Out of over 70,000 tons of ore shipped by the New Mysore Mangan- 
ese Company up to the end of 10th August 1907, some 4,000 tons only 
were mined from Short's Block.

In 1899, Mr. H. K. Slater discovered an occurrence of manganese- 
ore near Kumsi.' This he examined more closely in 1903. Owing 
to the heavy jungle and covering of rich brown soil the dimensions of 
the deposit could not be properly ascertained ; but Mr. Slater reported 
that : — 
'it is undoubtedly of considerable extent and a very pure form of the oxide is 
obtainable.' 
' A large number of smooth rounded lumps of ore are to be found in the bed 
of the Nulla at the north-eastern base of the hill If miles E. N. E. — N. E. of 2805 
or 3 miles N. N. E. of Kumsi. ' 
In 1904 prospecting licenses were taken out for various blocks in this 
area by Messrs. Holmes, Short, and Norton. Prom these, the deposits 
have passed successively to the Madras Mysore Mining Syndicate, the 
Mysore Manganese Company, Limited, and the New Mysore Manganese 
Company, Limited, the last named of which now holds them. The 
ore has been located in situ on the northern slope of the hills north of 
Kumsi, at a point 3^ miles N. by a few degrees W. of Kumsi, and H 
miles N. by a little E. of hill 280.5. The geology of the country 
immediately surrounding the deposits is much obscured by jungle; but 
such cuttings as are available indicate that the rocks are phyllites and 
fine-grained schists, vitreous quartzites, hematite- and magnetite- quart- 
zites, and dolomites. The strike of these rocks as mapped by Mr. Slater 
is on the average about north and south. This also agrees with 
my observations. This strike is interesting to note, because the strike of 
the manganese-ore deposit seems to be, as far as one can judge from the 
obscure indications exposed in the workings, about west by a little 
south. If this be the true strike of the deposit, and it has been formed 
by replacement of the Dharwar rocks at the sxirface, then it means that
