ore shoots. Six tons of ore shipped in 1925 ran 260 ounces in silver a ton,
3 per cent lead, and 23 per cent zinc. The shear zone in which the vein lies
is several times as wide as the vein and has not been thoroughly explored.
Two parallel quartz-barite veins, each more than 10 feet wide, contain
disseminated galena. They outcrop a short distance above the workings,
but have not been exploited. Several, small, rusty areas visible near the
shaft are local concentrations of pyrite and pyrrhotite in a bed of tuff.

The claims of the Tyee group are at an elevation of 500 feet on the
east side of Bear river between Glacier and Bitter creeks. The country rock
is a stock of granodiorite that intrudes volcanic rocks. A quartz vein 1 to 5
feet wide and 75 feet long is exposed by a shaft and open-cuts. The vein
strikes northwest, is vertical, and consists of quartz and sulphides in
approximately equal amounts by volume. The sulphide is chiefly pyrite,
but some chalcopyrite is present. A crosscut adit 60 feet below the vein-
outcrop has not been driven far enough to reach the vein. The vein matter
locally assays several dollars a ton in gold.

Union Silver Mines, Limited, was organized in 1925 and acquired the
Last Chance group of claims on the north fork of Glacier creek. This group
adjoins and lies west of the Columbia group. An adit has been driven 95
feet in augite porphyrite to develop a quartz vein that proved to be barren.

The United Empire Gold and Silver Mining Company, Limited, holds
the Gold Cliff group of mineral claims. These lie on the eastern slope of
mount Dolly near Stewart and adjoin the holdings of the Bayview Mining
Company, Limited. The lowest mineral showings are at an elevation of
about 3,000 feet. A vein is exposed at this place striking northwest and
dipping 45 degrees southwest. It is 1 to 3 feet wide and has been traced
by open-cuts for 200 feet. It lies partly in granodiorite, partly in volcanic
rocks, and makes a right angle with the edge of the batholith. Seventy
feet above and 70 feet west of the upper exposure of this vein is another
vein parallel in strike but dipping steeply southwest. This vein is 1 to 4
feet wide and has been traced up the hillside for 500 feet. These veins con-
sist of galena, sphalerite, pyrite, and tetrahedrite in a gangue of quartz.
They are very well mineralized on the surface and in some places are prac-
