NEW IDEA On
ORES OF NEVADA.
lNeM Ynrk Mlninp Aee


Robert r. Hill. who has spent the
last Two months in Nevada. brings
with him some interesting accounts
regarding the scientific prospecting
and development he is doing out
there. Mr.. Hill is known for his habit
of solving a good many difficult ore
occurrence problems and for his pre-
sentation of a number of original
views regarding the geology of ore
deposits. He is convinced that
Nevada offers a particularly attrac-
tive field for a geoloeist or engineer
who is willing to study and apply the
results of modern research 10 the
peculiar occurrences of ore In that
state.
"PrOspecters who have been ae-
customed TO look for values In the
light of old precedents,' said Mr..
Hill this week, in discussing some
of the details of his trip, are apt
TO meet with good deal OF dissap-
pointment in looking over the newer
Nevada sections because of the alb
senee or unreliabilty OF the so-called
indications to which the old prospec-
tor is accustomed
Mr.. Hill has spent several months
at a new camp called Alunite.
twenty-five miles southeast of Las
Vegas and north Of Searehlight.

occurrences, especially those prin-
/ ciples which pertain 10 what thee
modern biologists term rock alter
alton and secondary enriehments.
The reason" said Mr.. Hill,
why as we so often hear. that ex-
perts and miners so often turned
down such places as Cripple Greek.
Goldfield and Cananea. was merely
because. when these places first
came under attention. the laws of
that particular ore occurrence, as
subsequently asertained by develop
ment and most arduOus geologic
study on the part of the United States
geological survey. were found 10 be
/ different from all known preeedents;
in other words. both miner and ex
pert had encountered new conditions
which had never before been inter
prefed or recorded.
The magnificent work in Nevada
of the geological survey at Tonopah
+ and Goldfield. has resulted in the dis
/ coYery and Interpretation of facts and

! individual capacity for research as
! NAV possess.
The topography, outcrops. altera-

/ Nevadaregion are apparently en-
i tirely different from all precedent,
! and the old precedent miner and en-
/ gineer as weel as the amateur inyes-
+ tor. are hopelessly lost In intelligent
! prospecting.
The ore deposits donot occur in
regular quartz veins in the old assure
/ vein type, but in what is known as
secondary quartz and other products
] of the alteration of the country rock
/ by ascending solutions which. accor-
ding to Ransome of the geological
survey, were acidic at Goldfield and
+ not alkaline. as usually Is the case.
THE result of this little differ
ence in the Undertaking solution
and it's chemical proclivities Is the
&
entirely different looking products
+ from those of which the old miner
/ is accustomed. One of these alter
alton products is a mineral substance
/ known as alunite. which character

We will find large bodies OF secondary

most of the great ore occurrences In
this portion Of the great American
desert.
we do not claim to have mine.
