The silver state. [volume] (Winnemucca, Nev.) 1909-1925, 1920-05-22

together with my own observations
az the obvious physical characters
tics of the formation, / have no hest
fancy in saying that the entire vein
matter. ranging in breadth from two
to nine feet. exposed on three sides
by the Stratford-Arthur shaft and
drifts therefrom should average at
least as high as the waste dump at
that shaft plus the value found by
distributing the returns from high
grade shipments made from the work
ings heretofore.
There appears to b about $500
tons on the waste dump which, ac-
cording to Thompson, assays ten dol
lars per ton. The blocked ore in the
mine. exposed on three sides. will
figure co%nservatively $500 tons. About
400 tons have been shipped. the latter
appearing to have returned in round
figures 100000. Applying the waste
dump average as sweetened by the
$50, 900 referred to, the ore exposed
~aggregating $500 tons, including the
dump, may be properly estimated as
having had not less than a $15.75
value per ton in place. The average
of samples along the lowest level
gives a value of fifteen dollars for ore
in place above that level and for an
average width of five feet.
This property is richly entitled to
development. / would like to see the
shaft sunk another $50 or 200 feet
and drifts run north and south in
that segment of the vein at ffty-foot
lifts. A crosscut, to both walls OF
the ore zone should be run, prefer
ably on the 150-foot level.
"Trenching, to be followed by one
or more shafts on favorable outcrops,
should be carried out or the vein
segments o ~prospected by the STRAIT
ford-Arthur shaft system.
Il consider this a remarkably
promising prospect which is worthy
of development on a considerable
scale. / may go further and say that
il is the best showing | have seen in
any new territory in Nevada for many
years. f"
Arthur Perry Thompson in his re-
port on the Broken Hills property just
made public. says:
The property of the Broken Hills
Silver Corporation lies in a region
of profound volcanic disturbances. A
strong vein cut into segments 500 to
1900 feet long by three strong north
east faults and known 10 contain
valuable silver ore shoots where de-
velopment has been done at its north
ern extremity, runs through the prop
erty for 2100 feet. The vein Is found
in a narrow belt of siliceous ande-
site. Parallel to the vein runs a
zone of intense faulting and crushing.
The influence of this large zone of
faulting on the formation of addi-
tional silver ore bodies in the prop
erty is obscured by a Gaping of ba-
salitc flows and tufa which overlies
the ~ore-bearing s~iliceous andesite of
the fault zone.
"The evidence Of the strong silver
vein now exposed up to a depth of
$50 feet, from which approximately
100000 has been produced in high
grade silver ore, and in which $101,-
375 in additional ore reserves have
been developed. is ample to warrant
a complete development at depth of
that portion of the vein with the ex-
pectation of finding a continuation of
this heavy naturalization as greater
depth is gained on the vein and of
finding additional rich ore shoots as
the unexplored portions OF this north
ern area of the vein Is opened up.
Outcrops of the same vein on the
Broken Hills Claim, to the south, are
also worthy of complete Investigation.
The Broken Hills vein beneath the
Gaping Of tufa, to the west, also
mark the property as one of unusual
merit"
