Of copper the recorded quantity produced in 1860 was only one ton, valued at L50; but two years later the value reached L10,332 through the discovery of the Peak Downs mines. The two following years showed an almost entire cessation of export, although some L90,000 worth had been won. In 1865 the value of copper produced was L58,440. Thence there was fluctuating progression until 1871, when the value rose to L174,300, with a further rise to L196,000 in 1872. Declension followed until in 1882 the production had dropped to L14,982, the quarter-century closing in 1884 with a total of L30,872 worth. The explanation is that during the period there was practically only one copper mine at work in Queensland, and that in 1871 the policy was commenced of smelting all the richer ores and paying the highest possible dividends. In one year an amount of about L300,000, equal to the total capital of the company, was distributed, and shortly afterwards the mine was closed for want of remunerative ore. Had money been freely spent in exploration, as at the Mount Morgan Gold Mine, and only moderate dividends paid to the shareholders, it is believed that the life of the Peak Downs Copper Mine would have been indefinitely prolonged. During sixteen years of the second quarter-century copper mining languished, the highest production in any one year being valued at L20,340, while in 1891 the lowest descended to L865. In 1901, however, through the opening of the Chillagoe mine, the production rose to L194,227 worth; by 1906 it had continuously ascended to L916,546, and in 1907 to L1,028,179. In 1908 there was a phenomenal decline in production value, owing to the low price obtainable for copper, the total being stated at L882,901. The first production of tin is recorded in 1872, when the yield was valued at L109,816, through the discovery of stream tin in the Severn River district of Queensland. The record year for tin production of the half-century was in 1873, when the value raised was L606,184. Thence there was a fluctuating decline in output till 1884, which closed with L130,460 worth for the year. In the second quarter-century there was a fluctuating diminution of production, till in 1898 it was only worth L36,502. After that date there was a continuous improvement, the figures reached in 1907 being L496,766. The tin won in 1908 was declared to be of the value of only L342,191, the reduction arising chiefly from lowered market prices. The coal raised in Queensland in 1860 was only 12,327 tons; in 1884 120,727 tons were raised; and in 1908 the production was 696,332 tons, valued at L244,922. IMPORTS AND EXPORTS. The imports into Queensland in 1860 were of the declared value of L742,023; at the close of the first quarter-century they exceeded 61/4 millions a year; in 1900 they exceeded 7 millions; in 1908 they totalled nearly 91/2 millions.
