The present drift was, I believe, begun under the instructions of Captain 
Impey, formerly Political Agent at Ulwar, to drain the pits sunk by the natives 
in the bill side. 
The copper occui’S in the form of copper pyrites, mixed with arsenical iron. 
The mine is now nearly abandoned and but little ore is to be seen. I bad some 
difficulty in finding a bit the size of a hazel nut. 
Blue vitriol, alum, and copperas are manufactured at the mine. 
I found traces of copper in some slates on the same geological horizon in the 
ridge a short distance west of Daribo. 
The Bhangarh workings consist of two or three small pits now fallen together. 
The workings of Knshalgarh, Baghani, and Partabgarh have been abandoned for 
many years. The natives say that at the two latter places the workings were 
very extensive, and that the mine fell together suddenly, burying a largo number 
of men. 
A few small pits have been sunk in the quartzites west of Nabaro and west 
of Udhala, both near Sainthal in the Jeypore territory, from which a little copper 
ore may have been extracted, as the debris on the sui’faco is stained with C023per. 
Near Lalsot, in Jeypore territory, a small hole has been made in the face of 
the scarp, and the stones about are stained with copjjor. At G-arh, about 15 miles 
north-east of the above, a pit has been sunk to the depth of about 20 or 30 feet. 
There were traces of copper round the mouth of the pit. In both those cases, 
although the rocks surrounding the pits were bare and unbroken, I could fin<l 
no trace of a vein or even of copiper in any direction a yard from the pit’s 
mouth. 
At Nithahar, in the Bhnrtpore territory, a short level has been driven into 
the hill and a small quantity of copiper raised. 
A small pit has been sunk in the quartzites about 2 miles east of Datunda in 
the Boondeo territory. The stones are stained with cojoper, but I should not 
think sufficient was raised to pay the costs of the pit. 
At Rewara, near Grangapur, in Oodeyporo, a number of small p)its are sunk 
in the schists in a north and south line for nearly a mile in length. These psits 
have all fallen together, or are filled with water. The copper appears to have 
been smelted on the spot, but judging from the small quantity of slags, no very 
large amount of ore was raised. 
I observed traces of copiper in the old iron workings near the jail at Ajmere, 
also at Tasing in the Mandan hills, and at Jasingpura near the railway, both in 
the Ulwar territory. 
Oap)tain C. J. Dixon, in a report dated 8th May 1835, published in the Jour¬ 
nal of the Asiatic Society, Vol. IV, page 583, mentions the occurrence of copper 
ore at three localities near Ajmere, viz., at Gugra, 4 miles north-north-east of 
Ajmere, Riijgarh, 12 miles south-south-west of this, and at Eajauri, 10 miles 
south of Ajmere. 
Galena.—Tihe only lead mine of any importance occurs at the base of the 
Taragarh hill near Ajmere. Foiunerly these mines produced large quantities of 
lead, although there appears to be some discrepancy in the accounts as to the 
amount. Thus, Captain 0. J. Dixon, in a paper (“ Some account of the lead
