The following are some analyses, supplied by Mr. Aubert, of hand- 
specimens of ores from the Riimandrug deposit. They were picked 
to illustrate various types of ore. The analysts were Messrs. W. H. 
Pearson of London : —

From these it may be concluded that the average figure for the 
Ramandrug ores is — 
Manganese ........ 45 
Iron 12 
Silica ......... 1 
Phosphorus ........ 0-02 
But I believe that in actual practice the ore is found to be of lower 
grade than this. 
The chief characteristics of the Ramandrug ores are thus seen to 
be the high iron, and very low silica and phosphorus. Besides 
ores corresponding to the foregoing analyses, large quantities of ores 
of much lower grades are also mined. They are characterized by lower 
manganese and correspondingly higher iron, but except occasionally are 
not at present made use of. Every grade of ore ranging from 
manganese-ores of the above composition through manganese-ores 
very high in iron and manganiferous iron-ores, to iron-ores very low 
in manganese, could be obtained, were there a demand for them.
