to this property and others on Maroon mountain. There are two log cabins
at an elevation of about 4,300 feet just above timber-line. In 1923 the
claim was under bond to O. P. Brown of Seattle who operated a small
Ross gold mill for a short time. It passed into the hands of the Chiro
Mining Company in 1924, but nothing was done, and in 1925 the Hopper-
Davis Syndicate took it over, drove a crosscut adit 143 feet long, and
drifted 65 feet on a narrow, gold-quartz vein. The prospect has since
lain idle.

The Bear claim is underlain by slate and sandstone and a bed of
conglomerate that varies in thickness from 120 to 160 feet and increases
northeast to 240 feet on the adjoining Gold Cap claim. The conglomerate is
overlain and underlain by the slate and sandstone. It strikes northeasterly
and dips southeast at angles varying between 50 and 75 degrees. Pebbles
of quartzite, argillite, and granite are numerous in the conglomerate and
average from 1 to 4 inches in diameter. The sediments belong to the
Hazelton group of Jurassic age.

The quartz vein on the property is known as the Bear vein. It dips
southeast at angles of 50 to 70 degrees and lies in a shear zone that for
the most part parallels the bedding of the slates and sandstones in which
it is developed, but in places cuts across the bedding planes at small
angles for short distances. The vein lies to the west of and below the con-
glomerate bed.

An aplite dyke crosses and recrosses the Bear vein. It can be followed
for more than 3,000 feet southwest to a small lake on the Black Wolf claim.
It ranges from 4 feet wide near its ends to 12 feet wide along its central
part.

The best outcrops of the Bear vein are a few feet above what is known
as the upper adit. For about 50 feet the vein maintains an average width
of 3 feet. It consists of much pyrrhotite with sphalerite, chalcopyrite,
pyrite, and galena in a quartz gangue. South from the adit the vein
narrows to 6 inches in a short distance and within 200 feet it pinches out.
Northeastward from the vein and aplite dyke intersection near the adit,
the vein narrows and maintains an average width of less than one foot.
About 700 feet to the northeast an adit was driven south along the vein for
35 feet. For this distance it ranges from 3 to 6 inches in width and is
sparsely mineralized. A short distance farther southwest the vein is
exposed along the surface for over 100 feet and has widths up to 18 inches
of white quartz, some of it honeycombed through oxidation of pyrite.

The upper tunnel, driven east 26 feet, intersects the vein about 15 feet
below its outcrop. There is a drift 5 feet each way on the vein and a
miniature stope extends to the surface. A sample taken from the north
face of the drift by H. T. James in 1928 assayed: gold, 1-26 ounces a
ton; silver, 35 ounces a ton; lead, 6 per cent; zinc, 4 per cent. A repre-
sentative sample from the south drift collected last summer assayed 0-16
ounce a ton in gold and 0-64 ounce a ton in silver.

The lower adit, about 85 feet below the upper one, was driven 150 feet
east to the vein and drifts run 25 feet south and 39 feet north. In the south
face the vein is only 4 inches wide, at the intersection of the crosscut adit
