REVIVAL OF THE MINING
INDUSTRY OF NEW MEXICO

works.
Immense Production Of Copper.
During the first two months. NOvem-
Der and December. 1911, while only one
section of the mill was running. 9S6,Sf0
pounds of copper was produced On
the same basis since the four sections
are completed 1000 tons of ore should
be concentrated daily and 1852, 100
pounds of copper be produced per
month. When the fifth section OF the
mill is completed the monthly produc-
ton should be 2,465.79O pounds of cop
per per month, or a grand total per

The MoEOIIon District.
The Deadwood mill at NogOllon, N
NJ, presents enough unusual features 20
warrant its description, 1nasmuch as u
is one of the first uptOdate milling ana
cyaniding plants of latest kind intro
duced in New Mexico and which IS rev.
olutionizing the treatment Of goid an, ana
silver ores and the same styled mill
with tube mill added is being intro
duced in Twin Peaks, Apache Box DIS
trict 1t was designed by John W.
Kniffin. cyanide metallurgist and all
the mill equipment was furnished by
the Ell Paso Foundry and Machine com
pany. The cost of the mill was $4,000.
OF this cost 20 per cent was for labor
and grading and Is percent for haul
The mill was designed to treat the
gold and silver sulphide ore of the
mine. The chief gangue mineral is
of the ore treated has been S12 per ton,
equally divided in gold and silver. An
extraction of Sc per cent of the gold md
IS per cent of the silver is obtained
De In Vergne Oil Engine.
The power plant consists of a 125
horsepower de la Vergne engine OF
the internal combustion type, which
nj a maximum consumes $50 gallons Of
crude oil every "a hours. The cost OF
the crude oil delivered at the mill IS
IL cents per gallon. The cost of wood
is prohibitive and the saving by the
new oil engine is great.
The entire plant is nearly continuous
and automatic. The average treat
tons of ore being treated daily
Ernestine Mining Company.
The Ernestine Mining company
and the SocOrrO Mine company, also
at Mogollon, have installed oil engines
of this type Wood fuel required to
costs about $3.50 per day, whereas oil
fuel will accomplish the same results
for SIT per day. The Socorro mine re-
ports a saving with the oil engine OF
The MogoIIon district is growing to
be one of the richest and most pro-
ductive gold and silver mining dis
tricts in the United states, In 1910 its
Weld was about S1,O0O.OO0 and it is
claimed that in-19l1 the production
was about $4,000, 900.
Many Good Companies.
The leading mining companies oper-
ating there. are the SOcorro Mines COM
,pany, owning the Little ranny group
and cyanide mill of 125 tons capacity
per day. The annual production is
said TO be over 100000 and 5000 tons
of ore is mined per month.
The Ernestine Mining company, own
ers of the Last Chance and Top mines
and a 100 ton cyaniding mill and pro-
duces about 22.640 ounces of bullion
and 16 IL tons of concentrates per
month. It is now paying a regular
dividend of one percent on its capitali-
Zatfon. 1t was the first company to in
stall a successful cyanide plant in the
United States.
Ernest Craig, the president. has been
elected member of the British parlia-
nent, and the company is largely Brit
ish stockholders.
