MINERALS OF QUEENSLAND. QAT 
the Rise and Shine Reef very good specimens of gold 
were obtained in the upper part; lower down the stone 
changes to a mundic consisting greatly of zinc-blende, 
with some iron pyrites and a little galena.” . . “ Most 
of the work at Kilkivan has been the driving of tunnels 
in a sheet of white porphyry which occurs in the face 
of a range running north and south. There are no 
defined reefs at all in the porphyry, but only minute 
veins of quartz, with oxides of iron and manganese. 
Where the manganese di-oxide occurs, the veins are the 
richest in gold. In some parts of the porphyry these 
veins are very numerous, and the veins are very patchy. 
Where these patches occur, however, the whole of the 
mass will pay to crush” (R.) ; Kilkivan ! !, associated 
with oxide of manganese in a white felspar (R.) ; 
Gympie g.f.!!!, in reefs traversing grey shales, black 
pyritous shales, greywackes, sandstones, grits, and 
conglomerates of Carbonifero-Permian age, the richest 
deposits of gold occur where the reefs intersect the 
pyritous black shales (J.); No. 1 N. Lucknow Mine, 
Gympie !, associated with asbestos (R.); Brovinia g. f. 
!!!, in reefs (J.); Hidsvold g.f. !!!, in reefs in granite 
country, with galena, pyrites, arsenical pyrites and 
stibnite (R.) ; Mount Shamrock g.f.!!!, im lodes con- 
taining quartz, hematite and bismuth oxide,—‘ The 
gold appears to be especially associated with the bismuth, 
for the veins of oxide of bismuth are exceptionally rich. 
A small sample of the oxide assayed by Mr. Hamilton 
contined 62 per cent. of metallic bismuth and 252oz. 
of gold per ton of the material” (R.); Mount Sham- 
roek !, in molybdenite (L.); Old Chowey Reefs, Wide 
Bay ! !, in molybdenite in quartz (R.) ; Crocodile g. f.!!!, 
reefs partly in granite and syenite country and partly 
in slates, greywackes, grits, and conglomerates inter- 
sected by diorite dykes (J.) ; Rosewood g. f. ! ! !, Golden 
Bar Reef, of calespar, with chlorite in pockets and 
coating calcite crystals, occasionally a good deal of 
quartz, some very rich specimens of gold in calcspar, 
the reef occurs in a diorite dyke for the most part 
altered to chlorite—Caledonian Reef, quartz with patches 
and pockets of chlorite, country rock altered sand- 
stone (J.); Blackfellow’ Gully !!! (J.); New Zealand 
Gully !!!, North Star Mine, in porphyry country (J.) ; 
Last Chance Reef, gold disseminated through a mass of 
chloride of silver (D.); Cawarral!!!, in serpentine 
country, also alluvial gold (J.); Canoona g. f.!! 1, 
‘‘when (in alluvial workings) found with the matrix 
attached, matrix was serpentine” (R.); Mount
