MANGANKSE DErOSITS OF INDIA : DESCKII'TIVE. [PakT IV : 
miation of the Milndri band. In airprobability, when the intervening 
ground is opened up, the Milndri and Panchala deposits will be found to 
be continuous. At the time of my visit, December 190G, very little 
work had been done on the Panchala ores. It showed, however, that 
instead of dipping steeply to the deep as at Mandri, the ore-band is 
probably rolling gently about axes running east-south-east, and is therefore 
probably kept at the surface over a considerable width. Thus, at the 
eastern end there were two openings situated about 150 yards apart 
measured across the strike. In each of these openings the rock was 
evidently rolling, gentle anticlines and synclines being visible. It is 
therefore possible that the intervening ground is occupied by these 
rolling ore-beds. It is also possible that these excavations are on 
separate ore-bands. 
There seems little doubt that there is a large quantity of mangani- 
ferous rock in the Panchala area. A considerable portion of this con- 
sists of very hard rhodonite and spessartite-bearing rocks, massively 
bedded, and often partly altered to manganese-ore, the rocks being very 
similar to those of Manegaon. There is also a large quantity of ore, 
partly hard and crystalline (braunite-psilomelane mixture), and partly 
sooty and speckled in appearance like that of Mandri. 
In the workings at the western end the ore-beds were seen to rest 
on felspathic mica-schist, whilst in one place two lenticular masses of 
mica schist, each a few yards long and up to 3 feet thick, were seen to be 
included between the layers of ore. The maximum thickness of the ore- 
layers seen was perhaps some 15 feet, but this is not necessarily the full 
thickness. Mr. Coggan informs me that the analysis of the ore extracted 
during 1906 is as follows : — 
Manganese . . . . . . . . . 47 • 58 
Silica .......... 8-57 
Phosphorus 0 ■ 109 
The ore has to be carted J to 1 mile to the steam-tramway at Mandri.
