mines of Ajmere”) pnblislied in 1831 in Gleanings in Science, VoL, III, page 111, 
states: “ The produce of the mines has hitherto been very limited. The annual 
quantity of metal smelted averages about 850 cwt.while it is stated in the 
Ajmere Gazetteer: “Mr. Wilder, the first Superintendent of Ajmere (in 1818), 
took the mines under direct management, and they produced annually from 10,000 
to 12,000 maunds of lead, which was sold at Rs. 11 per maund. 
“ The Ajmere magazine was the chief customer, and on its ceasing to take 
metal in 1846 the mines were closed." 
The mines consist of a number of pits sunk in a line several hundred yards 
long, extending from the hill to near the walls of the city. The ore occurs in a 
number of small roughly parallel veins running through a quartzite in nearly 
the same direction as the strike of the rocks. An adit level has also been driven 
into the hill, at a lower level, to drain these pits. 
A small quantity of lead ore has been extracted from a pit sunk near Ganes- 
pura, about 30 miles south of Ajmere. 
Some old lead workings occur at Indawas and Gudha, in Thana Ghazi, in the 
Uhvar territory. The former consists in a long open cutting from 20 to 30 feet 
deep, from which, apparently, a considerable quantity of ore has been raised. 
The workings are now filled with water. At the latter j)lace a small pocket of 
ore was recently discovered, but which on being worked was found to die out 
in every direction. 
Iron and Manganese .—Iron ore occurs in several localities, and some of the 
mines have been and are still extensively worked. 
The mines of Bhangarh in Ulwar still produce large quantities of ore. These 
are now the only source of iron for the numerous furnaces in the Ulwar terri¬ 
tory. The ore is a mixture of limonite, magnetite, and oxide of manganese, 
containing 59'67 per cent, of iron and 12'7 of manganese (Mr. Mallet’s 
analysis). 
The old and extensive mines near Rajgarh in Ulwar are not now worked. 
Large quantities of a superior iron ore have been raised at Karwar, near 
Uiiidaun, but the woi’kings are now abandoned, probably from the scai’city of fuel. 
There are some old iron workings near the jail at Ajmere, but the produce 
must have been very small. 
Iron ore is now worked to some extent near Gangar, in Oodeypore, and near 
Bhairompura, in Boondee. 
Niclcel and Cohalt .—Traces of nickel have been found in some of the iron ores 
from Bhangarh, but the pit from which the ore was taken has fallen together. 
An ore of cobalt called saita (or sehta) is found in the slate hills near Bahai 
in fine strings, and sparsely disseminated through the .slates, with pyrrhotite 
(magnetic iron pyrites) and copper pyrites. It is described in mineralogical 
works as Syepoorite (probably a mistake for Jyepoorite), sulphuret of cobalt 
(sulphur 36'36, cobalt 64' 64), The ore is used for colouring enamels, bangles, 
et c., of a blue colour. 
Zinc .—Large quantities are said to have been obtained from Jawar, in Oodey¬ 
pore, but as yet my examination of the country has not extended so far south 
as this.
