and volcanic mud, the enrichment no
doubt coming from the solutions
percolating through the vein. In
some cases the vugs or fractures
carry no values, but usually carry
a good grade OF ore.
within the walls of the vein the
ertire mass contains values with
lenses of very high-grade ore ly-
ing irregularly and usually contain
ing a large proportion of jasper. The
three principal slopes in the mine,
namely the Bonanza, east Bonanza
and Davis Slopes, are no doubt the
faulted segments of the same ore
chimney and have been displaced by
step faulting; in all of these slopes
there is ore of good milling grade
still left on the hanging wall and
in many places the low-grade ore
has been left on both walls.
The three above-named Slopes
are now connected, and while they
we're all four at different times
and considered seperate ~ore-chutes.
it was not until the mill grade OF
ore was worked over an extensive
area that they we're found to con-
meet up by small chutes of ore lead
ine from one stope to the other
In carrying out the proposed plan
of working out all the ore now left
en- the walls of the slopes and apply
ing the shrinkage system of mining,
conditions similar to the above may
be encountered and be the means
of leading into orebodies as large
if not larger than those that have
been taken out.
All of the lessees now operating
O.. the property are doing so with
the intention Of developing shipping
ore of a $40 grade or better, and
in carrying on their work will no
doubt extend the zone Of milling
grade ore to a considerable extent.
The lessees are good, practical min
ers. and are familiar with all of the
different camps in the state, and
the fact that they have selected this
property to devote time and money
10 develop should be very gratifying
to you as we'll as to the stockhold-
ers of your company.
With all the lessees now working,
other applications on file in the
office for ground, and the parent
company actively engaged in de-
yelopment work, your property VIII
in the next year be more thorough
" prospected than it has been at
any time in the history of the dis
trict.
Production: The past production
~ the property has been over $aoO,-
OGO, most of which has been pro-
duced by lessees in the early de-
velopment of the mine.
From what is now known as the
Bonanza stope, ore was produced
over a working width Of 20 feet
that averaged over 500 per ton in
gold value, and a carload OF ore
shipped from this stope to the
American Smelling & Refining COM
pany in 1909 yielded the lessees
S~7,924.93 net, the parent company
receiving $2.324.27 in royalty, the
average gross value of the ore be
ing $191.97 per ton.
During the period between Jan.
list, 1909 and Oct. 18th, 1919,
S44O. 900 was produced, all OF the
ore shipped averaging $43.71 per
ton.
The lessees operated under a slid
ing scale of royalty. the parent
company receiving on the above pro-
duction 10 per cent on all ore as
saving less than $50 per ton n y
per CEN on all ore assaying over
800 per ton. Owing to the more
favorable conditions under which a
lessee can now operate, the follow
ing scale has been adopted: Ore
assaying $50 or less, 10 per cent,
$50 to SIS, 20 per cent; $40 to
$500, 25 per cent; on all over $l0o,
80 per cent.
Mine Recommendations: In mati-
ing the following recommendations
] do so by reason of a long prac'
teal experience in handling differ
ent properties, some of which were
very similar in character to the CON
ditions now prevailing in your
property.
While it is impossible to estimate
tie tonnage left in the old Slopes
that can be mined and milled at a
good profit, it is safe to say that a
tonnage equal to that mined up 70
date can be taken out above the zoo
level, to say nothing of the great
possibilities below that point. IT
has been my experience that the ac-
t,,al stopping of ore. where the vein
IS so wide, proves to be the very
best development work that can be
nut into effect. The past opera
ticns demonstrate beyond any ques-
ton the fact that of h~igh-grade
lenses being in the vein, all of which
produced a large tonnage OF ship
