The Mount Soues chrysotile (asbestos) occurence is located "in the southern base of Mount Soues, near Junction Valley" (GSC Annual Report 1894, page 345). The location appears to be about 11 kilometres southwest of Clinton, above the B.C. Rail tracks.
At this location, bedrock is mapped (GSC Map 1278A) as argillite, basaltic flows, tuff, chert and limestone of the Permian to Triassic Cache Creek Complex. Serpentine and other ultramafic rocks are known to be associated with the Cache Creek Complex rocks at other locations, and could be present in this area.
There is no information on the deposit other than "small veins of chrysotile or serpentine asbestos have been observed in or near some of the deposits of serpentine in ... the Cache Creek rocks" (GSC Annual Report 1896, page 345).
