Though the original condition of the ore was doubtless sulphide, it now
contains, as the result of oxidation, hematite, limonite, magnetite,
malachite, azurite, chrysocolla, cerussite, wulfenite, chloride of
silver, manganese oxide, and metallic gold. The value of the ore lies
principally in the gold contained, though in one portion of the ore
body, near its eastern end, rich chloride of silver ore is found, with
but little gold. The physical appearance of the ore is no criterion of
its gold contents, as two pieces, with identically the same
characteristics, will differ widely in value. One may contain $2 or $3
in gold, the other several hundred. Should ever a mill be erected in the
district, this ore can be worked to a profit, though this single ore
body will alone scarcely justify the construction of a mill.
On the south side of this fissure or slip is a vein which runs nearly
parallel with the chambered vein above described. This vein can be
traced for several thousand feet. In character the ore is similar to
that found in the Imperial lode. Assays running over $200 in gold have
been obtained from this ore, and $50 assays are not uncommon. The vein
is quite small, ranging from a mere seam to 2 feet. Scarcely any
development has been done on this vein, though it promises better
results than the large “vein chamber.”
The developments on the Gladstone consist of a shaft 60 feet deep. The
first level is cut at a depth of 30 feet from the surface, where drifts
have been run for a distance of 30 feet each way from the shaft, on the
course of the vein, and a crosscut, 28 feet north. East of this, a
15-foot shaft has been sunk in a good sized cut. A large open cut, 100
feet long, has exposed the upper portion of the ore deposit perfectly.
Other superficial work has been done at various points along the vein. A
tramway of 1,700 feet has been constructed from the mine to the bottom
of an adjacent cañon.
OTHER CLAIMS.
In the vicinity of the mines described in this district are numerous
other claims, some of them having considerable development, but all
lying idle at the time of my visit. One claim has an 80-foot tunnel, and
shows some lead and silver ore of good grade. This claim is patented.
THE ALVORD MINES.
Twenty-three miles northeast from Daggett are the Alvord Mines. The
property has changed hands several times, but is now owned by a party of
Pasadena capitalists, who have under consideration the reconstruction of
their mill, which was burned in September, 1891.
The property consists of six full claims located on one mineral-bearing
zone. The strike of the belt is a few degrees south of west. The mine is
well equipped. The company also owns a millsite at Camp Cady, on the
Mojave River, 9 miles distant from the mines, and valuable water rights
at Paradise Springs, 11 miles northwest from the mines, and a spring
about 1½ miles east of the camp, which is used for camp purposes only.
