per-MlnIng Notes of
Interest

The old TipTop mines, situated sixty
miles south of Prescott, are to give up
their treasures again. The mines were
once noted for their great richness in
silver, and new life, after an idleness
Of many years, is to be injected into
them again. The early settlers Of Mari
copa and Zavapai counties remember
the days at Tip-Top. The camp was
riotous and turbulent one, and money
and liquor were plentiful.
The Gold Road mine in Arizona, on
the 500 level, has one of the greatest
bodies of ore ever opened up in the
territory, says the Mohave Miner
From the shaft $50 feet west the ore is
unbroken and ranges to nearly twenty
five feet in width. In the breast the
main ore body is eight feet wide, and
samples taken across the entire width
gave results Of 1921 gold to the ton.
This width Of ore Is broken in driving
the drift and crosscuts show the ledge
to have enormous proportions. On the
level above great ore is also being
broken down. Eighteen machines are
in use in the property and the big mill
will be kept busy II more machines have
to be put in. The results now obtained
at the mill are nearly perfect, the ore
remaining neutral and ideal for ANAL
gamation and cyaniding.
Los Angeles Capital
a. ~
elements the Grand Central Taiings
pile, situated at Fairbank, Ariz.,
thought for many years to be impos-
sible of treatment by the cyanide
process, Is now being worked success
fully by the shines Tailings company
Of Arizona.
The company was organized In this
city principally through the efforts Of
Childs & Koebig, the metallurgists and
chemists, and it was largely due to
their untiring efforts and experiments
upon these tailings that a complete
plant with a capacity for handling 200
tons of sand per day was constructed
and Is now in successful operation.
The dump consists Of 10000 tons Of
mill tailings that average $3.50 per tor,
out of which they extract So per cent
of the gold and IA per cent of the silver
values; the relative values of the two
metals are as four to one In favor Of
the gold. The sand receives a contact
with the cyanide solution Of ten days.
A solution of one-half of 1 per cent
is used. but the consumption of cyanide
is only one and three quarter pounds
per ton. The cost of working these
sands is "a cents per ton, thereby leav-
ing a handsome profit.
The officers Of the company are ]. z.
Harmon, we'll known attorney OF this
city, president; 8. v. Childs, vice presl-
dent and general manager; w. K.
Maull of Phoenix, Ariz., secretary. The
directors are j. e. Harmon, s. V. Childs,
DR.. julius Koebig Of Los Angeles and
w. X. Maull and Andrew Trumbo of
Arizona. The company is capitalized
for $4,000. The stock Of the company
is nearly all held by its directors, and
now is said to be easily worth four
times its par value
Exports Of Copper
Exports of copper from the United
States during August, as reported by
the New York Metal exchange from

tons. This is 2942 tons more than the
exports for the preceding month. The
figures for the eight months ended
