The TM area is underlain by mafic and intermediate volcanic rocks of the Middle Jurassic Salmon River Formation, Hazelton Group.
The TM (Ted Morris) showing is a large vertical, altered and silicified shear zone, located on a cliff face, along an unnamed creek just to the west of the Ted Morris Glacier. The shear is several metres wide and has a vertical dimension of 400 metres. The mineralized area is approximately three metres wide and consists of a quartz-sulphide alteration zone hosted within intermediate to mafic volcanic rocks. The zone trends about 090 degrees, with a dip of 80 degrees to the south. A one-metre malachite stain marks the area and there is extensive iron and manganese staining throughout the exposure. Mineralization consists primarily of pyrite, arsenopyrite and chalcopyrite hosted within quartz/chlorite veins. An east-west linear feature which runs under both the TM and GFJ (104B 233) showings suggests that the two showings are connected and that the TM showing may be a feeder system for the GFJ showing. A second set of veins can be seen near the top of the ridge above the TM showing. A grab sample from the TM showing assayed 42.17 grams per tonne gold (Assessment Report 24965).
Refer to Cumberland (104B 011) for details of the Corey property, which encompasses the TM showing.
