of Victorian Auriferoiis Occurrences. 35 



near Avoca ; among those from this locality there is a little tetra- 

 dymite. Bismuth minerals witli traces of tellurium occur also at 

 Mallacoota (4) and tetradymite is also recorded from Maldon (4). 

 A part of the bismuth at Maldon occurs in the rare mineral 

 maldonite (2). Native bismuth, bismuthinite, bismite and 

 bismutite are recorded from Maldon. 



9. Wolfram. — In the localities of which I have most detail 

 this mineral is associated with one of the preceding groups, but 

 it seems best to place it separately. There is no evidence of any 

 influence on gold contents, and it would probably be of moie 

 value for itself if in quantity than for its influence on the gold. 



The following examples show the minerals of the last three 

 groups associated with one another. 



Reef on Sandy Creek, Maldon. — Native bismuth, hematite, 

 schorl and wolfram. No statement as to gold contents (1). 



Reef on the Nugget ty Range, Maldon. — Quartz, orthoclase, 

 schorl, mica, molybdenite, wolfram, scheelite. It is contained in 

 granitic i-ock. Gold is not mentioned {"1). Rock crystal and 

 cairngorm occur in the cavities. Reefs of this kind are no doubt 

 the source of the quartz crystals containing, in different instances, 

 molybdenite, scheelite and schorl, which have been found in the 

 neighbouring Bradford Lead. 



Superb Reef, Linton, near the granite, contains bismuth, bis- 

 muthinite, bismutite, molybdenite, wolfram, besides quartz 

 crystals containing schorl, and rutile (5). 



It may be noticed that the supposed columbite at Maldon has 

 been shown to be rutile (4), and that Ulrich records titanium 

 dioxide from Steiglitz (2). 



10. The material worked for mercury on the Jamieson River 

 consists, in samples I have received, of a clay rock with quartz 

 veins containing in both cinnabar and mercury. Gold is .said to 

 be present. Cinnabar is also recorded from near Bullumwaal, 

 found in small Ijroken fragments on the surface near a quartz 

 reef (4). 



Campbell's Reef, Moyston, is mentioned by Ulrich (2) as con- 

 taining strong irregular veins and patches of calcite, sometimes 

 with galena and pyrite (2). It would seem most likely that 

 these are analogous to the dolomite veins and patches at Ballarat
