is brought to England from the Continent, and from which the cobalt is 
saved as a by-product. 
The demand for nickel, to be used in the manu- 
facture of the basis of plated ware, is steadily increasing, while the 
demand for cobalt is daily diminishing, on account of the artificial blues 
introduced for the use of the dyer, calico-printer and papermaker. Still 
our cobalt-ore might be economically used—the saving being moderately 
easy, where it occurs in quartz reefs worked for gold, as at Alexandra 
diggings, where it coats the joints of the quartz with a botryoidal coat- 
ing of considerable thickness—by passing the tailings through settling 
boxes, in which it would settle with the last of the gold, and be in an 
excellent form for removing gold from tailings by Plattner’s chlorine 
process. 
rine in chemical works. 
The residue would also be of value for the generation of chlo- 
After either of these operations the cobalt could 
be saved. A process kas been invented and tried in South Australia, in 
which the cobalt is extracted by smelting the ore with copper and, I 
believe, separating the metallic cobalt by liquation; but I have not heard 
that it has been attended with success.” 
85. MOLYEDENITE ` (Sulphide of | 89. Actcurar BLACK SULPHIDE 
Molybdenum). 
Yea, Goulburn River. 
Occurs associated with iron pyrites 
in granite. 
86. MOLYBDENITE (Sulphide of 
Molybdenum). 
Yackandandah. 
This mineral contains, according to 
assays, a small percentage of silver. It 
occurs in hexagonal plates in a quartz 
vein traversing granite.

Molybdenum). Map No. Mu 8. 
Close to the Maldon Brewery 
Springs. 4 sheet 14 N.W. 
Occurs sparingly dispersed in small 
scales through the granite. 
87A. CERVANTITE (Antimony-Ochre 
—Oxide of Antimony). 
Costerfield, near Heathcote, 
Occurs coating antimony-glance, and 
also in veins, but not below the water- 
level.

From the upper workings. 
OF ANTIMONY. 
Costerfield. 
Occurs sparingly in the steel-grey i 
variety of the sulphide from the lowest 
workings.

Antimony-Ore — Sulphide of 
Antimony). 
Costerfield. 
Crystals, coating the faces of joints of

Wood’s Point.

phide of Antimony). 
Doogalook, Yea. è 
Presented by Mr. Verdon. 
Note—Antimony is generally found in connection with auriferous 
quartz, and is frequently impregnated with specks of gold. Assays have 
shown as much as 8 ozs. of gold and 80 ozs. of silver per ton.
