Sep 28, 2011 (A Wilson) - Crysotile asbestos occurs in a series of interlocking stingers in the serpentinized peridotite. The stringers are very narrow, and the fibres rarely exceed half an inch in length. A cross-fibre asbestos zone approximately 4000 feet long and 200 feet wide was present along the north shore of the west arm of Lloyd Lake. There are two ore zones within the differentiated sill. Asbestos fibres typically range from 1/8 to ¼ inch
