passes about 1,100 feet below the property; a switch-back trail leads from
the road up to the mine workings.

There are a number of parallel veins on this property similar to those
on the Silver Standard which is approximately 2 miles due west. These
veins strike roughly north 30 to 40 degrees east, and dip 40 to 70 degrees
southeast; they are offset by a series of small faults, but not to an extent
to cause inconvenience in development.

The country rocks are of the Hazelton series, similar to those at the
Silver Standard, and there are a few small dykes of granodiorite-porphyry
which were earlier than the mineralization.

Since this property was shut down and there were no mine plans
available, it was not studied in the same detail as was the Silver Standard,
which furnished good facilities for an examination and is very similar to
the American Boy occurrence. :

There are three main veins opened up on the property, and a fourth
which may be an extension of one of the others. A good description of
these veins is to be found in the report of the Minister of Mines for British
Columbia, 1914, and the assays given below are taken from that report.

The veins are strong, true, fissure veins which vary from 6 inches to
3 feet in width.

The mine was shut down because the high grade material was not
sufficiently concentrated in the veins to permit of economical mining
unless the second grade material which had to be taken out during develop-
ment was utilized. Since funds were not available to erect a mill the
property was closed. Now that the Silver Standard mine has erected a
mill and will accept custom ore, this property is being reopened and should
become an important producer.

No. 1 vein contains an ore-shoot 90 feet long on the surface, consisting
of galena and zine blende, with lesser amounts of jamesonite, tetrahedrite,
pyrite, and chalcopyrite, in a gangue of quartz. The sulphides frequently
exhibit a banded structure. The vein has been developed by a 100-foot
shaft with short drifts at the 27 and 50-foot levels, and by a 25-foot shaft
a short distance from the main one. A sample across 20 inches on the
27-foot level assayed: gold, 0-10 ounce; silver, 47-4 ounces; lead, 11 per
cent. Picked high grade ore from the 25-foot shaft assayed: gold, 0-10
ounce; silver, 681-2 ounces; lead, 31 per cent.

No. 2 veinis 150 feet southeast of No. 1, somewhat similar in mineraliza-
tion, and is 2 to 3 feet in width. A sample of selected ore assayed: gold,
0-15 ounce; silver, 481 ounces; lead, 41-2 per cent. There is said to be a
shoot 120 feet in length on this vein. :

No. 3 vein is about 600 feet from No. 2; it varies from 1 to 3 feet in
width, and has been opened by a 180-foot shaft with short drifts from the
100 and 150-foot levels. About 100 tons of ore shipped in 1912, taken
mostly from this shaft, is said to have netted about $7,000.

Paragenesis of the Ores. The paragenesis of the ores on the Silver
Standard property also holds good for this property.

North Side.

General Description. The deposits in this locality are associated with
a small boss of granodiorite which has been exposed on the north face of
the mountain (Map 1731). The granodiorite is exposed in the shape of
