At elevation 5,150 feet, two narrow fissures in granodiorite are
prospected by a short adit and two open-cuts. The fissures carry up to
2 inches of rusty cellular gouge, but contain no sulphides. A sheared zone
1 foot wide occurs in the granodiorite several hundred feet farther up the
slope. In an open-cut at elevation 5,500 feet this sheared zone is rust
“stained and holds much chlorite, but is otherwise barren. Both the fissures
and sheared zone strike north 30 degrees west and dip from 55 to 75
degrees southwest.

A narrow, mineralized zone has been followed down the southeast
side of the peak of Mount Evelyn between elevations of 6,600 feet and
6,475 feet by a short adit and several open-cuts. The zone occurs in
fine-grained granodiorite along a fault that strikes north 10 degrees west
and dips 60 degrees southwest. It is narrow, seldom exceeding 2 inches
in width, and in places pinches to a fraction of an inch. It consists of
altered rock replaced by considerable tetrahedrite. This is evidently the
occurrence irom which 2 tons of ore was shipped in 1913.

Last Chance Claim (44)

The Last Chance claim is on the north side of the pass at the head of
Toboggan Creek, 8 miles northwest of Smithers. The workings are at an
elevation of 5,150 feet, a few hundred feet above the tractor road to the
Silver Creek group. The property was held for several years by O. Hanson
and J. Sealey.

Several, small, irregular sulphide veins in andesite have been
prospected by open-cuts and a short adit. The veins are composed largely
of magnetite, with considerable pyrite and a little chalcopyrite.

Three of the sulphide veins are exposed in a shallow open-cut 60 feet
long. They occupy fractures that strike from north 55 to north 70 degrees
west and dip steeply north. One vein at the east end of the cut is 20 feet
long and ranges from 1 to 12 inches in width. Near the west end of the
cut, two veins lie parallel, one 20 feet long with an average width of
6 inches, the other 6 feet long and 3 inches wide. All three veins terminate
against small cross faults. The andesite wall-rock is somewhat altered,
but is only sparsely mineralized,

About 100 feet farther west another vein outcrop is opened up by a
small open-cut. This vein is 30 feet long and ranges from 3 to 12 inches
in width. It strikes north 55 degrees west and dips 85 degrees northeast.
The vein consists of massive magnetite and pyrite cut by small chalcopyrite
stringers. A selected sample of this vein, collected by D. Lay in 1926,
assayed: gold, a trace; silver, 2 ounces a ton; copper, 2:5 per cent. At the
foot of a bluff 20 feet below the vein outcrop, an adit driven 75 feet along
a bearing of north 20 degrees east fails to disclose any mineralization of
importance. A representative sample of a small amount of vein material
collected from the dump assayed: gold, 0-02 ounce a ton; silver, 0-09
ounce a ton; copper, 3-75 per cent; zine, 0-16 per cent.
