=Australia and Norway.=--The first official record of a production of
molybdenite in _Queensland_ was in 1900, when the output amounted to
12.3 short tons of high-grade material. The production gradually rose
to 119 tons in 1906, and has not varied materially since that date,
although the selling prices for concentrates increased considerably.
The bulk of the material was mined at Wolfram Camp, in the Chillagoe
field, 120 miles southwest of Cairns, in Northern Queensland. The mines
at Bamford, in the same field, are credited with a small output. With
the molybdenite ores are bismuth-tungsten ores, so that all three
metals are produced.
The production of molybdenite was first reported in _New South Wales_
in 1902; in that year the output was 17 short tons. The total output
to the end of 1914 was 498 short tons, valued at $264,000. The chief
producing molybdenite mines are at Whipstick, in the Pambula division,
at Kingsgate, in the Glenn Innes division, and near Deepwater, in
the Deepwater division. Molybdenite is also being produced at Rocky
River, in the Tantafield division, and in the Bathhurst division. The
production at all of these localities has not been large--in no one
year exceeding 100 tons of concentrates.
In _Norway_, the production of high-grade molybdenite concentrates has
averaged about 30 tons per annum since 1902. In 1906, an output of
1,129 short tons was reported. This probably refers to ore mined and
not to concentrates produced.
The chief molybdenite districts in Norway are the provinces of Lister,
Mandal, and Nedenes, on the extreme southern end of the peninsula. The
district of Fjotland, in the former province, is probably richer in
molybdenite than any yet discovered in Norway. A mine at Knaben, in
this district, has been the largest and probably the only successful
producer in Norway. This mine, owned by George G. Blackwell & Sons, of
Liverpool, England,[94] has made an average output of about 25 short
tons per annum.
