October 16, 1886—Governor Hauser,
in a report to the Secretary of the Interior,
makes an excellent showing of Montana's
progress in mining and other industries
during the year past….
There is every reason to believe that the
products of our mines will steadily increase
from year to year until Montana stands reli-
ably foremost among the States and terri-
tories as a producer of the precious metals.
The Alice mine has erected fine new
hoisting works at an expense of $12,000.
A new steam stamp has been added to
the Anaconda works, with a capacity in
operation of 250 tons of ore a day. The ore-
crushers, which have been stationed next
to the ore-bins, have been taken down and
out, and will be used in another place. The
old concentrator building has been
changed materially. The company is at
present rebuilding the chutes at the St.
Lawrence mine as well as the Anaconda.
Large amounts of lumber are daily hauled
to the mine for that purpose.
The Blue Bird mill goes steadily on at a
cost of $250,000. The company has also
erected hoisting-works at an expense of
$40,000.
…a very rich but singular discovery bas
been made in the Lexington [mine]. It has
always been a silver mine. For ten years, it
has been a producer of silver ore. On the
800-foot level, where prospecting has been
active of late, and where a chute of the
usual character of ore was expected, a body
of distinctively copper ore has recently been
struck. The size of the strike has not yet
been developed. The ore is a pyrites of a
bright and beautiful color, and assays from
25 to 30 per cent copper and about 80
ounces in silver. Of course, it can only be
treated by smelting: The discovery dispels
the idea that copper may not abound at
great depth under all the silver mines in the
vicinity of Walkerville. The freak of the
Lexington is as interesting as it is important.
The Automatic Air
Compressor
September 4, 1886—Mine operations and
tunnel-boring are not usually accomplished
by the aid of automatic machinery, owing to
the peculiarity of the work and crude appli-
ances presented. Operators and contractors
have not taken kindly to machinery that very
soon proves to be more expensive than the
