Case 61. SUverton. — Many of the specimens from the various Silverton 

 mines show chloride of silver richly, but this has usually long 

 since blackened to such an extent as to almost escape notice. 

 1395, New Tear's Mine : an ironstone showing a coating of 

 blackened chloride, and assaying 2,30'3 oz. of silver per ton. 

 1399, Nolan's Mine : similarly shows the chloride on cerussite. 

 1420, Mascotte Mine: a mass of blackened spongy cliloro-bromide 

 in ironstone. 9401, Lake's Camp : shows chloro-bromide abun- 

 dantly in cerussite. 



VmheruinherJia. — The ore here consists of galena, sometimes 

 exceedingly fine-grained and with a fibrous structure (1445;, 

 with chalybite and cerussite. Native Silver is not uncommon. 

 6706 is a characteristic specimen showing galena and buff-coloured, 

 chalybite, vvath native silver dusted over the former, or occupy- 

 ing cavities. 1031, in case 125, is similar in character. Cerussite 

 sometimes occurs as dusky crystals seated on fine-grained galena 

 (1484) ; at other times it is massive (1496). 



1389, War Dance Mine, is traversed by veins of silver chloride, 

 the assay value being very high. 



8297, Mount Gipps : a bismuth-bearing ore, assaying 4,000 

 oz. silver per ton.* 



From the Pinnacles comes a galena ore associated with garnet 

 (1476), and hornblende with magnetic pyrites (8'J91). 



1599, Night Dream Mine, in case 125 : chloride ore. 



"Western Various silver-lead ' ores from Liddleton, near Hartley, Mount 



Werong, Wiseman's Creek, Eockley, &c., are exhibited ; ^ew, if 

 any, of these are now being worked. In the gossan from the 

 Lewis Ponds Mine (now abandoned), near Orange, native silver 

 (8270, 5392) and silver chloride (8271) have been obtained. 



* other instances of the association of silver with bismuth are the Jingera and Duckmaloi 

 ores respectively (see pages 53, b7, and case 60),
