cular quartz veins up to 8 inches wide. The faults are filled in part with
sheared and brecciated granite. Two large trenches about 100 feet apart
have been blasted out along the veins. In the more northerly trench the
veins are very narrow. A grab sample of quartz from the lower trench
was assayed for gold and silver with negative results.

A quartz albite dyke, cutting granodiorite, outcrops about 800 feet
to the northwest at an elevation of 825 feet. The dyke is 6 feet wide,
strikes south .70 degrees east, and dips almost vertically. A pit has been
sunk on a quartz vein 6 inches wide that follows the south wall of the
dyke. The quartz is lightly mineralized with pyrite, and the granitic
wall-rock has been altered and pyritized over a width of a few inches. A
channel sample taken across the vein assayed only a trace in silver and
no gold.

About 500 feet farther northwest, along the west slope of the hill, a
large pit has been sunk on a sheared and mineralized zone in granodiorite.
The shear zone strikes north, is 10 to 15 feet wide, and in it the crushed
rock has been partly converted to tale schist.

The zone is cut by many quartz stringers and veinlets that carry
small amounts of hematite and specular hematite. A sample of the
mineralized quartz was assayed, but showed no gold nor silver.

The Globe claim, owned by E. T. Kenny of Terrace, is on the lower
slopes of Thornhill mountain, a short distance from the Lakelse Lake road,
and is about 6 miles by road southeast of Terrace. It was first staked about
1910 and was known by its successive owners as the Iron Hat, Golden Nib,
and Star claim. Only assessment work has been done since 1926 when it
was worked under bond by O. P. Brown.

A strong shear zone 5 to 15 feet wide in coarse-grained granodiorite
may be traced up the side of the mountain for about 1,000 feet and for a
vertical distance of 600 feet. It has an average strike of north 50 degrees
east and dips 70 degrees southeast. Lens-shaped bodies of quartz, some
of them mineralized with pyrite, occur in the shear zone. The granodiorite
for a distance of at least 100 feet on either side of the shear zone con-
tains many small veinlets of epidote and is sheared and altered with a
strong development of biotite. There are a number of finely crystalline,
dull grey, andesite dykes, spotted in places with epidote. One of these
is 20 feet wide and has been cut off sharply at the shear zone near the
entrance to a lower adit. What is believed to be the offset continuation
of ue dyke lies on the west side of the shear zone about 250 feet to the
north.

The main adit at an elevation of 370 feet above the Lakelse Lake road
has been driven for 110 feet along the shear zone in a direction north
50 degrees east. The first 50 feet are in schist with quartz stringers.
