LOST CABIN MINE IS
REAL PRODUCER NOW
That six drops of pine oil should
have solved an 18-year-old gold min-!
ing problem sounds like a suggestion
from the Arabian Nights or even
more imaginative literature. Yet this,
in sober truth, is what has caused
the Lost Cabin mine to click after
long years of experimentation.
’ {Sunday afternoon, on invitation of ;
its owner, Attorney A. K. Wylie; we
drove out to the mine, which is situated on the slopes of Adin mountain a few rods south of the highway amidst the primeval pines of the
Modoc national forest. :
Here we were iet in for more than
one surprise. The Lost Cabin is not
a gold quartz. The ore is being taken out of an open cut on the mountainside. adjoining the mill on the
upper side. The finer fragments go
direct to the mill while the coarser
pieces are passed through a rock
erusher to reduce them to the proper .
size for milling. .
After the manganese steel balls of .
the mill have reduced the ore to
powder it passes down hill to the oil .
flotation plant. The principle of this}
is very simple. Three chemical re-.
agents are mixed with a liberal quan.
tity of water and air drawn through :
the mixture. The resulting emulsion .
looks like the suds of wash day when .
the soap is good and the water not
too hard. The gold adheres to tite
bubbles and so is separated from the
worthless material and deposited in
the form of concentrates. '
But you have read of the diplomats who will agree upon a proposition ‘“‘in principle’? and then argue
two years over the details. This
oil flotation process is somehting
like that. One of the reagents used .
to make the lather is pine oil. Of
this exactly six drops a minute—no
more, no less—must go into the
suds. If it should be five drops or
Seven the success of the process is
upset. To insure that this shall not
happen, part of the machinery is an
automatic device which day and
night drops~just the right amount.
The two other reagents are also
fed automatically, each at the rate
of 150 drops a minute, but since a
reasonable variation’ in the amount
does no harm, these are not so interesting. And what are they? No;
one at the mine knows. They are
trade secrets, closely guarded by thef
inventor. Wouldn’t chemical analysis reveal the secrets? Maybe! But
we happen to remember a manufacturer who engaged three chemists
to analyze a-mixture put’ out by a
rival. They all succeeded but no two
got the same results.
But we didn’t go down to the Lost
Cabin mine primarily for the purpose of learning how it was being
done but to find out what was being
done. With that enl in view we panned and saw panned a number of
samples of ore taken from the face
of the quarry almost at random.
Every one of these showed gold in
the pan; some of them in quite substantial amounts.
A piece of concentrate, perhaps as
large as ones two fingers yielded aj
long string of gold. Repeated ‘panhings of the tailings showed not a .
speck of color. In other words there
was gold in the ore, lots of gold in
the concentrates and none in the
tailings. It was a case of check and
double check which would seem to
demonstrate that here is a gold mine
plus a process that will extract the
ore. £ .
And how are the concentrates? j
We are not going to quote the figures
used by those who are supposed to
know about such things because
they seem fantastic. Mr. Wylie is not
worrying about the figures. He expects a substantial shipment of concentrates early. next month. Says he,
“let the smelter returns do the talking.’’ It is our prediction that they
wil! talk through a megaphone.
The genial attorney is fortunate
in having an experienced, successful. .
and businesslike mining man in
charge of the operation in the person of H. B. Lewis. Coupled with
his ability, Mr. Lewis possesses a
modest frankness that is engaging.
We asked him whether the flotation
process was purely mechanical or a
combination of the mechanical and:
the chemical.
He promptly answered “I don’t
know. That is something the experts
are arguing about.’’ He may not
know how it works but he knows
how to work it as was demonstrated
with the mili in operation Sunday
afternoon. _
There is literally a mountain of
ore in the five claims which constitute the Lost Cabin property. This
has been preven by a tunnel which
‘was dug and a shaft which was sunk
in years gone by, and a trench which
recen dug as well as by the

In a report submitted to the com‘pany, Mr. Haley states that the main
least haulage crosscut ha sexposed,;
pay gravel in the Central Hill channel for upward of 100 feet in width
and shown the depth of the deposit
to be htree times that originally figured. In consequence, the indicated
available tonnage, he asserts, is 200
per cent in. excess of the previous
estimate of 630,000 tons in that
channel alone, without considering
the probable tonnage in the Aetna
and other ancient water courses.
These will be developed as rapidly as
possible, the management states. ExAnother property viisted by the
association’s representatives was the

tract in the Ophir district. Mr. Anderson, the owner of the property,
has uncovered what appears to be an
excellent prospect. He has installed
