Resident Geologist District: Thunder Bay South
NTS Grid: 52B07SE
Point Location Description: Occurrence
Location Method: Conversion from MDI
Access Description: The occurrence is located approximately 3.6 km north-northeast of Trafalgar Bay of Northern Light Lake. Northern Light Lake is located 96 km west of Thunder Bay. Access to the property is as follows: from the Northern Lights Lake landing east for 1.5 km, take a bush trail north for 200 m, this trail connects to a logging road. Follow the logging road northwest for 4.5 km, take a bush trail northwest for 3 km. This connects with another logging road. Take this road northwest for 6 km to a fork in the road, take the left fork for 200 m. The occurrence is on the northwest side of the road.
The area had seen no exploration for industrial minerals prior to 1992. 1992 R.R. Parker located a new soapstone occurrence and staked a single claim over it. 1994 R.R. Parker still holds the occurrence.
Province: Superior
Subprovince: Wawa
Terrane: Wawa-Abitibi
Geological Age: Archean
Dec 07, 2005 (R Degagne) - The area is underlain by Precambrian igneous and metamorphic rocks of the Wawa subprovince. The occurrence is hosted in a serpentinized ultramafic, possibly peridotite. The occurrence is exposed as a series of small outcrops over a strike length of 56.4 m. The outcrops observed were very small, highly fractured and deeply weathered.

Dec 07, 2005 (R Degagne) - Veinlets of asbestos-like chrysotile are abundant at the eastern end of the exposure. The veinlets area typically less than 1 cm in width and display a fibrous texture. Clots of whitish to ivory coloured material are seen, these could be serpentine which has been stripped of its iron to produce the magnetite veinlets. Sulphides are rare and when seen are fine-grained pyrite.

Geologist: R Degagne
Notes: Visited in June, 1992 by P. Hinz | R. M. Landry (OGS OFR 5889, 1994). COMMENTS/RECOMMENDATIONS: A slabbed sample displayed reticulate and anastamosing magnetite veining. The sample appears quite similar to samples from the Puddy Lake occurrence. The stone is carvable, however, the abundance of magnetite would make it difficult to work with.
