Keystone Mine
Starts Operations

ssone mine last week, under the
supervision of George Andretta,
who received message from j. A.
Goodwin, the general manager, to
commence clearing out tho lower
workings of the mine at once for in
spection. The president of this
company and an expert mine and
mill man are coming soon to ex-
anime the proposition and determine
the kind OF mill that will be re-
quircd to treat the Keystone ores.
1t is said that the Keystone vein has
twenty to thirty feet of good mill
ing ore and three levels have been
driven already for some distance on
the vein, which would give sufficient
ore to keep a mill running constantly.
1t is proposed to begin the mill
building whenever it is definitely
determined the kind of plant that
is required to treat the ore success
fully. The ores of the mine are
complex in character and consist OF
sulphides of lead, zinc and copper,
all of which are silver bearing, with
more or less gold contained in the
metallic contents of the vein. There
is no more ideal location for a mill
site than is seen ut the tunnel por-
tai. from Which all the ores mined
may be trammed direct TO the mill
as it is taken from the slopes and
mill holes opened in the mine.
The mill products, which will
consist of pure lead, zinc and cop
per sulrhides, from which all the
waste rock has been eliminated by
the milling process, maybe shipped
to the smclters, or furnaces may be
erected at the mine, to reduce the
conceutsnass 60 lead bullion or cop
pcr matt. The zinc concentrates,
of which there may bc large
quantity, may he sent direct to the
zinc reduction works in Pueblo or
Canon City.
The Keystone mine has the best
location of any property in this dis
trict, respecting transportation faciI-
tiles, as it is located less than one
half mile from the d. & r. G. rail-
way and from which spur may be
easily laid up 10 the mill and tunnel
mouth. An abundance OF timber
is within mile distant from the
mine and sufficient water for mill
ing may be had from stream that
passes over the Keystone ground.
Tn ease it should be desirable to put
up lead smelling furnace, a large
quantity of bog iron ore is deposited
over a portion of the Keystone terri
tory which may be. used for fiuXing
purposes. Coke may be shipped up
from the Crested Butte coke ovens
as it is loaded on the cars for trans
portation to other smelling works.
The proposition OF extending the
tunnel along the main Keystone
vein for thousands Of feet into the
big mineral zones of Mount En-
mons is one of great interest and
great possibilities.
It is confidently ybelieved and gen
orally conceded by those best ac-
ouainted with the Keystone and
Mount Emmons ore deposits, that
they arc among the most promising
ever discovered in the country. A
large deposit of ore similar to that
of the Keystone. vein has been
opened up in the Daisy mine on the
opposite side Of Mount Emmons,
which is generally supposed to be-
long the same ore deposition. Thous-
ands OF tons of ore were mined and
shipped from the Daisy property
but it had to be packed down the
mountain several miles to the rail
road for shipment. The U. s. Ex'
ploration company propose to drive
their Keystone mine tunnel thru ths
mountain and tap tho ore chutes al
along until the big bodies OF tht
Daisy mine and Redwell basin art
