MANGANESE DEPOSITS OF INDIA : DESCRIPTIVE, [PaRT IV : 
4. Ramandrug Main Bed. 
(See Plates 44 and 45.) 
Tliis deposit is situated about a mile W. N. W. of Ramanamallai 
G. T. S., 3,256 feet, in the bay of the plateau immediately to the 
south of the Prospect Point spur. It possibly joins on to the No. 4 
deposit on the N. W. side of the Point underneath the laterite. There 
is the usual lateritic capping on the plateau here, and the top of the 
deposit is a few feet below the top and about 150 feet above the top of 
the Prospect Point ropeway. It is the biggest of the Ramandrugjdepo- 
sits and the one that was first opened up. The deposit has the usual 
N. N. W. strike of all the Ramandrug deposits, with a steep dip, 
which can be taken as averaging 65° across the middle section of the de- 
posit, into the interior of the syncline, i.e., to the E. N. E. The 
length of the deposit, from Prospect Point to where it disappears on 
the edge of the hill to the S. S. E., may be about 700 feet. 
The deposit is at present being worked by two benches parallel to 
the strike of the ore-body. One of these — the main bench — is about 
140 feet below the top of the plateau, and the other some 50 to 60 feet 
lower. The upper one is that shown in figure 76, and is some few feet 
below the base of the ore-body as seen on the working face. The tunnel 
driven into the working face for 66 feet, and the information it gives, 
have been noticed on page 1006. The ore is extracted by drilling 
and blasting, and stacked on this bench, where it is cleaned. Then 
it is lowered to the lower platform by one of two contrivances. 
One of these is a rough gravity incline with a double pair of 2-foot rails. 
The other, a more ambitious structure, was not finished at the time of 
my visit. It was 103 feet long at an angle of nearly 30°. The 
loaded ore -trolly is run on to rails on a cariiage, which is then 
lowered bodily, hauling up an empty trolly on a similar carriage with 
rails. At the bottom of the incline the trolly is run of? the carriage 
and run out to the loadnig station of the ropewaj'" at Prospect Point, 
to which there is a double track of rails. The waste from the 
southern part of the deposit is run out to the south on tram lines and 
tipped down a slope into the valley below. For the disposal of the 
waste from the north part it is intended to carry an elevated shoot fron: 
the main bench over the lower bench, so as to tip the waste down the
