the witness said:
THE upper parts Of the loae will

copper is reprecipitated by sulphur

the copper sulphide as found i'll the
lower levels. There was better
chance for deposition between the
faults because the material between the
faults was more crushed. below this

approached by some OF The mines

to iron again. 1t is said that the cop

into iron This is true. but | believe
the mines will pass again through this
iron and reach copper that is still rich

sulphate and goes down to be precipi-
tated in the lower levels.

Mr.. Neill then exhibited several hun
dred samples taken from the mine by
himself and Mr.. Kennedy and the as
saws of which Steve Raymond testified
to be correct The description of the
i samples required much time. The wit
ness said he did not take a single SAM
pie all through the mine which did not
contain value of some kind. This
shows that the entire zone is mineral

plan and model, went all through the
| mine showed the sample taken from
each portion of each level, cross-cut,
drift. raise. etc, and what II assayed.
The effect of all the samples was to
show plainly defined foot wall tied
by innumerable pay streaKs To an
equally well defined hanging wall.
There are between the walls masses of
granite and porphyry which are not
pay ore, but all are impregnated with
mineral and the general characteristic
of the lode is concentrating ore.
A sample of rock was shown by Mr.
Neill taken 105 feet from the foot wall
and close to the point of contact be-
tween the granite and porphyry \
sample OF porphyry taken within IL
feet of the granite sample was also
shown. \ characteristic of the coun-
try rock outside the lode in the foot

are black specks of mica and seams OF

lode. The country rock granite is com

An exhibit was shown from the faul

witness thought the fault came from
the naturalization. From all he hat
observed in the ground. the witness
gave the opinion that the ore bodie:
under the Michael Dewitt are part o
one lode and that the Rarus. HI
could not conceive how il could b,
otherwise from a geological. chemica
or meteorological standpoint. 1t would
not be possible To separate any slice
from the lode and give it separate
identity.
