Newelltown are obtained specimens of decomposing argentiferous 
galena, similar to that found in Derbyshire, England, to which 
Dr. T. Thompson gave the name of supersulphuret of lead. 
Galena occurs in auriferous quartz on the Hodgkinson goldfield; 
also with iron pyrites, sphalerite, and chalcopyrite (auriferous) in 
the Currency Lass, Ravenswood ; with similar associated minerals 
in quartz and steatite in the Politician claim, Ravenswood ; with 
cerussite in the Ravenswood Silver Mining Co.’s claim, assaying 
350 to 400 ozs of silver and 2 ozs. of gold to the ton; with iron 
pyrites in auriferous quartz on Charters Towers ; with iron pyrites, 
sphalerite, quartz, and calcspar, assaying 3 ozs. of gold to the ton 
on the Norton goidfield ; with auriferous iron pyrites in quartz at 
the Welcome Company’s Mine, Mornish, Rockhampton; with 
iron and arsenical pyrites and zinc blende in the Allendale lode, 
Chowey Creek, assaying 39 ozs. of silver and 1 oz. of gold to the 
ton ; in Hannan’s lode in the same locality assaying 50 per cent. 
of lead, 30 ozs. of silver to the ton, and a little gold ; with 
chalcopyrite in quartz yielding 4 ozs. of gold per ton by crushing, 
at the Ellen Ross, Ravenswood. 
On the Hodgkinson goldfield gold occurs with galena in quartz 
at the Hit or Miss, on galena in quartz in the Black Ball, and in 
quartz associated with galena, mispickel, and sphalerite at the 
Union Reef. 
In the Bryan O’Lynn, on the Queen Reef, Charters Towers, 
gold has been found in scattered grains among crystals of iron 
pyrites and galena. Gold with galena on quartz has also been 
obtained from the Gilbert goldfield, on the Boyne River, Glad- 
stone, in the Etheridge district—where galena, cerussite, malachite, 
and limonite accompany gold in quartz—and in the Burdekin 
district. Specimens of galena with cerussite from the Ravenswood 
goldfield sometimes shew a coating of very thin gold on parts. 
Galena is also found accompanying gold on Gympie, being 
associated with iron pyrites, quartz, and calcite.
