The majority of the output comes from the mixed lead-zinc ores of Broken Hill; hence a statement of tonnage mined has little significance. Total exports from the Commonwealth of Australia, during 1912, are officially reported as follows: Argentiferous lead ore, 326,116 cwt.-- 214,304; pig lead, 1,438,681 cwt.-- 1,262,034; lead contents of matte, 502,264 cwt.-- 355,921; lead contents of concentrated silver-lead ore, 2,069,151 cwt.-- 1,074,153; manufactures of lead, 17,916 cwt.-- 18,812. New South Wales.--Ore hoisted in the Broken Hill district in 1912 included 28,057 long tons of oxidized, and 1,611,602 tons of sulphide ore; total 1,639,659 tons as compared with 1,484,397 tons in 1911.

This district is still retarded by lack of transport; a proposed railway has been surveyed to a point 8 miles from the camp. Only the richest silver-bearing ores are now handled.
