Some late letters from Lake Superior contain the annexed
information nregard to various mines:
The National Company have found the Minnesota vein
and it is very large and wei filled with copper The
North Western has improved very much. Masses of
pure copper $500 5000 lbs not unrequent through
great execution Our mine throughout is producing cop
per 10 an extent unequalled at any previous time
The North American Mine in the south part produces
very extensive masses pure copper ahd now BIDS il

VI the coast Of Lake Superior.
AT the Minnesota Mine No. shaft carries strong
lode only forty feet from the surface which has continued
down TO the level The tenfathOm level east OF No.
shaft has good lode also and in the twenty fath0m
level we are engaged in cutting up tho large of

level is vcry rich containing and barrel work In
the drift west of this shaft the vein is two feet thick OF
good barrel and stamp work Several places in the bottom
OF the thirty fshom level show good lode and OF
corper extending down. from which il Is fair TO judge OF
what shall find in the forty iahCm level beneath.
Near No 3 shait especially have Just como upon
rich lode which will produce masses In twenty fathOm

Is VeryrCh In the adt level hearth west end have
mass Of 40 tuns still fast in the vein, though
have already tried two three blasts behind it, and
are stoping away the ground still further to have
another trial il. Near No shaft still cutting
up the other large lof over 100 tuns heretofore
advised which viii require several weeks yet 10 complete
some of the cuts being five feet thick of pure and
solid COPPER The lode largo and rich from the
cut west of this shaft and also good in the shaft under
the level The lode in the shaft No was small at
the start but has been steadily improving in the drift and
few days since raised from il mass of 100 lbs.
On the whole may say that the mine generally has now
more copper in sight than has ever been seen before
especially at this season OF the year
"Roekland Nine situated east of and adjoining the
Minnesota workswas commenced in June last Two shafts
have been sunk 800 feet apart aud to the depth OF about

shafts as the depth Of III feet which expected to
