THREE-MILE TUNNEL
TO OPEN MINES

Competent engineers declare that
the threc-mile tunnel to penetrate the
mountain between Greenwood and
Phoenix, B. c.. upon which the pre-
liminary work is now under way, Will
provide practical means of extracting
ores at great depth from numerous
properties, and they predict also that
ii will open possibilities TO merit the
attention of the mining world
The bore is projected by the Green
wood-Proenix Tramway company OF
Chicago. TO which the taxpayers OF
Greenwood have just voted a bonus
Of $4,000. to be paid In three install
ments. as follows: $4,000 at 1000
feet $4,000 at 5000 feet and 1000
when the city limits Of Phoenix arc
reached. The first section is to be
completed November /. 1911 New
York and Chicago parties have under
written bonds 10 the extent of S3,-
100000, which is the abount required
to construct and equip the tunnel.
Compressors and electric drills are
being installed at the Greenwood end
of the tunnel and 1t Is given out that
construction work will begin in a
short time. As the undertaking does
not involve any unusual engineering
difficulties. it is believed that rapid
progress will be made from the start.
The tunnel will be large enough To
carry 10000 tons of ore daily, and
beyond the first section II will carry
ore on a tonnage and freight basis.
1t will also be tramway for the car
rying of ores from the various mines
contiguous to the route Of the bore.
Considerable work has already been
done on the mineraliZed zone which will
be crosscut by the tunnel, and while
this has been expensive the value of
the ore Is estimated at more than
100000 This gives an indication OF
what may be expected when the belt
is bored In systematic manner. The
exploring at the Greenwood and
Phoenix, camps 10 the depth of more
than 1000 feet will start deep mining
in the boundary district, and the re-
suit Will be the operation of proper
ties with showings Of gold and silver

The company considers itself for

ore, averaging better than 500 ton,
have been shipped from this belt, but
the operation was expensive, the min

Announcement Is made that the tun-
mel company can easily reduce the
cost of mining TO $40 a ton BY the
consolidation OF the properties and the
deep tunnel, while the freight and
smelter charges will be not more than

there will be sufficient ore to war
