MENT SHAFT At UNION
Manager Thatcher Preparing To
Handle $50 Tons Daily From
the Union Mines
Elko Independent of July 20

Wines Company.
Manager Thatcher is planning to
sink a double compartment shaft on
his property. 1t is already down 40
feet and he is working three shifts
and making six feet a day.
The shaft eventually will have a
depth of $50 feet to reach the ore
vein. Stations will becut every hun
bred feet and crosscuts run to inter-
cept the r body.
The vein has a pitch of as degrees.
1t is a contact between blue lime and
dolomite lime. The shaft is being
sunk in the hanging wall of blue
lime.
At the second level the shaft will
be Is feet from the vein, and at the
third So feet. If the dip of the vein
continues as it is the survey shows
that the shaft should cut the vein at
$50 feet. 1t will take about three
months to sink this shaft.
The present output of the mine is
80 tons of lead ore per day. When
the new shaft is completed the pro-
duction will be increased to $50 tons
every "a hours.
Manager Thatcher is now employ
ing 40 men. If this ratio is main
tanned he will have about 200 men on
his payroll when the new shaft is
completed. The pay is $4 to $3.50
per day.
Senator Thatcher makes head
quarters in Elko and buys his supplies
here. He has offices in the Title
Guarantee and Trust building and
makes a trip about once a week in
his car out to the mine. 1t is 67 miles
from Elko to the Union camp by the
automobile road via Carlin and Pine
valley.
And what a wonderful mine that
is; Senator Thatcher has in his office
samples of the ore that run as high
as "a per cent lead. The pure oxide
of lead is II per cent metal. Pure
oxide is what painters use and it is
the ordinary white lead.
This ore from the Union Mines
has all the appearance of white lead.
1t is soft almost like chalk. All one
has to do is to mix oil with it and he
has paint. There is of course a little
silica and this purity impairs it for
commercial print without refining.
The Union Mines is an old prop
erty. 1t was worked 80 years ago
and a smelter was erected. There is
a Stag dump around that smelter
that has perhaps 500 tons of lead in
it.
Roy Thatcher is State Senator from
Eureka County and has lived there
about five years. Three years ago
he made a trip out to Union to ex-
anime the property. 1t was then
owned by w. S. Magee. There was
practically nothing in sight at that
time, the property seemingly having
been worked out.
But Senator Thatcher knew the
formation and liked it. He saw the
possibility and paid $25, 900 cash for
ten claims. Two of these claims are
patented.
1t was the 23rd of June a year ago
when Senator Thatcher obtained pos
session and since that time has con-
Quoted systematic development.
He has explored the mine to a
depth of 262 feet on the dip, which
equals a vertical depth of POS feet.
He has opened up an ore body six
to IL feet in thickness and the chute
has a length of $50 feet on the con-
tact.
The thing that pleased Senator
Thatcher was the contact vein be-
tween blue and dolomite lines. 1t
was like the old Aspen, Colorado,
formation where young Roy Thatch-
er, nephew of Captain George W.
Thatcher, once worked in the famous
Mollie Gibson mine.
The country rock at Union is
There is a porphyry in
trusion and this dyke is about 100
feet in thickness. 1t is from this
porphyry dyke that the ore comes
and its deposition has taken place in
the zone between the two lines.
The dolomite lime lies next to the
porphyry and is about 80 feet IN
