BOULDER COUNTY GOLD
THE TAMBOURINE NINE.
Cyanide and Roasting Plants Make
LOzo Grade Ore Valuable.

What would you think If some one were to place
in your hand d piece of rock irregular in shape.
measuring not than three inches in length
and two inches width. studded all with tiny.
gstening specks of yellow, and tell you in
versational tone of voice that ton Of the same
kind of rocks is worth anywhere from $4,000 TO
10000? Very likely you would do the natural
thing and become interested and possibly curious
to learn what it and from whence it came.
IF you could 60 TO Colorado, from whose noun
tains there is taken daily gigantic fortune in Just
such rocks you would see the mines which produce
the yellow metal which becomes golden eagles. The
State of Colorado is dotted throughout the noun
tain districts with snnokestacks surmounting the
surface works of thousands of mines. which day in
and day act the allies of uncounted throngs
Of men who spend their lives in delving into the
heart of the earth for virgin gold.
In no part Of this state there more mines or
greater riches than in the territory Denver,
Boulder and Pueblo. The hills in this section OF
the country are tapped by the Colorado & Southern
Railroad which carries the mines the materials
and supplies necessary for mining and development
work and starts the containing the gold on its
way TO the snelters where it will be reduced.
Prominently to the fore in the list of mining and
development companies in the neighborhood of
Boulder is group whose activities consist in min
ing for gold. is the Tanbourine mine one of large
group owned by the same management Then there
are the Livingstone, the Logan. the Yellow Pine
the Ingram. the Emancipation, the Smuggler, the
Richmond the Wood Mountain, the Lucky Star and
scores Of others adjoining or contiguous the
Tambourine mine, which is on Melvina Hill. near
the city of Boulder.
Boulder County is reputed to be of the rich
gold bearing sections of the entire state and the
only reason it is not better known q great gold
producing county is found in the character of the
ore which up this time has been difficult
treat With the erection of cyanide and roast
ing plauts the difficulties which beset the pioneers
in this section have been overcome; and the cost
Of the treatment of the ore, which was the big
problem confronting the men at the head Of the
mining industry the Boulder district, has been
brought to a level where mines producing of
valuation as low as 81 ton may now be operated
at a big profit
One of the first mines in this section utilize the
cyanide process in the handling Of the low grade
ores was the Tambourine, in which several New
Yorkers are interested among them being W T.
Winternlute who is largely responsible for recent
activity in this district The installation of cyanide
plants for the treatment Of low grade ores IN the
Boulder County district marked distinct step in
advance for not only Is the section prolific in the
higher grade ores but there is spot in the
try where profit bearing low grade ores occur In
more abundance than here.
In every gold mining district of the country
millions Of dollars been realized in profits,
by cyaniding the immense piles Of ore which
had been dumped aside as valueess. because
of the expense involved in eytricating the gold
which was there Therefore, in many cases,
attention was given only to the high grade ore.
yyhi could taken out easily ana give z pro1t
TO the rainel. The Boulder section OF the state
abounds in veins containing not only the highest
grade Of gold bearing orr, but also immense de-
nosits of ore which worth millions now that
men know how 10 get the gold out at a cost which
leaves big margin Of profit
II is lust as that, great as has been the
DEVELOPMENT OF mining, there remain untapped
avenues Of wealth that will make the discoveries
IN 10 date seem small in comparison Cripple
creek district is the wonder OF the world. and
from present indications is going TO be dupli-
Gated in the Boulder County district. where each
dav finds richer ore discovered There is
,,,bo would be foolish enough TO hazard guess
m the ultimate OF the mines in this district
No matter where you go in this section you will
see the smoke arising from the stacks that tell you.
even before you come within sight Of the shaft
houses that more gold is being mined The
nal reader Is not interested in the cost of mining
II he has any interest at ALL it is in finding out
bow these men who accumulate vast wealth in deal

NE everything else that Is worth while progresses
in method and efficiency. The cripple Creek dis

r,arl. in mining and what made Cripple Creek
sar,ous will probably make Colorado the leading
- --oduoer of the world. and may do the same
for Boulder County.
