METALLIC MINEEALS. 



TITANIUM. 



EUTILE. 



Tliis mineral occurs in the form of fair-sized crystals at 



Lyndoch, CoUingrove, Tanunda Creek, Mount Crawford and 



near Encounter Bay ; also (with quartz sand) near Balhannah. 



TIN. 

 Cassiterite. 

 Although the finding of this mineral has been frequently re- 

 ported, it is doubtful whether any authentic specimens have 

 been discovered in the southern part of this province. I have 

 a specimen of stream tin in the form of fine grains, which is 

 stated to have been found in the Port Lincoln district ; but as 

 the party who is supposed to have found it there failed to ob- 

 tain a further supply from the same spot, I am compelled to 

 look u])on this discovery as very dubious. Entile in the form 

 of sand and crystals has been frequently mistaken for tin ore. 

 Cassiterite occurs in the Northern Territory at the McKinlay 

 Eiver, Mount Wells &c. 



MOLYBDENUM. 

 Molybdenite 

 Is of frequent occurrence at the Yelta Mine, and in smaller 

 quantities at the Moonta, Wallaroo, Kurilla and other mines 

 in the same district. Tate also reports it as being found in 

 gneiss near Franklin Harbour. 



BISMUTH. 

 Native Bismuth. 

 This mineral occurs at the Balhannah Mine and the Mur- 

 ninnic Mine, about 20 miles north of Franklin Harbour. 



Bismuth iNiTE 

 Occurs at the Balhannah Mine. 



BiSMUTITE 



Occurs at the Balhannah Mine, associated with native gold and 

 chalcopyrite (copper pyrites). L^lrich reports its occurrence 

 at the Stanley Mine. 



IRON. 

 Native Iron. 

 The only specimen* of Native Iron which has been found, or 

 at any rate scientifically made known, up to the present time 

 is in the form of a mass of meteoric iron obtained in the 

 Gawler Eange in November, 1875. As no particulars of this 

 meteorite have hitherto been published, the following informa- 



* Now iu the South Australian Museum.
