Jul 24, 2013 (A Wilson) - The Loch Lomond Deformation Zone (LLDZ) is defined by an arcuate zone of highly strained rocks (800 to 1600 m wide) and varies in trend from NE through E to SE. The western part is defined by several 1-30 m wide NE-trending ductile shear zones. Within these zones, mafic to intermediate metavolcanic rocks are deformed to chlorite or amphibole schist. Along the southern shore of Loch Lomond, the LLDZ is defined by narrow, east-trending ductile shear zones in amphibolitic metavolcanics and a wide zone of sericite-quartz-pyrite schist south of Loch Lomond. This large zone of ductile shear is greater than 30 m in width and can be traced as far eastward as the Meath Lake Fault.

Jul 24, 2013 (A Wilson) - The area has been mapped as a narrow band of mixed sericite schist and sheared argillaceous sediments. Amax interpreted the rocks as consisting of sheared bands of meta-greywacke, feldspathic arkose and argillite. Blocks of sericite schist carrying up to 20% pyrite are found across a width of approximately 45 m.
