be good in quality throughout its entire length, and is nowhere, as far as can bo 
judged from the surface, less than 6 feet in thickness, and is mostly a good deal 
more. The ore consists of carbonate (chiefly green), but there is some blue also 
in the poorer parts of the lode, while in the rich some beautiful specimens of 
malachite have been obtained. Considering its proximity to the coast (15 miles), 
the comparatively shallow depth at which good water can be obtained, and the 
enormous mass of rich ore in sight, this should prove a very valuable property. 
Some copper mines were worked a few years ago a few miles South of 
Roebourne. They are situated at the base of some low slate and quartzite hills on 
the edge of a large flat formed by one of the branches of the Harding River. 
These lodes are chiefly oxides of iron and copper, in some of which gold is visible. 
There are two sets of lodes, one running more or less North and South and dipping 
East, while the other runs East and West and dips North. 
A good deal of work was formerly done here, but has been lately discontinued 
owing to the low price of copper, but as the ore at the surface is very fair, and the 
lodes are large and near a port, they could be worked cheaply; and now that 
copper is realising a higher price they might certainly lie re-opened. In any case 
the one containing gold should be worked, as that metal can be now separated 
from copper so much more economically than it coidd twenty years ago. 
Large ferruginous copper lodes occur all over this district, some of which 
carry from 30 to 40 per cent, of the metal, but the mass of the lode stuff is iron. 
In some of the specimens gold is plainly visible, and, judging from the assays, 
would be well worth working. The galenas and cupriferous gossans of this district 
are also well worth testing.

Kimberley. 
In the Kimberley District, copper and lead ores are associated with gold, but 
only in small quantities. The gold is in a free state, and in the rich specimens is 
plainly visible to the naked eye. 
Some very fine copper ores exist in this district, but the present expense of 
carriage is too heavy for them to pay. 
Mt. Barren. 
Near Middle Mt. Barren a copper mine was started, and a good deal of work 
done on a lode, but hard coast ranges are not of a highly promising character for 
valuable minerals. 
Copper occurs in the Wongan Hills, the Darling Range, the Glenelg Range, 
as well as in several other places. 
TIN. 
The Greenbushes Tinfield. 
Area, 50 Square Miles. 
In the latter part of the year 1888, Mr. Stinton, whilst kangaroo hunting, 
found a small quantity of stream tin in a gully near the Blackwood River, not far 
from the main road, about nine miles from Bridgetown and 53 from Bunbury. 
A large number of leases were at once taken up, but as the old regulations did 
not contain any labour clauses, very little work was done.
