GOVERNMENT SMELTING WORKS. 
These works, situated at Port Augusta, are available for the treatment of copper 
ores on the following terms, viz. : — 
PURCHASE OF COPPER ORES. 
The copper contents of the ore shall be determined by the wet assay of copper of 
samples to be taken at the smelting works, less the following deductions : — 
Ores less than 10 per cent, copper, deduct IJ units : 
Ores from 10 per cent, to 20 per cent, copper, deduct 2 units : 
Ores over 20 per cent, copper, deduct 2^ units. 
Full payment will be made at the Crown Lands Office, Adelaide, for ore pur- 
chased immediately on agreement of assays. 
The price of copper shall be the latest quotation for copper in the telegrams of the 
South Australian Register or Adelaide Advertiser at the time the assay of the samples 
is agreed. 
A returning charge, varying according to the nature of the ore, but averaging 
about 37s. 6d. per ton, shall be made. 
The Government Smelting Works will take samples from each parcel of ore in 
triplicate — one for the Government, one for the seller, and one for reference in case 
of dispute. 
The selection of a referee assayer shall be by mutual agreement between seller and 
Government Smelting Works. When the referee assay is made, the middle assay of 
the three shall be taken as the assay of the ore. The cost of the referee assay shall 
be borne by the party whoso assay differs most widely from the referee’s assay. 
If the owner does not make use of his sample, the assay made by Government shall 
be the assay value of the ore, and the date of the assay being made shall be con- 
sidered the date of agreement of the assay between the seller and the Government 
Smelting Works. 
At the time of the agreement of assay the full copper contents of the ore will be 
paid for, less the above deductions and returning charge, &c. 
No allowance will be made for gold or silver contents in any ore. 
The product of the furnace will be “copper-matte,” which will be shipped else- 
where for refining. 
The ore is to be consigned and letters addressed to — 
The Manager, 
Government Smelting Works, 
Port Augusta.
