ROBINSON MINING DISTRICT.
A DESCRIPTION OF ITS EXTENT
AND RESOURCES.

one hundred and fifty miles south of
the Central Pacific Railroad, in the
Egan range of mountains, near the
town of Ely, the county seat.
The mines of this district were,
some of them, located as early as
1869, 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
we're worked for that kind of min
eral. A smelling furnace was erect
ed 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
this 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
similar 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. It
may be that the gold vein, or the vein
on the south side of the canyon is
separated, and forms spur, o, 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 to state that
the ore zone passes through the dis
trict in north-westerly and south
easterly direction and Robinson cam
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
the lead bullion carried large
amount of gold. Upon investigation
it was found that the
AULTMAN MINE
Was furnishing the greater portion of
this valuable metal. The ore of this
mine was of such character that it
could not be reduced rapidly, it being
decomposed quartz, large portion of
which was clay, which baff1ed the
most experienced shelters 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
a number of years. They construct
ed mill of ten stamps capacity and
reduced the ore by crushing and pass
ing the same over copper-silvered
plates. The process was incomplete
and the loss too great to make it prof
table. Under this lease they devel-
oped large quantities of ore that can
be made profitable by working on
large scale and with complete mill
