made some study of the Gold Hiii

>ment to The international: :,
"While I am not familiar with
the exact location of the strike
on the pyle property, I can say
that I have devoted some time
10 a study of the district in gen,
eral. / found that it is traverseo
hv q number of true fIssure veins,
y yerv Y generally mineralized. and
which apparently continue to
much depth. The general forma-
tion and the vein character is very
similar to that of some OF the
most productive mining areas IT
Colorado. Development to date
seems to have been confined to the
oxidized zone, and when the norm
al and expected lean zone between
the oxides and the sulphides was
encountered, all operators appear
to have quit. believe opera
tions in these fissure veins should
BE carried down well below the
water level, and if mis- is done,
Won may have a most important
gold-silver-lead production right
here in the outskirts Of Nogales.

Howard E. Davis, Mining ge-
aIogist well known all along the
Pacific Coast from southern Cali
fornia on up into Yukon Terri
tory has spent considerable time
during the last few months study
ing and sampling "Gold HIP ex-
posures. He has been doing this
work quietly, and knowledge OF it
came to The international through
accident. Thursday night, at the

Of the Mount Benedict (Gold
HilD country. and have cut many
samples. Ny sampling has been
very 'hard-boiled.' have tried
to reject stuff which looked too
good for fear of sailing myself.
Yet can say that the average re-
suits of a large number of SAM
pies indicate that large tonnage
of milling ore can be developed
around Mt. Benedict, and that in
developing ore of milling tenor it
i likely that occasional lenses of
spectacular value will BE found.
"In the past, from shallow
workings, gold ore specimens
worth many thousands of dollars
per ton have been found, and re-
cords show that ore running bet
ster than 500 per ton has been
shipped on a tonnage basis. This
last ore was gold-lead ore, rich in
lead,. but settled for only on
gold basis because lead at that
time had no real market value.
"Not all veins in this zone are
inportant. even though they are
mineralized. Yet there is a series of
deep-seated, true fissure veins,
filled with dispositions of mineral

and crustification), we'll worth
deep and extensive exploration.
"Oxidation in this zone extends
to considerable depth. but the
water level Of the Santa Cruz
river should nearly mark the
downward limits of excessive
oxidation. At some little distan-
Hce below this water level should
be found the zooe of enrichment

held in the upper reaches Of the

grated downward ahead of erosion
"The workings I have seen stop

real digging should have started

inches to eight feet in width, con
tanning from $500 TO $4,000 per

cold-blooded samples. Picked
specimens from these zones have
run to several hundred dollars pc, |

PERSONALLY, I. believe that RICH
here in the "front yard of No
gales you have just. as much reas
on for gold rush as can be
found in any of these resurrected
districts which are now filling the
papers, with reports of gold dis
