It is said that the loss in smelling does
not exceed two PR cents q the mesal,
whereas in amalgamating, the loss ire
quentiy fises to thirty nve per cent.
The cost of smelling a ton of ore
ranges from $12 to $24, averaging about
SIS. An important item in the expense
is the charcoal. of which 30 bushels,
worth from IS 10 - cents per buehea, are
required for every ton. The transpOrta-
ton from the mine to the refining works.
and the separation, cost SO (gold) per
ton; and the lead sells for $40 or $50
per ton at the refinery; SO the total net
yield per- ton Of base bullion is about
$3.50, OF $45 per ton Of ore. The district
has II furnaces, of which are not run
ming. The idle furnaces are those of the
Ruby Consolidated, capacity about ~
tons per day; Rosalind, 80 tons; Bull
wbacker, II tons; Jackson, two furnaces,
each of IL tons; and Old Buttercup, two.
each of IL tons. The active furnaces are
five of the Eureka Consolidated, OF 81
tons each; two of Richmond. each 40
tons; one of Ruby Consolidated, As tons;
one Of Phoenix, 40 tons, and one Of Sill
yer West Consolidated, so tons-making
$40 tons of ore per day, equivalent to
81 tons of base bullion. The Silver West
furnace is idle just at present, but IS soon
to commence on 900 tons of ore from
the h K mine, and will probably soon
have q large supply of ore from its own
mine. The furnaces mike continuous
runs, lasting from 40 to 80 days; and at
the end of each run mustbe refined, with
q delay of three days, and cost of 5000.
The small furnaces are improbable
and are idle; the large furnaces are &C.
tive, and if they had the capacity they
could get 100 toms of ore per day beyond
the present supply, so that the total ore
yield of the district would be 500 tons,
and the bullion-yield 3d. 900 per day.
The Eureka Consolidated, X. X, Rich
mond, Tip Top, Silver West and Look
out have large quantities of ore, though
some of them are not yet provided with
the facilities for cheap and rapid extznc-
ton. All of them hoist through shafts.
and most of them have not yet gone
down far. The Phoenix and Orange are
down 4OOfeet; the Eureka and Richmond
800, the Silver West 100. The latter mine
il preparing to extract its ore through a
tunnel, which is now in $50 feet and will
be extended 200 feet further, striking the
main vein about the end Of February, at
q depth of 30 feet below the present
workings, where about 600 tons Of ore
are in sight, according to the Superin-
tendent's estimates. At 100 feet from
the surface the ore in the main lode is ~
feet wide, and three other parallel veins
on each side have beel found on the sur
face, and SO far - examined by shallow
workings, seem to converge toward the
middle or Excelsior lode.
The only considerable lode of milling
ore inthe district is that of the Lemon
mine, but probably little of it will be re-
duced until tunnel 400 feet long. now
under way, shall be conpleted. A tun-
mel !, 400 feet long would strike the lode
800 feet below the surface, and as the
ore assays $3.50 to the ton, and the vein
is large and is supposed to be uniform in
dips and richness, the mine promises
much. At present the Lemon mill of
fifteen stamps is engaged in working
about twenty tons Of ore daily from the
Gaddis and Bertrand mine in Secret Can
yon. This ore averages about $50 to the
ton, and before amalgamation is roasted
