Capital develop ment accounted for 1,476 feet, of which 192 feet were in ore, and of the 506 feet in operating, 259 feet were in ore. The 200 level Spokane north drift in the San Mauricio mine was advanced 102 feet in ore averaging P41.30 per ton over a width of 32 inches. The 300 level south drift on the 2230 vein was advanced 90 feet in ore averaging P81.20 over a width of 28 inches. The 750 level shaft crosscut was ad vanced 163 feet in hard granite gneiss. Capital development on the vein in the Santa Ana mine was limited due to the hoisting equipment being kept busy handling ore. A larger hoist and a new steel headframe are now being installed at the Santa Ana mine. The Spokane shaft was sunk a total of 24 feet. Excavation for the 8,000-ton oil tank was completed. Operations on the property were normal during the period under review. The Marsman Magazine for September, 1939
