Mines Of MANHATTAN DISTRICT
CONTINUE ACTIVE development
Manhattan Cha amber of Miness

nv wv We
fifth level of the White Caps has
advanced all in ore a distance of
80 feet for the week, the ore carry
ing average mill values in gold. The
highest grade ore in the shaft ore
body of the White Caps is found
next to the hanging wall of the
vein, so that the present values
demonstrated will no doubt improve
when the hanging wall portion of
the orebody is explored.
The present grade of ore though
is considerably higher than the
similar section as shown from the
level above. This was anticipated
from developments in other portions
of the mine in the east orebody. The
shaft orebody will not be cross-cut
until a raise is extended through 1t,
as due to it's flatness, a raise will
prove the various portions of the
ore, from footwall to hanging a
great deal faster than from lateral
work.
Other development in the mine
consists of 5O4 raise in the east ore
body extended from the fifth level,
which made the regular weekly
footage. A streak of low grade ore
was encountered in the past two
days in the raise work, the balance
of the raise being in very good mill
ore.
New work in southwest cross
cut No. 512, being extended from
sos sill towards the hanging wall
of the ore of the fifth level east
orebody. This cross-cut has now
demonstrated a footage of ~ feet
of medium grade ore to be added To
the width of the sill or a total dis
lance across the ore of Az feet, with
no signs of a hanging wall yet.
The east orebody has now been
proven across the ore from the foot
wall with three cross-cuts, the other
two showing "a and 80 feet re-
spectively but none have yet
reached the hanging wall of the ore
body. The present work is to be
continued until the true hanging
wall has been demonstrated, SO hat
the exact width of the ore can be
measured. Ore for the weeks mill
ing has been taken from 406 stope,
612 cross-cut, 504 sill.
The semi-monthly cleanup from
the mill has just been completed
and has proven most satisfactory
as it is considerably larger than any
previous clean-ups, and the bullion
D, ives to be of higher grade gold.
1t can be understood why the
cleanup is larger when it is Co..
sllered that the mil heads haze
been raised during the past two
weeks milling, bringing the aver
age extraction just that much
higher in percentage, as the mill
tails remain constant in value.
Manhattan Consolidated
The southeast cross-cut on the
fifth level of the Consolidated has
now reached 1876 feet in distance
from the station, the weeks foOtage
being SO feet. The rib of hard
quartzite has been passed through
and the last ten feet OF the work
has been in soft shale. 1t is OK
pected that the limestone which
contains the east orebody will ;.e
encountered in from 20 to 80 feet
more distance.
ihe bedding panes of the for.n&-
ton have flattened much more than
as shown from upper levels and for
that reason it cannot be expected
to reach the limestone in as short
a distance as from the fourth level.
Directly against the q%uartzite reef
passed through a vein of white
quartz five feet in width was cross
ed and the vein proves to contain
low gold values.
The same level was crossed in
driving for the east Orebody from
the fourth level but there it was
smaller and carried considerably
less gold content. This vein will be
prospected later, after the east ore
body has been opened up, as quite
likely an ore shoot can be found
therein. Mention should be made
of an important orebody thai has
been explored lately from the 500
] level.
This is known a the mud vein,
south from the shaft, and has been
drifted upon for so feet, and
in the face of the drift a full eX-
