The country rock is tuffaceous sandstone, quartzite, and argillite cut by dykes of porphyritic granodiorite. The strata strike north 40 degrees east and dip 35 degrees northwest. At an elevation of approximately 6,000 feet these sediments are intruded by the granodiorite stock that occurs to the west.

The main ore occurrence is a replacement type of vein occupying a shear zone. The vein varies in width from 10 inches to 24 feet, strikes north 75 degrees east, and dips 60 degrees to the southeast. It consists of sphalerite, galena, pyrite, tetrahedrite, and chalcopyrite in a gangue of quartz, carbonate, and altered wall-rock. In places the vein is con- siderably leached and consists largely of iron oxide.

At an elevation of 5,200 feet, an adit has been driven along the vein for 30 feet. Here the vein is from 10 to 12 inches wide and well mineralized with pyrite, tetrahedrite, and sphalerite. According to Lay,1 a sample across this width assayed: gold, trace; silver, 54 ounces a ton; lead, nil; zinc, 4 per cent. One hundred and seventy-five feet farther up the slope the vein has been exposed by an open-cut. At this point it is 25 feet wide and contains much pyrite and a little sphalerite in an 8-inch band next to the foot-wall. A sample across 10 inches assayed: gold, trace; silver, 3 ounces a ton; lead, nil; zinc, 6 per cent.2 What appears to be the same vein is exposed at an elevation of 5,900 feet, where it is 2 feet wide. Selected ore samples assay: gold, 0:06 to 0-18 ounce a ton; silver, 76°5 to 203-4 ounces a ton; lead, 22 to 36 per cent; zinc, 20 to 30 per cent.

Higgins Property* (14)

This property is situated in a cirque on the north slope of Netalzul Mountain between elevations of 4,500 and 6,000 feet. It is reached by a pack-trail, 24 miles in length, that branches south from the Hazelton- Babine trail at a point 30 miles east of Hazelton.

A granodiorite stock intrudes the sediments on Netalzul Mountain. The contact crosses the property and the mineral showings occur within 500 yards or less of this contact both in the granodiorite and the sediments. The sediments, which are argillite, quartzite, and hornfels, strike north 40 degrees east and dip 35 degrees northwest.

The showings consist of a sulphide vein 4 inches wide and several quartz veins 2 to 7 feet wide. At elevation 4,500 feet the sulphide vein is exposed for 20 feet in an open-cut. It occurs along a small fault in the sediments less than 50 yards from the granodiorite stock. The vein strikes north 60 degrees east and dips 60 degrees southeast. It consists of sphalerite, galena, and tetrahedrite, sphalerite being the most abundant mineral.

Well within the granodiorite, at an elevation of 5,500 feet, a quartz vein 4 feet wide has been exposed by a 9-foot pit and surface stripping.
