68 REPORT OF THE MINISTER OF MINES, 1929.

defined. The most promising showing is known as Johnnie’s vein. This was cut by the No. 6
erosscut at elevation 3,882 feet, at about 400 feet in from the portal, and was drifted on for a
short distance north and south. The vein, which strikes north-south and is nearly vertical, is
well mineralized. It is about 4 feet wide in the south drift and 8 feet in the north. It is cut
by a dyke running approximately N. 45° W., but continues on the north side with little or no
displacement.

About 250 feet to the north there:is an outcrop of what is almost certainly the same vein,
and a drift, known as Johnnie’s Vein Outerop tunnel, has been driven for a short distance at an
elevation of 4,069 feet. There is a good showing at the face of 4 feet 6 inches of well-mineralized
vein-matter. A chip sample over 3 feet 6 inches assayed: Gold, 0.1 oz. to the ton; silver, 61.2 oz.
to the ton; lead, 10.2 per cent.; zine, 14.8 per cent.

Another vein, known as No. 1, which has an average strike of N. 45° W. and dips 55° south-
east, has been driven on in two places at elevations 4,049 and 3,890 feet respectively. It averages
about 1 foot in width and contains a high proportion of galena and zine-blende. A crosscut just
above the surface of the glacier, at an elevation of 3,168 feet, has been started from a point to
the south of the dyke system and will be driven due west to prove the continuation in depth
of the No. 1 and Johnnie’s veins. Another crosscut at an elevation of 3,100 feet is projected from
a point to the north of the dyke system, which will also be on a west course. This should prove
the heavy sulphide mass. Gold and silver values are said to be fairly consistent, both in the
heavy sulphide zone and in the smaller veins. The gold values are said to be higher when
copper is present.

The equipment consists of a 212-cubic-foot Ingersoll-Rand compressor and a drill-sharpener,
There is also a well-equipped assay office, with a crusher and grinder run by a small gasoline-
motor. This property appears to have possibilities and it is being developed in an efficient and
systematic manner.

This property is situated on the east side of the Salmon River glacier, almost

Silver Basin.* opposite the Boundary glacier, and is owned by Fitzgerald Bros., of Hyder.

The showing occurs on the north wall of a small canyon coming in from the

east. It consists of a mineralized zone of shattered argillites containing stringers of quartz,

calcite, galena, zinc-blende, and some pyrite. Not enough work has been done to form an

opinion as to its value, but it is certainly worthy of further exploration. A chip sample over

a 42-inch width of the zone assayed: Gold, trace; silver, 8 oz. to the ton; lead, 7.8 per cent. ;
zine, 4.6 per cent.

Unvuk River SEcTIoN.

In view of the apparent promising mineral possibilities of the eastern contact margin of this
section and the fact that it has been sadly neglected in recent years a recapitulation of some of
the available information pertaining to this area may serve a useful purpose. It would seem
that the eastern contact margin accessible from the Unuk river and that in the Stikine Division,
accessible from the Whiting river, offer very promising and practically virgin fields for the
prospector. The Unuk River section forms the extreme north-westerly area of the Portland
Canal Mining Division. Reference to the contact margin of the section is made in the summary
to this report. In the following excerpts from previous reports on the section it will be noted
that some fairly extensive development was carried out in the Unuk River section between the
years 1900 and 1903. Doubtless the reported turbulence of this river and great transportation
difficulties have retarded the subsequent development of this area.

In the Annual Report for 1901 is the following reference to the Globe and Cumberland
groups. On the Globe group “the owners have installed, at considerable trouble and expense,
a small stamp-mill with a capacity of 8 tons per twenty-four hours, with concentrating-table and
copper plates. The motive power is an overshot wheel of 13 feet diameter, developing 10 horse-
power. The ledge is stripped for 400 feet.” On the Cumbderland group, ‘two 5 by 6 tunnels,
each 50 feet long, have been run and 80 tons of ore stoped out ready for shipment; 35 miles of
trail have also been built.”

The following is an excerpt from the Annual Report for 1903 of a letter written by D’Arcy
Macdonald, Deputy Mining Recorder for the Unuk River at that time: “ Leaving the granite,
the next formation gwe encounter is a greenstone or serpentine, which extends up the river for
some miles, where it forms a contact with a dolomite. At the contact, which has a south-easterly
trend, the ledges of the different ores occur, having in nearly all instances a quartz gangue,
