VAN DYKE SHAFT
DOWN zoo FEET
Good Progress Made On
5 Copper Property at
Miami, Ariz.

The Van Dyke Copper company,
which has been sinking It's double
compartment shaft on its property at
Miami. Ariz., for a little over two
months. is down a little over ESQ feet,
according to cleve Van Dyke. con
trolling owner. who was an FL Paso
visitor Saturday. A drill hole had
been put down. striking the ore at
1856 feet and showing up &c feet OF Z
percent copper ore. All work was
Stopped during the war, but the sink
ing Of the shaft was resumed a little
over two months ago.
we are making about 80 to 100
feet a month in depth in our shaft. ."
said Mr.. Van Dyke. and we are drill
Ing With what is called a bull point
drill not using any powder. This
kind OF a drilf works well in con-
giomerate, which we shall have to
work in for several hundred feet yet
Our drill hole was put down with a
California rotary drill used for drill
ing for oil. 7 get II in California and
feet The derrick we used was LOG
feet high
Devised New Drill.
~Of course that rotary driI could not
take 4 core when we struck the ore
so we had 10 devise one That was
the rub. Ny brother. Pat Van Dyke,
had worked as a helper In a surgeons
office at one time and he remem-
bered the trepanning drill used there.
II was hollow drill beveled inward
At the sharp end and II brought out G
core OF skull bone Pat said he was
sure a drill built on the same prin-
ciple would work as 3 bit for our 70
tary.
So we made one Of tungsten steel
and Il worked We could not use any
water in getting that core with our
newly devised drill, but it brought out
and the heat from the friction in the
copper ere (-z7 water having been
used had FURNISHED the four foot bit
with metallic copper There WAS no
doubt then that We had struck the
copper deposit. We found &c feet Of
Il running percent COPPER
I had believed that I had in the
1900 acres of ground OF my company
tne same deposit that was in the
ground OF the Miami Copper COMPANY I
and the Inspiration Copper company, !
where they had proven deposits con-
tanning 10000. 600 tons
GtologiSts Differ.
But there was a fault about the line
OF the Miami Copper companyis prop I
erty and al biologists but one I
claimed that fault was made before !
The copper IN the property Of the two ,
companies above mine was deposited.
This one believed with me that the /
fault was made afterward and Just {
cut the deposit in two ard that my
company had the continuation Of it
had ny rotary put to work at
point right in front Of the way the
Aiarai Copper company's ore was
coming as old John Davis. an old time
prospector who had studied that dis
trict told me. BE said we would
strike the ore at 1900 feet and lie
vas off but - feet
The biologists who had persisted
that the great copper deposits OF the
Miami and Inspiration companies had
cen cut of from my ground by that
fault have been doing some explain
Ing ever since
7 believe our company has a big
deposit OF coDner ore Where VIC
struck Il with The drill Il was IS feet
II much higher grade ore than that
~ the two companies named. I firmly
believe we have what viii prove 70
be the same with relation % tho
Iiaui and Inspiration as the United
Verde Extension did TO the great
nited Verde At Jerome. Ariz. and the
and Arizona did 10 the Cop
