GEDDES d d.
A Report on the Outlook and Pres.
ent Workings of This Mine.

ent workings OF This Mine.
A SENTINEL reporter recently paid a visi.
to the Geddes & Bertrand mine at Score
Canyon. The mill has been fully described
heretofore. and III reporter now gives 6
complete description Of the mine. There
are at present about 40 miners employed
and go mill hands. Last month about So
tons OF dry ore was worked per day in the
mill. During the frosty snap, when the
water pipes were frozen, a suficiency Of
water was obtained by melting the snow
Mr.. Atchison, the foreman, conducted the
reporter through the mine. The machin.
cry, which runs beautifully, under the
able engineering Of E. r. Dennison, low
cred them down the vertical shaft to the
lower level, which is 800 feet from the sur
face. The shaft on the incline is 500 feet
to the same level. The ore dips at an angle
Of 40 degrees from the main shaft, and is
principally antimonial silver. At the
bottom of the shaft the old Geddes & Ber-
trand Company ran o drift under the ore,
and consequently missed it, but the pres
emit management bringing more practical
knowledge to bear upon the subject, fol-
lowed the ore successfully, as the mill re-
turns fully show. The air throughout the
mine is exceedingly good, for there are
three connections from the outside with
the main shaft. This, combined with the
fact that there is scarcely a stick Of tim
Der needed to support the workings, re-
duces expenses very considerably, and
makes this mine one Of the most pleasant
in the State for working in. A short dis.
lance from the shaft, on the $40 level, is a
porphyry dyke, on which the ore was found
in fair quantities. This dyke was followed
and a track laid upon it for the distance
Of 40 feet, until the ~porphyry swelled and
raised the track to the roof, arresting for
the time all further developments.
Continuing through the tunnel large
porphyry dykes or beds are met with, and
at the end Of it the porphyry rises to the
east at an angle Of about so degrees, the
seam being from q north to south direc-
ton. Ascending the ladder by the side of
the 800 chute a small chamber is reached,
from which large quantities Of good ore
have been extracted. This chamber is the
lowest of a series which ascend gradually,
and behind to within 25 feet of the surface.
This is as high as the management deems
it wise to work, as the hosting works are
built just above these series Of chambers.
From this chamber a tunnel is being
driven. About 40 feet from the chute
there is a break in the ore body. The
theory of the management is that the
quartz wall which constitutes one side of
the break has thrust the ore body to the
east. The break is being cut through,
and sharp prospecting work will soon be
carried IN. The indications are that a
most valuable body Of ore will be found
on the other side Of the break.
A tunnel is also being driven under the
porphyry, in anticipation of finding q good
ore vein underneath, although so far the
upper ledge is the best. The upper ledge,
as at present developed, is $50 feet wide,
and the indications are that it is very
much wider.
Ascending a rugged path (no steps or
ladders are required) n chamber after
another is reached. Indeed, the mine is
one series Of chambers from the head of
800 chute to whiting 25 feet Of the surface.
In the upper chambers streaks of rich
black metal are found, assaying 175 ounces
of silver to the ton. All through the
mine looks we'll. The miners speak in the
most iattering terms of the prospects, and
ere long we expect to see the Geddes &
rank as one of the steadiest, if
the foremost, bullion producers Of the
neighborhood. To save the trouble of
the ore a tunnel is being cut,
from the mill to the mine. 1t is
now well on the way, and ere long will be
fully completed.
