MINES OF LUN|NG
DISTRICT ARE
PROSPECTING
PAY ORE Is BEING EXPOSED IN
MANY PROPER
TIES
(By James f. O'Brien).

some sorting, averages 20 per cent
as it is sacked, has been made on
the Dandy group owned by the For
nina Sarrias property at Luning.
The find was made on the lease of
Fermin Arrigia, who has made a
number of good finds on both the
Dandy and the Emma groups. His
latest discovery vas made close to
the surface a short distance above
where he has driven a tunnel into
the hill.
AS it is placed in the sacks the
ore looks rather uninviting, so much
so that the engineer of a nearby
property thought that the Mexican
lessee had overestimated the value
of the ore until he himself took
grab samples from the sack and
found that it averaged better than
90 per cent.
At another place on his lease, in a
cross-cut from the tunnel level. Ar
rigia has opened an orebody Is feet
in width. A visiting engineer recent
ly took a cold-blooded sample Of this
and found that it averaged 5h per
cent copper across the entire width.
A shipment is about ready to go out
from this point.
The Sarrias ground not only has a
good showing of its own, but 1t ad-
Joins or is close to such well-known
properties as the Calavada, Copper
Ridge, Wedge, st. Patrick, Luning-
Idaho and r. B. Todd mines. The
court has recently confirmed the OPP
ton given to Mark Walser Of the
Wedge company, who is figuring on
a merger and the building of a re-
duction plant.
At the Calavada mine the winze
from the 1OOO-foot level has reach
ed the 1165-foot point and is making
one and a half feet a shift. 1t is
now passing through a heavy gouge,
mostly a monzonite, with much sec
ondary pyrite, and occasionally ST.
licified punches carrying copper and
silver. They are only working one
shift on this winze on account of the
air. The northwest and the south
east drifts on the 1000 level made
the usual progress during the week
without particular change.
A report which was recently made
on the Calavada by Engineer Paul
w. Myers contains the following par
agraph: 1.-THE additional depth to
which it will be necessary to sink to
encounter unaltered sulphide ore is
of course unknown, but the evidence
of the 10O0-foot level leads me to
believe that the sulphide zone will
be reached within the mex 400 feet.
The chalcocite encountered indi-
Gates that a level low enough for the
appearance of a secondary sulphide
ore is just being reached, while the
occurrence in hard spots of pri-
mary sulphides, such as chalcopy-
rite and spalcrite, is strong evidence
of nearness to the objective"
At the Copper Ridge mine, owned
by George Giroux, steady progress
is being made on the winze which is
being sunk on the vein from the
260-foot level. The indications con-
tinue favorable for soon reaching
the water level and zone of primary
sulphides, which is the objective of
this winze.
Grab samples were recently taken
from the orebody on the 260 level,
carefully excluding what was obvi-
ously high-grade, and the assay re-
turns were seven per cent copper.
The conditions at this point are SIM
liar in many respects to those at the
1000 level of the Calavada, which
is nor than encouraging.
What is known as the Noone lease
on the Iroquois Copper company
ground has shipped two carloads of
ore, aggregating rs dry tons, and
received net returns of $2343.59,
after railroad freight and smelter
charges wer deducted. This is
proving to be one of the best paying
leases on the I~roquois ground. One
man for quite a time took out a ton
a day that averaged 9R per cent
copper.
The Luning-Idaho company is driv-
ing ahead on Stockham tunnel No. 2
through which will be developed a
sulphide orebody that looked very
promising in the upper tunnel. These
lower workings will give an addi-
tional 100 feet of backs and should
materially augment the tonnage from
this property.
