THE August 1938 SMAN Vol. III No. 2 MAGAZINE July Operating Results Excellent July production at the Marsman gold 'J)roduce:rs resulted in an output of Pl,223,384.90 from 56,826 tons of ore milled and 352,055 cubic ya1~ds of gravel dredged. The total was but slightly under the record set in April. A new monthly all-time record was set again by the United Paracale Mining Company, with an output of 'P226,539.14 from 9,572 tons of ore treated. Operations went ahead normally with excellent progress being recorded in general plant efficiency and development work. ITOGON MINING COMP ANY Itogon treated 31,042 tons of ore during July, from which P354,301.62 in gold and silver were recovered. Recovery per ton was Pll.41, and extraction was 87 % . Development work amounted to 3,985 feet, of which 2,626 feet were operating and 1,359 capital advance. Of the capital footage, 105 feet were in ore, as were 706 feet of the operating development. The 875 level Drain Tunnel, which is now being driven as a counterdrive along the Sesame vein, was advanced 218 feet. The cross section of this heading is large enough for the· installation of double track. The 500 level 96 vein crosscut was advanced 213 feet during July, and -should reach its objective within 3 months. This heading is also of sufficiently large cross section to permit the installation of double track. The 523 Sesame winze was sunk 22 feet during the month. This is actually an interior vertical shaft which is being sunk from the 500 level to the 875 elevation. It will be a standard 3-compartment shaft; a double-drum electrically operated hoist has been ordered for service in this shaft. In addition to the 22 feet of actual sinking, the hoist station, the ore pocket, and the raise to the sheaves have been completed. Several stopes in both the Taka and Sesame vein systems were finished during the month, and new stope preparations were started. Tonnage milled during the month was reduced by a broken main shaft in No. -1 50-foot tray thickener which was conse-quently out of action for 4 days. However, prompt service by the Manila office purchasing department and good work by the company's mechanical department kept the breakdown period to an absolute minimum. (Please turn t<> next page)
