The report states that drilling for de-
veopment alone was entirely discon :
developed approximately $500. 900 tons OF
ore in addition to that shown in the last
annual report. The total developed and
partially developed ore on April ], 1911.
was Il, ,o35. 900 tons OF this quantity ST.
S3l 900 tons are cassed as developed and
the remainder as partially developed; The
average copper content of the developed
and partially developed ore is the same as
that given In the last report, namely.
2.l7 per cent. The area developed ana
partially developed ore is lS4 acres. as
compared with 1T6 acres shown by the
last report.
General Manager D. C. Jackling SAYS:
Generally speaking. the conditions at

company, as well as the progress made
In the development OF the mines and con-
struction OF improvements during the last
six months have been distinctly satlsfac-

Total Ore Tonnage.
Drilling for development alone was dis

after developing about 100000 tons OF
ore in addition 10 the amount shown in
the annual report, According TO April
report the totally and partially developed
ore amounted 10 I7.535.ooo tons, OF which
6s.s3l 900 tons was developed and the rest
partially developed. The developed class
includes only those areas which have
been systematically drilled in 200 feet
squares. and the partially developed class
is represented by areas that have not
been completely drilled In 2o0-foot
squares. but where In some cases the
drill holes used In tonnage calculations
are as much as 400 feet apart The ore
tonnaees do not include all allowances
beyond the lines OF holes drilled as de-
scribed and forming the boundaries of the
areas to he given. so that the tonnages
given do not represent much ore as
really exists Some outlying holes are
also too far away from the regular drilled
sections 10 connect up and include
with them. With reasonable allowance
for these factors the amount Of ore
proved TO exist through drilling and
checked by underground development will
exceed 6o.oo0.n n0o tons. The average cop
per content remains the same as for last
year. when IL was 2.iI per cent.
Both the area and tonnage figures
given represent the combined develop
nnents on original Ray Consolidated ter
Titorv and that formerly owned by the
ter's property having been conveyed TO
the Ray. On April the total length OF
underground workings was ss.65l feet,
an increase of about 100 per cent over
the period covered since the last annual
report

been started September Is.
The first main level connecting the No.

been completed for length OF nearly

equipment will in the meantime handle
the ores mined from the western portion
of the ore body. Since the last annual
report $4,000 tons of ore have been pro-
duced almost entirely from development
workings. which includes the preparation
OF A few slopes for actual mining. No
extensive Stopping was done up 10 April l.
The railroad from Kelvin to the mines
has been extended about one mile from
the No. ! shaft to beyond the No 9 shaft
ed near the No. 2 shaft. The road is
handling a good volume of business and
its earnings. aside from the ore bust
profit above operating and fixed ex-
penses The road has 100 sixty-ton steel
ore cars; one locomotive and other gem
TWO other locomotives have been or
dered, The general office has been
moved from Kelvin to Hayden and the
offices at Kelvin closed.
The progress made at the mine dur
ing the past six months is regarded as
very satisfactory. The character OF the
ground as the mine has been opened up
has been found to exceed expectations

previously decided upon. The develop
ment OF the main water supply al Hay
den has removed all questions of hin
drance or OF heavy expense in times OF
high water In taking water from the
river direct. With the mines and plants
in full operation II is estimated that the
cost OF producing copper at Hayden will
considerably shade the previous esti-
mate OF cents pound,
