Caliper Lake Provincial Park . The occurrence is exposed on the side of Highway 71.
There is no recorded development of the occurrence, but it has probably been examined by carvers and prospectors (Storey 1986).
Province: Superior
Subprovince: Wabigoon
Geological Age: Archean
Dec 07, 2005 (R Degagne) - The geology of the area is shown on Map 2443 (Blackburn 1981). The occurrence has been described by Edwards (1982) and Storey (1986). The soapstone occurs within a small, elongate, ultramafic body, 5 km by 2 km, within the Sabaskong Batholith (Blackburn 1981). The soapstone unit is exposed for 70 m along the highway and has a width of approximately 3m. Storey (1986) noted that (quote)The talcose rock is found in rounded blobs 0.3 to 0.6 m long, often surrounded by a rim of chlorite-rich material 1 to 2 cm thick. The talc-bearing rocks show a wavy foliation trending northward and roughly vertical. The talc/soapstone is developed in amphibolitized peridotite (Edwards 1982).....The surrounding rocks include agmatitic dikes of granitoid and more mafic intrusive rocks (unquote).

Dec 07, 2005 (R Degagne) - The stone is fine grained, soft and light grey-green in colour; darker green in the more chlorite-rich areas. The presence of iron-carbonate is indicated by brown weathered surfaces. Samples submitted for X-ray diffraction analysis, reported by Storey (1986), indicate the rock is variable in composition. Talc, chlorite, and mica are the predominant minerals with lesser amphibole, calcite, quartz, feldspar and mica.
