lEON ORE AJS^D COAL DEPOSITS AT WALLEEAWANG.

A sample of the ore taken from the heap at the shaft's mouth, 

 just as it was raised, and without having undergone any dressing 

 process, yielded on analysis the following results : — ■

If for any special purpose a richer and purer ore be required, 

 the nodules could be readily separated from the loose ore before 

 it is sent to the surface. As shown by the following analysis, these 

 nodules are much richer, and contain on an average 51'52 per 

 cent, metallic iron.

As will be seen from the above analysis, this brown hematite 

 contains but very small proportions of phosphorus and sulphur, 

 and far less than the well known Northamptonshire brown iron 

 ore. 



Probably it will be found feasible and economical to work 

 much of this deposit as a quarry in stopes, on account of its 

 great vfidth, and because it is favourably situated on a hill side. 

 By this method expensive shafts and galleries can be dispensed 

 with. 



* Equivalent to 37-84 per cent, metallic iron.
