M.ANGANESE DEPOSITS OF INDIA : DESCRIPTIVE. [PaET IV : 
Katangjheri village. ^ The outcrop is about | to | a mile long and is not 
quite continuous. It lies on low ground, but rises here and there into 
small hillocks. The north-west end (.'f the ore-band lies close to a 
nalii and hero the strike is S.30°E. Further along, the strike changes 
to about E.35°S. and then returns to S.SO'^E. in the south-east 
half of the deposit. The dip is everywhere to the north-east side of the 
band, the amount varying from 30° to GO''. 
The outcrop varies in character. At the south-east end it consists 
of coarse grey quartzite with thin bands of yellow spessartite, but in 
many other places the spessartite-bearing rock is partly altered to oie. 
In one place about the middle of the outcrop red spessartite in quartz 
is to be found. 
At one point only was there exposed any manganese-ore of possible 
value. This was on a small hillock near the north-west end of the 
outcrop. A sample broken, off the outcrop on this hillock consisted 
of the dirty speckled ore composed mostly of black oxides and dull grey 
psilomelane with a little braunite and lead-like psilomelane. The 
analysis made at the Imperial Institute shows : — 
Sam-pie No. 59.

and indicates a content of only 13 per cent, of braunite. 
Considering the very limited quantity of ore indicated in this hillock 
and us oitaation, it is doubtful if it will be worth working, except at 
times of high prices ; unless, of course, opening it up should lead to un- 
expected developments. 
1 Or about 1 mile north-north-west of the Katangjheri marked on the 1" map dated 
1870. This latter, however, is now only the iola or hamlet, the main village being that 
shown to the north of the pond.
