Dec 07, 2005 (C Salo) - Talcose rocks in the area are hosted within mafic metavolcanics or at the contact between mafic and felsic metavolcanics. The talc zones, which range in width from 10 cm to 30 m, occur within 180 m of the Weslemkoon batholith (Lumbers 1968)(see Figure 36).

Dec 07, 2005 (C Salo) - STONE DESCRIPTION: The stone is described as a greenish, fine- grained, chlorite talc schist locally containing abundant dolomite. Semi-chloritized hornblende is also reported in some bands. In part however, the rock is more massive than foliated and is referred to by Spence (1940) as soapstone, who suggests it might be used for 'sawing into blocks'.
