Tin-field comprises large area between Murray and Mitta-mitta rivers. Bed rock is 

 granite of various kinds, mostly coarse with black and white mica in large plates. 

 Deposit varies from few inches to 2 or 3 feet thick. Wash dirt made up of boulders 

 and angular fragments of granite and quartz. Ore is disseminated all through wash, 

 and also in layers, but more plentiful on or near bed rock. No lodes of workable size 

 found. Lists of principal claims given. 



974. . Report on the gold discovery at Tarcoola, the Enterprise Mine, 



the Earea Dam tin find and the Mount Gunson copper mine. 



Rec. Mines, South Australia, 1900, Adelaide, p. 6. 



The tin discovery is situated !*/& miles south of Earea Dam, on a mud lake where 

 the surface sand and loam have been eroded, and expose granite, diorite and other 

 hornblendic rocks containing quartz. A dishful of the alluvial soil over the tin vein 

 outcrop yielded 1 pound, 10 ounces of tin; on being smelted, it gave 1 pound tin or 

 90 per cent. Prospectors have sunk in the quartz veins, but would probably meet 

 with more success in prospecting for alluvial tin.
