DEVELOPMENT At
BOSTON ELY NINE
INDICATIONS THAT EAPLORA-
TION WORK WILL REVEAL
VERY LARGE DEPOSITS OF
HIGH GRADE COPPER ORE.

Local stockholders of the Boston
Ely Mining company will be interest
ed to know that some extensive de-
velopment work is now being carried
on at this property. The drift off the
1100-foot level is expected to show
some good ore deposits within the
year. The country now being pros
peeted is probably the most promis-
ing of anything attempted since this
estate was acquired by eastern peo-
pie, says the Salt Lake Tribune.
BY reason of its location and the
great interest that was manifested in
tho Robinson mining district several
ytars ago, local mining men sub
scribed literally for the first issue put
out by the Boston Ely company.
While there never has been any critf
cism of the management of company
affairs, there has been considerable
disappointment over the failure to
find large ore deposits of CONNER
cial grade. Just recently George l..
Walker of Boston was invited to in
spect the property and has the follow
ing to say:
Boston Ely's 1245-foot level was
flooded with water soon after Giroux
discontinued pumping in its deep
shaft in the Alpha area. The man.
agement considers it unwise to install
pumps and attempt to keep the work
ings clear. In preference to this the
1100-foot level drift is being driven
due west for the purpose of exploring
the ground on both sides of por-
phyry dixie which cuts across the
Emma and through the two Matilda
claims.
THE strike of this dixie is south
east and northwest. 1t is followed or
parallel by three fissure yiens from
the outcrops of which more or less
copper, lead. silver and gold ores have
been mined in the past. Unques-
tionably it is the most promising area
that Boston Ely owns, and rot few
engineers have declared it the best
prospect in the district. Tie plan is
to drive the 1t00-foot level drift into
this ground and then raise a new
shaft through to the surface. thus ex-
ploring the ground both laterally and
vertically.
This drift Is in 425 feet or more
already, is being driven at the rate of
about five feet daily and will get into
very interesting ground 400 or 900
feet further on. l found the drift in
thoroughly leached heavy iron-stain-
ed limestone when visited the prop
erty, and speeks of copper carbonate
were to be seen occasionally.
1T Is now the opinion of the best
biologists in the district that there is
great stratum of leached limestone,
standing almost on end, extending
from the Boston Ely property In q
semi-circle through the Alpha area of
the Giroux ground. Apparently this
limestone stratum has received the
copper-bearing solutium from a con-
siderable portion of the adjacent por-
phyry areas. If this theory is correst.
very large deposits of high grade cop
per ore will be found in 1t when suf-
ficent depth is reached.
THE greater portion of this leach.
ed limstone stratum is owned by Gi-
roIx and Butte and Ely. II the pro-
posed consolidation of these two and
other companies lead to the early
development of the Alpha area TO
great depth, this limestone will be
drained by the pumps in the Giroux
shaft and Boston Ely will thus be re-
lieved If its water problem.
