CoBALTiTE (Cohalt Glanz) . 

 L. Seeger reports having found this species at the Glen Bar 

 Mine associated with mispickel. 



COPPEK. 

 Natiye Coppeh. 

 This mineral species is represented in a great variety of 

 forms in the upper parts of the lodes of the AYallaroo and 

 Moouta mining districts of Yorke Peninsula. Some speci- 

 mens exhibit well-defined, though distorted crystals; while 

 some very fine examples of the arborescent form have also been 

 produced. In more or less rounded masses it may be said to be 

 common to the lodes of the district. At the Sliding Eock 

 Mine it occurs disseminated in various sized grains. It is also 

 found at Angaston, and to greater or less extent in several of 

 the other copper-bearing lodes of the colony. 



CUPHITE. 



This mineral is of very general occurrence in the upper por- 

 tions of the copper lodes of this colony, most frequently in the 

 massive form, but finely crystallised specimens are also to be 

 noted. Of these latter, the Moonta Mine has produced some 

 very good examples in which the planes of the octahedron are 

 most fully developed; while the Spring Creek Mine was at one 

 time celebrated for crystals exhibiting the planes of the cube in 

 a very marked degree. The crystals from the Moonta Mine 

 are characterised by an unusually strong metallic lustre. 

 Cuprite is also found in isolated octahedral crystals at the 

 Moonta and Burra Burra Mines ; while hopper-shaped octahe- 

 dral crystals have been met with at the Kapuuda Mine. 



Crystals have been occasionally obtained from the Burra 

 Burra Mine which were more or less converted into malachite, 

 and in a locality near the Ehondda Mine, north of Port 

 Augusta, they have been found converted into atacamite. 



Vao\ Clialcotrichite. — I have met M'ith this variety of cuprite 

 in a specimen from this colony — the precise locality is un- 

 known. It occurs in groups of small acicular crystals with 

 native copper. 



Chai.cocite (JRedruthite) . 

 As far as I am aware, this mineral has not been met with 

 crystallized in the colony. The massive variety is of frequent 

 occurrence in the copper mines of Yorke Peninsula — fine 

 specimens being obtainable more especially from the Moonta 

 Mines. Burr mentions it as occurring at the Xapunda, Monta- 

 cute, and Burra Burra Mines, and also at Mount Barker.
