ing 210O tons, the Tonopah Extern
sion 23SO tons, the Jim Butler 700
tons, the West End $50 tons, the
Rescue PSI tons, the Halifax 100
tons, the Montana &c tons, making
the total production for the week
9461 tons, the estimated value be-
ing $175,O2S. This valuation is
calculated on the gross milling value
of the ore.
The Tonopah Mining company
shipped to the smelters one of the
heaviest consignments of bullion
that it has made for some time. The
shipment consisted of So bars. and
the valuation placed upon it by the
officials of the company is $751;
500.
A continuation of the satisfactory
conditions which have been reported
weekly by the Tonopah Mining
company, is noted in the current
report of mining operations. The
work was inaugurated last week at
the 2OO-foot depth in the hanging
wall of the Valley View vein was
kept up at the usual steady rate of
progress, and the only change that
occurred was a l~essening of the
values, the ore now reported to be
of lower grade than was shown dur
ing the preceding week. The other
parts of the mine, where develop
ment and prospecting work are in
operation, received the same care
full and systematic attention that is
slopes in the Silver Top, the Miz-
pah and the ~Sandgrass territories
maintained their unusal respective
rates of production, resulting in the
shipment of 21O0 tons of ore from
the mine to the mill.
The report of mill operations for
the week ending April 7th, shows
that an average of &c stamps were
kept dropping and that 2100 tons
of ore were milled. averaging 500
in value.
Development work proceeded on
the vigorous scale that has been
shown in recent weeks, with an ag-
gregate footage of SIG reported. OF
this total, there vas 50 feet per-

ings, on the 9Th and 9th workings;
the Silver Top ground reports 40
feet as having been made during
the week; and in the S%andgrass
claim, the work amounted to III
feet.
The detailed report Of operations
is as follows:
At the Silver Top shaft workings,
on the 24O-foot level, the raise in
the hanging-wall of the Valley View
vein made the usual satisfactory
progress. The quartz upon which
this raise is being extended contin-
ues to measure between 1 and
IL feet in width, but the values
have fallen off somewhat since the
previous report was issued, and in
place of the ore being of milling
grade, the values returned from
assays show it now to be low grade.
On the 540-foot level, the usual
satisfactory progress was made in
extending the crosscut to the south
from the South Dipping vein. but
aside from the added foOtage there
has been no change of any character
noticed during the week. The face
of the crosscut continues to advance
in waste material. The good widths
developed by means of the stope
on the Burro No. A vein at this
level continued to be maintained,
yielded it's usual quota of milling
grade ore from a 4 to 5-foot face.
On the 640-foot level, raise 644,
in the fOotwall of the Burro No. 4
vein, was put up the usual distance
during the week, under conditions
that were substantially similar to
those mentioned in preceding re-
ports. The top of the raise is max
ing good Roadway against a 2-foot
width of quartz containing low val
ues. Operations in the raise in the
footwall of the South Dipping vein
we're discontinued TOT the present
at least, as So far there has been
nothing of any value encountered.
A raise has been started in the
footwall of the Valley View vein
where a streak of quartz about 1
food in width is being followed and
opened up to ascertain If something
more substantial will develop. There
has been no change in conditions
attending the prosecution of work
in the southeast crosscut east of the
shaft, which continues to proceed
through waste rock, nothing of any
value having been found in the
crosscut as yet.
Stopping work was continued with
out interruption on both the South
