ITO the north"
How far is the throw ?"
80 A hOlIt 1G faotD

To the north"
How far is the throw?"
| About 16 feet ....
How near to the clay seam does the
ore come on each side?'
TT comes against it on the west side
OF the fault, but there is a foot Of
| crushed material between the ore and
| the seam on the east side"
is that foot of crushed material
ore?"
II can't say whether or not it is
dragged ORE
Have you other places where you
have veins cut in two outside the
| faults?"
There is similar breaking up of the
south ore body on the 500 level.
| And what is the extent OF the dis
| placement?"
Approximately % feet in one instance
and so feet in another
LAS to these pieces inside the uts,
the throw was south, them!
Yes"
THAT is to say that the west ground
| moved south?'
'Or the east ground moved north?'
Mr. Hughes pointed out another place
on the 500 level between the faults, and
the witness said there is another 90
foot displacement there; and still an
other at a different place, OF SIX or eight
feet. The throw at the last place Is
hardly noticeable.
The witness said that, while the east
| section of the faulted ground remained
stationary, the ground between the
faults moved two-thirdGs of the distance
of displacement and then stopped, ana
the country west of the faults moved
the final third of the distance farther
The first and greater distance was
made on the plane of the east fault,
and the last and lesser distance was
made on the west fault plane.
In the opinion of the witness TWO
fractures occurred simultaneously, ana
the movement of the middle and west
erly segments of ground were contemp-
oraneous, the west segment moving the
faster the middle segment being rolled
and tumbled and crushed between:
Upon this theory the crushing and
grinding on the west of the fault plane
was less than that upon the east fault
| plane.
How far west do you have to 60
Mr.. Tyler from the east fault till you
| find unbroken granite" asked Mr..
| Hughes.
From one foot to 12,' said the wit
ness.
what is the greatest distance?'
| "On an upper level there is an area
of so feet"
| DO you mean that that whole 50 feet
| is ground up like the one-foot places
you just mentioned?'
mo; it is not so fine
Did the porphyry cause or aid in the
causation of the east and west fis-
| sures?"
Il think the porphyry preceded the
| veins, and I do not see that 1t did,
| The witness was asked fthe east ana
west veins do not converge where the
| faults cross them, and he measured the
! distances between them close to the
| faults on either side and at the eastern
and western eXtremities of the east
ern and western systems respectively.
The witness said that the western veins
approached one another near the faults.
| but the eastern veins maintain an
equi-distant relation.
Mr.. Tyler, are you of the opinion
| that the naturalization of veins
is richer at functions and crossings
than elsewhere?" asked Mr.. Hughes.
| Not always said the witness.
| The ore bodies between the faults
| came under examination. and also the
slopes upon them next to the faults.
The witness said the assures running
through the slopes are difficult to
| trace.
Then you do not know what the dip
| and strike of the f1ssures were before
