The report dated April Is, 1918, showed. connection a Den maui

rotten timbers. After two weeks of work it was proven it would be X

the shaft from the 20O-foot level to bottom. n character OF grounno
az found to be identical as that IN the 400-foot level in main na1
It was decided that the development could be carried forward more
economically from the main shaft. Consequently work was discontinued
375foot level of the main shaft was started a few days slater. Th1s cross

crossed to the 2Oofoot point. At a point 100 feet from the crosscut an
incline raise is now being driven o. the foot wall Of vein to prospect n

raise must be driven is feet higher and a crosscut of about 80 feet oe
driven before the objective point is reached. Bad air va encountered
and timbering was necessary the entire length of raise.
This drift the 375-foot level when EXTENDED to the Vcinlty OF TN
Iockhart shaft will be SO feet deeper than the present bottom Of tn
shaft on account of the difference in elevation in collars OF shars.
On April 1, the drift N the 16O-foot level measured 926 feet. This
drift was extended easterly for n feet and a crosscut driven northerN
toward the Lockhart shaft a distance of 43 feet. The face or this cross
cut must be advanced 40 feet to reach the Lockhart shaft.
Numerous drifts crosscuts and raises have been driven from this
160foot level and from the slopes above. Incline raises o n vein connect
these slopes with the surface. All ore produced during the nine months
came from the slopes, drifts and raises above the 236 and 16O-foot levels.
Ore of erratc values is % being produced from a drift out of a rahe
about 100 feet from the surface.
The plans of development ire, to continue driving easteriy on tne
375foot level to intersect the downward extension of the ore shoots *
posed in the slopes on the 236-foot level. 1t is believed the values VIII
be less erratic n o. concentrated o. the deeper level Raising M
drifting above the 160foot level will be continued with a icy OF extend
ing the present ore exposures.
During the nine months ending Dec. 81, 1918. 24 dry tons of ore
1855 per ton. The total deductions for freight. treatment, sampHng,
smeler losses, etc., amounted to s26S5.49, leaving the net returns 10
your Company $3293.53, O. a return of So per cent of the total gross
value of the ore produced.
The testing of the mill grade ore to determine the proper treatment
has been carried IN al advised in former report, but, as yet, not in suffi-
Gent quantities to determine the exact percentage saved n the cost de-
tans. The values in the ore continue to be very cratic and it is neces-
sary to platform sample all ore produced. Ore samplng lest than $500
per ton is placed on the mill grade dump.
