1254. . Tin in Western Australia. 



Min. Ind. for 1001, Vol. 10, 1902, New York and London, p. 641. 



Total quantity of black tin mined during 1901 amounted to 734 tons, valued at

1256. . Tin in West Australia. 



Eng. Mg. Journ., Vol. 80, 1905, New York, p. 1071. 



Tin ore has been mined for several years on the Greenbushes and Pilbarra mining 

 fields, West Australia. Output of these fields is about 20O tons per annum. Mentions 

 recent discoveries of tin in the Wodgina district, and thinks it possible that within 

 the next few years West Australia will become an important tin producer. 



Wodgina district described.

" Quartz, porph\Ty dikes, also occvir bearing tinstone with tourmaline and titanite; 

 and the weathering of these dikes has given rise to the Greenbushes stream tin 

 workings."

Author states that cassiterite occurs: 

 I. Sparsely in granite. 



11. In greisen cutting amphibolite. Wolfram bearing minerals are rare and there 

 are apparcntl}' no lithia micas. 



Ill, IV. In alluvial and disintegrated deposits along with muscovite, tourmaline, 

 quartz, garnet, wolframite, tantalum and colimibium minerals. 



Tliinks veins occupy cooling cracks in granite, and that the cassiterite is of pneu- 

 matolytic origin though some water is present.

" In 1888, Mr. Stinton found some stream tin near Bridgetown on the Blackwood 

 River, which led to rich deposits, extending over about 100 square miles. The tin 

 fields are likely to produce great wealth, if properly worked."

 15-20, geologic map 1. 



Description of claims and geology of Dumpling Gully, Cowan Brook, Bunbury 

 Gully, and adjoining land. The country rock is granite, sometimes gneis.=oid and 

 containing much tourmaline, largely covered, up to 20 feet thick, with a residual 

 conglomerate. Cassiterite occurs in both alluvial and residual deposits.

 Introduction treating of tin deposits in general. 



Exports of tin ore from Greenbushes and Pilbarra, given. Production of tin through- 

 out Western Australia also given.
