- ITOGON MINING COMPANY During October Itogon treated 32,480 tons of ore from which P371,043.56 was produced, a substantial gain over the last three months. Recovery per ton was Pll.42 while extraction was 85.93%. Development advance was 4,016 feet, 2,147 feet of capital and 1,869 feet of operating. Of the capital development 323 feet' were in ore, as were 898 feet of the operating advance. Two new raises have been started in good ore on the Taka vein. On the 3 level in this section of the mine the west drift was advanced through the old drift, and good values were encountered in the old fill, which is considered encouraging. 4B stope has produced some good ore ; nothing but virgin ground has been mined in this section. The 21 · raise was driven vertically from the main counter drive until it intersected the Taka Vein. The fill gave a good average through this section and the raise was continued through the old fill to the 3 level. In the Idol section, stoping is now under way on the 100 level. On the 200 level the east drift connected with the east 312 raise and is being driven to the east. The 523 winze in the Sesame section was advanced 31 feet during October and is now about 120 feet below the 500 level. 875 level, 23 raise, was advanced 85 feet during the month; connection with the winze is expected by the first of December. The 96 vein crosscut was advanced 226 feet in October, and has been turned to intersect the N 45 W branch of the 96 vein. The N 70 E branch of this vein was intersected by the crosscut during October, and a wide mineralized zone was encountered having commercial possibilities. Drifting on this feature will be started later. nusTON Horizontal always 4 prove successful Whether installed within the Arctic Circle or on the Equator, the Ruston horizontai oil engine always gives a dependable supply of power.
