GRAPHITE—Comp. carbon with oxide of iron and siliceous matter. 
Small quantities of graphite occur at Stanthorpe, but large 
amounts are found at Mount Bopple, between Maryborough and 
Bundaberg, the deposit or accumulation being said to attain a 
thickness of 30 ft. between the walls, which are micaceous granite. 
Graphite is also mentioned by Mr. R. L. Jack as occurring in 
lat. 20° to” S., between the Dugald and Leichhardt waters. It has 
also been found on the Croydon goldfield, and in the Smithfield 
United, Phcenix P.C., and other mines on Gympie—in association 
with gold on ‘‘slickensides.”

STIBNITE—Compp. Sb, S,. 
Stibnite has been found at Neardie, near Gympie, on the Stuart 
River, and with valentinite on S. John’s Creek, both these localities 
being in the Burnett district; also within four miles east of the 
township of Ravenswood. 
Galena accompanies stibnite in the Victoria claim, Silverfield, 
Tinaroo; this is an uncommon association. 
From the Emily Lease Antimony mine, at Northcote, in the 
Hodgkinson district, huge quantities of stibnite have been taken 
out. This mine was originally opened to work for gold, but less 
than 1 oz. per ton was extracted by crushing, so work was carried 
on for the sake of the antimony ore only. I find no mention of 
the value by assay of the ore for gold, but can easily understand 
that only a very small amount of the gold would be extracted if 
crushing was the only means used for the reduction of the ore. 
Gold occurs also in the same locality with stibnite, at Craig’s. 
Lease, and the Minnie Moxham claim, of which the former is on 
the Emily line of reef; from the latter the average yield was over 
2 ozs. of gold per ton, the value of the gold being from 43 19s. 
to £4 per ton. 
The association of gold and stibnite is not common, but it 
occurs in New South Wales, Victoria, Brazil, Transylvania, and in 
the Kingdom of Siam. 
MOoLyBDENITE—Comp. Mo S,. 
This mineral occurs in quartz, and sometimes with arsenical 
pyrites at Stanthorpe; with wolfram in Young American, Herberton; 
in quartz near Ipswich; and in large quantities, it is stated, some
