The Mines of Colorado - 1867
Spring while the snows are melting and there is an
immeasurable surplus of water, thus not robbing the
lower Fall River country of its natural stream.
Then, if mining should become a separate branch
of business from the treatment of the ores, as it np
doubt ought and will, these powers to be used for
hoisting, crushing, and dressing, the ore to be taken
to the coal-beds at the base of the Mountains for
treatment, or the coal to be brought up, either of
which would nearly dispense with the use of wood-
fuel. But it would necessitate the construction of
a railway from Black Hawk via Clear Creek Kan-
yon to Golden City. A careful survey has demon-
strated the entire practicability of this project, the
grade, with three tunnels — aggregate length, 3000
feet — averaging about 100 feet per mile for the dis-
tance, twenty-one miles. In view of the benefits
that would result from their completion, these great
enterprises are the most feasible of any we know of.
The prospect is that the consumption of fuel will
go on increasing until there will be no escape from
one or the other or both of them.
It is within a radius of one and a half miles from
Central City that all the lodes and improvements
mentioned hereafter in this chapter, occur. Tum-
bled headlong into so small a compass are Bobtail,
Bates, Gregory, Mammoth, Quartz, Casto, and Gold
Hills, with their complicated net-work of rich veins,
to say nothing of as many more with no special
names. The outlying districts of the county, and
there are some, must be consigned to a separate
chapter. For precise information with regard to the boundaries, streams, towns, and topography of
the county, the reader is referred to an accurate
map on a large scale, delineated from careful sur-
veys by Messrs. Morse & Hill of Central City. The
examination of the mines of Gilpin County, a re-
port of which follows, was made in August 1866,
by the writer in person.
The Black Hawk Gold Mining Company have 500
feet on the Gregory, being No's 1, 2, 3, 16 and 17
west ; 200 on the Foot & Simmons, 250 on the
Gregory Extension, 76 on the Bobtail, and a great
deal of less developed mining property. It is with
that which is productive we have to do. They are
working 1, 2 and 3 on the Gregory, running a level
380 feet from the surface. The first level is the
bottom of the old mine, and is about 300 feet from the
surface. Above that there is still much virgin ground.
The lower level will soon be finished, exposing
ground nearly 100 feet deep by 300 long, and in all
probability two crevices, the entire length, from five
to fifteen feet apart. These will doubtless come
together at a greater depth. The Gregory main
crevice varies in width from two to four feet ; the
other crevice is perhaps half as large. The work-
ing shaft is on No. 2, and is strongly timbered. A
six-inch pump removes the water from the entire
mine. On No. 1 there is also a shaft, now 330 feet
deep, opening on the surface in a 20-stamp mill.
The hoisting and pumping are done by a 1 so-horse
7 engine, which also furnishes motive power for the
mill. The Foot & Simmons mine shows an aver-
age crevice a foot in width, is run by the Consoli-
dated Gregory engine adjoining, and is in very good
shape, worked by regular levels, the first two of
which are exhausted ; the third, at a depth of 260
feet, now furnishing stoping ground. The main
shaft is being carried down in time for the fourth
level. Dump cars convey the ore to the shaft on
tramways, there is little or no water in the mine,
and it is worked very economically* In the Bob-
tail mine, operations are suspended for want of a
pump. The last work done was excavating a level
400 feet from the surface, and taking out the back.
In the floor a crevice is exposed for 64 feet, three
feet wide — nearly half of it pure ore. There is a
large engine-house, with a 40-horse engine, on the
Bobtail mine. On Gregory 16 and 17, there are
shafts 60 and 90 feet deep respectively, both of
them on good veins of ore. Nothing has been
done on them for two or three years. On the
Gregory Extension a shaft has been sunk 285 feet,
and a level run near the bottom in either direction
40 or 50 feet. The crevice is yet rather pinched,
the ore badly mixed with poor rock.f The mine
furnishes just enough water to rtfn the hoisting en-
gine. A wooden railway and car convey the ore
300 yards to the mill in Black. Hawk. The Company have a large, frame, stamp-mill in the heart of
Black Hawk — sixty 88o-lb. stamps. The crushed
material runs over short stationary copper plates
on to shaking tables of the Keith pattern, whence
it passes into Cornish buddies for concentration.
The engine is 150-horse, and is supplied with water
froih North Clear Creek, which passes between the
engine-house and mill. A steam pump and suffi-
cient hose provide reasonable guarantee against
accidents by fire. This mill and that on the
Gregory have produced during the Summer not far
from $3,000 a week. The Company have twenty
stamps not yet set up, and a large amount of min-
ing supplies. It is at present under the manage-
ment, in Colorado, of W. L. Lee, one of the original
owners, still a very large stockholder, and an in-
comparable business man.
