Col. Wall Makes Expression
Full of Interest Saturday
to PrOSpectOrs.
GIVES HIS IMPRESSION
OF FAMOUS DISTRICT
Saving of Ely Values Is Not
Hard Problem to Be
Solved.

a visit to Ely that attracted unusual
interest both in this city ana in White
Pine county was the recent trip made
by Col E. A. Wall to this new and IA
nous treasure house. Knowing the
Colonel s ability as a mining man and
metallurgist, and the esteem in which
ne is held universally, one Of the burn
ing questions of the hour was his opin-
ION of the district, which be inspected
closely during his sojourn in and near
Ely. This question naturally followed
Col. Wall to this city, where there are
scores of investors interested IN Ely
and other White Pine properties. Col
Wall was requested, therefore, not only
by the newspapers, but by persons in
terested financially in that district, for
an expression regarding the Ely camp
and mines, and the Colonel has com.
piled with their requests. One of the
most significant portions of what the
Colonel has to say about Ely is that
which points out why Ely is not an
exclusive rich man g proposition. He
says;
Ely-MonZonite, considering its great
length and breadth and the uniformity
of distribution of the valuable metals
throughout the mass, is certainly most
remarkable. While exploration has not
yet proceeded sufficiently 70 afford any
thing like accurate information as TO
possible or probable limits, sufficient is
known to warrant the assumption that
workable ores exist throughout width,
IN places at least, Of nearly 1000 feet
and for a distance in length of more
than FIVE miles, besides giving reason
able assurance that work of develop
ment now in progress viii prove con-
tinuity of length TO exceed eight miles,
and a width, for considerable portion
of this distance, OF quit half q mile.
Thus far, | believe, the greatest
depth to which the valuable ores are
known TO extend is less than 500 feet,
probably less than 400 feet, but / am
informed that no indication of deprecia-
tion in values has appeared at the
greatest depth yet attained, and al
though in view of the nature of the
deposition. ii seems certain that at no
great depth values must fade out or
disappear altogether. There are pres.
ent strong evidences of continuity of
the ores without material diminution IN
the copper contents, 10 depths several
handred feet beneath any point here
tofore penetrated but whatever may be
the ultimate limit IN depth, length or
breadth OF this peculiar ore deposit,
no one OF the present generation need
worry over the possible limit Of tons
contained within its confines.
"Mr. Reqra, in his very able and
instructive address delivered at the
railroad, compares the copper deposits
of Ely with those which occur in the
monzonites of Bingham as identical in
character, and very generously accords
80 Bingham the credit OF having only
within the last two years demonstrated
the possibility Of profitable, practical
treatment of ores of this class. 1t is
L.4 -
which the copper deposit of Bingham
occurs is, in SO far as can be deter
mined from appearances, identical with
that of Ely, and the same is true as
60 the general form and character of
the mineral contents, but the presence
Of the copper mineral in this unusual
association at Bingham IS due TO quite
different causes TO those which pre-
vailed IN the deposition of the same
mineral ut Ely. In both instances the
rock had been previously, profoundly
crushed, breceiated, thus affording in
Vulnerable channels and minute assures
through which ascending or descending
Undertaking solutions freely circulated,
depositing their metal burdens In the
interstices of the broken mass, or re-
placing with minute grains Of copper
sulphide certain constituents of the
rock which had been first dissolved and
removed by the solvent power Of those
mineralizing waters.
Bingham VS.. Ely Deposits.
CAT Bingham the mineral was de-
posted in manner precisely similar
20 that which prevailed in the forma-
tion of tho veins of Butte, Mont, and
of other deep-seated veins throughout
the world, j. e., by ascending solu-
tions. The deposit being IN natural
form, an original sulphide, which was
later partially altered and changed, in
stu, by descending atmospheric waters
10 carbonates at and near the surface,
and TO chalcocite anil kindred second
ary products at greater Gepth, whereas
the deposits of Ely resulted from the
percolation of descending atmospheric
waters, containing in solution copper
derived from the decomposition of PIE.
