The Salt Lake herald. [volume] (Salt Lake City [Utah]) 1870-1909, 1896-10-02

For the past six weeks the officers
of the Northern Light Mining com
pany have been hard at work in the
arduous task of building a mill on its
magnificent Lion Hill property-that
is. on paper; and during this period
almost daily meetings have been held
in the companys Office in the Nc
Cornick block, and they have been
w-ited upon by nearly every archi-
tect and machinery dealer in this
country.
AT last, however, after making
careful eXancination of half a dozen
or more plans and specifications, and
after making a close inspection of
every cyanide mill in Utah, the COM
pany has fully decided upon the
manner of mill which it Will build,
for the same; the Silver Brothers, of
this city, being awarded the contract
for the machinery plant; While White
& Ford, also OF this city, secured the
contract for the construction and cree
ton of the mill building; and The
Herald is assured that when complet-
BED, which is to be within seventy-five
days from date, and at an estimated
cost of about $4,000, the Northern
Light mill VIII be the best construct
ed, the best equipped and the most
perfect mill to be found in this or any
ether country.
The plant is to have a capacity of
200 tons daily, and its machinery in
-s.T1 ..4s
horsepower COrlisS engine; two
seventy horse-power boilers: one Blake
ore crusheT: two sets of rolls, one of
which is q Wall, the other Cornish;
besides other mechanical inventions
and appliances necessary for the con-
Stl'uction OF q first-ciaSs cyanide mill
Six cast-iron tanks viii be put in at
first, with a total capacity Of fifty
tons of ore daily. The plans, how
ever, call for twenty-four tanks, and
the eighteen viii be added soon after
the mill is IN successful operation
The min building win be of capaci-
Gus proportions. and viii be built so
that the ore win be moved by gravity
from the mouth of the tunnel Of the
mine to the ore bins and then on TO
the failing dumps, with the exception
of a fifteen foot elevator, which viii
raise the pulp from the last sett of
rolls into the bins above.
The ore chute and bins, as shown in
the accompanying illustration, towers
above the main building and is so
constructed as to give ample storage
room for a large amount of ore, which
is fed through a chute into the Blake
crusher below; from Where it passes
on to the rolls and is then elevated
into the pulp bins. From the bins the
pulp is drawn off into cars and is
dumped into the tanks, when, after the
cyanide solution has dissolved all or
nearly all Of the gold in the ore and
has been drawn off into the precipita-
ton room. the residue is deposited by
gravity into cars below and thrown
out onto the failing dump.
The main building will be 24xS6
feet in dimensions; the tank room
z0x56 feet; the engine room 12x30 feet;
the boiler room 26x30 feet, while the
precipitation room will measure 16x24
feet, and the goodly size Of the entire
edifice can be appreciated and under
stood when it is stated that it will
take 5000 feet of corrugated iron roof
inT to cover it: and the best of it all
is that the plant viii be modern in it's
equipment, that it viii be constructed
on scientific principles and that in its
building all of the latest inventions
and appliances viii be utilized.
Many Of the readers of The Herald
are fs.nliHar with the history of the
Northern Light. which. in early days
was a noted producer of high-grade
silver ore. and from which several
fortunes have been made by a num-
Der of mining operators who are still
residents of Utah.
In the operation of this property the
high silver values were found near
the surface, and the mine was never
thoroughly prospected, especially as to
depth. When an exploration of the
however, it was discovered that the
rich silver zone was the Gaping of q
mammoth deposit of low-gTade ore
that carried values of from SO to SIS
in the precious metal to the ton, be-
sides a small amount of silver, and it
was on account of these lows grade gold
ores. and this only. that induced Mr.
Airs and his associates. Messrs. Wood
ruff. Crooks and Curtis, to take hold
of the property. as it was in this class
Of ore and its treatment by the
cvauide process that these gentlemen
saw an easy fortune within their
grasp.
Soon after the purchase Of the North
ern Light group, which embraces six
patented claims, six unpatented lodes
and three fractions, a company was
organized for its development and
operation. and it wae not long after
the formation of the company before
extensive development work was
under way in charge of Superintendent
Frank Hines, and this work was con-
fined to the prospecting of the large
