COPPERFIELD, New, May 90.
The smelter returns from the small
shipment recently sent out from the
Hell lease on the old State Line
mine have been received and show
mat the shipper received SAT per
ton net, after deducting the usual
charges for freight, treatment, etc.
The returns are rather disappoint-
ing, owing to the known high val
ues of some of the ore, but can be
accounted for largely by the fact
that the lessee put a lot of lower
Grade ore from the dump with that
which was taken from the vein
opened up some weeks ago.
The smelter settlement sheet was
not available when the reporter
called and therefore the exact pro-
portionate values in copper, gold
and silver cannot be given, but they
were similar to the usual run of
Copperfield ores-the principal val
ues being in copper, with substan-
tial measures of gold and silver.
The vein from which the ore came
is the extension of the Nixon-Ne-
yada's No. 4 vein.
Owing to the non-arr1val of the
air hoist which was ordered weeks
ago, sinking ON the Wine on the
M vain Of thn Nsy0n- Navajo Of
a point 125 feet north of the shaft,
has been discontinued for the time
being, as the hoist is necessary to
economical operation. Most of the
kigh-grade ore heretofore shipped
from the Nixon-Nevada came from
The No. 1 vein and the object of the
Wine is to get below the leached
zone and reach the permanent
water level, where rich primary
solphides are expected to be found.
Hhe main cross-cut from the bot
tom of the shaft is now out 1900
feet and the face shows mineraliZa-
ton and a number of quartz
stringers.
In addition to the many up-to-
cate features for economical min
ing and milling which have been
introduced by the management of
the Engels Copper company-for
instance, the new flotation mill is
practically automatic from the time
the ore is dumped into the crusher
until the concentrates are loaded
i1to the railroad car on the siding
mature itself has helped to the
end that the ores may be mined at
low cost.
Timbering is an expense at many
mines that cuts materially into the
Profits, but at the Engels very lit
tie timbering is necessary as the
ground holds without it. At the
Superior, or lower mine, timbers
we're put in for the o~re-pockets in
the shaft and for the portal of the
tunnel. At the upper mine very
little more timbering was required.
Owing to the immense size of the
orebodies the ore is mined on the
caving system which, combined with
getting it to the surface through
tunnels, cuts the cost to the bone.
This particular method of mining
was first introduced by Jack Walsh,
who has been for years with the
Gunn-Thompson and Mason Valley
interests. A number of experts
told Jack it couldn't be done, but
Re showed" them and now the
system is used in many mines.
The Engels mine has had the ex-
perience common to some of the
best-it was turned down by nu-
nlerous experts who said it would
rot make good. For years it look
ed as if they might be right, but
when the geological formation was
understood, the road to big produc-
ton and dividends was short. Dur
ing the first year after the man
agement 'got onto the mine," there
