Owyhee county will soon be famous
again as bullion producer:
| Capt. De Lamar started his mill a,
this place on ore from the Wilson
mine during the week. He will
keep 1t running steadily for several
months. There is any quantity Of
good ore in the Wilson mine, and il
will not be for the lack of ore if the
mill shuts down.
The Lincoln mill having been pur-
chased by ]. H. Brotherton, of Lon
don, is now undergoing repairs under
the superintendency of Mr.. Leech,
and will soon be in excellent condi-
ton to reduce the ores from the
Psorman group of mines. We un-
derstand that concentrators of the
same make as the one in use at the
Leonard mill will be placed in this
mill.
The Leonard mill is now running
on rock taken from the dump of the
Gro Fino, to test the practicability of
working the ores of this camp by
concentration, a Black Hawk con.
centrator having been put in this
mill by Mr.. Leech, the Oro Fino su-
perintendent, for this purpose. 1t is
a pronounced success, and promises
to Immediately revolutionize the
methods of working Silver City ores,
as we'll as to give tangible and con-
siderable value to every ton of more
than hundred dumps on War Eagle,
Florida and other mountains herea
bouts. The concentrator now at
work rapidly reduces fifty tons of ore
to one without leaving the tailings
any richer than when worked by the
former, and many times more expen-
sive pan process. 1t is thought that
many of the ores may be reduced
still lower than this. Most of the
mines in this vicinity carry a small
per centage of chlorides of silver, so
fine and light that it has been found
almost impossible to save them by
amalgamation; this is lost in the
concentration, but as this loss has
always practically occurred anyway,
it cannot be charged up against the
latter method of working.
Mr.. Leech is confident that he will
be able to keep the cost of working
Orc tino ores by this method below
two dollars per ton. According to
the ancient history of this and other
mines in this camp, the cost of work
ing them when the greater part of
the mining was done, was not less
than forty-fve dollars; consequently
the slopes are full of, and the dumps
abound in ore, large portions of
which run close up to that figure in
Falue. Assays of the Orc Fino dump
make it fair to estimate its value
close up to twenty dollars per ton.
Several other dumps, where they have
lot been ''sluice mined," are probably
equally valuable. Placing the value
