ACTIVE DRILL WORK
At NEVADA DOUGLAS
Discloses Big Body Seven
Per Cent Ore in Casting
Copper.

Following is the last report OF tht
nine superintendent concerning the dia
nond drill work now being prosecuted or
he Nevada Douglas properties.
The last hole we sank on tho Cast.
ing Copper surface, which was dia-
mond drill hole No. 16. encountered
ore at a depth Of seventy-slx feet
and ian through the ore again into
limestone at about ninety-slx feet
The drill cores from this ore were all
mala chitc. and the average assay
value Is about Z per cent. This hole
was sunk about sixty feet south and
cast Of drill hole No. 12, In which we
encountered ore some time ago. Wo
nave been driving a drift from a
point twenty-one feet below the 100
level to intersect the ore cut in dia-
mond drill hole No. l6. and have beon
running In shipping ore practically
ten feet TO go before the orc Will have
been encountered.
Tho Casting Copper ore body seems
TO lay quite fiat. with only very
slight dip to the south and cast but
we are continuing TO develop new
punches of oXldizcd ore OF good
grade as we push our development In
that direction OF course, we cannot
tell what the future will bring forth,
but 1t Is not improbable that we will
ilnd some good big ore deposits lying
in chambers back underneath the
limestone hill.
We are continuing 10 average about
two cars a day from the Casting Cop
per. This orc Is running a little bet
ter than s per cent on the average,
and we ore getting one car every two
or three days from the Ludwig, which
Is averaging between Z and per
cent, Most OF the orc from the Lud-
wig Is coming from the 400 stope
above the shaft, the 3I5 stope. and a
new place which has recently been
opened UP south of the old il2 stope.
This ore is continuing to make out
along the contact between the lime
and the intrusive, IN the extreme
here is about ten feet wide, and OF
very good grade. AS the country
ahead of this Is practically all uneX-
plorcd along this contact we are in
hopes Of being able TO take out con-
siderable ore.
The diamond hole which is
being sunk on tho S0o-foot level of
the Ludwig started in the 500 cross
cut about thirty feet back from the
msin level, This hole was sunk In n
southeasterly direction, running down
at an angle OF about A. degrees, and
was intended TO prospect the terri
tory Immediately beneath the Stonc In
which we obtained The high grade orc
on the 500 level. The hole has prog
ressed about 80 feet; the last 100
feet has been running through a
mixed lime and quartz. running about
per cent in copper. The objective
point. where the richer ore should be
encountered. has not vet been
reached, but we expect good results
within the next Twenty-Five feet
While recent development work mas
been productive OF only a moderate
amount of high grade ore. We have
succeeded in developing quite a good
ly tonnage OF low-grade material that
should be very valuable 10 us when
we get our teaching plant started.
This is especially true In the Casting
Copper, where we found. almost all
of the oXdlzed shipping ore under
laid by mixed primary and second
ary sulphidc. which is running from
p TO 81 per cent copper l think our
chances for developing low grade sui
phidc ores for milling purposes is all
most unlimited. The last week
showed a net earning over and above
all expenses. including bond interest,
taxes. etc. OF about $4,000. | am In
hopes Of being ahle TO improve this
during the ensuing week
