A third quartz vein is exposed in the face of a 60-foot bluff of inter-
bedded, gently dipping argillite and tuff about 300 feet east of the last-
mentioned vein. The vein is 10 inches wide, strikes easterly, and has a
vertical dip. It contains from 1 to 2 per cent of a galena and pyrite. An
assay of a tpyical sample of the vein quartz gave: gold, a trace; silver, 0-30
ounce a ton. What may be a continuation of this same vein was seen
several hundred feet farther east at elevation 5,100 feet, where a quartz
vein of 15 inches average width is exposed for 30 feet near a group of claim
posts. The vein carries a little pyrite and galena. A chip sample across
the vein assayed: gold, a trace; silver, 0:40 ounce a ton.

Farther southeast, at elevation 5,200 feet on the Bingo claim, a quartz
vein 6 feet wide has been stripped for about 40 feet. Its continuation is
heavily drift covered. A typical sample of the vein quartz, carrying 1
per cent of pyrite, gave on assay: gold, none; silver, a trace.

Another quartz vein occurs at an elevation of 5,650 feet on the divide
looking down into the valley of the middle fork of Lorne creek. The vein
is exposed for less than 100 feet, its continuation down the steep middle
fork slope being ice covered. It occurs in argillites and interbedded tufts
which strike south 50 degrees east and dip 27 degrees southwest. The
sediments are intruded immediately northwest of the divide by a stock-like
body of granodiorite, several hundred feet in diameter. A representative
sample of the vein quartz gave on assay: gold, a trace; silver, 0-32 ounce
a ton.

The owner reports that another vein not seen by the writer occurs
wholly in granodiorite some distance above the first-described occurrence.
It is said to be covered by snow most of the year.

September and July Groups (35, 36)

The July group of two claims and September group of four claims
occupy the wide valley between Goat mountain and mount Couture, at the
headwaters of the north fork of Lorne creek. August Johnson, the owner,
has constructed a 15-mile pack-horse trail west from Ritchie. station to a
cabin on the south side of the valley which acts as base camp for work on
the Bermaline, July, and September groups.

On the September claim three quartz veins are exposed in the bed
of a small mountain stream at elevation 4,000 feet, near the junction of
the stream with Lorne creek. The veins range from 6 inches to 8 feet in
width, lie roughly 50 feet apart, strike north, and dip from 50 to 70 degrees
east. The country rock is comprised of thick beds of volcanic tuffs which
dip gently. There is much drift cover and the veins are exposed for less
than 100 feet along their strike. The vein quartz carries about 1 per cent
of pyrite. Two channel samples collected by the writer gave on assay less
than half an ounce of silver a ton and no gold.

On the July claim, on the Goat Mountain slope of the valley, three
narrow quartz veins lying 15 feet apart have been stripped over an area
50 feet in diameter. The veins occur in massive tuff beds which strike
south 60 degrees east and dip 10 degrees north. The individual veins range
from 3 to 6 inches in width and carry pyrite and chalcopyrite in small
