About 20 feet to the east of the shaft-vein a series of open-cuts traces another
parallel vein whose maximum width is 4% feet. A 160-foot length of vein up to 4%
feet wide is separated on the south by 110 feet from a 50-foot length of vein, maximum
width 18 inches. Whether it is a single vein 320 feet long or two shorter separate ones
is not known. This vein is in places only sparingly mineralized with pyrite.

In 1883 the Burns Mountain Quartz Mining Company, at an elevation of 5,366 feet
on the north-east side of Burns Mountain, began driving a crosscut almost due south
to explore, at a depth of about 170 feet, the downward extension of the veins exposed
on the surface. It is evident from Bowman’s map and from the apparent direction of
the drive that the crosscut was headed for a point almost directly beneath the shaft.

In 1884 it is recorded* “that the Burns Mountain Quartz Mining Co. indeed pushed
ahead their tunnel to a point where it was expected the ledge would be found, but,
failing to strike which, the work was suddenly stopped for some time.” They shortly
after resumed operations.

In 1886 it is recorded+ that ‘the Burns Mountain Quartz Mining Company have
during a great part of the season had men under charge of Mr. Jacques, of Victoria,
at work running drives in search of the main lode, but of the result of their labour I am
not informed further than that they have now driven in over 800 feet. Aisi

In 18874 “the Burns Mountain Co. has done but little this season to further prove
their mine.”

Evidently the underground work did not encounter any veins comparable in width
to those exposed on the surface, for no mention of further work on the property is
recorded. Moreover, the dump at the portal of the crosscut contains little or no vein
quartz. The crosscut is now caved and inaccessible.

Company office, 640 Pender Street West, Vancouver, B.C. The com-
Foster Ledge pany owns thirty-four Crown-granted mineral claims (Lots 10427 to
Gold Mines, 10435, 1664 to 1680, 1688, 7723 and 7724, and 8895 to 8899) extending
Ltd. (9, 10, south-westward from the head of Chisholm Creek across Oregon Gulch
Il, and 12). to Davis Creek. A number of quartz veins were found on Oregon
Gulch during the 1870’s. The Foster Ledge, near the junction of the
west branch of Oregon Gulch, yielded some high gold assays, and in 1877 a shaft was
sunk on it. Shortly after, an adit was driven northward just above the junction of
the west branch of Oregon Gulch. A little additional work was done before Foster
Ledge Gold Mines, Limited, acquired the claims in 1933. Since then, two other adits
have been driven and some work done in the old adit near the Foster Ledge.

The company built a camp on the lower part of Oregon Gulch about 1,000 feet from
the highway and a little more than a mile north-east of Stanley.

The claims are underlain by grey micaceous quartzites of varying fissility, black
argillaceous quartzite, some highly ankeritized quartzite schist, and grey quartzites that
strike north to north 15 degrees west and dip 25 to 40 degrees east. The Last Chance-
Nelson Creek fault runs in a northerly direction through the eastern half of Lot 1666,
crosses the west branch of Oregon Gulch about 1,000 feet from the Foster Ledge, and
runs through the western part of Lot 10481. Another fault, which may be fairly large,
runs northward through the western part of Lot 8897 and was encountered in the
underground workings there.

The showings (see Fig. 5) comprise the Foster Ledges explored by an old shaft,
adit, and surface stripping on Oregon Gulch on the eastern side of Lot 10427, a vein
formerly exposed in three open-cuts in the south-west corner of Lot 1664, a narrow vein
exposed in an adit on the east side of Oregon Gulch in the eastern half of Lot 10435,
and several narrow veins exposed in the adit in the western half of Lot 8897.
