The Anaconda standard. [volume] (Anaconda, Mont.) 1889-1970, 1899-10-03

vein that does not come to the sur
face and cut it off at the west fault.
He was asked where ore might be
found opposite the end of the south
vein inside the west fault, and he de-
scribed the inter-fault slopes on diff
ferent levels, next to the west fault
He said that the two ore bodies be-
tween the faults are the fiat ore body
and the rear ore body. The ore body
opposite the south vein, inside the west
fault, is the fiat ore body, and the ore
deposit opposite the north connecting
vein is the rear ore body.
I'm what manner does the fiat ore
body oppose the south vein at the west
fault?" asked Mr.. Patterson.
1T is cut off from it, and its dip is
l1uch f1atter," said the witness
The witness stated the number Of lev
els upon which there is ore inside the
faults.
State whether or not these veins
west of the faults are well defined and
easily followed" said Mr.. Patterson.
Arc Well Defined.
They are. They have not been
mined in irregular chambers, but in
regular course along their strike and
Dip said the witness.
The witness said that the veins east
of the east fault are the Snohomish,
north, south, Windlass and Berkeley.
which does not include the intermediate
streaks. There is another vein still in
the Batterman raise called the enargite
VEIN Mr. Tyler described these veins,
and said that they all end at the east
fault. at the west. He also told where
there Is ore opposite the west ends of
the veins inside the faults. He said
that in one instance there is crooked
fragment of ore inside the fault wall
opposite the north vein.
'SWhat is the proper apex of a vein?'
Do nm
1.-THE line connecting the highest
points on vein is the apex, surely
said the witness.
Where do the veins east of the east
fault apex?"
"Under the east wall of the east
fault, at their westerly ends and on the
surface for the rest Of their lengths
Gust draw your pointer along the
apex Of the Windlass vein on the model,
under and on the surface both.
The witness drew line up the east
wall of the east fault from the lowest
level ito the surface and then across
the surface.
Are there any workings at the east
ends of any Of the veins west of the
faults that follow the veins to the sur
facet" asked Mr.. Patterson.
NO. said the witness.
Windlass Vein.
The witness said that the u raise
goes up through the Windlass vein,
through the faulted area and the
ground above the latter, cutting the
ground east of the fault, the faulted
ground ending in the ground west OF
the fault The Windlass vein in the
raise stops at the east fault, but there
is a small streak in the raise where 1t
passes through the faulted ground and
a vein in it in the ground on the west
side and above the inter-fault area,
The witness said that there IS no con
neetion between the Windlass vein IN
the raise and the inter-fault streak and
west ground vein above.
The witness said that raise 451 is on
the same vein that raise " is on be-
tween the faults. Raise 451 is entire
ly between the faults.
"State how you know these raises are
on the same streak between the faults.
said Mr.. Patterson.
because the vein is visible in the
workings said the witness.
state whether the Windlass vein
apexes through the Y raise
mo, sir; it does not"
The ''77 AZ raise was taken up. The
witness said that this raise runs up
from the 450 level, from the workings
on the north vein east of the faults.
Where does this raise leave the
north vein-at what level?" asked Mr..
Patterson. ..
''At the 21o Michael Dewitt, which is
a. little more than 210 feet below the
surface"
Does Not Appear.
ut does not"
Docs the north vein apex through
this raiser"
mo, sir; it does mott
The witness stated that in large
part of the raise above where 1t leaves
the north vein it is destitute of a vein
altogether.
State the condition of the ground
between the faults" said Mr.. patter-
THE ground is much broken up. The
portions that appear to be the more
solid are in large blocks that have
charged their relative positions" said
the witness.
The witness said that there are sub
ordinate cracks between the faults and
that they rarely have the same pitch
or dip as the main assures. On the 400
level there Is much evidence of the
intermediate faulting of the rock car
rying the fiat ore body. On the 30
level there is a long cross-cut inside
the faulted area, and it shows many
fragments of veins, some of which can
be traced on their strike and some OF
which cannot.
Mr.. Tyler said that the clay selvages
on the fault walls vary in width from
an inch or two to 10 or ~ inches. Some
times the broken and brecciated ma
teral next to the clay selvage, inside
the fault crevice, has very narrow
width and the solder masses of the
lnter-fault country come up closer to
this clay.
Some specimens of the clay seIvage

evidence. One sample of hardened ma

witness stated that the samples were
from many places and showed that
the same materials could be found in
different localities and We're not local
formations.
