ha
artment affair, is going on steadily.
r.o water flow for the last three
..ots has remained about the same
that is about sixty gallons per
mnute-which the pumps handle
u#h ease. The shaft was extended
,hirteen feet during the past week
and Is now down a total distance of
ts5O feet from the surface. The
,ormation shows no change, the bot
tom continuing in rhyolite-dacite. In
Ill 4471b feet of development work
vas done in the Tonopah Mining
workings in the seven days. The
Nizpah side Is credited with 276 feet,
silver Top with 11Sh feet and the
Red Plume with fifty-three feet. The
shaft on the latter was extended
twenty-five feet and is now down 552
feet The formation at the bottom
continues to show porphyry. Con-
trary to the report published in an
afternoon paper that the diamond
drill on the 74O-foot level of the Sill
yer Top had encountered ore, the
oicials of the company state the re-
port is a canard of the worst type.
