visible for about a quarter of a mile with a thickness? of about 10 feet.^ 
In 1879 a sample sent to the Ceolojfical Museum by Mr. W. Ness, Mining; 
Engineer in charge of the Warora Collieries, was analysed by Mr. F. R. 
Mallet.2 In 1899 the rights to work this body of ore were secured by the 
Central Provinces Prospecting Syndicate, which commenced work on it 
in the same year. In fact this was the first manganese-ore deposit in 
the Central Provinces to be worked for export. In Plate 35 is given a 
sketch plan of the deposit reduced from an old plan and with recent 
additions by Mr. W. Whyte. The outcrop of manganese-ores has been 
traced practically continuously for about IJ miles in a general east- 
south-east direction, curling round to south-east at the south-east 
extremity of the band. The Parsoda deposit, distant some | mile to 
the south-south-east of this end, is no doubt only a continuation of 
this band ; for although the intervening ground is covered by alluvial 
soil, yet, according to Mr. W. Whyte of Mansar, fragments of ore can 
be found scattered on the surface of the ground along the line joining 
the two deposits. For about | of its length the ore crops out along the 
crest of a ridge which rises to a height of 350 feet above the plains at 
its highest point, namely the Grand Trigonometrical Station (G. T. S.) 
shown on the i inch map of the Nagpur district. 3 In the other 
forming the south-east end of the deposit, the ore-band descends nearly 
to the level of the plains and is exposed in several pits known as the 
Kamthi Lady Pits, the Satara Pits, and the South East Mound Pits, the 
last named being immediately to the north of the Mansar-Ramtek road. 
The ore-band continues to the south of this road, where it has been 
traced for 100 yards in a S. 40° E. direction in some pits recently 
opened up near the Central Provinces Prospecting Syndicate hospital ; 
whilst a trial pit 80 yards further to the S. 40° E. has shown angular talus- 
ore in alluvial clay. 
The area taken out on mining lease includes portions of the village- 
areas of Mansar, Khairi, Chargaon, and Parsoda, taken in order from 
north-west to south-east. The main part of the deposit on the ridge is 
divided between Mansar and Khairi, while the south-east end of the 
deposit north of the Mansar-Ramtek road, including the pits named 
above^ and a large part of the talus-ore pits that lie on the north-east 
side of the ore-band, is within Chargaon limits. The portion to the 
south of the above-mentioned road is in Parsoda limits.
