Abstract: Selco Mining Corporation's South Bay Mine was discovered by Questor Surveys on May 10, 1968 with production commencing }larch 3 1971. The zinc-copper silver orebodieCut and fill stoping at Selco's South Bay Mines average 200-300 feet in length and 20-30 feet in width, varying degrees to the south, and occur along a zone of chlorite alteration at the porphory volcanic contact. As of the end of August 1980 a total of 1,593,340 tons had been milled. Present ore reserves will provide mill feed until June 1981. The mine is serviced by a 2100 foot, 4 compartment _shaft consisting of a service-manway compartment, two skipping compartments one of which is equipped with a skip over cage combination,and a sinking compartment. Hoisting is carried out with 250 HP Ingersoll Rand PE-1 60" x 48" double drum hoist at a rope speed of 960 fpm. Further information as to equipment specifications is included in Table A in the appendix. The mining operation is completely trackless and a variety of mining methods includin6 longhole, shrinkage, cut and fill using mechanically placed waste rock,and hydraulic cut and fill have be􀁰􀁱 employed. 􀁳mp at -20% provides L.H.D. access as far as the 900 level. Below this level all equipment is captive and is serviced by shops at each level. Ventilation is supplied at 100,000 cfm at 6" static pressure via the ramp from a 60" Joy Axivane fan situated adjacent the portal. Booster fans at the 900 level supply 75000 cfm to the lower mining levels through a series of ventilation raises.
