year.
Upon comparison with the report for the year 1915,
the following facts are noted for the year 1917:
The net realization shows a decrease of $256.O996O
The tonnage produced shows a decrease of $3.50
The footage of development work was 1886 less.
The grade of ore shows an increase of &c per ton.
The total cost, including marketing flotation concen-
trate, cost Of failing treatment, Was oe a more b per u y n in
crease of 47c per ton.
The cost of failing treatment per ton of failing, ex-
Guiding all overhead expense, was 44c per ton.
The percentage of profit from 1914 ore in 1917 is
s.4s% as compared with i7.76% profit from 1852 ore in
in 1919 e a'''' ''S' . ''i"s - 9'''
No fatal accident has occurred within the year, which
establishes a record of thirty-six consecutive months with
out a fatality.
Within the year 14,7o dry tons Of ore of average
value of SAB and gross value of $Si7 533 were pro
lessees. From this sum lessees paid expenses OF labor and
powder. The records show approximately 5000 shifts OF
Of production which indicates that taken as a whole the
lessees have made no profit. Some individual leases nave
been profitable, but to no great extent. This result has been
most disappointing, since it has been hoped lessees would
open up new ore bodies. There are now Az sets OF lessees
at work employing 80 men, and as rapidly as the Company
withdraws from a section OF a mine 1t is opened 10 iessees'
and this policy will be continued.
It's not possible to offer more liberal terms to lessees,
enough to pay the expenses of handling lease ore. Costs
have naturally increased with the reduction IN tonnage
ing would be stimulated even if more liberal terms were
made, since many of the blocks already opened have been
leased several times.

March and has been in continuous operation since that

least csc. 900 tons will be milled before operations cease.
The plant for rehandling failing was placed IN service
in Id June, and it was Immediately demonstrated that the
Lidgerwood cable way with clam shell bucket did not
have more than one-half the rated capacity, OF 1OOo tons
in 16 hours. 1t has been impossible to date to average
500 tons in "a hours. Experts from the manufacturers
plant have spent months on the ground, and beyond hav-
ing been of assistance in educating operators they have
found no solution for the difficulty save the purchase OF
a larger bucket and changing the method OF handling the
failing at the discharge of the cable way.
1t is impossible to keep the cable way in operation for
"a hours since the wear and tear on the cables, carriers
and bucket cause daily s~hut-downs for repairs, A larger
to operate with the present bucket for a sufficient length
of time to determine the type of bucket best suited to the
work.
The changes necessary to improve and cheaper the
present method of handling the failing discharged from
the bucket at the mill are now under way ana shoald IN,
as the mine produces 1900 tons per month of ore amen
able to the cyanide process the present bucket should be
not exceed $4,000 tons per month. It is hoped to have
the failing plant up to a capacity of 800 tons per day In the
early spring.
Since June 81 ,SS5 tons of failing have been treated,
having an average value of 1927. Numerous tests in the
laboratory made on the failing which has been recovered
indicate a recovery which leaves 4Oc in the failing regard
less of the grade. Since the failing and mill ore are treat
ed together in the same tanks and filters it is impossible
to determine the exact recovery from failing in the mill,
and in arriving at the profit from failing 6O% has been
taken as the extraction. The cost for retreatment for the
six months period has been 44c per ton of failing treated.
The fact that the failing treated to date has averaged
only 1.27 need cause no alarm, since the failing made
during 1914 and 1915 has been deposited on top OF the
high grade failing deposited during 1909, 1910, 1914 and
1912. and in recovering the failing from the pond this low
grade material must come in first; one cut has been put
