MARKET GUARANTEED.
M. Poulot. on the strength Of his an
alysis, has guaranteed market at Grand En-
campmcnt. Wyo.. for all the ores Of cobalt that
can be produced In that district from this
time on
THE ores tested for cobalt came from the
famous Doane copper mine at Grand Encamp-
ment, Wyo.. at a vertical depth Of III feet
where it is found to contain per cent of CO.
bait NJ. Poulot in passing his opinion upon
the conditions Of the cobalt as It occurs in
the Grand Encampmeft ore. says it is the re-
suit Of his experience in handling this mineral
that it occurs in greater quantities in some OF
the lower grade sulphide copper; but in that
event it might possibly contain more arsenic
which would render its chemical reduction
somewhat more difficult, and detract possibly
from its market value.
The cobalt as found at present has a value
Of 81 GO per pound. or SD per cent This would
make the assay value Of the body at pres
ent exposed in the bottom Of the DOane shaft
4 per cent cobalt. SIPS: 20 per cent copper at
$50 per unit, Sl05; total S223 per ton. As it is
an Acknowledged fact that 16G tons OF this ore
have already been shipped to Chicago ayerag
ing in value 10 per cent in copper from grass
roots. and admitting that but per cent cobalt
were contained in that product. the amount OF
81 ,2iS has been absolutely lost, as no return
for any value aside from copper has ever been
received from the shelters.
In the recent reports made by Mr.. William
Weston. Of London. England and myself on the
Grand Encampment district it will be noted
that We dwet strongly upon the wonderful cop
per as we'll as gold showings there existing; in
fact. in my report | dwelt somewhat lengthily
upon the peculiar and satisfactory geological
conditions that were found there. favorable to
the existence of copper in large quantities., and
here repeat that in good faith consider it an
established fact that in the near future it will
be recognized as the greatest copper producer
Of America: and further. in all Of my varied ex-
reriences in gold camps in different countries.

EASY TO GET AT.
The country suffered SO lsrgely from erosion
during the Tertiary period that the various
folds Of the formation were left bare. with the
quartz veins cropping so plainly that prospect
ing can easily be done on horseback No man
need make location with any doubt Of having
discovered vein in place. Each man can be
his own assayer. for pestle and mortar and gold
pan will prove to him at once the value Of his
discovery.
"As matter of practical information TO pros
pectors looking for the ores OF cobalt in the
district l would state that the varieties most
probable to occur would be absolite. which is
earthly variety and an oxide that generally con-
