THE South Mine. owned by the Broken Hill South Limited, occupies mineral leases 7 and 8 on the Broken Hill lode. The ore reserves are 4,250,000 tons, and the ore hauled for the year ended June, 1930, was 387,000 tons, the total to date being 7,840,000.The mine, down to the 1070-ft. level, is naturally divided into two sections, the northern and southern ends. Ore extraction is practically completed in the northern end to this horizon, while the southern end is developed ready for a concentrated attack.Fig. 1 shows the state of the 8215-ft. level, after connection to the new shaft.The levels above and below to the 1070-ft. level are in a similar condition, while below the 1070-ft. level the stoping has been confined to the north end, but not completed. The south end on these levels is also partially developed.The ore at present is hauled up No. 1 shaft, which is centrally situated to the present workings. This shaft was put into use in 1909, and in 20 years has had approximately 5,000,000 tons of ore pulled through it.The company, having proved the existence of large ore-bodies in the southern end of the mine, decided to sink No. 7 shaft. This is a six-compartment frame-set shaft (see Fig. 2) equipped with two cages and two 5-ton skips, the remaining compartments being utilised for electric cables, pipes, and ladders. The surface arrangements will include a steel head frame, electric winders, and breaker station.
