ROBERTSON DISTRICT
A DESCRIPTION OF IT'S EXTENT
AND RESOURCES.


the Central Pacific Railroad, in the
Rgan range of mountains, near the
,wn of Ely, the county scat.
The mines of this district we're,
some of them, located as ca as
1859, about tho time of the discoy-
erv of the celebrated White Pine
naming district. They were at first
believed to be silver-lead mines and
were worked for that kind of min
eral. A smelling furnace was erect
ed for the purpose of working the
1fes, and considerable of it was re-
aaced 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
this district it is the Judgment of many
shat 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 sidesof
the canyon contains ore that is valua-
BILE largely in gold and very little
| cad 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
sie,ilar to those on the south side of
the canyon. This is especially true
Of the mines located east Of the Great
Western, while those lying further to
the north and higher on the mountain
are of the silver-lead character. 1t
may be that the gold vein, or the vein
on the south sile Of the canyon is
separated, and forms q spur, or at
this point, becomes wider and extends
further to the north and beyond the
canyon.
Before proceeding further in this
description it will be well 10 state that
tAe ore zone passes through the dis
triet in a north westerly and south
eestsrly direction ana Robinson can
yon cuts through the district in a
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
the lead oullion carried large
amount of gold. Up,n investigation
Il was found that the
AULTMAN MINE
Was furnishing the greater portion of
this valuable metal. 80 The ore of this
mine was of such character that it
could not be reduced rapidly, it being
deeomposed quartz, large portion of
which was clay, which baffled the
most 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
1887, when Messrs. Underhill, Nc
Omie and others secured lease upon
the mine and worked the property for
q number of years. They construct
sd mill of zen stamps capacity and
reduced the orc by crushing and pass
ing the same over copper-silvered
plates. The process was incomplete
and the loss too great to make it prof
liable. Under this lease they devel-
oped large quantities of ore that can
be made profitable by working on a
large scale and with complete mill
lag plant. It would be difficult to
estimate the amount of ore developed
in the Aultman, it not being suffi-
eiently blocked out, but there are
large Quantities of the averaue vo1ue
