on the Alameda group of six claims
in the Whiskey gulch country. The
Alameda group is owned by Messrs.
McEvony, Sawyer and f. e. Wright,
OF Lewistown, and Is located south
and west of the Big Six group. On
the Alameda and Gladstone claims ore

OF the group a good deal of low grade
cyanide ore has been exposed. The
adjoining properties show much high
grade cyanide ore. The formations
Of the Alameda group are the same
as those on the Big Six.

out this region. The Rosseau proper
ties are located on Collar Butte about
one mile northeast of Maiden, near the
road from Maiden to the old town Of
Rustic.
There are but two claims in the
group-the Cumberland and Cumber-
land No. 2-embracing the entire south
and a greater part of the north and
west of the Butte. These claims were
located last year by Peter Rosseau,
well known among the p~rospectors
and miners Of the Judith range, he
having worked in the country around
Maiden and Gilt Edge for the past
twelve years. But Rosseau's location
is not the first mineral location On
Collar Butte, as the several dozen
holes that honeycomb the face of the
hill will bear witness. For the past
fifteen years different prospectors
have made locations in this ground
and allowed them to go by default
and nearly every prospector around
Maiden, has at some time owned an
interest in the ground.

ground and began something like a

ores a regular mill test by cyanida-
ton and this spring he erected a
wooden tank and placed other appar-
atus on the ground for that purpose.
He treated about sixty tons of I'M
crushed ore In this tank, securing
therefrom a gold brick worth s20S.
The ore treated vas fully one-ffth too

from samples Of this ore dealt largely
in traces, 30 cents, and less than
dollar results to the ton, but In a few
instances the returns would go above
$40 per ton and one assay went to the
Eighty reach of $39. Still, the owner
of the Cumberlands did not know
where he was at" and determined
upon the mill test with the results
mentioned above. The location Of the
claims permits their working by a tun-

pounds of powder was used in its ex-
