The Castle Salt Co-operative Company, Limited, and the Colonial Salt Refining 
Company both give employnnent to a large number of men. 
The former company in its latest return shows that 189 men are employed in 
scraping salt and at the extensive refinery works which have been erected at Edith- 
burgh. The area held by this company is 1,742 acres, situated on Yorke’s Peninsula 
within a few miles of the port of shipment. 
The latter company hold some 500 acres situated on the above-named peninsula 
and Kangaroo Island, and employ eighty men. 
A number of farmers in the districts engage in the industry and find profitable 
employment. 
TIN. 
For some considerable time prospecting for tin has been engaged in at Earea Dam, 
and, judging from the result of parcels sent to the smelting works at Tasmania, the 
industry appears to have a favorable outlook. 
PHOSPHATES. 
A discovery of mineral phosphates has been made at Port Clinton, and great 
interest is now being taken in prospecting in that locality, resulting in the issue of 
a large number of licences to search under the Mining Act Amendment Act of 1900, 
which allows a prospecting area up to five square miles. About eighteen months 
ago the Government ofiered a bonus of £500 for the discovery of marketable deposits 
of mineral phosphates. 
The Government Geologist early in this year visited the Far Northern country in 
search of phosphates, and found specimens along the Diamentina. 
The examination of Lake Eyre and other parts in that locality was prevented by 
an unusually wet season. 
IRON DEPOSITS. 
Throughout the State there are a large number of extensive iron deposits, many of 
them in close proximity to the railway line and seaport towns. Large quantities are 
used as flux for smelting purposes, and in most localities the deposits carry a small 
percentage of gold, which considerably enhances the value. 
The principal deposits are located as follows ; — Oodla Wirra, Crystal Brook, 
Blumberg, Normanville, Eurelia, Gum Creek, Mount Jagged, Beltana, Peralilla, 
Gladstone, and Iron Monarch, the last mentioned being an enormous deposit of very 
high percentage, and is leased by the Broken Hill Proprietary Company, who have 
almost completed the construction of a railway from False Bay' (fortj'-flve miles in 
length) and an expensive jetty for the purpose of supplying the Port Pirie smelters 
with the required flux.
