RoEIgsON MINING DISTRICT
A DESCRIPTION Or IT'S EXTENT
AND RESOURCES.

ShHO
the Contra! Pacific Railroad, in the
Eyan range of mountains, near the
t)wn of Ely, the county seat.
The mines of this district were,
some of them, located as early as
1889, about the time of the discov-
cry of the celebrated White Pine
mining district. They were at first
believed to be silver-lead mines and
were worked for that kind of min
sral. A smelling furnace was erect
cd for the purpose of working the
ores, and considerable of it was re-
duced in that way, but at that early
day smelling had not got to that de-
gree Of perfection that it has since
attained, and this process was aban-
doned.
From the surface indications and
the distinct character of ore found in
shis district it is the Judgment of many
that there are two ore veins that are
separated by Robinson canyon. The
vein on the north side of the canyon
contains ore that is valuable largely
In silver, lead and very little gold,
while the vein on the south side OF
the canyon contains ore that is valua-
bic largely in gold and very little
lead and silver. This is not the case
In each instance as the mines that are
situated next to the canyon on the
north side are, some of them, very
4milar to those on the south side OF
the CANYON. This is especially trne
of the mines located east of the Grea5
Western, while those lying further to
the north and higher on the mountain
are of the slver-lead character. Il
may be that the gold vein, Of the vein
on the south SIDE Of Tie canyon is
separated, and forms = spar, Or at
this point, becomes widg1 and extends
further to the north AID beyond She
canyon.
Before proceedina further in this
description it will b3 well TO state taa5
ths ore zone passes through the dis
trict in nortll-westorly &nd south
sastorly direction ana Robinson ear
yon cuts through tho district in q
south-easterly course near the middle
Of the ore zone.
Returning again to the work done
In the early days OF the district, while
they were prospecting chiefly FOR sill
YER and lead it was discovered that
ahe lead bullion carried q large
aMount Of gold. Upon investigation
% was found that the
AULTMAH MI8a
Was furnishing the greater portion Of
shis valuable metal. The ore Of this
mine was of such character that it
could not be reduced rapidly, it being
dseomposed quartz, a large portion Of
which was clay, which bafiled the
nost experienced smelters of the
camp. 1t was at last concluded to
abandon this mine so far as smelling
ore was concerned; they however
worked the property IN pursuit of
lead, which was not found in paying
quantities, but they did develop a
large vein of ore carrying gold. The
Mine was left in this condition until
1897, when Messrs. Underhill, Nc
Omie and others secured lease upon
the mine and worked the property for
number of years. They construct
ed mill of ten stamps capacity and
reduced the ore by crushing and pass
Ing the same over coppersilvered
plates. The process was incomplete
and the loss too great to make it prof
table. Under this lease they deyel-
oped large quantities of ore that can
be made profitable by working on a
large scale and with a complete mill
ing plant. 1t would be difficult to
estimate the amount of ore developed
IN the Aultman, it not being sufi-
