Engineer Submits An Interesting
Report to Manager of Me-
vada Property.
REFERS TO THE LUDWIG NINE
Says Condition Is Satisfactory--An.
ticipates Splendid Results from
Work Planned.

e. p Jennings. of the engineering
staff of the Nevada Douglas Copper
company, who returned from a trip to
the properties of the last named cor
poration few days ago, has submit
ted his report to the manager. Walter
c. Orem, and in it he describes the
work done and developments made In
the Nevada Douglas and Ludwig mines
since his previous reports, which came
out in December of last year and in
February of this year
THE ore bodies of the Nevada Doug
las" says Mr.. Jennings, occur in
three separate areas Of garnet rock;
the largest being that known as the
Douglas Hill The second body Is
southeast of Douglas Hill, and the third
body extends from Douglas Hill south
westerly for 1000 feet.
For the purpose of developing this
latter body, together with the Douglas
Hill area, working tunnel by feet
In cross section was started at the
southwestern edge of the third ore body
last yeaE and has been advanced in the
direction of Douglas Hill GOO feet and
will eventually tap the ore bodies at 4
depth of 500 feet. One thousand eight
hundred feet still remains to be driven
to bring the face of the tunnel to a
point under the main openings on Doug
las Hill,
The first 100 feet of the TUNNEL is
in limestone: at this point garneiferous
lime began to appear which contained
small amounts of oxidized copper ore.
AS the tunnel was advanced the ore
gradually increased in amount and
body of per cent ore, 40 feet wide.
was encountered. BEYOND this ore
and to the face of the tunnel a dis
lance of 400 feet, the rock is garnet
containing small amounts OF oxidized
copper ore.
"a shaft has been sunk 30 feet to the
left of the tunnel and $50 feet from its
entrance, on per cent copper ore to a
depth of 1870 feet. At q depth OF %
feet the shaft was connected by a 30
foot cross-cut with the tunnel; this
oross-cut has been driven to the right
of the tunnel 40 feet and a winze 30
feet in depth sunk at the junction of
the ore bearing garnet and the eastern
white limestone. From the bottom of
the Outside or 130-foot shaft, a drift
has been advanced 10 feet in 5Ia per
cent sulphide ore. The Outside
shaft, cross-cuts and 30 foot winze are
all In ore.
1T is proposed to advance the drift
from the bottom of the Outside shaft
northerly. following an ore body which
has been traced and partly developed
by the S. S. shaft and other shallow
pits for a distance of 600-700 feet. An
other ore body has been traced and
partly developed by shallow workings
that has a northeasterly direction and
following a Limestone contact
for 1000 feet This body Is being de-
veloped by drift beginning near the
winze in the 40 foot cross-cut. These
drifts are the most important work now
being done as they will place a large
amount of ore in sight The width of
these ore bodies is from 100 to 200 feet
and the garnet between them, will I'M
doubtedly contain low grade sulphide
suitable for concentration.
"A three compartment shaft has been
sunk near the entrance of the tunnel
to n depth OF So feet for the purpose
of developing the ore bodies at depth
This viii be continued on the compile
ton of the air compressor ana hoist
Ing engines.
"A tunnel 60 feet In length, known
as the 'Porphyry ridge" has been
driven on n streak of ore at the juno
ton of n granite porphyry dyke and
the metamorphi limestone, and the ore
has been followed down for a depth of
80 feet in an incline Wine. This
ore is OF interest. as 1t is the only por-
phyry lime contact that has been de-
veloped on the property"
Referring to the Ludwig property,
Mr.. Jennings declares the condition OF
the property is very satisfactory and
recent developments there have been
unexpected. He adds that It is i'm
possible to predict the size of the sui
phide ore body, but judging from the
length of the outcrop II will probably
be at least 600 feet long and from 20
to so feet in width. Mr.. Jennings be-
lieves In the bottom of the Ludwig to
be a good place TO drive into Douglas
hill, as 1t WIN tap the ore bodies 525
feet below the deep tunnel now being
driven.
II see nothing from my recent exam
nations says Mr.. Jennings in con-
clusion. ito change my opinion as to
;he amount or value of the ore in the
Nevada Douglas mine; the work. as far
az II has been done is satisfactory In
the amount and quality of the ore dis
closed, and II 1t is continued as now
planned the amount OF ore in sight
six months from now win be very great.
More ore could have been put in sight
quicker by combining the work 10 Doug
las Hill, bur then the deep level tun-
mel would have to have been driven TO
