The mine closed in the early 1900s due to low metal prices and the sulphide problem.  It resumed production in 1906, selling concentrates to the newly formed Zinc Corporation, but closed in 1928 after producing 1.6 million tons of ore valued at 4.7 million pounds.  The mine was reworked by North Broken Hill LTD from 1948 to 1952.                                                          BRITISH BHP MINE The British BHP Co. LTD was formed in 1887 to control Block 15 and 16 of the original BHP leases.  A smelter was built in 1891 to treat oxidised ore which was previously concentrated in a large mill.  The mill closed 1901 due to the sulphide problem.  By 1910, the company had removed most of the accessible ore and, in 1923, sold the leases to North Broken Hill LTD after producing 2.8 million tons of ore.  The latter company reworked the mine until 1958 from Thompson and Blackwood Shafts.  The area was reworked by open cutting in the 1980s.                                                             JUNCTION MINE This mine, located at the northern end of the outcropping lode, was first pegged in 1884.  The Broken Hill Junction Silver Mining Co. was formed in 1886 and three shafts were sunk.  A smelter was erected at Port Adelaide in 1890 and the company prospered until low lead prices and treatment problems forced closure in 1901. This mine reopened in 1906 using Browne Shaft as the main access.  The company struggled until 1923 when the mine was sold to the Sulphide Corporation.  It was purchased by North Broken Hill LTD in 1929, after producing ore to the value of 1.2 million pounds, and reworked from 1946 until 1962 when acquired by South Broken Hill LTD; operations continued until 1972.                                                            NORTH MINE This mine was first pegged in 1883 and the Broken Hill North Silver Mining Co. was formed in 1885.  A concentration mill was erected in 1888 to treat oxidised ores, but these were depleted by 1894.  Production of sulphide ore commenced in 1897 and the first dividend was paid in 1899. When the company became North Broken Hill LTD in 1912, its mine had become one of the largest at Broken Hill.  The neighbouring British, Junction, Junction North and Block 14 Mines were acquired between 1923 and 1942. A NEW MAIN SHAFT (No 1), begun in 1905, was used for all ore haulage until No  2 shaft commenced operation in 1933.  A new concentration mill was erected in 1939 near No. 2 shaft.  No 3 Shaft, at the northern end of the orebody, commenced in 1948 and was commissioned in 1962.  This steel and concrete lined shaft, elliptical in shape, reached below the 1600 metre level, making it the deepest in Australia.  Open – Cut operations commenced at No 1 Shaft area in 1985.  Production from the North Mine up to closure in 1993 was about 34 million tonnes of ore.                                                         CENTRAL MINE The Central Mine was pegged in 1884 as Block 9 on an irregular shaped lease not covered by the original leases of 1883.  A company was formed and operated until rich silver ore was exhausted in 1892.  The mine was acquired by the Sulphide Corporation in 1895 and operated until exhaustion of ore reserves in 1940.  The leases were transferred to South Broken Hill LTD, which reworked the mine between 1945 and 1961.  The mine produced 6 million tons of ore and paid 4 million in dividends.                                                            SOUTH MINE The Broken Hill South Silver Mining Co. LTD was formed in 1885 to work Blocks 7 and 8.  Mining commenced in 1888 and smelter was built in 1891.  The South Mine encountered the sulphide problem early in its history and, as a result, did not pay a dividend until 1897.  Broken Hill South LTD was formed in 1918 and quickly became one of the most progressive companies at Broken Hill.
