62 REPORT OF THE MINISTER OF MINES, 1929,

crosscut, At that point the vein is assumed to be faulted. Crosseutting to east and west had
failed to pick up the extension up to the time of examination (October 10th). The character
of the Highgrade vein exposed in this work is similar to that of the Mann yein, with sparse and
irregular mineralization. ‘

During the season a small shipment of about 4 tons of selected high-grade ore was made
from the surface showings of the Highgrade vein above the tunnel. This shipment is reported
to have returned nearly 1.100 oz. silver to the ton. In this showing a mineralization of galena,
zine-blende, argentite, and a mineral thought to be stromeyerite is very irregularly distributed
through the jasper-barite gangue in small kidneys and in 14- to 14-inch veinlets along some of
the cross-fractures. This character of mineralization favours generally § to 18 inches of the
vicinity of either wall and can be picked up at irregular intervals over a distance of about
100 feet. To recover appreciable quantities of high-grade ore for shipment from this surface
showing, very close selective mining and sorting would be necessary. A sample of carefully
selected ore from these kidneys and veinlets assayed: Gold, trace; silver, 529 oz. to the ton;
copper, 2.5 per cent.; lead, 16 per cent.; zinc, 8 per cent.

When the continuation of the Highgrade vein is located underground, future operations are
planned to explore for the continuity and extent at depth of the high-grade ore-shoot indicated
on surface. Exploration from the Mann tunnel for the underground intersection of the High-
grade vein with the Mann vein is also planned. ;

It is planned to continue operations during the winter from a crosseut tunnel starting a
short distance north of the bunk-house at about altitude 2,400 feet. At the intersection of this
tunnel with the Mann vein a raise will be started to connect with the Mann tunnel. The black-
smith equipment has been moved underground and the space between the winter crosscut portal
and the drier-room will be covered in to shelter from severe snow conditions.

The property is equipped with an Ingersoll-Rand 810-cubic-foot, gasoline-driven, portable
compressor installed at about 1,700 feet altitude.

This group of nine claims, owned by W. Bosence and partners, of Stewart, is

Lucky Jim. situated on the west side of American creek, adjacent to the Mountain Boy.

The showings are reported by the owners to consist of a quartz-jasper-barite
vein, 7 feet wide, carrying mineralization of galena, some chalcopyrite and bornite, and a little
grey copper, in an andesite formation.

Four hundred feet. west and at about 1,000 feet higher altitude a silicified replacement zone
about 13 feet wide, showing mineralization with chaleopyrite and bornite, is reported to haye
been stripped and open-cutted in places. Three other showings mineralized with pyrite and
galena, but on which no work has been done, are stated to occur on the property. Late in the
year it was reported that Montreal interests had concluded negotiations for the acquisition of
these claims, with a view to carrying out exploration on them during the 1930 season.

Options have been procured by this company on the Ruby, Blue Jay, Maybee,

Shuniah Mines, Louise, and M. and M. group, comprising thirteen claims and one fraction,
Ltd. situated on the west side of American creek, east and north of the Mountain

Boy and Lucky Jim. The project is being financed by the Osisko Rouyn

Exploration Company, of Montreal. Date in October camp was established and operations
started under the direction of W. J. Trethewey, of Montreal, with a view to preparing the
showings for a thorough sampling. Exceptionally heavy rains greatly hampered the progress
of the work, most of which was devoted to trail-construction to the showings on the Ruby claim.

Of the three veins reported to occur on the Ruby, only the lower vein, at about altitude
1,900 feet, had been opened up. On this there are two open-cuts about 500 feet apart. This vein
was examined where it crosses a creek at about altitude 1,800 feet elevation. Here there was
exposed a quartz-jasper-barite zone of appreciable but undetermined width and attitude and
somewhat brecciated structure. Mineralization at this exposure was very sparse, but an
occasional small patch of what might possibly be silver sulphides associated with galena, chal-
copyrite, and bornite can be seen. Time did not allow other showings reported to oecur on the
property to be examined.

These groups, comprising twenty-four claims, owned by C. M. Bryant, Mathew

B.L.K., Bryant, Little, and D. D. Kimball, of Stewart, are situated on the east and west side
Dundee, and of the head of American creek at about 4,300 feet altitude. The claims were
Virginia K. staked during the middle of September on discoveries made by D. D. Kimball.
The owners report exposures of galena ore 3 to 4 feet wide occurring at
