and n that has not so far proved fav-
orable. East of Columbia Mountain is
the Great Bend-Daisy belt. which is of
great promise. The country rock here
is later andesite. with prominent rhyo-
lite dykes. n high grade ore in COM
mercial quantity is found at depth.
Southeast Of the Daisy are two limited
surface areas of dacite, and the country
rock Of the lower Daisy workings are
also probably dacite.
Garry and Emmons state that the da-
cite mass in which are the great mines
OF the Consolidated company, appears
to be an intrusive sheet dipping gently
TO the west and south and cut off to the
west by f~aulting." This is a matter
that has not yet. so far as l can learn,
been determined. but upon which definite
knowledge is very important. If the de-
cite mass does not underlie the a1askite
and older andesite. shown in the central
part Of the Geological Survey chart, de-
yelopment in those rocks Is likely to
prove disappointing. If, as some geol-
ogists believe. the dip Of this dacite
mass is east, the payable area will prob
ably be much extended. No develop
ment Is yet deep enough to throw light
on this point. but a few deep bore-holes
would doubtless tell the story.

Opportunities for legitimate mining

selves to leasing. 1t Is not difficult for
any individual or company having the
required capital to obtain a lease on
promising ground. AS a rule from $780,
900 to $50. 900 is necessary; and until
nav ore is found. extensions are readily
granted, while a labor strike clause is
always included. The system has been
profitable to both owners and leasers
at Goldfeld. and so is popular.

veloped. that equipment Is. as yet. in
adequate and that practically no means
nave yet been provided for handling
low grade ores. Output is confined to
high grade. which represents but a
fraction of the total values already In
sight. The bonanza mines will be de-
veloped and thoroughly equipped with
proceeds of the rich ore. but the assur-
ance of long life and steady dividends is
found in very large and continuous
bodies of comparatively low grade ore.
Other mines. and not a few Of them. in
which no considerable bodies of ship

properties because they can be made to

Their is much misconception in re-

judicious puflng and equally injudicious
condemnation by journalists who know
nothing of mines or mining. Legitimate
operators who are used to ordinary
veins of ordinary value. find 1t dificult
to believe even conservative statements
concerning the bonanx mines. Personal
inspection win prove convincing to
those who know mines and ore when
they see them. The story is told in the
stopes-American Mining Review.
