JUMBO SHIPPING
100 TONS DAILY
PRODUCTION WILL BE GREATLY
INCREASED WITH VELVET
SHAFT In USE


The Velvet or No. shaft of the
Jumbo Extension has passed the
7GO-foot point. and within a short
time connection will be made with
the east cross-cut from the Pato-
verde workings, at depth of ap-
proximately 100 feet. This will af-
ford better ventilation and will serve
to facilitate the work of sinking.
The shaft, at it's present rate OF
progress should be completed in jan
uary, making connection at the lOli-
foot level with the cross-cut now
being driven, affording Immediate
access to the main workings in ore
through the shaft and rendering 1t
possible to at once double the pro-
duction of the mine.
In the eastern part of the Velvet
claim, development work continues 10
meet with satisfactory results in ex-
ploring the shale contact Ore-chan-
mel. The 535 drift has been pro-
crossing in ore of excellent grade,
the full face averaging at times wei
above 500 per ton. This DRIFT was
started from winze below the east
ern extremity of the rich 524 DRIFT
and extends farther east, proving the
continuity of the rich ore toward the
eastern boundary of the Velvet
claim.
Still farther east and within 200
feet of the side-line, the $50 drift,
extended in a northeasterly direction
from the raise above the 10l7-loot
level. has progressed for over 200
feet in shipping ore of high uniform
grade, and the 555 drift, north
branch of the $40 has been showing
ore of even better quality. This ter
ritory has presented some puZzling
condit'o ons at times, owing to the
pronounced irregularity OF the
shale's surface, rendering it 'lifti-
cult in places to determine the
course that must be followed by
drifts to remain in the ore-channel,
but this difficulty is not serious
one and has been overcome at other
points.
Ore of excellent grade is coming
from the 541 and SAG slopes, opened
from drifts that have been extended
above the 524 and at a. depth of ap-
proximately $40 feet. Some high"
grade ore has also been broken
lately in resuming work to eyterd
the old SIS stope, near the top of
the 5O3-A raise, near the Paloverde-
Velvet boundary. A crOss-cut is
now being driven at about this depth,
from the main Paloverde workings.
in order to facilitate the cxplora-
ton of this territory and the extrac-
tion of ore found at the contact
above the 524 drift.
Shipments are now going forward
to the Western Ore Purchasing com
pany's sampler at the rate of over
100 tons daily. the average value of
the product being slightly lower than
formerly. This has resulted from
breaking lower grade material in
stripping the slopes on deeper levels,
where the ore near the walls is OF
too good grade to abandon to cav
ing and not sufficiently valuable 10
justify heavy timbering in order to
protect it for future extraction. In
this manner, these Slopes are oleaI-
ed of all ore of any appreciate value
and are filled with waste from de-
velopment work and permitted to
cave. During the present month the
stockholders of the Jumbo Exten-
sion company will receive checks Tor
the dividend of 10 cents per share.
