Development is particularly important where a limited number of ore holes
remain to be investigated. The efforts of the small crew must be divided
wisely between mining and development in order to maintain a steady production.
Beside the two partners, three men are employed at the Sphinx and St. Patrick
mines. This five-man crew consists of one hoistman, two muckers, and two
drillers, but each man may be called upon to do any job. Drillers are paid
$2.00 per hour and muckers $1.75 per hour. Neilson attempts to keep one
driller in development headings at all times. Tons produced per man-shift
for the whole crew averaged 1.8 during the 15-month cost period. The cost
period is before Klingingsmith became Neilson's partner.
Equipment used at the Sphinx and St. Patrick mines comprises the follow-
Number Equipment item
1 Compressor, 210-c.f.m., portable, 2-stage, Sullivan; diesel.
1 Compressor, 165-c.f.m., stationary, single-stage, Gardner-
Denver XH; gas-engine and belt drive.
1 Hoist, 1-drum, utility surface, 1,500-lb. pull, 125 f.p.m.,
Sullivan PR-111; Wisconsin 4-cylinder, gasoline motor.
