Chalcopyrites. 



Copper pyrites. Chem. Comp. : Copper-iron sulphide Cu 2 S, 

 Ee 3 S 3 . Copper, 34-6; iron, 30-5; sulphur 34-9 = 100. Tetra- 

 gonal system ; hemihedral forms. A very abundant ore. 



Usually occurs massive ; occasionally crystals are met with, but 

 they are generally but imperfectly developed. Colour, usually brass 

 yellow. Blister ore is more of a bronze colour, and occurs in 

 mammillated and botryoidal forms. The tarnished variety of copper 

 pyrites, known as peacock ore from the splendid colours which it 

 acquires, is very common. 



It occurs in nearly all the metalliferous districts in the Colony : 

 at Cobar, Bingera, Elsmore, Clarence, Wiseman's Creek ; Welling- 

 ton and Bathurst districts, with zinc blende, steatite, quartz, 

 and asbestos ; Wallabadah, Carcoar, Cargo, Ophir, Peelwood, 

 Tuena, Bungonia ; at Currowang, on the Shoalhaven ; Adelong, 

 with gold ; at Lob's Hole on the Tumut ; Kiandra. 



Bell-metal Ore — Cobar. 



DOMEYKITE. 



Arsenical Copper Sulphide. Chem. Comp. : Copper arsenide, 

 Cu 3 As. Copper, 71-7; arsenic, 38-3 = 100. 



Amorphous. Occurs in the Bathurst District with yellow sulphide 

 of copper. 



Antimonial Copper Ore. 

 Said to occur at Eden, Twofold Bay. 



Dioptase, olivenite, liebethenite, bournonite, and other beautiful 

 copper minerals have apparently yet to be found. 



Iron. 



Native Iron. 



Out of a large number of specimens of so called native iron 

 which have come before me from time to time, not one was entitled 

 to be' so called ; they had all without exception been derived from 

 iron and steel tools. 



Native iron, apart from that derived from meteorites, however, 

 probably does occur in the Colony, and it is most likely to be 

 found in or near to igneous rocks, e.g., melted globules of native 

 iron have been met with at Ballaarat in Yictoria in connection with 

 basalt.
