Dec 07, 2005 (A Wilson) - The peridotite body underlies most of Lena Lake and outcrops only on islands within the lake. The lake is associated with a pronounced aeromagnetic anomaly. This intrusion and several others in the area appear to be spatially related to the Magpie River Fault which separates NE-striking stratigraphy from SE-striking stratigraphy. The Magpie River Fault has been interpreted as a major thrust fault. The Lena Lake intrusion may be the faulted equivalent of the Mildred Lake intrusion. The peridotite intrudes clastic metasediments and mafic metavolcanics.

Jan 09, 2016 (A Wilson) - The peridotite is massive and weathers to a dark green to black in colour. This intrusion is less heavily serpentinized than the Sunrise Lake periodotite in Esquega Township. The rock is described in drill core as a talc-epidote schist.

Dec 07, 2005 (A Wilson) - The original description of the occurrence (1926) described bright green fibres that were identified as serpentine. The asbestos occurs in veinlets and patches which are 1/8 - 1/4 inch wide and vary in length from 2 to 4 feet. The asbestos forms less than 1% of the outcrop. Assays returned poor nickel values (0.005% - 0.1%).
