CLAIMING REPORT
ON THE MIAMI

-Four hundred feet east OF the shaft a
second crosscut shows ore for width
of $50 feet north and south, with both
ends continuing Ia good ore. The to-
tai area Of ore developed on this level,
determined by drawing lines from the
ends Of the various workings, shows a
total of $4,000 square feet.
Our Reserves.
Taking the ore as extending fifty
feet above the 270-foot level and as
Stunning that IL continues fifty feet be-
low the 470-foot level, there has de-
veloped about 53,000,000 cubic feet OF
ore. At twelve cubic feet TO the ton,
which experiment has shown to be
conservative, there Is actually blocked
out 4,400, 900 tons or ore. Taking but
a moderate extension Of the ore body
| laterally TO the east and south and
assuming that the ore is continuous to
| the 570-foot level, or 100 feet below
the present developed level, one is
safe in assuming 100000 tons of
probable ore, this making total OF
actual and probable ore of 6.6O0.eOO
tons.
| Surface conditions indicate that
even this by no means exhausts the
possibilities of the ground, so that
| the chances for very much extended
and enlarged work in every direction
is being vigorously pushed, so as to
block out the ore as rapidly as posi-
Bile.
THE sampling of the mine has
been carried out most Systematically
| by the management, every drift and
crosscut having been sampled In five
| foot longitudinal sections. ! have per.
sonally checked long stretches of the
various openings. in addition to which
they have been checked at separate
| time by one of my assistants, and
have also been checked by an indie
pendent engineer not connected in
Iany way with the management. From
a careful compilation of these assays,
an Of the opinion that the average
assay of the ore is not less than go
1percent) two and nine-tenths per cent.
Costs and Profits.
| 'As before stated, the ore will yielt,
forty-two pounds of copper to the ton
and l estimate that the cost of cleo
tTolytic copper sold in New York will
be (9c) nine cents per pound.
Assuming that the proposed plant
! will treat $50, 900 tons OF ore per an

annual profits at varying prices OF

Net Value Developed.
AS an indication of the present Val.
ne of the property, the profit per ton
of ore with copper at 12lsc amounts
to S147. while at 15c per pound the
profit per ton would equal S2,52. As,
Stunning that out OF 6,600,O00 tons actu,
al and probable ore developed only
s 900 900 could be recovered, and it is
expected that between 80 per cent and
los per cent of the ore developed can
be taken out. the value of the ore in
