it would determine its value and downward extension. Iron ore can 
be traced continuously in a north-westerly direction for a total length 
of 3,600 ft. 
Several addi¬ 
tional outcrops of 
iron ore, invariably 
associated with 
silica and jasper, 
and on the same 
general line of 
strike, outcrop be¬ 
tween the south¬ 
westerly termina¬ 
tion of the Mt. 
^NTowa ISTowa out¬ 
crop and Boggy 
Creek. At 6 miles 
70 chains north¬ 
wards from Mt. 
N^owa ISTowa, along 
the tourists’ road 
to Buchan, there is 
a well-defined out¬ 
crop about 100 ft. 
in width, consisting 
of micaceous iron, 
limonite, and hae¬ 
matite of good , .. 
quality. The strike 0 /f^ad^eseaM

some miles a 
little east of north 
of the last-men¬ 
tioned locality, and 
has been the sub¬ 
ject of reports by 
Messrs. Murray^, ^owa-Nowa 
Jenkins^, and 
Dunn^. It consists of an outcrop extending along a length of nbout 
1,000 ft., with an average width, projecting above the surface, of 30 ft. 
It is composed of haematite, limonite, manganese-iron ore, and man¬ 
ganese dioxide. Where visible the Lower Devonian ash beds for several 
hundreds of feet on either side of the main body are highly stained by 
iron and manganese oxides, and these are surrounded on the western 
side by an extension of the Tertiaries from the ‘‘Yellow-Water-Holes.” 
The subangular and waterworn quartz pebbles and ash fragments of 
these drifts have been cemented into a conglomerate by the leaching of 
the iron. An outcrop of barytes occurs to the sQuth.
