Tlie hardness of tlie Balhannali specimen is 3"5. Its specific 

 gravity is 3' 5, while that of the Thurnburg specimen is given 

 at 3"4. This species is also reported by Tate as occurring at 

 Nuccaleena. 



Pyrite {Iron pyrites) . 

 This species is to be found in most of the lodes of the 

 Yorke Peninsula mining district. Finely crystallised speci- 

 mens exhibiting the form of the pentagonal dodecahedron have 

 been obtained from both the Wallaroo and Paramatta Mines. 

 This form is reported by Burr as occurring at the Montacute 

 Mine and the district in its neighbourhood, and also at E-apid 

 and Encounter Bays. Other localities for this mineral are 

 Talisker Mine and Bundaleer, and it is very general in the 

 various ranges in limestone, quartz, hornstone, slate, and as- 

 sociated with other metalliferous minerals (Burr). A stalac- 

 titic form occurs at the Wallaroo Mine. 



Arsexoprtite {MispicJceT) 

 Occurs at the Glen Bar Mine, near Strathalbyn, at the Talisker 

 Mine, and between Victor Harbour and Encounter Bay. 



YlVIAIflTE. 



The massive form of this species occurs at Angaston, and 

 Burr states that the earthy form occurs near Mount Euf us and 

 near Strathalbyn. 



MANGANESE. 

 PTROLrsiTE. 



This species occurs near the Wallaroo Mines both massive 

 and stalactitic ; also at Wonna Pandappa Dam and at Wauka- 

 ringa (Tate) — the specimen from the latter place being an 

 impure variety. 



MANaAlSriTE. 



This species is mined for shipment to Europe in the neigh- 

 borhood of Gordon, between Quorn and Hawker. 



Oxides of Manganese of varying composition occur in the 

 Port Lincoln district, at Wonna Pandappa Dam and at various 

 localities in the Ear North. Burr reports manganese ores at 

 Rapid Bay, Myponga, Noarlunga, River Light, Barossa Range 

 and Mount Bryan. 



ZINC. 



Spahlertte {Zinc blende). 



This mineral occurs at the AYallaroo Mine, and on the west 



coast of Yorke Peninsula, between Point Pearce and Comey 



Point. Tate reports it at North Rhine, and L, Seeger at the 



Wheal Ellen Mine.
