On Gnawed mountain, some 25 miles from Ashcroft, and about half that distance from Spatsum station, on the Canadian Pacific railway, there are a number of claims valued for copper. On the claims of the Tamarack group the copper ore is principally chalcopyrite, with a subordinate amount of malachite or green copper ore near the surface. These copper deposits appear to be impregnations along parallel joint planes running east and west in the grey granitic rock of the mountain. In most of them a l...ittle molybdenite is found, but in this regard the Tamarack claim differs from the rest, in that it was first valued for molybdenite. In the other claims of this group the molyb- denite is present in only very small proportions. Occasionally, quartz veins carry copper ore, and this is particularly true in some of the Tamarack work- * G. M. Dawson, Report, Geological Survey, p. 157R. 1S88. 2 O. E.

The molybdenite forms very showy surfaces of fine grained mineral, par- ticularly on cracks and joints, but the thickness is quite insignificant.
