The LENGTH OF TIE Higgins tunnel through
which Wolverine is bringing out its ore about 1000
teet As has been said there this tunnel several
places at which it looks though there would be profit

from il Mabye there will be- later on At present this
tunnel not TO be considered unde the plan of the
easers and their engineers OF the latter George Lane
mas rendered exhaustive report the property as the
resun OF recent examinations His report has been
made public but ii is understood give very high rec

OTHER NEW Development must include the pros
pecng work OF the CopperQ Queen toward the old Cop
per kng property the most important underway with
reference to large bearing upon expansion of the
ore zone OF the immediate district That Copper Queen
made considerable explorations of Copper King ground
while back through churn drill operations, is we'll
known. Later the churn drill carried across the
gulch and has recently operated about line north of
Copper King holes upper side of and TO the
railroad track This mole is doubtless connection with
previous investigation carried on by the Queen manage
men about the old hospital site and through the incline
shaft and the tunnel in the vicinity of the old Stag dump
All of these investigations showed and will ultimate
y it is believed from what lis known of results result
the addition TO Copper Queen operating energies of
considerable new area of scing territory
WORKING ACROSS The guch there has been car
ried out drift of probably 500 feet from the Holbrook
over toward the old Copper King This drift stops about
the county9road and will be followed Immediately by
other from the 800 level The present drift only about
IS feet below the road 1t all the way in fair grade of
ore. Should the 800 drift find this ore it needless
say that there will have been opened up another very
valuable body OF course the 800 drift will be able TO con-
tnue over into Copper King ground proper hat the
latter has the point hat there is little question
raised about in these late days though there time
when it positively held that the did the

good deal of individually held ground is made very vaua

in this immediate Geighborhood very materially broad

THERE WERE Introduced into copper history some
very interesting facts by General Manager MacNaughton
of the Calumet and Heca the of his speech at
the Isle Royae Celebration Dinner Houghton last Mon
day night presented interesting figures TO the cost
OF mining the different mining districts in this country
His remarks the policy of the porphyry managers
in deferrng stripping charges ETC. OF particular in
terest ,inaSmuch this policy is given endorsement
MIR. McNAUGHTON is unquestionably the best OF
authority but summing of Southwestern ne might
very properly have differentiated trfle instead OF hav
ing included all of the Southwestern high grade country
under head OF the costs Of Bshee under
treatment phenomenaly low, but in the estimate OF
Mr. McNaughton these are ade figure with of
Old Dominion Arizona Copper Detroit Copper and Can
copper besides Others which is the face unfair
Bisbee though evident from his statement that
Mr. McNaughton does not contemplate any unfairness.
HIS ERROR is in the simple fact that he has not had
in the preparation of his such time is permS
Sibe for the entering into of all details perhaps bet
ter the time permissible be fore the subject OF his adj
dress Both ways iVabe and entirely possible
Nevertheless the Warren district may properly claim that
its production of copper at less figure than quoted by
the Michigan expert.
THE LATTERS statement carries very large
amount of information regarding copper production
generally and very much worth while of comprehensive
consideration by everybody interested in whatever in
the industry. 1t is follows:
THE ROCK of the Isle Royale mine is lower in cop
per content than the average OF that produced in this
district and the per pound Of copper produced is
somewhat higher than the average pound for the
district The average copper yield per of rock for the
the results of the Calumet and Heca conglomerate
eliminated and only the amy gdalod mines considered
the average yield would be only IS pounds while the yield
the Isle Royale for the period 1914 pounds
The cost of pound of copper for theientre dis
