names of which were not learned, the
Great Republic and other companies
owning several properties each, all To-
Gated in one continuous line upon this
ledge.
The Buckeye and Surprise, adjoining
the Ivanhoe property, are much the
same character, the ore frequently run
ming very high in silver, and also carry
ing some gold. The developments are
limited, but more work will doubtless
be done on them at an early day.
The Alaskais the third property north
of the Ivanhoe, and is located but a
quarter of mile from Grafton. The
VEN filling consisting of GraitZ as in
the preceding properties, and in fact
along the entire vein, is considerably
leached near the surface, leaving a eel
lular low grade rock near the surface
which is expected to improve at the
depth Of water level, where this i'm
poverishiDg process has doubtless sus-
pended. The average width of the
Alaska vein is about ten feet. and dip
of about sixty degrees from the horizon
to the eastward.
The first development work done on
the Alaska consisted upon incline fol-
lowing on the vein, which was carried
down to depth of one hundred and
eighty feet. This mode of working,
proving unsatisfactory, a perpendicular
shaft was started, one hundred feet to
The eastward and sunk to the depth of
two hundred and nine feet, cutting the
vein at one hundred and three, and
again intersectlng 1t at two hundred
feet by a cro5scut. Water was then en-
couHtered in such quantity that il
could not be handled through the shaft
which was quite small. Since then a
new shaft has been commenced lower
down the hill, about three hundred
feet to the eastward. This shaft is
caculated to cut the VEN, at seven
hundred feet. AT two hundred feet it
will be one hundred and sixty feet east
of the vein, and about five hundred
feet from its Outcrop. 1t is calculated
by the manager, Judge Adams, in or
der to hasten the time of production
of the nIne to drive a crosScut at about
two hundred feet, and cut the vein,
thus cutting unlimited resources, which
can be drawn upon while the shaft is
being sunk to the intersection of the
vein.
In order to facilitate work and ac-
complish the object in view as eXpe-
ditiously as possible, fine new steam
hosting plant has been secured, CON
sisting of double cylinder, thirty
power engine. The new shaft at pres
ent is down about iifty-fve feet.
The properties located on the vein
north of the Alaska have thirty to sew
enty feet of development and show the
same characteristics, so far as theoreis
concerned. Occasionally a property
shows more massive quartz and the
less oxidation the higher grade are the
ores. The silver as a rule is found as a
sulphide.
The vein as 1T is followed northward
generally continues in the green por-
phyry, though in one or two instances
it was noticed running IN the contact
between the green and red porphyries,
the latter forming the hanging wall
About six miles north Of Grafton is
the Occidental mine, one of the last To-
cations in this direction made on the
Ivanhoe vein. The principal working
avenue to this mine is afshaft one hun
dred and eighty-five feet deep, with an
incline from the bottom down an ad-
ditional distance of thirty-iye feet.
The shaft cuts the vein at one hundred
and seventy feet, and from the bottom
of the incline the vein is again inter
sected by croscut. The vein has a
width of three to six feet, with a vary
ing streak of pay. AT present the
stopping consists of raise made on the
ore from the bottom of the incline to
the intersection of the vein by the |
shaft, a distance of about eight feet,
also about thirty feet in depth at the
outcrop of the vein, and for short dis
tance of the vein, and for only short
distance latterly. This amount of work
yielded something like one hundred
and twenty tons of ore. Six tons of
this amount were shipped to S0corro
and returned bet ween fourteen and fif-
teen dollars ton. One hundred and
ten tons were milled at a mill subse-
quently erected near the mine, the re-
turns of which could not b9 learned by
the reporter. The average vallle of the
ore is stated al twenty to thirty dollars
in silver and gold TO the ton. The mine |,
was worked oil a lease for some time,
but recently the lessees gave up work,
and now4it is expected the company, "a
st. Joseph, Missouri, corporation, will I
take hold of the enterprise again,
