Calumet, Mich, Sept. 29-one Of the. most re-
markable Textures Of the present situation in
the Lake Superior copper district is the great
amount Of exploratory and development work
that is IN progress. On all portions of the cop
per range diamond drills and exploratory open
tngs are in service.
AS illustrating the advantage possessed by the
older companies, the Calumet & Hecla will serve
as an example. 1t is developing two new mines
on the main portion Of its property. These are
! on the Osceola and sKearsarge amygdaloid lodes,
lying east and paralleling the main mine on the
Calumet xconglomerate bed. While Che openings
on the Osceola lode were created-a few years
ago and opera lions were suspended for some time
the present development work is increasing the
size OF the mine. Not only is the value of the
property being proven, but the workings are con-
| tributtng to the production Of the company, the
cost of the new work being probably more than
paid for by Its outputs.
| Another new mine is being opened by the Calu.
met q Hecla company on. the Kearsarge, and
these openings also pay largely for their cost
by their current production.

Few Of the smaller producers in the Lake su

the advance IN the price Of copper than the
! Mass Consolidated Of 3Ontonagon county. Roch
shipments have been Increased to. 525 tons daily
and current production is at the rate Of 315o oot
pounds of refined copper annually. It is con
servatively estimated that the company ia earn
Ing $4,000 net year on this metal market
AS soon as the equipment of the new shaft
is completed and the railroad spur to that pon
is ready, there will be greater increase In Mass
production.
