NORTH-WESTERN DISTRICT (No. 1). 51

constructed from the beach to the mine, has been brought to a successful culmination and now
gives excellent transportation facilities for Supplies and ore, and also gives electrical power at
the mine. A 1,200-foot compressor, electrically driven, has been installed at the mine and
furnishes the power for mining not only at Porter-Idaho, but also at Prosperity. No ore has
been shipped from Porter-Idaho during the year.”

This group is also being operated by the Premier Gold Mining Company. The

Prosperity. following information concerning the 1929 operation has kindly been supplied

by D. L. Pitt, manager: “A vigorous development campaign was carried on
during the entire year, pushing out drifts along indicated ore-zones and generally preparing the
mine for production. With the completion of the Porter-Idaho tramway a method of trans-
porting Prosperity ore was provided, and, by a mutual arrangement between these two com-
panies, Prosperity ore is being handled over the Porter-Idaho tramway.

“In November Prosperity came into production and during the months of Noyember and
December some 1,650 tons of ore was shipped. According to our local sampling, the estimated
content of this ore will be: Gold, 32 0z.; silver, 109,000 oz.

“At the mine proper various surface improvements were made, such as the completion of
the bunk-house, which is now a modern steam-heated, electric-lighted building; a new ware-
house, dry-house, and blacksmith-shop were built, and the proper snoyw-sheds and covered
runways provided to ensure operation without interference from the snow during the winter.”

This company was formed with a capital of 500,000 shares at $1 each, 29,000

Melvin Mining of which are under option to the Marmot Metals Mining Company. The

Co., Ltd.* property, which consists of one claim and four fractions—Melvin and Melvin

Fractions 1 to 4—is Crown-granted and registered in the name of the company.

It is situated above the glacier at the head of the North fork of the Marmot river and to the
east of and adjoining the Prosperity group.

The main working consists of a drift which has been driven for 40 feet on a high-grade
stringer in a shear-zone in a country-rock consisting of volcanic tuffs and breccias. The stringer,
which strikes N. 20° W. and dips very steeply to the south-west, is well mineralized with native
silver, galena, zinc-blende, pyrite, and chalcopyrite.

A winze was started at a point about 20 feet in from the tunnel portal, which at the time
of my visit was down 7 feet. A width of 26 inches of well-mineralized vein-matter was exposed
in the bottom and some more left on the hanging-wall.

A chip sample over 14 inches of vein-matter next the foot-wall in the bottom of winze
assayed: Gold, 0.06 oz. to the ton; silver, 2 oz. to the ton; lead, trace; zine, 7 per cent. A chip
sample over the next 12 inches of vein-matter assayed: Gold, 0.02 oz. to the ton; silver, 5.5 oz.
to the ton; lead, trace; zinc, 7 per cent.

The property of this syndicate is situated on the north shore of the mountain

Bi-Metallic overlooking the Marmot river and almost opposite the mouth of the North fork,

Syndicate.* The group consists of the following claims: Stimulator 1 to 4, Northern Slope,

Northern Slope No. 1, Gold Pan, South Slope, South Slope No. 1 and No. 2,
and Moonlight. The syndicate is composed of Clay Porter, W. C. Blanton, C. W. Magee, and
A. R. Casey.

The property is about 3 miles from tide-water and is reached by a fair horse-trail which
has been constructed from the main Marmot River trail to a point about two-thirds up the hill,
and then continues as a very steep foot-trail the rest of the way. Work is being done from a
tent camp just on timber-line, at an elevation of 8,900 feet.

Several yeins are being developed, which appear to be shear-zones occurring in granite.

The Panhandle yein, which strikes S. 10° E. and dips 75° east, varies in width from 2 to 6 inches.
It carries visible gold and some pyrite and has been traced for some distance by open-cuts.
A sample across 6 inches of quartz exposed in an open-cut assayed: Gold, 0.24 oz. to the ton;
silver, 8 oz. to the ton. A drift has been put in for a distance of 18 feet on the Gold Pan vein.
Six inches of quartz has been left standing on the hanging-wall. A sample over 18 inches of
mineralized vein-matter under the quartz assayed: Gold, 0.08 oz. to the ton; silver, 0.24 oz.
to the ton. A sample over 6 inches of mineralized quartz at the portal of the drift assayed:
Gold. 0.34 0z. to the ton; silver, 17.5 oz. to the ton. This vein has also been traced for several
hundred feet. Its strike is S. 50° W. and dip 40° north.
