oxidation of a small sulphide content. North of the shaft the vein is
exposed for about 50 feet, and for this distance strikes north 20 degrees
east and dips 75 degrees east. The fault along which the vein occurs
contains no vein quartz where it is exposed 150 and 275 feet farther north-
east. South of the shaft the vein has been followed by stripping and
trenching for 225 feet, and may extend farther beneath the drift cover.
Where exposed the vein quartz ranges from 6 to 10 inches in thickness and
contains occasional pockets of honeycombed, limonite-stained quartz. At
its southern end the strike changes to a few degrees west of south and the
dip remains 75 degrees east.

An 8-inch channel sample taken across the vein 40 feet north of the
shaft assayed: silver, 0-14 ounce a ton; gold, 0:06 ounce a ton. A picked
sample was collected from the dump at the shaft by selecting a dozen pieces
of quartz containing about 2 per cent of a silvery grey mineral, evidently
argentite. The argentite was present as small veinlets in the quartz, and a
little chalcopyrite accompanied it. The sample weighed about 2 pounds
and assayed: silver, 122-78 ounces a ton; gold, 0-02 ounce a ton. A repre-
sentative sample taken from an old ore bin containing the remains of 50
bags of crushed ore assayed: silver, 35-64 ounces a ton; gold, 0-02 ounce a
ton; copper, 0-20 per cent. A fourth sample taken across the vein 30 feet
south of the shaft where there were no visible sulphides assayed: silver,
0-10 ounce a ton; gold, none. The assays seem to indicate the presence of
ore shoots rich in silver in this old mine.

Bornite King Group (22)

The Bornite King group, owned by Andrew Pete of Usk, is on the west
slope of Bornite mountain, about 3 miles east of Usk. The camp at an
elevation of 3,900 feet is reached by a 5-mile trail, which goes up by way
of the Four Aces group.

The claims are underlain by massive, voleanie flow rocks intruded by
occasional quartz-albite dykes and granodiorite tongues.

Small quartz veins are associated with the intrusives, but none of them
appears to carry attractive mineral values.

At an elevation of 3,950 feet, about 200 feet southeast of the campsite,
an adit has been driven south 25 degrees east for 22 feet into barren
andesite on the face of a precipitous slope.

Considerable prospecting has been done on the steep rock sides of a
glacial cirque, particularly on the southeast side. Here, at an elevation of
4,150 feet, an adit was driven south 10 degrees east for 86 feet in porphy-
ritic and fine-grained andesites. The flows strike south 60 degrees east
and dip 45 degrees southwest. One hundred feet above the adit a trench
exposes closely spaced joint planes in andesite. These strike south and dip
70 degrees west, but contain no sulphides. At elevation 4,350 feet two other
trenches about 30 feet apart have been made in barren andesite. A small
cut exposes a vertical fault fissure striking east at 4,500 feet elevation. The
fault contains up to 2 inches of gouge and the wall-rock is stained green for
several inches on either side. At 4,650 feet there is a 6-inch quartz vein
exposed for 100 feet along the contact between two flows. The vein strikes
