A PRACTICAL
ILLUSTRATION
What Braganza People
are DOingin Mining.
The Remarkable Showing in an Old
Property Covering Develop
ment and Production.

In the history of mines and mining
i'm Yavapai county of the past and of
the present, there is not more strik-
ing illustration of the benefits that ac-
crue from the judicious expenditure
of money and the wisdom given in
practical development, than that
which is following the methods of
the Braganza company III the opera
ton of the Henrietta mine on Big
Bug. Any one familiar with the
affairs of this property III its earlier
life of occasional spurts, when the
chlorider Quilted its veins, when It'll
CATION and personal matters were bit
ter. when every stamp was hung up, |
and when the usual decay necessarily
followed the neglect that prevailed,
will naturally feel somewhat disputa-
tious in looking at the present and
il contrast to that which has been
wiped out.
This property has undergone such
a complete regeneration in its meth
DDS of operation IN the past twenty
months. it may be cOnservatively
stated that today it is rated among
the reliable properties of this section,
and in addition to that it carries the
consideration of being one of the four
mining companies that monthly give
in dividends what others ordinarily
exact in assessments. While in its
earlier career it is true that the Hen
rietta gave to some of its operators
financial relief and to Others it over
burdened them with additional cares,
it is the knowledge, however, of the
men who today are behind 1T and
their methods of operating that gives
to this particular property, and Incl
dentalIy TO mining generally, re-
gard that shonld weigh favorably the
calling that is now and universally so
attracting the attention of capital.
The Henrietta OF old was generally
regarded by the miner as good
ground: the Henrietta of today
differs only in that sentiment by be
ing known is magnificent. Support
| ing this feature of its merited rating
there is this to say:
Development WORK.
From the beginning of work in
February of 1902, the old stunnel of
former operators extended about zoo
feet from the south end Of the hill in
on the vein. with occasional shafts
and drifts and other work. Today
this tunnel has been driven to the
north end of the mountain, dis
lance of 200 feet further, or making
in all tunnel 1900 feet in length.
This work was undertaken TO afford
not only the developing of the vein,
but it offers facilities to handle the
ore by tramways more readily and
economically than could otherwise be
given. 1t is at the end Of this tunnel
where the general development of the
mine is going on. or on the north side
of the mountain and 1900 feet dist: n
from where the old workings were To-
Gated. The old tunnel up to where
work was given by former owners has
not been further explored than what
prevailed when the property was turned
over to the present company. On the
extreme north end of the tunnel there
have been sunk by the Braganza peo-
ple two shafts, one at the mouth of
the tunnel and one at point still
further north 400 feet or TO within 100
feet of the line of the Gopher niue.
The main working shaft Is known as
No. l. and depth of 300 feet has
been reached. while shaft No. has
, reached depth of 400 feet. From
/ shaft No. I levels north and south
have been run for total distance Of
1900 feet. 500 feet each way, while
from the Gopher point Near shaft ,
connection has been made with drifts
10 shaft No. l. At the shaft at the
mouth of the tunnel the ore for mill
. ing aud shipping is raised, and from
this point the mill ore Is trammed to
T. the bins at the south end Of the tun-
7 mel 1900 feet distant, where a gravity
, tram takes it to the mill below for
reduction. The shipping ore that
reaches the surface at shaft No. l Is
