regards the more costly and precious metals. For instance, Lead has been 
worked in South Australia at the Wheal Gawler, Wheal Watkins, and 
Glen Osmond mines, &c.; and is known to exist in Tasmania, New South 
Wales, and Victoria. Copper has also been found in Tasmania and Victoria ; 
it has been successfully worked in New South Wales; and perhaps no 
copper mine in the world ever yielded returns so rich upon an outlay of 
capital so small as the Burra Burra mine of South Australia—the shares 
in which, originally £5 paid up, rose within two or three years nearly to 
the value of £200 each! From the opening in 1845 to the end of 1850 
(when 1000 men were employed), this mine yielded 56,428 tons of ore, 
averaging 40 per cent. of copper. 
Gold has been found in Victoria, New South Wales, Adelaide, and 
Tasmania. In Tasmania, although found at several points, hitherto in 
small quantities: In Adelaide also in small quantities. In New South 
Wales, in the Bathurst and the adjoining districts, to such an extent that, 
from the discovery in May 1851 to the end of 1852, the quantity of gold-dust 
exported to England amounted to 1,256,295 ounces, of the value, at 67s. per 
ounce, of £4,840,000; while from Victoria the export of gold to England, 
from the discovery in October 1851 to the end of 1852, amounted to 
the value 2,377,968 ounces, of the value of £9,160,000, making a grand 
total within twenty-one months of £14,000,000 sterling ! 
In the report of W. Westgarth, Esq., M.L.C., to the Chamber of Com- 
merce in February 1853, it is stated that the quantity of gold ascertained 
to have been produced in the province of Victoria in 1851 was 145,146 ozs., 
and in 1852, 3,783,780 ozs., making a total of 3,928,926 ozs., which at 
£3 17s. per oz. was worth £15,026,365 sterling. 
The total quantity of gold produced in California in five years, from 1848 
to 1852, was of the value of £40,000,000. The quantity produced in 
Australia within one year and a half was £16,000,000! 
The estimated value of the gold brought into the markets of the world in 
1852 from all sources, California and Australia excepted, was in round 
numbers £9,400,000; from California £12,500,000; while from Australia in 
the same year it was £14,400,000. 
The largest amount produced in one year in Russia was, in 1848, 
£4,100,000. 
In 1843 the largest lump of gold at that time known in the world was 
found in the Ural Mountains, now deposited in the Museum of the Im- 
perial School of Mines, St. Petersburgh, weighing 78 tbs. This, however, 
has been completely thrown into the shade by recent discoveries in Aus- 
tralia. One of these large masses, found at Ballarat in Victoria, weighed 
132tbs. It has since been exhibited in London as one of the wonders 
of the world,
