CD. HAS SOLVED
MILL PROBLEM

he Chris Young group of five claims,
with the bringing here of the richest
specimens of ore ever seen in Phoe-
nix and with a report from Harry S.
Bryan, general manager of the Min
erals Recovery company, OF Denver.
showing that in a low grade sample .
there was present a vanaolum con- ,
tent of 1858 per cent an equal con- /
tent of molibdate, gold and silver to
the value of $76.27 and aside from
all this about As per cent metallic ,
lead. the directors and stockholders
Of the United States Vanadium De-
velopment company yesterday felt .
that their dreams of the richest mine
in the southwest We're realized. 1t
was said yesterday that the problem
of a mill to handle the various ores
recoverable has been about solved
through the several tests recently
made and that another sixty days
is likely to see such a mill erected
and in operation on the property.
Fl. H. Temple, who returned yester
day from an extended stay at the
property, brought down samples that
run so far in excess Of anything yet
taken from the workings that even
these who had predicted all along
that only the surface had been scrap
ed, We're surprised.
According to Mr.. Temple, over 25.
000 tons of rich ore has already been
blocked out or is on the dump 1t is
believed that most conservative
estimate would place an average val
uation of $1,000 per ton on the ore
now in sight. and that large quanti-
ties of the ore will run several times
in excess of that valuation. This
estimate is based en- d recent quota
ton for ten per cent concentrates OF
81 per pound whereas concentrates
from non-seleCted samples show
valuations running from Is to IS per
cent and necessarily a proportionate
increase in valuation.
Speaking of the work now being
done at the property Mr.. Temple said
he found one shaft down "a feet and
at the 130-foot level, drifting in two
directions has been commenced this
working being in rich ore. This shaft
is in rich ore from the surface to the
bottom.
The lower tunnel has cross cut q
vein four feet wide of the highest
grade ore yet encountered on the
property
On the Young group, fun title to
which has just been acquired the
company is sinking 4 shaft on n vein
2eG feet wide. This shaft is being
sunk ut the hanging wall and the
entire bottom of the shaft is in rich
ore six feet wide.
The specimens which Mr. Temple
brought down were from the different
workings and these will be assayed
so that q better idea can be obtained
of the valuation of the richest ore as
compared with the average and low
grade ores
Our men are working like beav-
ers," said Mr.. Temple, "and each day
is bringing new surprises They
realize that they are working in the
richest deposits yet uncovered in the
southwest. Why, if we had no other
aim than to develop gold mine, we
have wonderful values, but the gold
and silver, even at a showing of SIG
per ton, is but secondary PROPOSE
ton as compared with the higher
valuations of the vanadium present.
and with positive knowledge now,
that we too lave practically as good
values IN molydenum, and a high
value in metallic lead. We are rush.
ing work and hone soon to have our
mill erected when we will be in posi-
ton to supply something of the de-
mand that is already being made up
/ on us for these products"
The report of Manager BRYAN OF
| the Minerals Recovery company. is
among the most important that have
recently been made dealing with the
values of the ores and demonstrating
! that it will pc possible to make prac-
tic2llv full recovery of all she valu-
able metals.

My Dear Sir
Yours of the 18th at hand. As
wrote yon a few days since. our
analysis of the ore sent us. has
shown conclusively that the deduction
TO 80 mesh, as was done on the last
test, would be far from an economical
treatment. We put the entire analysis
IN the hands OF a school of mines
man who will submit complete re-
port, which will be sent to you.
Naturally our first test was made
on the best of the sample sent us. as
Mr.. sullivan expressed his opinion
that as a, whole the sample was 'ot
low grade. AS shown by our first
test, the selected ore from the sam
pie went ten, tons times into one
crushing into fifteen mesh and you1
assay as reported to us, showed a
yanadium content eof 1858 per cent
The report to be submitted to vou
VIII show that in the concentration
of which the samples were sent to
you, our process gave an extraction
OF better than 80 per cent of tn.
Tree contents IN crystalized vanadate
moi1bdate and cerrussite. and LEAD
sulphides and that while our re-.
covery of vanadium content was moi
~ per cent, we do recover better thar
y per cent of all the free metal. As
explained in o former letter. the loss
or rather, that portion not recovered
is contained cbanoiaal,, ~, IL.
