Associated Rocks. 
The rocks with which it occurs are very similar to those associated with the 
other coal seams of this Colony, viz., white sandstone, ferruginous sandstone, 
micaceous sandstone and clays, dark shales and tire clays. 
Extent. 
This belt of country appears to rim in an East and South-East direction at 
the back, or to the Eastward of the Darling Range, but it does not extend far 
towards the North. To the Southward it appears to extend at first in a more 
South-Easterly direction, crossing the Blackwood from 10 to 20 miles to the East¬ 
ward of Jayes, and so on in the direction of the Franklin River, where it is cut off 
and turned to the South-West by a bold mass of crystalline rocks, through which 
this river has cut its channel. 
Means of Export. 
The nearest port is Bunbury. The road is very good for 15 miles to the 
Collie Bridge, after which it has to cross the high rough Darling (about 1,000 
feet), but no doubt a much better road could be found. 
Should the field prove to extend far to the Eastward there is no doubt but 
that a branch line would be run from the Great Southern, as the country is 
comparatively flat. 
Timber and Water. 
Timber suitable for mining purposes is in great abundance on the field, and 
some of the finest tracts of jarrah country in the Colony are to be met with 
close by. 
As to the question of water, it is in such abundance that it will probably be a 
great source of trouble in some places, but when a coal seam is met with in the 
solid country, between two good shale beds, it will not come in so fast. 
This field is now being tested by the Government. 
IRON. 
This is essentially an iron country, for one cannot travel a mile in the parts 
where the older rocks appear at the surface, without encountering a lode. 
It occurs in many forms, but the chief are magnetite and hematite (black and 
red oxides), which occur in immense lodes, and would be of enormous value if cheap 
labour were abundant. There is enough to supply the whole world, should the 
present sources be worked out. 
From the large quantity of iron in this Colony it is almost impossible to work 
with any degree of accuracy .with a magnetic compass. 
ANTIMONY. 
There are some very good lodes of stibnite (sulphide of antimony) m the 
Roebourne District, and their value in most cases is greatly increased by the 
quantity of gold they contain. They have not been worked yet, having often been 
put down as small lead lodes.
