40 CATALOGUE OF MINERALS ; 
a small sample of the oxide assayed by Mr. Hamilton contained 
62 per cent. of metallic bismuth, and at the rate, of 252 ozs. of 
gold to the ton of mineral, In the Allendale lode, iron and 
arsenical pyrites with galena and sphalerite assays 39 ozs. of silver 
and 1 oz. of gold to the ton. In the old Chowey reefs the quartz 
contains a good deal of molybdenite with which gold is associated, 
the molybdenite often containing specks of gold in its midst. 
As far as I am aware, this association of gold and molybdenite is 
without parallel. 
In the Gilbert district gold occurs in quartz with galena, but 
iron pyrites is its more usual matrix. In the Etheridge district, 
generally, gold has been found with galena, with azurite and 
cerussite, with calcite, with malachite and cerussite, and with 
malachite, cerussite, galena, and limonite; a highly decomposing 
auriferous pyrites also occurs, which I think is a mixture of 
ordinary cubical pyrites and marcassite. 
Specks of gold, probably derived from the disintegration of 
small gold-bearing quartz leaders or strings in the granite country, 
have been found in tin-wash of Pikedale and Stanthorpe, and an 
auriferous wolgram is said to occur at this latter place ; a specimen 
in the Queensland Museum is so labelled, but I am unable to find 
any record of analysis thereof. 
In the Cloncurry district one of the most remarkable associations 
of gold is with schorl; this, I believe, is only met with elsewhere 
at the Union Gold Mining Co’s lease, Crocodile, near Rock- 
hampton (where an auriferous iron pyrites occurs in schorl and 
calcite) and in the Akankoo reef, on the Ancobra River, port of 
Axim, West Africa. The schorl in both these Queensland locali- 
ties is accompanied by calcite. Bismuthite, malachite, limonite, 
hematite, calcite, sandstone, malachite and cuprite, and quartz 
are all found carrying free gold in the Cloncurry district. In the 
Uncle Tom gold-reef the stone is white glassy quartz with pockets 
of hematite, numerous veins of calcite, and chalybite. From the 
wash of the gullies draining into Pumpkin Gully metallic bismuth 
and gold are washed out. 
From the Last Chance reef, New Zealand Gully, near 
Rockhampton, specimens were obtained showing metallic gold 
disseminated through a mass of chloride of silver. (Daintree.) 
In referring to the occurrence of gold at Mount Morgan, I 
cannot do better than give excerpts from Mr, R. L. Jack’s report.
