FRANCO-AMERICAN
Obtains Recognition At the
Northern Arizona Fair

tended by demonstration in mines and
mining that had never before been man
ifested in the state. 1t was the keen
competition between individual mineral
exhibitors, the contest between one
county and another to be accorded the
coveted blue ribbon and the renown
which goes with the district to be sin
gled out as the winner Yavapai made
a clean sweep, and the Mayer field
therein came out with all the glory,
collectively and individually, the board
of awards being unanimous in their
judgement, and happily their verdict
was wholesomely acquiesced in by the
mining fraternity. The Big Bug Cop
per company went under the wire as
the winner of the first prize, its exhibit
of the chalco-pyrite of II per cent
content and the bornite ranging to 40
per cent, giving it supremacy as an in
dividual collection.
PREFERRED CLASS.
The Franco American, situated in the
same field, and distant less than mile
and half to the north, galloped into
the preferred class as a close second,
easily winning the prize for the biggest
and most varied of copper products
ever exhibited in the state, in which
such an elaborate as we'll as an attrac-
tive lot of the red metal family had
never before been placed before the
public. In this keenly contested race
there were over two score of mines
striving to ego over the top" but fort
flied as the Franco-American was with
a magnificent as well as a material
line of its high grade products, it was
justly proclaimed by the practical
miner, the observing operator and the
copper geologist as the premier from
all angles looked at. Its exhibit was
mounted on a five decked pyramid and
consisted of approximately 500 pounds,
showing the various stages of mineral
ization to the depth of only 125 feet;
and without any preconcerted effort to
salt the lot by picking out the high
grade, the massive nest of the product
being based on an average value
strictly, anG without asserting. There
was shown the cuprite of a 13 per cent
content, azurite carrying 19 per cent,
copper glance of IA per cent, carbonate
of 19 per cent, and suphides of as high
as 40 per cent. The entire shaft to
depth of 256 feet is carrying these con
ditions, altho operations at present are
confined to the first level in crosscutting
and drifting, in which latter zone a ten
foot ore body has been determined for
distance of approximately 76 feet. The
water problem is to be handled at once.

FRANCO AMERICAN IS A FREAK. and
which assertion is based on its astound
ing mineral makeup prevailing at such
limited depths, which when contrasted
with the average copper mine shows
that depth of from 800 to 400 feet
has been required to reach the zones in
which this property has solved very

situation that has baffied mineralogical
authorities and up to recently has made
this element skeptical and reticent. Blu

1t IS generally admitted that it's freak

plausible theory advanced. The Franco

and its ore bodies strike to the south

200 to 600 feet in the sulphide state.
Among its companions this theory is
now admitted as tenable, and that the
Franco-American, the key to the min

arise from the unquestioned determine
