COPPER KING FINDS
A NEW VEIN SYSTEM
SILVER-COPPER VALUES
Discovered by Diamond Drill

- INCE JUNE this year the Cop
per King Mining company at
Mullan, has been engaged in
diamond drilling certain portions
of their ground not prospected by the
lower tunnel workings. The work has

have been more favorable than ex-

Cut New Vein.
In the first place, three holes were
planned at an angle of 60 degrees,
drilling up from the tunnel level The
first two holes developed nothing. At
this stage of the work the manage
ment in charge decided to lower the
grade of the third hole to 45 degrees
This hole picked up the vein expected
in it's proper place, proving that the
other two holes were practically on
the same dip as the vein. After cut
ting the known vein system drilling
was continued as a mere speculation
prosecuting the formation, and at a
distance of about 100 felt from the
first vein the diamond drill crew en-
countered one if the surprises of this
interesting game. The diamond drill
entered a new vein system which
proved TO be about SO feet wide, show
ing values all through the drill core
in gray copper Assays of this drill
core and cuttings proved from to
"a ounces silver and from 1 to 6 per
cent copper Maps were carefully con-
suited and several mining engineers
were taken to the property, including
julius p. Hall, formerly county en-
gineer and for many years consulting
engineer for the Copper King.
Prove new ore Shoot.
The engineers Investigation result
ed in the discovery that the main
Copper King tunnel had passed
through this vein system at a point
where it was intersected by a fault,
and while it showed some mineraliza-
ton it was not enough to warrant the
belief it was the vein the company
was driving for However, the dia-
mond drill hole mentioned above
changed all this, and the engineers
recommended that another hole be
driven 500 feet from the discovery
hole at an angle of 45 degrees. This
work was done and the same vein
encountered within a few feet of the
estimated point In this hole the drill
core shows the vein about 20 feet wide
with slightly increased mineral values
over the first hole Another hole was
Immediately surveyed by Mr.. Hall
1000 feet distant from the No. p hole
and drilling continued, with the re-
suit that the same vein was encount-
cred with heavy flow of water at
approximately on the survey point,
and showing decidedly increased min
eral values in the drill core and cut
tings. Samples of the drill core from
this hole gave assay returns of 30
ounces silver, 3.5 per cent lead, and
5.4 per cent copper

this new vein system with a erosscut /
