GIROUX PLANS TO
OPERATE HEAVILY
Preparations Near Point of
Drawing Upon Alpha
Rich Ore Body.

Preparations for producing ore from
the Alpha shaft of the Giroux Conson-
dated company, according to advices
from Ely, are progressing rapidly. The
ere bodies opened through the Alpha
shaft are i'm limestone, and the gem
Cral average values on the 1.000-fOOt
level are said to be better than 20 per
cent copper. A Wine which is down
$50 feet from the / ,000-foot level is all
in ore, the major portion. OF which is
native copper. ore produced from
these workings is to be shipped TO the
International company's smelter at
Tooele.
While the ore bodies have been
opened in the Alpha shaft. they are to
be mined through the company's new
Giroux shaft. which is five-compart-
ment, and is down 1.2OO feet A sta
ton 125 feet long and twenty-five feet
wide has been cut at the 1,2OO-fOOt
level, and Il is being lined with con-
crete. Two pumps. one Of the capacity
