THE GEOLOGICAL OCCURRENCE OF ANTIMONY ORES. 57
INDIA.
Antimony ore has been found in the following localities:—
Tenasserim, Shigri, Jhelum district.
AUSTRALIA.
New South Wales,—At a mine near Armidale, the vein varies in
width from 10 inches to 15 inches. The ore has also been found at
Hargrave's Falls and in the vicinity of Aberfoil. In the Macleay
district the veins have been successfully worked. In the Bathurst
district the ore occurs in blocks without any well-defined lode. On
the Munga Creek, the ore is found to be enclosed in a quartzose
matrix. (A.) East of Broken Hill, in the Barrier Range, the ore is
argentiferous. A vein occurring in the crystalline schists of this
region carries, wherever it cuts amphibolitic intrusions, rich silverantimony
ores, dysqrasite (Ag?iSbm), stromeyerite (CuAgS), and
antimonious silver chloride, the gangue being calcite and ironspar.
(B.)
Victoria.—At Costerfield, antimonial reef is found. At Whroo,
concretions of antimony ore are found in many veins. In this
remarkable instance the sulphide is enclosed in successive concentric
layers of oxide, with here and there scattered grains of gold. Stibnite
is also found at Munster Gully, Dunolly, and at Donovan's Creek;
the lode of the latter locality consists of nearly pure stibnite, attaining
to a width varying from 1 foot 6 inches to 2 feet. At S anbury, there
occurs a vein having an irregular course approaching to the strike
of the Silurian strata. This vein, 3 inches to 8 inches in thickness,
carries about 2 oz. of gold per ton. (B.) Auriferous antimonial veins
are said to occur 17 miles from Melbourne.
Australasia.—Antimony ores are also found in Queensland, New
Zealand, and New Caledonia.
SOUTH AFRICA.
Antimony ore is said to have been found in the Murchison Eange
in the Transvaal.
