Nature Of Development Work, Etc.
All the work done so far is OF an eS-
ploring character. No attempt has been
made to locate rich ore chutes. and MIN
Ing has been done with a View solely to
outlining the presence OF the great veins
that penetrate this property, and to de-
terInne their persistsncy and continuity
Work done so far reveals tho presence
Of greater and wider bodies OF ore than
have been disclosed In any other prop
erty in the Bullfrog mining district In
so short n period OF development work
and. regardless OF the time occupied In
developing work so far. the presence of
larger ore body has been demonstrated
than In any other property of the entire
Bulfrog mining district, The Rush vein,
on the Rush Mining companys ground.
is shown TO be from 15i feet to 300 feet
wide, and tho Denver vein. on the Rush
feet wide exactly the same width
on the property of the Bullfrog Denver
Mines whe5S bo5S at depth % @
$50 per ton, is now being blocked out.
No such body of ore was indicated
in the great Montgomery shoshone
mine of Bullfrog at the same stage
Of development as is already demon
strated in the Bullfrog Rush.
Comparisons Of the present show
ing on the Bullfrog Rush with those
on other properties on Bonanza Noun
tain and elsewhere in Bullfrog at the
same stage Of development, puts the
Rush in q class by itself. Ten times
as good showing has been made
on the Rush as was made at the same
period on any other property, includ-
ing the Denver, Eclipse, Tramp, Hobo
and Gibraltar. It is believed by Con-
sulting Engineer Bailey and by the
rank and file Of mining men on the
ground, who have personally watched
the progress of development work on
all the properties on Bonanza Noun
tain, that the short period Of develop
ment warrants belief that the Bull
frog Rush Mining company owns the
greatest property on Bonanza Noun
tain.
They base this conclusion On facts. as
More of the Denver vein has been
opened upon the Index claim of the
Bullfrog Rush Mining company than has
been disclosed the property of the
Bufrog Denver Mines company Itself;
The average assay values In the tunnel
Bullfrog Rush Mining company ground
are even higher than they were on the
Denver vein in Bullfrog Denver Mines
company ground The character OF the
ore In this vein In both, properties Is
similar There is no reason known TO MI

Manner Of Mining, Ore Reserves, Etc.
It has already been noted that all
OF the work done on Bullfrog Rush MI
ming company ground has been prosecuted
with view to defining the veins and de-
terminlng the continuity OF the ore bodies.
and no attempt has been made TO block
out ore. At the same time, the work has
been accomplished In such n miner-llke
way that when the time arrives for the
blocking out OF the ore bodies with a
view to transporting the orc to mills In
the immediate vicinity, all Of the work
will have been found to be OF utility ard
none of 1t waste.
II Is now estimated by Prof. Bailey,
the consulting engineer In charge, that
sufiicient ore has already been opened up
