I Mines 81 Thar District. ilsl
A SENTINEL reporter learned from Col.
Joseph Tyson, Superintendent Of the On
ondaga mine, Stafford. District, who is at
present, in Eureka, that the. prospecta in
that camp are not less hopefulr than they
were. He did aot feel Ut liberty, owing 10
the situation he occupies, to give every
thing away, bat in response 70 questions
some interesting notes were pumped out
of him. TIE shipments made by the On
ondaga to Salt Lake have proved that the
mass of ore found from the surface down
will pay to mill. The returns are not al
lowed to be published, but they are satis-
factory, eminently so. The result is that
the company have made mp their minds to
put up reduction works on b Humboldt.
The nature of the works will be deter
mined by the nature. OF the ore as found
in further explorations. The prospect
shaft sunk on an incline OF about 30 de-
grees from the perpendicular is now down
1875 feet In ore all the way down from the
surface. At the bottom the ore has
changed somewhat from ita .gneous look

cur kidneys Of rich yellow carbonates,
also native silver, which was not to be
seen nearer the surface. The proposition
is to sink about 100 feet further INT then
complete the tunnel which was started to
strike the shaft at the proposed depth.
This tunnel is now in 200 feet and will have
to be run in 800 feet further. 1t is cal
culsted that it will cost Is cents per. ton to
dump the ore through this tunnel into the
canyon. Work Is being carried on by six
men on 10.hOur shifts-two men on shift
below and one man o. shift to run the
horse within. About five feet are being
made per day, and it is expected that in
about 20 days the shaft will be sunk to the
proposed depth. If the ore holds out to
the 235-level, and the appearance now is
that it will, the ore actually in sight and
that can be measured will, Of itself, be an
immense quantity. The size of the mill
that the company have in mind will be in
accordance with future developments, but
they have determined definitely to build q
mill on the Humboldt of greater or less
capacity, as every ton of ore extracted can
be worked to pay a profit. The ore taken
out in prospecting will pay all the ex-
penses of the company.
The Zanoli, Col. Tyson says, is still
looking fine. On the 50-foot level the
ledge has been stripped As feet northwest
and As feet southeast on a body OF high
grade yellow carbonate ore. The same work
has been done also on the 80-foot level, on
which the ledge, perfectly defined and
with smooth walls, varies in width from
one to seven feet. The mine has been
prospected to the depth of 112 feet, the
ore going all the way to the bottom in
quantity and quality as above, but water
has come in and stands so feet deep in the
incline. The six owners of the property
are working it by windlass and piling up
their ore on the dump without making any
shipments. They propose to run q tunnel
in to strike below the incline at q depth of
300 feet from the surface to drain the
mine. They expect, if the mine holds out
as anticipated, as in the case Of the Onon-
daga, to erect works Of their own on the
Humboldt. They have entire confidence
in their property. the ore from which they
had tested in Salt Lake, 26 tons going 81
ounces in silver (no gold) by pulp assay.
Nothing is doing 10 the numerous other
claims in Stafford, which are considered for
the present as mere prospects. Their
owners are waiting to see what is going to
turn up in the Onondaga and Zanoli.
