50 REPORT OF THE MINISTER OF MINES, 1929.

easterly dip of the vein and the indication of displacement-by a northerly-striking shear-zone
may have thrown the yein farther to the eastward than the position of the tunnel-face at the
time of examination.

When the downward extension of the south-west vein is located it is planned to drift north-
east to explore for the continuation at depth of the ore-shoot indicated in the surface cuts.
The yein will then be drifted on to explore for ore-shoots towards No. 2 tunnel. The progress
of this work will also involve crosscutting at depth for the Bullion vein and the intersection
of that vein with the main vein. .

The veins can be traced on surface for appreciable distances, with altitude variation of
from 3,180 feet at No. 3 tunnel to 3,600 feet at No. 1 tunnel. Beyond this the main vein was
traced to about altitude 4,600 feet, but snow on the higher elevations obscured its further possible
tracing. The main yein, which is apparently a silicified zone averaging about 14 feet wide, does
not carry encouraging mineralization. A sample of the general character of this vein selected
at 4,000 feet altitude assayed: Gold, trace; silver, trace.

In No. 1 tunnel widths of from 4 to 30 inches have been drifted on for about 140 feet, with
reported values of from 60 cents to $170.24 in gold and silver.

At the time of examination (middle of October) the face of No. 2 tunnel showed a sheared
zone with quartz stringers, sparsely mineralized with pyrite.

The Bullion tunnel has been described in the 1922 Annual Report. The occurrence is in an
inclusion pendant of andesitie rocks of undetermined depth underlain by diorite.

This property is situated on the ridge east of the divide between Bulldog creek

North Country and Georgia river. It is reached by a very bad trail which leaves Burnt point,

Mining Co., Ltd.* on Portland canal, and crosses the 3,300-foot ridge between the canal and

Georgia river. Stores and material are packed in on men’s backs at a cost

of 15 cents a pound. Development is being concentrated on the following claims: Glory, Glory
Extension, Ventura, and Fortuna. A. Linke is in charge.

At the time of examination work was being concentrated on driving two crosscuts through
a hard metamorphosed argillite in an easterly direction. The lower one is just above the valley-
level and was in 50 feet; the upper, about 100 feet higher up, was in 20 feet. Approximately
400 feet higher up the hill and some distance to the south a little work has been done in a gulch
running down the face of the hill. The rock is mineralized in places, with small showings of
zinc-blende, chalcopyrite, and traces of galena. In the same gulch and 150 feet higher up there
is a drift in a northerly direction, which is in about 60 feet. Here also are patches of minerali-
zation, consisting of pyrite and galena with a little arsenopyrite. Another small cut on the
opposite side of the gulch also showed slightly mineralized matter.

Considerably farther south, possibly half a mile, and at about the same elevation as the
above, there is a strong outcrop of quartzite, averaging 4 feet in width, crossing a deep gulch.
I was unable to find any evidences of mineralization in it, but to the west there was a little
zine-blende and pyrite. ‘

The apparent strike of the showings is north and south. The dip is vertical or steeply to
the east. No ore of commercial value has been found so far. A log-built bunk-house is being
put up close to the lower crosseut.

Just beyond the present end of Bulldog Creek trail is a difficult stretch along a vertical bluff.
Once that is passed there should be no difficulty in maintaining a reasonably even grade to the
top end of the valley, a distance by estimation of at least 3 miles.

Marmot River Section.

The ore-deposits of this property are described in former Annual Reports.
Porter-Idaho, The property is now being operated by the Premier Gold Mining Company.
The following information regarding the year’s operations has been kindly

supplied by D, L. Pitt, manager, Premier Gold Mining Company, Limited :—
“At Porter-Idaho an aggregate of 1,316 feet of drifting and raising was done during the

year. This was accomplished in yarious tunnels and on various horizons. Some small and

narrow shoots were outlined and will be mined later. Tunnels were also run into the Porter-
Idaho ground from Prosperity’s No. 3 level and some ore-bodies indicated.

“Efforts were concentrated upon the completion of the Porter-Idaho tramway,
completed early in September and put into operation.
