0-015 ounce a ton; silver, 6-53 ounces a ton. A 6-inch sample taken
across 3 inches of quartz and 8 inches of chloritized altered rock 50 feet
farther east assayed: gold, 0-03 ounce a ton; silver, 2-40 ounces a ton.
For 400 feet from the face a lamprophyre dyke follows along or close to
the zone. The dyke is brecciated and altered where it crosses the fissuring,
so that in places it forms part of the gangue along with the altered grano-
diorite. Towards the east end of the drift the zone contains very little
quartz or sulphide and is probably barren.

A third adit, reported to have been driven 170 feet along the zone at
elevation 5,850 feet, was concealed by snow when visited in June. Some ore
of good grade is said to have been taken from this adit. Ore was also
mined from an open-cut 30 feet long, 3 feet wide, and 10 feet deep on the
top of the ridge at elevation 6,025 feet.

Lone Star Claim (27)

The Lone Star claim is on Rocher Déboulé Mountain 6 miles south-
east of New Hazelton. The workings are on Pangea Creek, the south fork
of Mudflat Creek. The owner, Angus White of New Hazelton, has con-
structed an excellent branch trail to the claim from the Mudflat Creek
trail to the Black Prince group.

At elevation 3,950 feet, a pyrrhotite vein is prospected by an open-cut
on the southwest bank of the creek. The vein ranges from 1 to 4 inches
in width and is less than 25 feet long. An adit driven 145 feet in a southerly
direction along the strike of the vein does not disclose any mineralization.
At distances of 175 and 475 feet, respectively, farther up the creek, 30-foot
and 20-foot adits are driven into the southwest bank of the creek along
small fissures, but likewise disclose no mineralization,

The rocks exposed along the banks of Pangea Creek, and on the steep
slopes towards the west, are bedded sediments, composed of greywacke,
slate, and argillite. They are intruded near the workings by several small
dykes of porphyritic diorite and by a large body of eranodiorite 1 mile
to the west. Massive, grey, porphyritic andesite flows outcrop a short
distance east of Pangea Creek and extend easterly to the Bulkley. Both
sediments and volcanic rocks are flat-lying on this claim, and are in fault
contact a short distance east of Pangea Creek. This north-trending fault
is several miles in length. It is exposed on the steep south slope of Por-
phyry Creek and on the ridge on the north side of Mudflat Creek. The
possible occurrence of veins along it has not been investigated, as it is
largely drift covered.

The Black Pilot, True Blue, and Summit claims, staked by Dan
MacDonald in 1926, are between the head of the south fork of Mudflat
Creek and the head of Porphyry Creek, 7 miles southeast of New Hazelton.
The claims are reached by a poor trail that extends up the south fork of
Mudflat Creek from the Lone Star property.
