NORTH-WESTERN DISTRICT (No. 1).

This company was incorporated in 1929 to take over the Unicorn group of

Unicorn Mining eight Crown-granted claims, and two other claims, situated in the upper

Co., Ltd. Salmon River yalley. Five hundred thousand shares of the capital stock of

(N.P.L.). the company were issued for cash and 500,000 shares transferred to the

vendors of the claims. The property is situated between Harris creek and

the Missouri ridge, immediately north of and adjoining the Big Missouri. ‘Through the courtesy

of R. H. Stewart, H. L. Batten, and associates, consulting engineers, the following information
is made available :—

Extensive and systematic exploration by open-cutting and stripping has been carried out on
a series of east-west and north-south striking shear-zones. The result of this work will form
the foundation of the underground exploration that is now being undertaken by the company.

The showings on the property are confined to a west zone and an east zone. The west zone
on the Good Hope claim is a zone of mineralized porphyry striking north-westerly and dipping
west. A series of east-west striking, southerly-dipping shear-zones, A, D, E, and F, and two
north-west striking, westerly-dipping zones, B and C, occur in this area. From systematic
sampling in the numerous open-cuts on B, C, D, E, and F, assays of about 0.20 oz. to the ton in
gold and about 1 oz. to the ton in silver have been obtained across widths of from 8 inches to
3 feet, with an occasional high gold assay. Vein A is a mineralized shear-zone 40 to 50 feet
wide, carrying generally low values in gold and silver, but showing a tendency for better mineral-
ization near the foot-wall. The occurrences in the west zone show a general erratie distribution
of values, with, however, a tendency for improvement at the intersections of cross-fracturing.

Underground exploration of the various showings of the west zone has been carried on from
No. 2 tunnel, driven in a westerly direction to intersect C vein. No. 3 tunnel has been started
near the south line of the Good Hope claim and is being driven in a N. 25° W. direction. At the
end of September this tunnel had advanced 60 feet to the fringe of the west porphyry-zone.
It is expected that D vein will be cut at about 200 feet from the tunnel portal, E vein at about
550 feet, A vein at about 750 feet, and a point vertically below No. 2 tunnel, with 200 feet of
backs at about 1,100 feet. It is planned to drift on the various veins from the points of
intersection by No. 3 tunnel.

Veins H and I occur in the tuffs of the east zone. They differ from those of the west zone
in that they have better definition and the principal values are in silver. Vein H strikes north-
south and dips flatly west. It is a quartz vein 24 to 30 inches wide, mineralized with pyrite
and sparse galena and zinc-blende. Samples from several cuts assay from 0.15 to 0.2 oz. gold
to the ton and from 6 to 22 oz. silver. It has been traced about 250 feet.

Vein I has been stripped for about 100 feet. It is a quartz vein striking east and west and
dipping at 45° to the south, 12 inches to 3 feet wide, mineralized with pyrite, zinc-blende,
and some galena. Native silver is said to occur in this vein. Samples across 10 to 24 inches of
vein I assay from S80 cents to $4 in gold and from 3.5 to 28 oz. in silver. This vein converges
towards an intersection with vein H and shows a tendency to better values towards the latter
vein.

Although the exploration of the showings on this property have not yet exposed ore-bodies
of commercial extent, the encouraging values and indications obtained by the extensive surface
exploration carried out justify an intensive underground exploration. Camp has been erected
for the continuation of the work during the winter, and it is understood that the company plans
the installation of a power unit for aggressive exploration during the 1930 season.

This property is situated 6 miles up the Salmon River glacier, on the western

Outland side, and consists of fourteen claims, all Crown-granted. The formation is a

Silver Bar Mines, much-altered argillite merging into a highly siliceous rock, with a series of

Ltd.* quartz-porphyry dykes running through the property on a general east-west

trend. To the north of the dyke system there is a large irregularly shaped

mineralized mass, consisting of siliceous matter impregnated with galena, zinc-blende, pyrite,

pyrrhotite, and chalcopyrite, and, at least in one place, arsenopyrite. It is said to carry fair

gold and silver values. A number of short tunnels have been driven into this mass at various
elevations from 3,168 to 3,507 feet and all are in consistently mineralized matter.

On the south side of the dyke system and extending to the top of the bluff above the camp
are several outcroppings of small veins, consisting of brecciated argillites, with the fissures filled
with quartz, calcite, galena, zinc-blende, and some grey copper. The walls generally are well
