operated solely by the Bells Bros.
Three feet and half are daily being

pushed rapidly and the 6OO-foot tunnel
is now on the second contact and in
cyanide ore with traces of the tellur.
ides. In this mine the porphyry hang
ing wall with we'll defined lime foot
is very evident, the contact being cas-
lily traced. Forty feet of solid cyan
ide ore was encountered on the first
contact. The ground breaks we'll, and
rapid progress will be made. one val
liable asset on this ground is fully $50
inches of water which is easily con.
trolled for mill purposes.
At the Maginnis mine several men
are working and considerable ore is
being shipped while the Cumberland
group employs small force. The War
Eagle is being operated by George T.
Carr, of Chicago, for the Maitland in
terests, under a bond and lease from
Stewart T. Burr. Many hundreds of
tons of lead carbonates have been
shipped from this mine and prepare
lions are being made to thoroughly
exploit the ground.
There are number of first-class
prospects in this district which are
well worth developing and in truth
the entire district is in need of thor
ough development at the hands of cap
ital. There is every indication that
the primary formation of the ores of
this particular locality was telluride
which through decomposition and OK.
idizatiOn on the surface has become
free milling ore though still retain
ing it's original formation in the deep
err levels. These ores are highly 81.
liceous and an ideal fluxing. Consid-
cradle of these surface ores are sus-
! ceptible to cyanide though the best re-
suits would be obtained by a compo-
site treatment with the stamps and
tanks.
The history of the ores of the Ma
ginnis and the Spotted Horse are prac-
tically the same, the ores being found
in irregular bodies and in rich vugs
near the surface while in the deeper
levels the richer ores are found in
place and in distinct leads. Both these
properties have been but gophered out
and no depth has yet been attained.
The richness of the more valuable ore
vugs in both of these properties is
somewhat phenomenal and $4,000 TO
the ton has been secured from small
finds of the rich shipping ore which
is of the telluride variety. Fluorite
is encountered throughout the district
| and small finds of sylvanite have been
made. The formation is without ex-
| ception very much broken up near the
surface and the porphyry intrusions
are very evident in broken masses
of carboniferous lime. The trend of
the main leads is east and west but ex-
ceptional finds of ore have been made
in the most unsupported localities
showing the district to be highly min.
eraliZed throughout
Of course the original tellurim ore
is refractory and this is precisely what
has held the district back owing to the
fact that it takes a considerable out
lay to thoroughly develop a mine OF
this nature though there is no doubt
but that the returns would be i'm
mense. Every section of the hills in
the vicinity of Maiden is highly min.
eralized and without question the dis
trict is one which will rank with the
best in the near future.
