and is replaced in a number of places by small veinlets of quartz, sphaler-
ite, Jamesonite, and galena. At elevation 4,840 feet the four fault fissures
are exposed in a second large open-cut, but there three fissures are mostly
barren.

The main adit, at elevation 4,800 feet, was driven south into the
mountain to explore the veins exposed by the two large open-cuts. The adit
follows the fissured zone in a south by west direction for 445 feet, turns
southeast and continues 280 feet through massive granodiorite. From the
portal a 4-inch quartz vein carrying about 30 per cent sulphides is followed
south for 40 feet to where the adit swings more easterly and, 30 feet
farther along, exposes two quartz-sulphide vein lenses each 1 foot wide
and 10 feet long, arranged en échelon. A 12-inch channel sample taken
across the best mineralized lens, containing about 60 per cent of sulphide,
assayed: gold, 0:005 ounce a ton; silver, 4-77 ounces a ton; lead, 5-98
per cent; zinc, 3-96 per cent. At 140 feet from the portal there is a 3-inch
quartz-sulphide lens 20 feet long with a dip of 30 degrees east. A represen-
tative sample from this lens assayed: gold, a trace; silver, 0:85 ounce a
ton; lead, 1-02 per cent; zinc, 4:72 per cent; antimony, 0-51 per cent.
Between 165 and 190 feet from the portal a 6-inch vein dipping 30 degrees
east is exposed. The fracture along which this vein occurs is followed south
to the point 445 feet from the portal where the adit swings southeasterly.
For most of the distance the fissure has no vein filling, but at intervals
several short, narrow, quartz-sulphide lenses appear.

As there are four parallel fractures over a width of 12 feet in the
surface cuts above the portal of the main adit, it is apparent that a true
picture of the vein system is not seen in the main adit as it is only 6 feet
wide. Short crosscuts driven east and west from within the adit would
intersect nearby parallel veins if present. Raises driven on the vein
between 150 and 300 feet from the portal might intersect members of the
other vein set, which strike east and dip south at low angles.

Forty feet below the main adit a sparsely mineralized shear zone rang-
ing from 1 to 3 feet in width is followed south by a 32-foot adit. The
shear zone dips 45 degrees east and is evidently a downward continuation
of the fracture zone followed by the main adit. Sixty-five feet below the
main adit an exploratory adit runs 117 feet southwest, with a 50-foot
crosscut to the southeast at a point 55 feet from the portal. The shear
zone is cut off at the portal of this adit by a fault that strikes northeast
and dips 30 degrees west.

Between the main adit at elevation 4,800 feet and an upper adit at
elevation 4,985 feet, eight or ten veins have been opened up by stripping
through a light overburden. Most of these are shown on the accompanying
plan (Figure 2). One of these veins, at elevation 4,950 feet, is traced for
70 feet by three pits. It ranges from 6 inches in width at either end to
3 feet in width at the central pit. In the east pit it is joined by a cross
vein ranging from 4 to 8 inches in width. The main vein strikes southeast
and dips 40 degrees southwest, and the cross vein strikes northeast and
dips 30 degrees southeast. The quartz gangue of both veins is abundantly
mineralized with sulphides. A 36-inch channel sample, taken across the
vein in the centre pit, assayed: gold, nil; silver, 1-10 ounces a ton; lead,
2-96 per cent; zinc, 0:40 per cent. In a pit 100 feet farther west there is
