280 Lead Ores in the Cuddapah District. [No. 8, new series. 



On the western side of the lode, and at a distance of about § of 

 a mile from it, there occurs a branch vein, this is marked on the 

 map a little south east of the village of Nagsanpilly. 



At the point of observation it is split into two portions about 2 

 feet apart, each being of a thickness of 4 inches average. 



Being of small dimensions it is rich in mineral, the whole being 

 made up of ore and clay, there is also a considerable admixture of 

 carbonate of Copper. 



The direction of it is north east and south west with an underlie 

 of 45° to the south east. 



Its course traverses a series of ridges and nullahs and in this 

 respect is very favorably circumstanced for working. 



The place where opened by my excavations is situated about 

 150 feet above the level of the plain, so that a considerable extent 

 could be worked vertically by means of headings into the hill side 

 without any fear of interruption from water, and with the greatest 

 possible facility for getting rid of the debris ; longitudinally also a 

 great extent could be mined under the same advantageous circum- 

 stances on account of the undulating surface of the country. 



The part at present exposed is.l£ mile from the point where, if 

 its present direction is maintained, a junction would be effected 

 with the main lode, approaching which it may be expected to in- 

 crease in richness. 



In the opposite direction there is about 1J mile of the same un- 

 dulating country it probably traverses before reaching the plain. 



There is every reason to believe it will not be found to die out 

 in this last named direction, inasmuch as the mineral I discovered 

 to occur again to the south at about 7 miles distant, and where the 

 course of it, if continued, would intersect the Penrair river. 



The range of hills traversed by the southern portion of the main 

 lode as also by this supplementary branch is a portion of that 

 called Lunkamulla, and so named on the Ordnance map. The 

 place alluded to in my previous report under this name is the 

 branch vein now described. 



Close to the village of Coteloor on the northern bank of the 

 Pennair river, a vein of white quartz crosses the bed of the river 

 nearly at right angles, in this substance occur tolerably thickly 

 scattered large crystals of cubical Galena.
