quartz at the Sunburst P.C., both of these on Charters Towers ; 
with iron pyrites in quartz and in calcite at No. 1 and No. 2 South 
Advance, Norton goldfield, and with galena, iron pyrites, quartz, 
and calcite at the Advance P C., Hickey’s Reef, and the Frampton 
United Mines, a!l on the Norton goldfield. 
The following are analyses and assays of the complex zinc, 
iron, and lead sulphides from the Frampton United mines, by 
Messrs. Johnson, Matthey & Co. :—

Auriferous sphalerite occurs with galena and chalcopyrite in 
quartz at the Mary Florence, Rockhampton, and with galena at 
the Annie Claim, Cawarrah, Rockhampton. 
The ore of the Stockholm or Comstork reef, Charters Towers, 
contains a good deal of sphalerite in association with iron pyrites 
in minute crystals, copper pyrites, galena, and sometimes carbonate 
of copper. In the Bryan O’Lynn lease, Queen’s reef, Charters 
Towers, specimens have shewn specks of gold in the middle of a 
mass of crystallized zinc-blende. 
Sphalerite is by no means a common auriferous mineral in 
other countries, but it is very characteristic of the Ravenswood 
goldfield, especially when associated with iron pyrites, and is, 
indeed, not at all of uncommon occurrence in several Queensland 
goldfields. 
The mineral is generally brown or black in colour, subtrans- 
lucent, brittle, and having a small conchoidal fracture ; massive or 
compact in form, sometimes fibrous, rarely crystalline,
