All these deposits, except 22a and 32, will be found indicated by their 
numbers on the map (Plate 43), of the Ntigpur-Balaghat area. In 
addition, manganese-ore was found at Warpani during 1907. 
The ores found in this district consist typically of mixtures of braunite 
The nature and psilomelane. Such ores may be either very 
quality ( f the ores. fine-grained, when it is very difficult to make out 
what is the mineral composition, or they may be more coarsely cry- 
staUine owing to the braunite 's being present in larger crystals. In some 
cases the ores are very coarsely crystalline as at Lohdongri, and consist 
almost entirely of braunite, usually with a certain amount of interstitial 
psilomelane. More rarely the ores consist entirely of psilomelane. 
The best locality for such ore is Guguldoho. Amongst the composite 
ores there is also the one I have referred to as speckled ore, composed of 
a crystalline mineral such as braunite or mangan-magnetite (?), set in a 
matrix of psilomelane and soft black powders (see page 696). Other rarer 
ores are the crystalline manganate, hollandite, found chiefly at the 
deposits of Group VI, especially at Junawani ; and pyrolusite, the best 
locality for which, not only in this district, but also in the whole of India, 
is Pali, where it occurs in crystaUine limestone. Other minerals are 
vredenburgite and beldongrite both found at Beldongri ; and possibly 
mangan-magnetite, as for example, at Gtxguldoho. 
I took samples from nearly all the deposits visited. A few of them, 
in cases where the deposit had not been much opened up, were taken 
by breaking pieces off the outcrops, but the majority were taken from
