that. of any other. year since 1880, and there is good reason to 
think that even this satisfactory total does not include all the 
the gold raised, for there are no returns of the amount of gold 
which goes out of the Colony associated with metalliferous ores. 
It is known that 5,277 ounces of gold were in this way taken 
from the Proprietary Mine, Broken Hill, in 1890; but for 1891 
there are no returns of this item. 
The value of silver and silver-lead ores won in 1891 reached 
the enormous sum of £3,619,589, an amount nearly a million of 
money greater than it was for 1890. The total value of the 
mineral products in New South Wales for the past year, ending 
3lst December, 1891, was six and a half millions, and the total 
value of the minerals won in New South Wales from the founda- 
tion of the Colony to the end of 1891 reaches the enormous sum 
of ninety-three and a half millionsof money. Dividing the value 
of the gold won in New South Wales in the past year 1891 by 
the number of miners employed, it appears that the amount earned 
by each mineris £51 9s. 6d.. This is a very rough method of 
computing the earnings, because there are so many other things 
that ought to be taken into the account. 
In coal also the out-put has been greater than it ever was before, 
and in value it amounts to £1,742,795, and the prospecting for 
new seams and new coalfields has been most satisfactory ; the 
Government diamond drills have bored through an aggregate 
thickness of new coal of one hundred and thirteen feet nine and a 
_ half inches (less twenty feet bands and coal) distributed as follows: 
Waratah, ten feet ten and a half inches; Cessnock, twenty-two 
feet ten and a half inches ; Nobby’s, eighteen feet nine inches ; 
Greta, twenty-two feet one inch; Cremorne, twelve feet and a 
half inch ; Wyeé, three feet three and a half inches ; Bulli, three 
feet ten inches. In 1891 sixteen new coal mines were opened. 
Platimum.—In view of the rapidly increasing value of platinum 
caused by its use in electrical apparatus, the announcement that 
considerable quantities of this metal are in the hands of miners 
at Evans Head, where they have obtained it from beach sand,
