SOME MIN ING NOTES.

a Trip to the Geddes L. bertrand
n Some Other Mines-A square
Meal and Pete Hansen on q Dogs
Tail.
Yesterday morning a SENTINEL reporter
went, at the invitation of Mr.. G. L. Broy,
with him, Colonel E. N. Robinson and Mr..
Pete Hansen, to visit the Geddes & Ber-
trand mine, Cabin Home mine, the Secret
Canyon Tunnel, and the Monumental Tun-
nel-all Of which are located in Prospect
Mountain.
THE GEDDEs AND BERTRAND WORKS.
The party first visited the hoising works
OF the Geddes & Bertrand Mining Com
pany, and were kindly shown through the
works by the gentleman in charge Of the
various departments. On this subject the
SENTINEL has already published one long,
descriptive article. 1t is not our inten-
ton to describe it again with any particu-
larity until the works are set in operation,
which will be some time in June, when the
subject will in many respects become new.
1t would do anybody good who is afflicted
with the blues on account of the tenn
porary unflattering outlook in some parts
OF Eureka District to go out to Secret
Canyon and take a sight at this mammoth
lnstltutlon-to see what faith others have
IN the district. When a ompany goes to
work IN cold blood and invests, at least
o2oO,OOO in reduction works, they certainly
have a good stock of faith in the enter
prise they undertake. When these works
are started up it will be a spectacle worth
the while of every person here who needs
to borrow faith to take a trip out there and
look on. The building covers the largest
space occupied by any similar structure
on the Pacific Coast, measuring one way
23O feet and the other ITO.
II REASON FOR THEIR FAITH.
These works have at present a capacity
to reduce fifty tons of ore per day, which
can be readily increased to eighty. There
are two serious questions asked by the
skeptics. These questions are, first, is
the prospect of ore in the mine sufficient
to warrant the investment of such large
sums of money? And second, presuming
that there be plenty Of pay ore, can it be
successfully reduced? The latter is the
more important question, as the belief is
general that the Geddes & Bertrand con-
tains in sight, to say nothing of what may
be developed, a vast quantity of ore that
will pay a profit for milling. In answer
ing this question we can only say that Mr..
Z: L.. Strong, who is superintendent, and
who has had large experience in dealing
with refractory ores-ore, in fact, of this
very sort, says he has successfully reduced
it. He has no doubt that the reduction of
the antimonial silver ore of the Geddes &
Bertrand mine will be perfectly accom-
plished and without any difficulty. He
gave our party yesterday a short lecture
on the subject and demonstrated by a
practical test that the thing can be readily
done. He presented two glasses for us to
look at. One of them contained pure
water, which held in solution gold, silver,
anthony, lead, copper and zinc. The lat
ter fluid was perfectly transparent and
could not be distinguished by the eye
from the pure water. He poured some
flux, the preparation of which is his secret,
into the water, and it had no effect but to
discolor it. He did the same with the
other liquid, which he stirred for a mo-
ment, and then held up to the sun. I'M
mediately the metals began to be precipi-
tated, and in a minute had all settled at
the bottom of the glass. The same treat
ment will be used in the reduction works,

THE MINE.
In order to answer the first question |
%propounded by those who have less faith
in the Geddes & Bertrand thar those who
have put their money in it, it will be nee
essary to talk about the mine. We are
enabled to speak intelligibly about it
through the courtesy Of Mr.. A. W. Atchi-
son, foreman, who kindly escorted US all

force OF three mon we're put to work to
clean, and Monday they began to take out
ore, raising 100 tons per day. The ore is
being taken from the 75-foot level. On
this level there Is a large ore body, the
dimensions OF which are not known eg-
ceps that 1t eXtends to the surface. 1t
holds out as far IS prospeoted in all direc-
tons. Tho ore body on the 160-foot level
is also very large and yields as far as
developed. II extends to the surface and
down to the a20-ioot level. There is no
prospecting going on on the 320-foot level,
the same being flooded with water. 1t ia
impossible to form anything like an acous
rate or even approximate estimate Of the
quantity of ore in sight, to say nothing OF
that which it is reasonably expected will
BIO uncovered. Some very large estimates
have been ventured, but it ia safe to oalcu-

to u the works for twelve months. The
ore is Of various grades, running from 1915
to 5000 per ton, and 1t is probably an en-
tirely safe estimate that all through the
mine it will average $40 per ton.
THE CABIN HOME.
This is a prospect Of n OF the many
lodges that traverse Prospect Mountain
north and south. 1t has been worked by
, =, .,o1;na of az lapraao 10 a 1anfh ~ IN
feet. In working the ledge the true assure
vein has been followed from the groupings
down, terminating in a breast of fair-look-
ing ore, some samples of which assayed
from SIS to S125. This property is just
below and adjoining the Irish ambassador,
and is owned by @. l.. Broy and E. N.
Robinson. Work will be shortly resumed
on this claim.
THE SECRET ANY TuNNEL.
The tunnel on this property has been
pushed 1870 feet in hard, blue limestone, a
formation difficult to penetrate, but favor
able for finding ore. Four men are at
.work-night and day shift. This mine is
an incorporated company, and Is princi-
pally owned by E. N. Robinson, Peter
Hansen and Captain Foley.
THE MONUMENTAL TUNNEL.
This claim, which has already been de-
scribed in the SENTINEL, has prospected on
the tunnel line 140 feet. Several seams
have been cut which are presumably feed
ers from cross lodges above. The face OF
the tunnel is at present liz quartz and spar
intermined with galena. The main ledge,
which stands out in bold groupings and
which the tunnel Is being pushed to tap,
will be reached within the next fifteen or
twenty feet. Four men are employed on q
contract to run 200 feet.
A SQUARE E
If there Is anybody in Eureka who has
an idea that the Secret C%anyonites don't
know how to live he is greatly mistaken.
