Dec 07, 2005 (R Tuomi) - Although most of the ultramafic body was mapped as hornblendite by Ferguson (1966), this particular outcrop was mapped as serpentinite. The outcrop examined is located in the southeast arm of the intrusion. The rock is fine-grained and very dark green in colour on its fresh surface. The outcrop is cut by minor white calcite veinlets. Joints oriented 040, 146, and 170 degrees spaced a meter or less apart are prevalent. There is a 2 to 4mm rusty weathering rind on the surface. Fine grained disseminated pyrite is present.

Dec 07, 2005 (R Tuomi) - Suffron Lake Hornblendite-Serpentinite. Two tounges of altered ultrabasic rock outcrop in the northern part of the township on the northwest and southeast sides of Suffron Lake. These dykes trend in a southwesterly direction, but the more southeasterly dike is rather irregular in strike. As shown on a previously published preliminary map (P.124) by [Ferguson], farther northeast in McDonough township, these dykes range in width from 350 feet to 1200 feet. Many outcrops of these rocks are medium-grained and contain abundant amphibole, but in other places the rock is very soft and appears to be fine-grained and is strongly serpentinized. Some inclusions of country rocks are found within the Dykes. On claim KRL 1640 of the Kaymac property, a few veinlets about 1/2 inch in width contain cross-fibre chrysotile - asbestos.
