OWYHEE MINES.
Salt Lase Tribune.

the famous De Lamar district in Owv-
nee county. All the mines were
found to be in hourishng condition,
and being worked for all they were
worth. Sixteen bars of bullion, weigh
ing IN the aggregate, 25,740 ounces,
were shipped from the DE Lamar
mine last week. The assay value of
these bars has not been made public,
but the fact is well known that the
shipments from that mill run over So
per ounce, SO it is safe to estimate
the pments- thirty days run of
the mill-at $4,000. The amount of
hlgh-grade ore shipped in sacks is
SAID to have slightly exceeded that of
the previous month, so that the last
month OF last year has proven the
best producer of any month since the
mill started. At this rate there will
be no necessity of drawing on any re-
serve fond to pay for the construction
of the new S750,000 mill contemplate
ed. Build it as rapidly as they may,
the current product of the mine will
pay for it.
The cleanup of the Leonard mill
last week, running on Phillips and
Sullivan ore, has placed to the credit
of that mine nine bricks weighing 100
pounds each, and assaying a little
over $40 per ounce. This is the last
ore that will be crushed from that
mine until the roads are open in the
spring The development work now
going on already assures much bigger
and more frequent shipments when
they begin again.
The Flint mill is still producing rich
concentrates, but not having been
constructed for the purpose for which
it is run, there has been good many
delays and otoppages. Enough has
been done to prove that the ores of
that locality can be cheaply and prof
itably worked into concentrates, and
that with cheaply constructed concen-
trating mills to work the large guam
titles OF ores found in that camp, it
has bright future in store.
The story of the striking of the
Black Jack ledge by the daho-Pitts-
burg Company, who have been run
ming tunnel through the very heart
of Florida mountain since early last
winter, has caused no little excitement
in that district. This company start
ed a cross cut tunnel more than a
year ago to cut the lodges on theiI
claim at depth of 7j0 feet. This
was big undertaking and consider
able of venture, as no claim on thai
mountain had been developed to hall
that depth (many having doubts abou
the lodges going to any great depth
and the tunnel by measurement woulc
, have to be run in about 1000 feet. A
, steam drill was put to work and abou
1000 feet was run, in which two ledge
were struck, neither of which pros
! pected enough to pay. The company
then very much discouraged and ou
something near 100000, brought ex
, perts to examine the ground and upol
, their advice concluded to run the tun
f no further, but to drift on one of tn
: lodges that had been crossed. Thi
}, was done for short time with sue
n discouraging results that the orde
