LAKE SUPERIOR COPPER
MINES.

nal, for the information of our readers, some Of
whom are interested, we suppose, in the compa-
ny alluded to. 1t is to be remembered that uc-
counts of Lake Superior mines are to be receiv-
ed with caution, especially where stock is to be
sold before the mines have been thoroughly work.
ed. BY the charter OF this Company, the ores
produced are to be manufactured in this state
St Johnsbury, Caledonia County.
AMERICAN ExpLoRINe, MINING AND MANU-
FEATURING COMPANY The American Explor-
ing, Mining and Manufacturing Company was
incorporated by the Legislature of Vermont, No
vember, 1916, with capital of one hundred
thousand dollars. The object of the Company
is to explore in Vermont and in other States and
Territories of the United States, for mines of
useful and precious metals, and to work
such of the mines as may be discovered by their |
agents, either on the sole account of the Compa
ny or in connection with Others The extraordI-
nary discoveries made in the region of country
bordering on Lake Superior, induced the direc.
tors 10 send large exploring force to that re-
gion. This force, consisting of nearly one hun
dred men, including engineers, miners packmen
and voyageurs, left Detroit on the 18th of Nav,
1916, under the command of Col. Samuel Peck
of Sault dc st. Marie. The force WINS divided
into seven parties, consisting each of one chief
and two assistant engineers, and such number of
packmen and miners as each party required. All
the parties were supplied with provisions for five
months. To insure thorough exploration. tho
country bordering on the south and west of Lake
Superior was divided into seven districts and
one district assigned to each party. All the par
lies were landed IN the respective districts be-
fore the 10th of June, and commenced explora
ton upon the Lake shore, and, thence south. in
the State Of Michigan, and in the Territory of
Wisconsin. The parties were in the field about
four months, during which time thew made mn
examination OF great portion of the country.
over one hundred miles south of Lake Superior'
and between Lake Michigan on the east. and ST.
CrolX River, and It's branches, on the west. The
exploration resulted in the discovery of large
number OF copper, silver apd iron mines. In Au.
gust party under charge of the chief engineer
Of party No. 6, was sent to Isle ROYAL. and dis
covered number of valuable copper, and COP
per and silver mines. By the laws passed at the
last session of Congress for the sale of Mineral
lands in Michigan and Wisconsin, the right of
pre-en.ption to all the mines discovered by the
engineers and agents of this Company in Wis.
consln, Michigan, and upon Isle Royal, is vested
in this Company.
Among the copper mines now occupied by the
Company, are two of yellow sulphuret of copper,
similar in appearance and character to the yell
low ore, found in the English Cornwall mines,
three OF gray suphuret, one of gray sulphuret
and silver, two Of native silver and copper inter-
mixed, and others of native copper found in spar,
epldote, laminate, amigdaloid trap rock. All the
ore and most THE native copper occurs in veins.
All the mines discovered by the parties, ore with
In sixteen miles of the Lake shore, and many of
them in the immediate vicinity of the Lake.
1t is the intention of The Company to proceed
with the working of these mines with all reason
able despatch, having due regard to economy
Experience thus far has shown that in openings
new mine, too much "haste makes waste" In
tit the position of the vein is well ascertaned,
but few miners can be employed TO advantage.
The experience gained in one mine is of great
advantage IN opening succeeding mines and ev-
cry new discovery ofthe peculiarlties of the gen.
eTal formation of the country, and the peculiar
position of the veins, adds to the experience Of
the miner, and enables him to open succeeding
mines at less expense.
I This consideration has induced the directors
to adopt the plan ofopening, in the first instance,
but five mines, viz: the Burlington, Norwich,
Clifton, Brunswick and Montpelier. AS these
mines are of different character and embrace
the various descriptions ofore and native copper
found in the country, it is presumed the opening
of them will add much TO the stock of present
information, and make saving of expense in fu-
ture operations.
The immediate working of all the mines dis.
covered by the Company will involve a larger
expenditure of money than was originally con-
templated by the ST ockhoders of the exploring
Company, and renders 1t desirable to enlist the
aid of other interests, in the prosecution OF min
ing operations. This consideration has induced
the adoption of the plan to sell portion of the
interest IN each mine, at price but little excee-
ding the cost of exploration, and probably less
than 1t would cost any Company or individual to
send an exploring party into the country 10 dis
cover mines
The rich specimens found upon the surface
the extent Of the vens-and the great produc-
tiveness of the ores found, render it more than
probable that the working of the mines will yield
an amount of profit sufficient TO satisfy the rea-
fsonab!e desire of very large number of propri-
etors. Taking into consideration the fact that
some, and perhaps all these mines may prove as
valuable as any Of the mines of Lake Superior,
II is not improbable the prices will advance as
the Developments at the mines Increase the con-
hdence of the public in their productiyeness.
The following description Of the five mines, is
from the Field Books, and reports of the explor-
ing engineers, and may be relied upon as cor
rect.
burlington Mine. The vein is we'll defined,
and can be traced upon the surface for several
rods The ore is yellow suphuret, simil ar to the
ore of the English Cornwall mines IL is on the
north blut OF hill, 20 or so feet high. The
: vein IS about one-third OF the way up the hill
uio'ohSc mum the Luxe, ABOUT sixteen miles,
The specimens were taken from the vein. The
location of this mine s directly south from HUI
ron River
.Nor,oich Mine. This mine is about 10 miles
! from the Lake, ard miles from navigahle wa
ter. The metal is native copper and silver, found
, in veins, quartz and spar. The vein is regular
and well defined, varying from IL TO "a inches
wide; lies rear the top, and runs parallel TO the
} face Of a cliff OF tap rock estimated at five hun
bred feet high. The vein has been traced upon
the location nearly half mile. 1t dips into the
cliff at an angle Of forty-fve degrees. The speci-
mems were dug out with pick. This mine, in
J appearance of vein and copper, resembles the
Cliff mine of the Pittsburgh Company. This
mine is located south of the mouth of the On
tonogon River.
Clifton Mine. This mine is two miles from
the Lake, on branch OF Black River. The vein
is of spar, well defined, about two feet wide, with
good mineral indications. The specimens were
taken from a single blast. There are four veins
on the location.
Brunswick Nine Is situated eight and half
miles from the Lake, and about 90 miles below
Foud du Lac, on the south shore of the Lake.
The country from the Lake is generally level for
eight miles. The vein is about fifteen inches
wide, and contains much copper ore yellow sui
phuret) On the west side of the stream, the
