MITCHELL ANTIMONY MINES. 
Information has recently been received to the effect that very important dis- 
*^overies of auriferous antimony ore have been made by Mr. J. V. Mulligan and others, 
the Mitchell Eiver near the Limestone Gold Mines, 
MOUNT ALBION SILVER EIELD. 
\Tr ^6st of the stanniferous porphyritic and granitic country of Herberton and 
‘^tsonville, a band of stratified rocks stretches north-westward from the head of the 
Kiver. They consist, for the most part, of shales and siliceous grits, the latter 
Occasionally altered so as to be almost quartzites. Their general strike appears to be 
^ona north and south to north-north-west and south-south-east, but at Mount Albion 
®clf, which is the most highly mineralised portion of the district, the rocks (among 
'ch siliceous grits predominate) have been minced up by innumerable faults into 
®cgroents, in each of which the strata have their own peculiar dip. In the Mount 
^on Mine some sandstones are marked with reed-like plant-impressions, but nothing 
yet been discovered sufficiently distinct to afford any positive evidence as to the 
of the deposits. 
In the principal mines on Mount Albion — viz., the Albion, Lady Jane, and 
^^®irossa — immense deposits of ore occur in a very irregular manner. It appears that 
c faults are even more numerous than the evidence observable at the surface would 
an that the ore has filled up fissures formed by faults which intersect one 
^ c ner in every direction, so that there are no definite walls which can be followed for 
e The ores are earthy and ferruginous, with argentiferous lead oxides and 
onates, and probably a good deal of silver chloride in fine particles accounts for 
u cccasional extraordinary richness (600 or 700 oz. of silver to the ton). Large 
AlV^*” ^lorn silver are met with from time to time in the workings. In the 
®o™e were obtained at the surface and at the depth of nineteen feet. In the 
®iahf some were obtained at the one hundred and thirty and one hundred and 
^ow levels. The mines have not yet reached the water level, which is probably 
mount being well drained by the faults which intersect it in every direction. 
®res oxides and carbonates, therefore, predominate, sulphide and sulphate 
onl* except in the Barossa (where the galena is associated with zinc-blende), 
7 3' small proportion of the ore. 
ogg marked contrast to the deposits of ore on Mount Albion are those which 
a mile and a-half to the south-east. A large lode, the Silverhill, which 
® taken as a typical example of what is meant by a true fissure lode, runs north 
®®uth through slate country, underlying at 45° to W. It is distinctly traceable
