Dec 07, 2005 (C Papertzian) - A 3 Km ( 1973 ) wide group of ' tremolite marble alternating with well-layered, fine-grained, grey marble '. The tremolite makes up 10-30 % of the rock, the rest being fine-grained white dolomitic and magnesian marble. Tremolite colour varies from pale greenish-white to dark grey and it sometimes develops as radiating masses. Mostly, it occurs in rough layers conformable with the marble layering.

Sep 15, 2015 (A Wilson) - A belt approximately 3 km wide, extending northeast from Sheridan Rapids in Dalhousie Township,is comprised of calcareous rocks that are largely altered to tremolite schist with occasional development of serpentine. None of this tremolite is fibrous and cannot be called asbestos. Some of these areas may be worthy of prospecting for talc. The tremolite-bearing marble alternates with well-layered, fine-grained, grey marble.
