The existence of manganese- ore at Gosalpur seems to have been 
known for a long time to the local glass makers, although they did not 
of course, call it by this name. Its occurrence was first brought to the 
notice of Government by Mr. W. G. Olpherts in 1875. Later it was 
described by Medlicott in a paper by Mallet', who makes further re- 
ference to it in a latter paper.2 According to Bose,3 who gives a 
large scale plan of the Gosalpur pyrolusite area, — 
'Except in tlie ground just in front of the dak bungalow (some 50 yards to 
south-east of it), the pyrolusite occurs here in and among the Gosalpur quartzites, 
usually soft, decomposed, and blue-coated at the outcrop. Sometimes the rock 
is hard, and either white or red in colour, assuming in the latter case the appear- 
ance of jasper. Wherever such is the case, manganess-ores are wanting. Fre- 
quently the rock appears as a conglomerate or breccia, fi'agments of soft, decom- 
posed (sometimes almost powdery) quartzite being cemented together, as it were, 
by a matrix of manganese or iron-ore. Wherever such a rock crops out, manga- 
nese or iron-ore is found in some quantity by digging close to it through the soil- 
cap under which it passes, the nature of the ore being determined by that of the 
"matrix " at the outcrop. 
' The quartzites have the general. . .strike of the area, viz., N. E. — S. W. The 
dip is obscure ; it was found to be very high (about 80") pointing S. E., some 150 
yards north of the dak bungalow.' 
After this Mr. Bose gives the details of a number of pits dug by himself. 
The ones given on page 812, may be taken as typical of the sections 
recorded by Mr. Bose. Further, he sub-divides the ore-bearing area
