Showing of Carbonate Ore Found in
Vein Thought Barren

WIN fHS19Hh eoNNNh
The situation at the Arizona Mich
igan property has improved greatly
in the past week and activities hav,
been proportionately influenced
when the southeast crosscut on TN,
300 foot level of the Telfalr shaft rar
through approximately 100 feet o
vein filling supposed to be the OLD
Dominion fault, without having beer
shown a color of copper the manage
ment decided To sink a Wine on tn,
foot wall of the fault and TO reveal
the contents of the vein at depth OF
100 feet or so below the level of the
crosscut. orders then came from the
management in Michigan to drift both
ways from the crosscut on the vein
Preparations were made for cutting
a station in the crosscut at the loca-
tion of the point where the Wine was
10 be sunk. This station was then
blasted out twelve feet I'm height and
covering floor area of sixty -four
square feet. After the first few
rounds were blasted out along the
strike of the vein small lunches of
carbonate copper ore were revealed
which grew more frequent as the dis
tance from the crosscut progressed
This condition is extremely hopeful
as IL shows that the vein FILLING car
ried some copper at least where as
before evidence pointed strongly 10

the Wine commenced and the drifts
off OF this station east and west on
the vein will be started in a few days
The crosscut southeast will be con-
tinued with the intention of cutting
another formation lying further south
that on the surface shows an equal
width with the old Dominion vein
formation. There is no reason that
this second vein should not be as
favorable as the first and there is
strong probability that it is in truth
not separate and distinct forma-
ton but simply one of a division of
the Old Dominion vein itself. All the
work at the Telfair shaft with the
exception of the station cutting is
being done under contract. The cross
cut southeast is at present 1916 feet
from the shaft
The Blackbird shaft is at a depth
of 44O feet from the collar and is not
at present being extended i'm depth.
The crosscut north from the 400 foot
mark is In the neighborhood of sixty
feet from the shaft and the south
crosscut from the same level is about
thirty feet in length.
The formation is a red and white
banded shale the bedding planes of
which are tapped or crossfaulted.
The formation is Of varying hard
ness and is cut up by small systems Of
faults that strike nearly east and
west and which are tapped or cross
faulted. The displacement in these
small issuras is invariably to the
north about six inches ana they then
continue downward unbrolen. on
the third level the same thing is evil
dent with the throw always to the
north. This would indicate that the
fault which displaced the vein a few
feet below the 800 foot level had
thrown it north and If il is assumed
that the two forces which caused the
big fissure TO be displaced and the
structure of the ground to assume its
northern Offset this is undoubtedly
true and the Old Dominion vein will
be found with a few more feet Of de-
velopment in the crosscut north on the
400 foot leNnl "A rlznnn SlIL-nr RnIt
