traceable at the surface. The limonite appears to be associated with 
Tertiary drift. Shafts, one of 20 feet in depth and another of 15 feet, 
have been sunk on the limonite, and some trenches made, but insufficient 
work has been done to prove the full extent of the ore. About 3 acres 
of iron ore may be considered to exist there, varying in thickness. The 
appearances indicate a considerable bulk of ore that would prove of value 
if it could be utilized with other deposits, but it is not large enough to 
work by itself. The limonite apparentlv is derived from other rocks, and, 
as beds of what appears to be Heathcotian crop out alongside of the 
deposit and to the south, it might be worth while to open out and explore 
these beds, so as to discover if they are very ferruginous, as they are at 
some other localities. The outcrop extends for 15 chains in length in a 
north-easterly and south-westerly direction. 
From this spot the country is smooth and easy for road-making to 
the main road between Buchan and Bruthen. 
Still further in a southerly direction from Buchan, about 5 miles in a 
bearing of 12 degrees east of south from Dr. Mackieson’s house, is a 
high ridge, running northerly from a portion of the Mount Tara range. 
Here a belt of ferruginous, highly siliceous beds, approaching jasper in 
character, occurs. Probably these beds belong to the Heathcotian series; 
they are of considerable extent. 
These beds are rich in iron ore, but of a very siliceous nature, and non¬ 
magnetic. They are of dark red and purple colours, extremely heavy, 
and much jointed, and thev break readilv into angular fragments. Hsematite 
is probably present, as the streak is bright red. Beds of this nature cross 
the ridge, and they are met with for quite 10 chains along the course of 
the ridge. 
Further along the ridge, in a southerly direction, these beds give place 
to ash beds of Devonian age. 
About 7 miles south-east from Dr. Mackieson’s house is the Blue lode. 
It crops out near where the mining track from Nowa Nowa to the Mount
