10 THE MARSMAN MAGAZINE [MARCH, 1937 Suyoc Consolidated Mining Company L. M. ROBINSON General Superintendent The Suyoc plant treated 6,740 tons of ore during February with a recovered value of Pl3.24 per ton, and a gross production of P87 ,842. 79. Percentage of extraction for the month was 82.34 % . Test work carried out in the mill laboratory resulted in the starting of grinding in cyanide solution and an increase in extraction. It is expected that if no complications arise, it will be possible to treat all of the mill concentrates in the S uyoc mill and thereby a void shipping them to the smelters. The higher extraction will proportionately increase the profit per ton. Development Total development work during tl~e month amounted to 1,033 feet, of which 526 was in capital development and 507 in operating development. Of the capital development, 129 feet, or 24.5 % were in ore, while 103 feet, or 20.3 % of the operating development were in ore. The timber in the main shaft has peen nea:r'ily all 1 relieved between the 1900 and 2000 levels, thereby permitting the passage of cages to the 2000 level. Excavation for the pump station on the 2000 level was expected to start about the middle of March. General Foundations for the No. 3 Allen Diesel electric unit were completed.
