Point Location Description: Occurrence
Location Method: Conversion from MDI
Access Description: The occurrence is located approximately 12 km south-southeast of the town of Dryden on the northwest and southeast shores of Mile Lake. The occurrence is located approximately 12 km south-southeast of the town of Dryden on the northwest and southeast shores of Mile Lake . The deposit may be reached by boat from Wabigoon Lake through Contact Bay via Threefork Creek. Boat launches are located in numerous places on Wabigoon Lake. Highway 502, which goes south from Dryden, passes just south of Contact Bay and Trap Lake which is south of Mile Lake. Roads lead to both bodies of water from the highway.
1924: The occurrences were discovered and test blocks were extracted from the southeast occurrence, presumably by the Wabigoon Soapstone Company, Ltd. (Wright in Wilson 1926; Satterly 1943). 1970: Test pits were sunk on the northwest occurrence during copper/nickel exploration (Storey 1986).

Geological Age: Archean
Dec 07, 2005 (R Degagne) - The area was mapped by Satterly (1943). The Mile Lake-Trap Lake area is underlain by a northeast-trending mafic to ultramafic body (4.2 km by 1.8 km in size) which intrudes metavolcanic rocks to the north and granitic rocks to the south. The granitic and mafic to ultramafic rocks are cut by a 100 m wide northwest-trending diabase dike.

Dec 07, 2005 (R Degagne) - Satterly notes that the mafic to ultramafic rocks are gabbro and harzburgite. The soapstone occurrences appear to be altered ultramafic components of the intrusive body. The Mile Lake occurrences are described by Satterly (1943), Storey (1986), and Kennedy and Sherlock (1989). Satterly (1943) suggested that the southeast occurrence was probably a highly altered, ultrabasic lens in the gabbro.

Dec 07, 2005 (R Degagne) - The soapstone is medium-grained and mottled greenish-grey and black. Storey (1986) noted joints 115/80 S and 355/90 spaced 0.6 m and more apart.TEST RESULTS:Specific Gravity: 2.85 (Southeast occurrence); Chemical Analysis: Si02-37.60, Ti02-0.11, Al203-6.25, Fe203-11.10, FeO--, MnO-0.09, MgO-26.90, CaO-4.62, Na20-0.0, K20-0.0, P205-0.01, CO2-6.26, S-0.01, H2O+- H20-- TOTAL- 92.95, LOI-12.90 2.

Geologist: R Degagne
Notes: The occurrence is exposed in one outcrop approximately 20 m from the shore of the lake. The outcrop is roughly 15 m by 15 m. Evidence of past work consists of one small pit from which material has been removed. Some remnant pieces of the soapstone lie about the site; some of them have sawn surfaces. Several caved-in and overgrown trenches in the clay overburden were observed between the shore and the outcrop. Carving Tests: A sample from the southeast occurrence was submitted to Stone Studio Siku Inc. of Parry Sound, Ontario It was determined to be the most suitable carving material of the northwestern Ontario soapstone samples tested, although still somewhat hard for the carving techniques employed by the artist (B. Krummrei, Stone Studio Siku, Inc., personal communication, 1988). A relief carving produced from the material is the frontispiece of this report. The stone has an attractive mottled appearance and adapts well to the various finishes applied including polished, honed, sandblasted and hand engraved.
