MELACONITE—BLACK OXIDE OF COPPER—Comp. Cu O. 
Considerable quantities of melaconite have been noticed in the 
Mount Perry copper mines in association with chalcopyrite and 
bornite ; also at the Kennedy copper mine, near Townsville, 
where it occurs with a rather impure cuprite ; and at the Great 
Australian copper mine, Cloncurry, where it has been found 
crystallized. It has also been noticed near Mackay by the Rey. 
J. E. Tenison-Woods, F.G.S., &c., and it occurs in the Alliance 
mine, near Rockhampton, in auriferous quartz. 
CorunDuM—Comp. Al, O,. 
At Stanthorpe in the tin-drift sapphires of small size and uneven 
colour have been pretty numerously found, and also, I believe, at 
Herberton. On the beach near Southport emery occurs in fine 
grains but in considerable quantity (Hinchcliffe). 
HEMATITE—Comp. Fe, Oj. 
Occurs in small quantities in a number of places at Beenleigh, 
and in pseudomorphs after pyrites at Yatton. Near Mount Eurie, 
at the head of the Dugald River, micaceous iron ore has been 
found, and rather to the north of this, towards the source of 
Cabbage Tree Creek, between the Dugald and Leichhardt Rivers, 
immense masses of hematite occur. But the most remarkable 
occurrence of hematite is noted by Mr. R. L. Jack as follows :— 
“Mount Leviathan, on the left bank of the Cloncurry River, 
opposite the township, is a mass, say 200 ft. high and a quarter of 
a mile in diameter at its base, of the purest possible iron ore. 
The greater part of it is massive or granular specular iron ore, 
with only a few grains of siliceous sand. Specimens of foliated 
specular iron may be picked up, and parts of the mountain are of 
magnetite. The specular iron is frequently magnetic. Half a 
mile south of the township is a smaller hill of specular ironstone, 
equally pure.” An earthy red hematite and iron ochre form parts 
of the auriferous ore of Mount Morgan. 
Red hematite has been mined at Ravenswood for use in the 
smelting furnaces. From near Mackay specular iron ore occurs 
with malachite and limonite. Some of the hematites around 
Cloncurry are auriferous, some even containing visible gold, and 
near Normanton occurs a considerable amount of hematite which 
is expected to carry gold.
