34 REPORT OF THE MINISTER OF MINES, 1929.

and about 1 mile from the beach. The ore occurrence is zinc-blende, galena, pyrite, pyrrhotite,
and a little chalcopyrite in a glassy quartz, in the Prince Rupert schists. The mineralization
is developed along small chloritized seams in the quartz. The owner reports a width of about
50 feet exposed in the bed of a creek by some stripping and a few shallow holes, and claims to
haye traced the vein outcropping a distance of about 400 feet, striking east and west, with
undetermined dip. A sample reported by the owner to have been taken across about 12 feet in
the centre of the vein assayed: Gold, 0.01 oz. to the ton; silver, 2.5 oz. to the ton; copper,
trace; lead, 4.3 per cent.; zine, 2.82 per cent.

At the head of Klekane inlet, off Fraser reach, a hot calcium-sulphate and
Thermal Springs. sodium-chloride spring occurs about 600 feet from the beach and about 20 feet

above high tide. On the shore of Ursula channel, about 234 miles north of
Fisherman cove, a small hot spring issues from the quartz diorite about 1 foot above high tide.
On this channel at the west side of Bishops cove a spring occurs about 60 feet from the shore
and 10 feet above high tide. On Gardner canal, between Shearwater and Low points and about
12 miles from the entrance into Desolation channel, a very hot spring issues from the edge of
a small cliff and about 2 feet above high tide. A hot spring also occurs on the south-east side
of Brim river, 200 yards above the mouth. Brim river flows into Gardner canal 20 miles from
its entrance into Desolation channel,

CANADIAN NATIONAL Rat~rway SECTION.

This section has been comparatively inactive. Between Prince Rupert and Terrace the bulk
of the rocks belong to the Coast Range granodiorite batholith. There are in this stretch, however,
several areas worth prospecting and the batholith itself should not be entirely neglected, par-
ticularly in localities where it shows zonal shearing and fracturing,

The Prince Rupert series contacts with the batholith at about mileage 16. Inclusions of
basic schists from 2 to 6 miles wide occur at about mileages 36, 46, and 68. The eastern contact
margin of the batholith crosses the railway at about mileage 82, from which point there is an
exposure 8 miles wide of the Kitsalas series of Triassic porphyrites, andesites, tuffs, and breccias.
Although this contact area is in the disturbed zone, featured by considerable fracturing and
crushing and intrusions of numerous granitic dykes, a condition adverse to ore-deposit continuity,
some of its mineral-deposits may warrant exploration and it is worthy of prospecting. The
easterly edge of this band of Triassic yoleanies is covered by the alluvial flats of the Kitsum-
gallum river, to the east of which, at Terrace, a wide spur from the batholith comes in. Several
groups of claims are staked on cupriferous ores in the Kitsalas series in the neighbourhood of
Amsbury. Of these the most extensive work has been done on the Autumn group.

This group of five claims is owned by George and Sam Alger, of Usk. It is

Autumn. situated 8 miles west of Amsbury Station, about three-quarters of a-mile north

of the old Lakelse sawmill, and about 83 miles east of Prince Rupert. The ore

occurrence consists of a rather erratie distribution of chalcopyrite and pyrite in silicified zones

in altered andesite bordering crystalline limestone. Mineralization occurs in granular dissemi-

nations and yeinlets and is confined to the more siliceous parts of the formation. At some spots

pyrite is developed in massive bunches 18 to 24 inches wide. Pyrite is the predominant mineral.

The wallrock is heavily epidotized. In two places a massive development of magnetite in
contact with limestone has been exposed.

Three hundred feet west of the cabin at 225 feet altitude surface cutting and stripping
exposes a zone 3.5 feet wide of quartz and epidote mineralized with chaleopyrite and pyrite
striking N. 10° W. and dipping steeply south. A chip sample across 5.5 feet from the top of
this open-cut assayed: Gold, trace; silver, 0.2 oz. to the ton; copper, 1.3 per cent. Twenty feet
south of this cut a crosscut tunnel 15 feet long exposes similar mineralization. A crosseut
tunnel 120 feet in length at 25 feet lower altitude penetrates crystalline limestone at the face,
but failed to cut mineralization. At 70 feet in, a 20-foot crosseut to the east and one 25 feet

-to the west also failed to cut the mineralization.

At altitude 250 feet and 200 feet south of the above workings a cut 5 by 30 feet exposes
3.5 feet of banded mineralized andesite striking N. 32° PB. and dipping 80° 8. A sample repre-
sentative of this cut assayed: Gold, 0.01 oz. to the ton; Silver, 0.3 0z. to the ton; copper,

2 per cent. Thirty-five feet below this cut a crosscut tunnel for 40 feet penetrates limestone,
but failed to cut mineralization.
