northerly strike and its dip is reversed to southwest. Vein formation on
the east side of the stream was evidently dependant upon both dyke and
tracture zone following the same path. Since they are known to diverge on
the west side of the creek, it follows that any future prospecting should be
done on the east side of the creek along the strike of the dyke. A thick drift
cover hinders trenching.

The Martin claims are 6 miles west of the north end of Kitsumgallum
lake. A good pack-horse trail leaves the lake just below the mouth of
Beaver river, leads west 3 miles to Little Beaver river, follows the north
side of the river for 3 miles, and then climbs steeply from 1,500 feet above
sea-level to 2,500 feet by a series of switchbacks to the properly.

A narrow quartz vein heavily mineralized with sulphides occurs along
a fault in grey, coarse-grained granodiorite at an elevation of 2,550 feet.
The granodiorite extends down the mountain side to the river, but 50 feet
above the vein is in contact with overlying intruded sediments, chiefly
greywacke and argillaceous quartzite. A second parallel vein occurs in the
sediments 125 feet above the main vein.

The main vein strikes north 40 degrees east magnetic and dips 55
degrees northwest. Its average width is 12 inches and the maximum width
about 18 inches. Four large rock trenches expose the vein at regular
intervals for a little over 300 feet. A channel sample taken across 12
inches of quartz in the southwesternmost pit assayed a trace of silver and
0-02 ounce of gold a ton. Sixty-five feet farther northeast in the second
pit the vein is heavily mineralized with massive pyrrhotite cut by small
galena stringers. A channel sample 7 inches long across the vein in this
pit assayed: silver, 5:04 ounces a ton; gold, 0-16 ounce a ton. In the
remaining two pits the vein contains a high proportion of galena, some
arsenopyrite and sphalerite, but almost no pyrrhotite. Seventy-five feet
below the vein a crosscut adit was driven northwest. The vein was inter-
sected 230 feet from the entrance and consisted of only a few inches of
barren quartz. The adit was continued an additional 45 feet, but no other
veins were encountered.

The second vein is exposed for only a few feet by natural agencies
between two large trees. The vein is 75 feet above the contact of the
sediments and granodiorite and is enclosed in greywacke which strikes from
80 to 90 degrees northeast and dips 50 degrees north. The vein strikes
north 40 degrees east and dips 42 degrees northwest. It is 7 inches wide,
and is about 75 per cent solid arsenopyrite and 25 per cent quartz. A
channel sample across it assayed: gold, 0-20 ounce a ton; silver, 0-36 ounce
a ton; arsenic, 14-44 per cent. This occurrence suggests the desirability of
searching for other veins in the sediments.
