MANGANESE DEPOSITS OF INDIA : DESCRIPTIVE. [ PaRT IV : 
The deposits all lie in the southern extension of the Chitaldrug or 
Dambal-Chikniiyakanhalli belt of Dhslrwra rocks ; and all lie to the east 
and S. E. of Chiknayakanhalli, within a radius of 12 miles. They 
are also all situated to the north of the Southern Mahratta Railway 
line from Birur to Bangalore. The stations to which the ore is 
carted are Banasandra for most of the deposits, and Yelladbagi for a 
few of them. The deposits can be divided into three groups : — 
The Chiknayakanhalli Group: — 
1. Honnebagi. 
2. Hoshalli. 
The Karekurchi Group: — 
3. Sondenhalli (Solid Hill mme). 
4. Muskondli (Rowe's mine). 
5. Karekurchi (Camp mine). 
6. Hattyal (Temple Hill mine). 
7. Haienhalli (Government Road mine). 
The Kondli Group : — 
8. Mavinhalli. 
9. Kondli (Donkey mine). 
10. Kondh (Government Hill). 
11. Shivasandra (Dodguni). 
The names given in brackets are those by which the deposits are 
known to the Peninsular Minerals Company. Of the deposits enum- 
erated above, Nos. 1, 2, and 3, are in the Chiknayakanhalli taluk, 
Nos. 5 and 6 in the Tiptur taluk, and the remainder in the Gubbi 
taluk. My visit to this area being limited to one day, I was able to 
visit the deposits of the Karekurchi group only and consequently 
shall not refer further to the others. 
It will be seen from the descriptions given below that the ores are 
very irregularly scattered through the rocks in which they occur, and 
that they are very much mixed with limonite, and residual patches 
of quartzites and argillaceous rocks. In fact their average quality 
cannot be high, probably not more than 42 to 45°/„ Mn as despatched. 
They must also be fairly high in iron, but may, if well selected, be 
fairly low in silica, though there must be a tendency for this constitu- 
ent to run to very high figures when pyrolusite-impregnated quartzites 
are mistaken by coolies for pyrolusite and mixed in with the other 
ores.
