Districts.
EDITOR YUMA SENTINEL

Our camp Is SI0auIly Improving
New and valuable discoveries of the
precious metals are of daily oc-
curence, and the camp is coming
out on its merits. We have had
no boom, we don't look for any,
there are no wildcat speculations
here, the discoveries made up to
date are genuine, and proper ex-
ploitation will prove that they
have merit. The Bonanza mill is
still pounding away on rich ore
from Bonanza mine alone, and is
furnishing it's monthly quota of
from $4,000 to $4,000 in fine gold
bullion. The Golden Eagle mine
of the Bonanza group is being rapi-
idly developed and very rich ore
encountered in all the drifts.
Rumor hath it that a 20 stamp mill
will soon be erected on this fine
property.
The Delhi mine is Bonanza No.
2, and is owned by Delhi& Roenne.
The developments consist of a tun
mel 80 feet in length at the breast
of which a shaft has been sunk to
a depth of go feet, disclosing a
three foot vein of fine carbonate
ore, the ore occurs at the face of
the drift and remains with it to the
breast-it assays 80 per cent lead,
35 ounces silver and II penny
weights in gold; this claim is 1900
feet south of the Bonanza mine.
The claim owned by F. D. Wells
and Jane Mcnamara of Phoenix,
adjoins the Bonanza on the south
and the Delhi mine its norther-
ly boundary. Work is progress
ing rapidly on this property and
very rich ore has been uncovered.
Located, as it is. between two of
the big mines of the camp and
Immediately adjoining both, it is
to be expected that large and
rich mine will be opened on this
location.
The Quinn mine is another
promising property. 1t is situated
about one-half mile northeast of
the Bonanza mine and adjoins the
Golden Eagle mine on its south
west end. The Golden Chariot
mine, owned by Peter Meyer & Co.,
located about one-half mile north
of the Golden Eagle mine, is one of
the most promising mines of the
camp. The ore is the same as that
in the Golden Eagle and Bonanza
mines; the development consists of
a cross-cut tunnel twenty-five feet
in length, which has to run forty
feet more to cut very rich vein
of gold rock.
A man named James from Lodi,
Cal, was here recently. He carried
a mineral rod, or as the boys here
call it a ''Hoodo Stick" I do not
believe that anything but muscle,
and tools, with plenty of powder
and fuse will reveal to US the ex-
istence of the precious metals in
Quantity. Nevertheless, it is a
significant fact that Mr.. James
rod would persist in dipping every
time he crossed the ore vein of the
Golden Chariot, above and across
the line of the tunnel for dis
lance of eight feet across the vein,
which has been uncovered on tor
of.the mountain. The tunnel will
cut the vein at a depth of about
one hundred and fifty feet. All of
the above mines are on the same
great mineral belt.
Forty miles northwest of here is
the Plomosa mining camp. Fol
over twenty years past placer min
ing has been carried on in this
vicinity with profitable results
In the summer of 1890, Harry
MacKinney and others while pros
pecting for lodes discovered the
now celebrated Yum Yum mine
which has recently turned into a
bonanza. This property is very
rich in gold, carrying a faint trace
Of silver. Working tests in the
arrastra have yielded $500 per ton
The vein is about 80 inches wide
at depth of 25 feet, and bids fair
to increase in width. That it is a
true fssure vein there is no doubt
as both walls are in plain sight,
The trend of the vein is northeast
and southwest; inclination about
80 degrees. This valuable prop
erty is owned by John Agard Of
Phoenix, Mack Wilson and others
of this place.
| A great many discoveries have
lately been made in the Plomosas
and an unusual amount of energy
has been displayed in developing
quite number of these prospects
into mines. This was to be ex-
pected where rich ores IN such
abundance moved the muscles
welding the pick and the shovel.
Plomosa is mining camp, situate
a short distance from what is
known as the Slate or River Range
The principal mines are on series
of foot hills or mountain spurs.
The country rock is slate, lime
stones, porphyries, granite and
various eruptiye rocks. The ores
occur in contact veins of segrega.

are opened along the line of con.
