45. BARITE (Sulphate of Baryta or Heavy Spar). 
Occurs at many localities throughout the north-western portion 
of the island. It is very plentiful at the Surrey Hills, where it 
often contains Copper Pyrites and minerals resulting from the 
decomposition of the same, such as black oxide and the carbonates. 
At Mt. Lyell it occurs with Gold in large compact masses; in 
veins under Mt. Roland, Rocky River, and near Corinna, Pieman 
River; at the Wilmot River, where Native Copper is found 
associated with it; at the Specimen Reef Mine, Savage River, 
often containing cupriferous pyrites and sometimes Gold; with 
galena, Huskinson River; with Pyritesand Galena, near Deloraine; 
with Calcite, Siderite, and Galena, on the banks of the Upper 
Leven River. 
46. BASTITE—see ScHILLER SPAR. 
47. BLENDE—see SPHALERITE. 
48, CHALCOPYRITE (Sulphide of Copper and Iron). 
Much of the mineral substance known under this name is more 
properly Cupriferous Pyrite, the pure chemical compound being 
comparatively rarely met with. It is the common ore of Copper, 
which here, as in most other metalliferous countries, is freely dis- 
tributed, although the crystallized pure form is but rarely seen. 
Although copper, probably this ore, was known to exist in the island 
as far back as 1822 (Evans’ Description of Van Diemen’s Land), 
no profitable results have followed the few attempts that have been 
made to open up the discoveries of the ore at Mount Maurice, 
Badger Head, Saxon’s Creek, kc. Al] have been abandoned after 
the expenditure of a limited amount of capital, so that the real 
value of these deposits still remains an open question. The more 
important localities are :—Mackintosh River, with. Baryta and 
Calcite ; Mainwaring Inlet ; Cascade River, with Cassiterite and 
Schorl; Mount Ramsay, auriferous in Hornblende; Badger Head ; 
Frankford; Mount Lyell, with Galena and other minerals; Penguin 
River; Lake Dora; Beaconsfield; Mount Maurice, with Cassiterite 
and crystallized Quartz; Mount Heemskirk; Arthur River; 
Scamander River, with Galena, Blende, and Arsenical Pyrites ; 
Blue Tier; near George’s Bay; Bell Mount, west of Mount 
Claude, where it occurs in rather large quantity as rounded lumps 
in alluvial drift with free gold; occurs in a lode at Mount 
Bischoff with Mariatite, Berthierite, and Chlorophane. 
49. CANNEL COAL (2) 
An important discovery has recently been made of a bituminous 
substance bearing a very close physical resemblance to the valuable 
Cannel Coal of England and Scotland. It was found in the form of 
loose surface blocks—supposed afterwards in situ—by the prospectors 
sent out by the Mole Creek and Zeehan Mineral Prospecting and 
Exploration Company, Limited, at Barn Bluff, near Mount Pelion.
