The most extensive of these mines ai-e those of Khetri and Singhana in 
Shaikhawati, Dariho in Ulwar, and the lead mine at the base of the Taragarh 
hill near Ajmere. The rest are, comparatively, very small. 
Copper .—That the old workings, both at Khetri and Singhana, were very 
extensive, and the quantity of ore raised considerable, is shown from the lai’ge 
and numerous heaps of slags resulting from the smelting of the copper ore. The 
hill on which the Singhana fort is built is formed, in a gi'eatpart, of these slags. 
The abandonment of the mines is attributed to the partial failure of the ore 
in depth and to the increased cost of working, and as the Jeypore Durbar would 
not reduce the royalties, the miners abandoned the mines and left the country. 
At jiresent a few men make a liAung by picking out some stones of ore left in 
the old workings; and a number of people are engaged in the manufacture of 
Lila (blue vitriol), Pitkhera (alum), and Kasis (copperas). 
The Khetri mines are situated a short distance north of the fort near the 
crest of a ridge of slates about 500 feet above the level of the plain. The mine 
is entered by several shafts of considerable depth, and which lead down to a 
gallery, said to be upwards of 2 miles in length. The direction of the level, as 
pointed out to me, appeared to be parallel to the strike of the slates. The ore 
now brought up fiom the old workings is copper pyrites ; it occurs in small strings, 
and disseminated through the slates. 
The Singhara mine is about 6 miles north of Khetri. It is entered by a wide 
gallery driven into a ridge of quartzite, in the same direction as the strike of 
the rocks, and near the top of the ridge several hundred feet above the level of 
the plain. This gallery is, in places, 40 to 50 yards wide and of a considerable
