and 1930

The holdings of Mayou Gold Copper Company, Limited, consist of the
Mayou group and other claims lying north of Bitter creek about 6 miles
from Bear river.

The mineral deposits are narrow quartz veins in general less than 2 feet
wide, in argillite. At an elevation of 5,300 feet a vein up to 18 inches wide
and mineralized with galena has been followed by an adit for 120 feet.
One hundred feet lower another galena-bearing quartz stringer has been
followed for 130 feet by an adit. There are also chalcopyrite-bearing
quartz veins on the property.

Melvin Group (Locality 95)

and 1929.

The Melvin group is on Marmot river and adjoins and lies north of
the Porter Idaho mine. Two veins occur on the property, one of which
is about 1 foot wide. They contain galena, tetrahedrite, and silver min-
erals and have assayed up to 700 ounces of silver a ton.

Mimico Group (Locality 80)

References: Annual Report of the Minister of Mines, British Columbia, 1922, 1923,
and 1925.

The Mimico group of claims is on the south fork of Glacier creek north
of the Albany group. A quartz vein about a foot wide in argillite, con-
tains pyrite, galena, and sphalerite.

Mobile Group (Locality 89)

References: Annual Report of the Minister of Mines, British Columbia, 1919, 1920,
1921, 1922, 1923, 1927, 1929, 1930, and 1931.

The Mobile group of mineral claims is on the south side of Glacier
creek 3,500 feet above sea-level. The strata on the claims are sediments
overlain by volcanic rocks on the west and intruded by a body of augite
porphyrite on the east.

There are a number of mineral showings on the property, but develop-
ment work has been done mainly on three roughly parallel quartz-sulphide
veins striking north. The main vein has been developed by more than 500
feet of tunnelling and has been traced for 2,000 feet. This vein is in gen-
eral less than 3 feet wide and is mineralized with a great variety of ordin-
ary sulphides and also with several silver minerals whose occurrence ex~-
plains the very high silver content indicated by assays of some samples.
A second vein is up to 8 feet wide. The third vein shows mineralization,
ah aap of sphalerite, over a shattered and sheared zone locally 20
eet wide.
