The L L and H group of claims is on the east side of the lower end of
Bitter Creek glacier. The country rock consists of argillite intruded by
augite porphyrite. There are three fissure zones striking southeast and
dipping northeast. The middle zone is 1,000 feet or more long and up to
12 feet wide. One of the other zones is about 12 feet wide. All are miner-
alized with quartz, arsenopyrite, galena, pyrite, chalcopyrite, and sphalerite.
Development work consists of surface work and crosscut adits. Assays run-
ning several ounces of silver and up to half an ounce in gold have been
obtained.

The holdings of Lakeview Mines, Limited, are at an elevation of 2,000
feet between Glacier and Bitter creeks. The property adjoins and lies east
of the Dunwell. The country rock consists of cherty quartzite and argillite
of the lower part of the Hazelton group intruded by numerous dykes of
quartz diorite, granodiorite, and gabbro. The sediments strike north and
dip west.

The mineral deposit is a quartz-sulphide vein 1 to 4 feet wide that has
been traced by surface and underground workings for 800 feet. The vein .
strikes northwest and dips 60 to 80 degrees southwest. It consists of pyrite,
galena, sphalerite, and tetrahedrite in a gangue of drusy quartz, and contains
small shoots of high-grade silver ore.

A shaft has been sunk on an ore-shoot 3 to 4 feet wide. The portal of
the uppermost of three adits is 500 feet southeast of the shaft. The adit is
60 feet long and exposes in the vein another ore shoot about 3 feet wide. The
portal of the next lower adit is 100 feet below and 275 feet south of the
upper. It is a crosscut for 250 feet, beyond which it follows the vein 300
feet northwestward. This drift is directly below the ore shoot exposed in
the upper adit. The vein in the drift is 6 inches to 3 feet wide and is
locally ore-bearing, but the proportion of sulphide in the vein appears lower
than in the vein in the upper adit. The lowest adit begins as a crosscut
800 feet southwest of and 250 feet below the shaft. It enters the vein 750
feet from the portal, and follows it as a drift for 175 feet. The adit enters
the vein directly at a point lying down the dip from the ore shoot exposed
at the shaft. The vein at this level consists of drusy quartz very sparsely
mineralized with sulphide.

A total of five tons of ore shipped in 1913 and 1914 averaged about 0°4
ounce gold and 400 ounces silver a ton.
