the rust-stained material contains nodules and crystals of wolframite
up to 2 inches in diameter, the wolframite crystals are intergrown with
quartz and are so rust stained that their presence might easily be over-
looked; a narrow, porphyritic diorite dyke that pinches out at the top
of the cut; a 3-inch quartz vein containing a little pyrite and chalcopyrite.
The granodiorite along the hanging-wall side contains large sericite crys-
tals, some of which are an inch in length. A 12-inch channel sample taken
across the leached, rust-stained material alongside the dyke assayed:
gold, 0-005 ounce a ton; silver, 5-93 ounces a ton; tungsten, 12-58 per cent.

In the main cut on the bench at elevation 5,000 feet, the zone con-
sists of 18 inches of sugary, leached vein quartz containing about 2 per
cent of molybdenite, 1 per cent of chalcopyrite, and 5 per cent of pyrite.
An 18-inch channel sample taken across the leached vein material in this
cut assayed: gold, a trace; silver, 1-64 ounces a ton; tungsten, none.

The Highland Boy claims are immediately east of the Rocher Déboulé
group, about 11 miles by road northeast from Skeena Crossing. The road
follows the valley of Juniper Creek, keeping on the northwest side of the
stream. The claims blanket a precipitous mountain ridge whose peaks
rise to elevations exceeding 6,500 feet. This property was first prospected
by Butte-Rocher Déboulé Copper Company, Limited, in 1912. The Delta
Copper Company of Edmonton secured the property in 1917 and carried
out some development work. In that year a shipment of 74-92 dry tons
of ore was made to Ladysmith smelter, which returned 10,494 pounds
of copper, 4 ounces of gold, and 35 ounces of silver. In 1919 and 1920
a little further work was done, and in 1921 Lynch Brothers of Spokane
are reported to have done some diamond drilling. Since then nothing has
been done on these claims.

A number of fissure zones occur on this property in the coarsely
crystalline, grey granodiorite that forms the core of Rocher Déboulé
Mountain. The two principal zones strike in an easterly direction and
dip from 45 to 80 degrees north. One of these zones is an easterly
continuation of the main upper zone on the Rocher Déboulé group. From
the most easterly adit, at elevation 5,160 feet on the latter property, this
zone extends east across the Timber Line, Iowa, and Coral Queen claims
to the Highland Boy claim of the Highland Boy group. The length of
this fissure approaches 1 mile across the two properties, but no work has
been done on it east of the old adit on the Timber Line claim. Its outcrop
is largely concealed by talus. The main fissured zone of the Highland Boy
group lies about 700 feet farther north. It has been followed for 3,500 feet
in an easterly direction across the Delta Fraction, Balmoral, Zig Zag
Fraction, and Golden Fleece claims. At its east and west ends, the
outcrops are above an elevation of 5,700 feet. Midway along its strike,
between elevations of 6,400 and 6,500 feet, the zone is almost inaccessible
where it crosses sharp, jagged peaks.
