76 CATALOGUE OF MINERALS ; 
iron pyrites, and mispickel in the Buck reef. In the Gilberton 
district is a copper lode, running east and west with a width of 
50 feet, said to contain 71 per cent. oxides and carbonates of 
copper, or 58 per cent., of metallic copper (Staiger). Very good 
specimens of malachite has also been found in the Normanton 
district. 
The Cloncurry district, so noted for metallic copper and cuprite, 
is not backward in the production of malachite; in the Great 
Australian mine the cap of the lode is composed of a siliceous 
matrix with green carbonate of copper; the Contra lode has a 
large cap of ironstone with much green and some blue carbonate, 
while at the bottom of a 20 ft. shaft on the lode pale red oxide 
with some copper pyrites and much green carbonate are found ; 
the ore of the Homeward Bound copper lode is green and blue 
carbonates with some red oxide and native copper, said to have 
contained gold as does the green carbonate ore of the Flying 
Dutchman. The ore from Argylla Creek, some miles fron. Clon- 
curry, contains a good deal of malachite, often radiated and 
fibrous and of the highest possible percentage. A specimen in 
the Queensland Museum of malachite from Cloncurry shews gold 
embedded in it; other specimens from the same locality are 
pseudomorphs after cuprite, azurite, and siderite. I find that 
specimens of massive cuprite, or native copper changing to 
cuprite, from Cloncurry are very liable to be encrusted with 
malachite after keeping for a short time in the atmosphere of 
Brisbane. 
From the Kennedy copper mine, on a ridge near Sandy Creek 
to the west of the Great Star River, a very pure malachite has 
been obtained. In the Tinaroo district malachite seldom occurs 
in large masses, but not unfrequently is found as a staining or 
incrusting mineral. 
Mr. D’Oyley Aplin, in his report on part of Burnett district, 
mentions the occurrence of serpentine coated with malachite 
near Ban Ban. 
I may remark here that Queensland malachite of fibrous 
structure is frequently of such a dark green colour as easily to be 
mistaken at first glance for atacamite ; I have seen one specimen 
containing gold brought from the Palmerston copper mines, in 
which the dark green matrix was supposed and appeared to be 
atacamite. This association of gold seemed so rare that I 
examined the specimen and found it to be only malachite.
